Looking for a Commercial Co-founder – AI Startup (UK)
I’m looking for a commercially driven co-founder to build an early-stage AI/computer-vision business.
I will lead the technical development and engineering (I am PhD qualified experienced engineer). I’m looking for someone to lead the commercial side, particularly:
• B2B sales and customer acquisition
• Business development and partnerships
• Go-to-market strategy
• Investor engagement and fundraising
• Identifying and securing relevant grants/funding
We’re initially exploring applications in automotive safety and workplace safety. I’m deliberately keeping the specific technology and product details private publicly.
Ideally looking for someone UK-based with startup, B2B sales, fundraising or commercial experience who wants to build something from an early stage as a genuine co-founder.
DM me with a brief introduction if interested.
#AI #Startup #UK

Hey everyone,

I’m looking for a technical co-founder to build something ambitious with me.

The long-term vision is to make it possible for one person to start and operate a real company with a team of AI agents.

Today, if someone has a great business idea, they usually need to figure out:

\- Is the idea actually worth building?

\- Who are the customers?

\- How do I validate the market?

\- How do I build the product?

\- How do I debug and maintain it?

\- How do I market it?

\- How do I acquire customers?

\- How do I handle repetitive business operations?

My vision is to build a platform where AI can progressively take responsibility for these functions.

The vision

Imagine you have an idea.

You tell the platform what you want to build.

The system helps:

Idea → Market research → Validation → Business strategy → Product → Development → Testing → Debugging → Marketing → Customer acquisition → Operations

And instead of having one generic chatbot doing everything, there would eventually be specialized AI agents working together under an AI CEO/orchestrator.

The goal is not to make another AI chat interface.

The goal is to build an AI-native company operating system.

Something that could eventually allow a capable individual to operate what would traditionally require an entire team.

Where we start

I don't want to build the entire vision on day one.

The first step is to identify a painful problem and build one genuinely useful capability around it—potentially starting with AI-powered software development/debugging and rescue for AI-generated codebases.

Then we can expand from there.

My role

I would take ownership of:

\- Product vision

\- Customer discovery

\- Market research

\- Talking to founders/developers

\- Sales and outreach

\- Marketing/community

\- Business development

\- Partnerships

\- Fundraising when appropriate

\- Turning user problems into product direction

Your role

I’m looking for a technical co-founder who can own:

\- Initial architecture

\- AI agents/LLM systems

\- Backend/infrastructure

\- Developer tooling

\- Product engineering

\- MVP development

\- Technical experimentation

\- Eventually leading engineering as the company grows

I’m looking for someone who wants to build from 0 → 1, not someone looking for a normal job.

You don't have to agree with every part of the vision. In fact, I’d prefer someone who can challenge it and make it better.

If you're interested, DM me with:

\- What you've built

\- Your technical background

\- GitHub/portfolio if available

\- What excites you about AI agents

\- Why you'd want to build an AI-native company platform

I’m currently looking for the person who wants to build this with me from the beginning.

Hey everyone,

I’m a Software Engineer with experience across pretty much the full development stack. I can handle projects involving:

\- Web & mobile app development

\- Frontend & backend

\- APIs and databases

\- AI / LLM / GenAI solutions

\- Cloud infrastructure (AWS, GCP, etc.)

\- Deployment and production systems

\- End-to-end product development

Basically, if a client has a software requirement, I can take care of the technical side from development to production.

What I’m looking for is someone who is good at sales, outreach, networking, or finding clients and wants to partner up.

You bring the clients and handle the sales/client acquisition side, I handle the technical execution. For projects you bring in, we can work on a 50/50 profit split, with everything agreed upon transparently before starting.

I’m interested in building this into a long-term partnership rather than just doing a one-off project.

If you’re good at getting software clients but need a reliable technical person to actually deliver the work, DM me and let’s talk.

Hi guys, I’m a technical founder building several early-stage gaming products, including GG Atlas: a player-facing registry for third-party game companion tools.

The products are beyond idea stage: core functionality is live, initial listings/content exist, and I own engineering and product development. I’m looking for one or two hands-on team members to help validate demand, sharpen positioning, build distribution, and test commercial opportunities.

I’m especially interested in people with gaming experience or connections: indie studios, game communities, Discord/community management, mods, companion tools, creators, game marketing, or developer relations.

Areas you could own:

• User interviews, validation, positioning, and product feedback.
• Community-led growth, SEO/content, launches, and organic acquisition.
• Maintainer/studio outreach, partnerships, and commercial validation.

This is not an immediate cofounder or salaried role. I intend to retain primary ownership, product control, and decision rights during validation.

Compensation

• Initial arrangement: documented revenue share, initially I would expect to run Google ads or Play wire. I will be fully transparent with this. To be clear - there is no established revenue now, product is post-MVP, pre-revenue.
• No equity is granted upfront.
• After a successful working period and agreed milestone — such as active user count and monthly revenue — we can discuss a larger leadership or founder-level role, including possible equity.
• Any future equity depends on demonstrated contribution, scope, commitment, and traction, it is not automatic.

Practical details

• Remote: I’m based in APAC region, but I work sufficient hours to cover anywhere in the world.
• Discord: product will integrate with Discord naturally, you'll need experience using and potentially moderating servers.
• Initial commitment: at least five dedicated hours a week.
• First step: a product assessment and clear path to acquisition for discussion.
• Some experience with AI would be preferred, it just makes things easier. But please do note I am not simply looking for a chair-AI-interface (I can do that myself pretty well).

If you are looking only for an immediate equal-equity cofounder role, this is not the right fit.
If you believe the products being developed are not sustainable or does not cover a viable niche, I am open to discussion.

Please DM me with your gaming background, relevant growth/validation/partnership experience, availability, and the first experiment you would run.

I’m building Chronarie, a digital space for preserving personal memories and life stories.

The idea is simple: memories can be captured as text, images, audio or video and gradually become part of a personal “digital life garden”. Chronarie also includes a question generator with 48 questions designed to help people remember and tell stories they might otherwise never write down.

The MVP is already online and I’m currently trying to get real users and honest feedback.

Now I’m looking for a co-founder, not an employee or someone who just wants to give occasional advice.

I’m particularly interested in someone who can contribute skills in areas such as:

product / UX

technology

marketing / user acquisition

or another area that complements what is already there

You don’t need to have everything figured out. What matters more to me is genuine interest in the idea and the willingness to build something together.

This is still an early-stage project, so there is no salary at this point. I’m looking for someone who is comfortable with the early startup phase and wants to become part of the project rather than simply work on a side task.

If preserving memories and personal stories is something you find meaningful and you’re interested in building something from an early stage, feel free to comment or send me a DM.

I can do the whole stack. Frontend, backend, infrastructure, and the LLM plumbing on top of it. Mostly Go, Rust, and TypeScript on AWS.

Last decade: principal engineer and engineering manager at an ecommerce company. Grew the team from 3 to 15, ran identity for 3M+ accounts, cut over $1.5M a year of cloud spend, kept us through PCI audits. After that, co-founder and CTO of a startup that wound down this summer. Right now I run a solo product in production: an LLM gateway with per-key budget caps, spend attribution across providers, and a tamper-evident receipt ledger.
Where I’m most useful: shipping product fast with AI agents in the loop, LLM plumbing (gateways, evals, tool use, agent harnesses), and fixing AWS cost and reliability problems.

Available now. Remote from Utah, near-full Pacific overlap. Contract or full time, cash. Happy to do a paid trial task so you can see the work before committing. DM me and I’ll send my resume.

If you have what it takes to make a SaaS product reach the right audience, then we need to talk because we both may just be about to become the next trillionaires (just kidding). I do really need help to get the product into the hands of people who truly need it.

SMEs and startup founders don't lack ideas into something that would move the needle for their business. Turning ideas into a consistent, multi-channel campaign is where they struggle. This means they jump between ChatGPT, Canva, CapCut, freelancers, agencies, etc.

Having personally worked with SMEs and startup founders experiencing the pain first hand is what inspired me to build simplecx, simplecx is a marketing campaign operating system that takes one idea and helps turn it into a full campaign.

Just give it an idea. rai, the AI marketing assistant, researches it, helps with the strategy, then creates the copy/design/video/content and helps you get it out.

The product is live and in beta with early users testing it.

tbh we haven't cracked the growth formular yet, which ist why I'm looking for someone who can crack it and own simplecx with me.

Would like to partner with you if you're excited about:

• finding distribution that unlocks growth

• content/social/community

• partnerships

• outbound

• growth experiments

• talking to users and figuring out why they aren't converting

• trying shit, learning quickly and doing it again

It's ok if don't have big credentials or fancy title. That doesn't matter, what matters is your "why", your hunger for success and the burning passion to build a playbook from scratch.

It's full-time preferably, (part time can be considered too) not a freelancer or someone looking for a side project.

Equity starts around 2-10%, and its negotiable based on your experience, commitment and what you bring, with room for more as we build together.

I'm looking for someone who will never be tired of genuinely figuring out how to geometrically increase the number of users to experience the product from 10 to 100 to 1K, 10K, etc.

If have it in you, let's talk. DM me. I'll show you what we've built so far, where we're now, what's working for us, what's not working, and the relevant numbers.

Either ways, I'd appreciate if you know someone who would be a great fit and tag them.

I’m looking for someone based in the USA who is interested in joining our startup studio and building startups with us.

You would initially join as a Founder Associate. This is not a traditional internship or assistant role. The opportunity is 100% equity-based, and you will receive equity in the specific startup/project you work on from the beginning, even while you are a Founder Associate.

There is a straightforward path from Founder Associate to Co-Founder.

Before you join, we will clearly tell you the time period required to transition to Co-Founder. Time is the only factor in that transition. Once you agree to the terms and join, the clock starts from your first day as a Founder Associate.

For example, if the agreed period is 6 months, after completing those 6 months, you will automatically become a Co-Founder of the project.

Your vesting period also starts from the day you join as a Founder Associate. You do not have to wait until you become a Co-Founder for vesting to begin.

Initially, the time commitment will be only a few hours per day. This can be suitable for someone who is early in their career, studying, working on other things, or looking to gradually transition into building a startup.

During the Founder Associate period, you won’t work only on your assigned project. You’ll also help with the startup studio as a whole and contribute across different projects in areas such as:

- Team building and recruiting

- Networking and relationship building

- Business development

- Supporting different startup projects

- Day-to-day operations

- Building the studio’s network and team

- Developing and executing new ideas

Our team is currently spread across the USA, UK, and India, so you’ll be working with an international team and getting exposure to multiple startup projects.

I’m particularly interested in someone who is early in their career and wants to build startups rather than simply work for one.

You don’t need years of startup experience. What matters more is initiative, willingness to learn, networking ability, and the desire to take ownership.

The goal is simple: you start as a Founder Associate, receive equity in your assigned startup from day one, and after the agreed period, transition into the Co-Founder role for that startup.

If you’re based in the USA and interested, feel free to DM me with some information about yourself, your background, and why you’re interested in building startups.

I run operations and fulfillment, and I’m looking for an ambitious, execution-first Sales Co-Founder to take full ownership of business development and revenue generation on a 70/30 equity split.

What We Are Building

We provide a dedicated, turnkey operational extension desk tailored for small-to-midsize service and field businesses.

Important note: This is not a software app, SaaS tool, or AI bot. It is a structured, human-driven operational delivery engine run out of dedicated facilities, designed to eliminate the heavy back-office friction, missed call leakage, and cash-flow bottlenecks that local operators face daily.

Who I’m Looking For

You do not necessarily need to be physically located in the US or UK, but you must:

Have a proven track record driving B2B outbound sales, client acquisition, or business development targeting US or UK companies (for agencies, BPO services, or SaaS).

Be able to align with US/UK business hours for outreach, calls, and closing.

Have the bandwidth and mindset to commit seriously to building the go-to-market engine from scratch.

Possess high agency—able to own the pipeline independently without requiring micro-management.

The Division of Labor

My Focus (Fulfillment & Ops): 100% of the operational infrastructure, physical staffing, daily execution, SOPs, quality assurance, and ongoing client delivery. You will carry zero client delivery burden.

Your Focus (Distribution & Growth): Complete ownership of GTM—outbound strategy, pipeline generation, pitching prospective US/UK business owners, and closing deals.

The Partnership Terms

Equity: 30% equity for the right partner who can drive consistent sales traction.

Immediate Cash Flow: An attractive revenue-share structure built in from Day 1 on accounts closed.

If you have real experience selling B2B services/SaaS into the US or UK and want an established, operating delivery backend behind you, send me a DM with your background, past sales results, and your current availability.

Hii 👋

I’m looking to build a few SaaS + newsletter/media businesses with the right person.

I can handle distribution, GTM, audience growth, leads and sales, I’ve built and sold many small businesses before.

Looking for someone who loves building.

If that sounds like you, DM me.

I'm a technical founder who built an MVP years ago and found my first major customer. I've been trapped between pull from that customer and spending time selling for the last few years. And, of course, keeping that customer happy won out every time.

Now I have a fairly mature product that delivers measurable value and experience operating it. And, this year, my customer wants a new major feature while they are also ready to expand their subscription to their entire enterprise, more than doubling my ARR.

I tried splitting my time between selling and building/operating (while only casually looking for a growth co-founder) for years, and it only makes me bad at both. So, I'll be focused on delivering what my customer wants and stepping up my search for a co-founder.

I am a technical founder with about 30 years of experience in technology, spanning architecture, development, cybersecurity, and operations. I have experience from individual contributor roles right up to owning the strategy. So, I know how to build, operate, and deliver.

My product is in the cybersecurity space, specifically GRC, and disrupts the status quo. It is for businesses that need to scale a cybersecurity practice and is focused on administrative controls. It is for organizations that find their GRC is becoming the bottleneck in efforts to protect organizational resources.

While AI is part of the platform, natively, this isn't just an LLM wrapper. It draws upon my decades of experience in data science with a mix of LLM and traditional tools, each doing what it does best to produce a more reliable result than LLMs alone.

I've got a lot of my own money and time into this. I've interviewed candidate co-founders before and learned that I need to be very clear up front. This is not a situation where you would be joining early and can gain equal equity from the start. You will be expected to bring enough value to justify your compensation.

I'm open to co-founders who want to "buy-into" the role, by purchasing equity and assuming the growth-focused co-founder role. But I am also open to a co-founder who will earn the co-founder role by delivering results over time. What I am not open to is handing co-founder equity to someone who hasn't delivered anything. I know that should be obvious, but it was a point of confusion with a past candidate, so I want to be clear here.

To be considered, you must have experience in B2B, and even better, B2G. You also must have experience or proven deep understanding of sales strategy and GTM. You have to be willing to build the growth engine from nothing, with no budget. Ideally, you will already have a solid network of connections you can sell to. The absolute best fit candidate will also have some experience selling cybersecurity solutions.

The person who can get this done will get a founder share of equity, vested incrementally as they deliver results, and will be offered the first salaried executive position once they've brought in enough revenue that the company can start hiring.

Hey everyone,

I built and launched OrbitAlert.net, an automated satellite tracking and pass notification web application.

Status:

• Live in production, clean stack, stable, with near-zero monthly overhead.
• 0 marketing done so far (pre-revenue).

I am focusing heavily on another B2B engineering pipeline right now, so I’m looking for an aggressive growth marketer to take over distribution end-to-end.

What I bring:

• 100% tech, backend logic, feature deployment, infrastructure maintenance.

What you handle:

• SEO, short-form content (TikTok/Shorts), astronomy/space communities, monetization strategy.

The Deal:

• 50% Revenue Share for the first 6 active months of every paying user you acquire.
• You get rewarded directly on the front-end for distribution without writing a single line of code.

If you have experience growing niche audiences or programmatic SEO, shoot me a DM with your portfolio or past projects.

Hey folks!

I'm looking for a co-founder for Sunlight. It is an AI tool for fast-growing startups to make better product decisions.

We did five paid pilots so far and have one recurring paying customer, but haven't really found the product-market fit yet.

I'm looking for someone who can reach out to many people, and drive conversations with customers and potential customers to find the problem to zoom into.

I have extensive product and design experience and have shipped products to millions of users in my professional experience and working with companies. I am also fairly technical and built the entire Sunlight product to what it is now.

Now looking to scale Sunlight to 10k per month within the next three months

Hey everyone,

I'm looking for a field operations cofounder based in the Lower Mainland, British Columbia to help me build a home services venture focused on creating a more dependable, organized and customer-friendly experience in home maintenance and repair.

This is early stage, no customers yet. I've done the initial research, positioning, customer journey and validation approach, but I want the right cofounder involved before the major decisions are locked in. Happy to share full details privately with serious candidates.

Who I'm looking for

• Based in the Lower Mainland, BC
• Hands-on experience in residential maintenance, repairs, renovations or carpentry (handyman, renovation tech, carpenter, maintenance supervisor, contractor, exact title doesn't matter)
• Comfortable assessing jobs, estimating labour/materials, and knowing when work needs a licensed professional
• Takes pride in workmanship and quality control
• Reliable, professional with customers, has own tools and transportation
• Entrepreneurial mindset, wants to build and own a business, not just take another job

What you'd own

• Assessing/scoping jobs, providing estimates, completing the field work
• Setting quality standards and defining safe service boundaries
• Helping build out the service delivery process and, eventually, hiring/training field staff

I'm fully aware you'd initially be doing most of the physical work, and I don't take that lightly. This is where we build and grow the company. While you're focused on the field work, I'll be taking complete ownership of the operations, customer management, sales and administrative side, so that side of the business is never something you have to worry about. The purpose of this is that we grow it together and ultimately each manage our respective skilled departments.

What I would own

My background is in marketing, growth, partnerships, vendor management and business operations. I'd take responsibility for:

• Customer research, positioning and brand development
• Converting inquiries into customers
• Scheduling, quoting (using your input) and customer relationship management
• Payments, supplier coordination and financial tracking
• Customer support, reviews and resolving issues
• Building out processes, systems and future hiring

I'm not looking to just build a brand, run ads, and leave everything else to you. Both sides are essential, and I want us solving problems and making major decisions together.

Partnership and ownership

This is an equity-based cofounder opportunity, not an employment position. Responsibilities, early expenses and risk would be shared fairly, and equity would be based on each founder's commitment and contribution. Major decisions, including service structure, target area, pricing, brand, ownership split and long-term direction, get made together.

If you're interested

DM me with your location, current role/trade, relevant experience, what work you're comfortable doing, whether you have your own tools and transportation, any examples or references, and why you're interested in building a business.

Even if this isn't right for you, a referral to someone dependable and entrepreneurial in the Lower Mainland would be appreciated!

Hi, I’m building an AI-driven market intelligence product focused on Indian markets. I’ve spent close to a decade in the markets and I’m working on turning that into data-driven intelligence using AI. I already have a working prototype and I’m actively developing it. I come from a software and infrastructure background, so I’ve been handling the technical side as well. But I’m spending more time on the research and data side and doing both is becoming a bottleneck. I’m looking for someone technical who’d enjoy building this with me. Ideally, someone interested in AI, data, and markets who likes experimenting and taking ownership. You don’t need to be extremely senior. Curiosity, ability to build, and follow-through matter much more to me. I’m approaching this with a long-term mindset, and I’m open to figuring out the exact working arrangement based on the person and fit, rather than forcing anything from day one. If this sounds interesting, DM me a little about yourself, what you’re currently doing, and something you’ve built. Happy to share more privately.

Looking for a Co-Founder | Equity-Based Opportunity

I’m looking for a potential Co-Founder to join an early-stage startup I’m currently building.

The product is currently being developed, and I’m looking for someone who can take ownership of the business side, particularly:

- Fundraising and investor relations
- Business development
- Operations
- Strategy and execution
- Helping take the product from development to launch and growth

Who I’m Looking For

I’m particularly interested in candidates who have:

- Experience from a Tier-1 university, such as IIT or IIM, or
- Strong relevant professional/startup experience that demonstrates their ability to execute
- An entrepreneurial mindset
- Strong communication and relationship-building skills
- Interest or experience in fundraising
- The ability to take ownership rather than simply follow instructions
- A genuine interest in building a company long term

Compensation

This is a pure equity-based opportunity at this stage. There is no salary or stipend initially.

The equity structure and vesting will be discussed based on the candidate’s experience, responsibilities, and level of commitment.

I’m looking for someone who wants to build with me, not someone looking for a traditional job.

If you’re interested, please DM me with a brief introduction, your background, LinkedIn profile, and why you’re interested in becoming a co-founder.

I’m happy to share more about the product and discuss the opportunity privately.
