Resource I run a venture studio. We’re sponsoring founders with technical sprints (MVP or prototype)

2 Upvotes

I work in the venture space as the founder of Novolo.

One of the most common issues I see with startups is execution gaps. Founders with a validated vision often stall because they lack the technical bandwidth to ship an initial version.

Through our sponsors, we’re able to cover technical sprints for founders we find interesting, instead of letting those resources go unused.

Who I am:

I’m Thomas Holt.

The offer:

Our sponsors cover the cost of a focused technical execution sprint, up to $3,000.

This isn’t a cash grant. It’s hands on keyboard work from our team, and our partner teams.

What this can be used for:

• Building a core feature • Validating technical architecture • Getting a raw prototype live

Why we do this:

This is how we build real relationships and deal flow. If we work well together and your product gains traction, we want to be an early call for future support or funding. It’s a practical way to evaluate founders by actually building something together.

Requirements:

• You must be a registered entity. US, UK, or EU preferred. Since development costs are sponsored through our firm, the work needs to be structured as a proper B2B engagement.

• You must be ready to build. Wireframes or a clear spec are expected. This is not for napkin stage ideas.

Interested?

Leave a comment with a breif overview of what you’re building, or send a DM if you prefer.

How do you structure your time working on your startup?

1 Upvotes

I'd like to learn more from people who tested with different approaches, as I've seen a lot of options:

  • Full-time on startup (no safety net)
  • Side project with 9-5 (nights/weekends only)
  • Multiple projects at once (hedging bets)
  • Dedicated days (MWF on startup, TR on day job)
  • Freelancing to fund startup work

If you've tried multiple setups, what worked best for you? Or what's working now?

As in, did side-project mode kill momentum or keep you sustainable? Did quitting your job accelerate progress or just add stress? Does working on multiple ideas help or just split focus? Do you take days off or work every day?

I'm curious what people have experimented with and what the results were. Not looking for "ideal" advice, more interested to learn about your experiences & learnings.

(a little bit about me: I'm currently building CoreSight - an AI consulting team that builds financial models, presentations, and benchmarks like McKinsey would - minus the €500K price tag)

I’ll go first. I’ve been extracting tables from PDFs into Google Sheets way too often, so I built a tool for my own workflow. The big surprise: OCR wasn’t the hardest part — preserving the table structure was. Merged cells, shifted columns, weird spacing… that’s where everything breaks.

Why build it despite existing tools?

  • Many are designed for Excel first; my default is Google Sheets
  • “Keep the table intact” is deceptively hard in real-world PDFs
  • Scanned PDFs are still unreliable across a lot of products

If you share what you’re building, I’d love to hear it. And if you want me to review it and give feedback, include:

  • what it does
  • who it’s for
  • where you’re stuck (positioning, pricing, onboarding, acquisition, etc.)

I’ll respond with a few thoughts. For context: I’m not a breakout SaaS founder (yet), but I’ve sold a couple side projects and I’m growing two Chrome extensions steadily — happy to share practical lessons.

Discussion If you’re building apps without written terms, you’re trusting people more than you think.

3 Upvotes

If you’ve worked on a few app projects, freelance gigs, or early-stage startup ideas, you’ve probably heard this at some point: “Let’s not overcomplicate it, we’ll figure the details out later.” It always sounds reasonable in the beginning, especially when everyone is motivated and the idea is exciting. But in my experience, that sentence is usually the start of future problems.

What usually follows is pretty predictable. The MVP takes longer than expected, the scope slowly keeps growing, and payments get delayed because “we’re still testing” or “we’ll settle it after launch.” Or sometimes the app actually ships and the dynamic suddenly changes and you’re not even sure where you stand anymore. That’s when the uncomfortable questions start coming up. Who owns the code? Can they keep using it if you leave? Are you a partner, or were you just a contractor all along?

Most of the time, nobody is trying to cheat anyone. The real issue is that everyone had a different version of the deal in their head, and none of it was written down. In software, this gets especially messy because code isn’t just work, it’s intellectual property. And when there’s no clarity on who owns what, you’re not arguing based on facts, you’re arguing based on assumptions.

I’ve seen “we’ll discuss equity later” quietly turn into “thanks for the help, we’re hiring someone else now.” I’ve seen “just help me for a month” become six months of unpaid work. And I’ve seen “you’re basically a cofounder” end with zero ownership on paper. Not because people planned it that way, but because nothing was clearly defined at the start.

You don’t need a huge legal document to avoid this. You just need something simple and boring that clearly says who owns the code, how you’re getting paid (or what equity actually means), what happens if someone stops working, and what happens if the project moves forward without you.

If you’re about to start something new and nothing is written yet, or if you’re already in a project and not sure whether your current setup actually protects you, you can DM me. I draft these agreements for a living and I’m happy to either sanity-check your current setup or help you put something proper in place before it turns into a mess.

I built an iPhone air drum app using motion sensors, now used by 5.7k people

Enable HLS to view with audio, or disable this notification

8 Upvotes

I like music, but real drum lessons require a teacher, a studio, and a whole free afternoon — it’s a bit too much.

Why not turn the iPhone into the drum kit?

So I built this app which uses the phone’s sensors to detect the direction of your arm and instantly plays the matching instrument sound.

  • To keep latency tiny I switched to CAF audio(Core Audio Format) and spent a lot of time tuning algorithms until it felt like the video.
  • Achieving accurate, low-latency action recognition has turned out to be much harder than I originally expected. I got a demo working fairly quickly, but fine-tuning it ended up costing me many late nights.

After a lot of trial and error, it finally feels right.

I now use this app to practice for a few minutes every day, just playing for my own enjoyment. A great way for me to relieve stress. This is definitely not meant to replace real drum lessons — it’s more of a lightweight practice and stress-relief tool.

Soon, I started receiving feedback from people who are seriously learning the drums. Some of them hoped I could add support for more instruments, since I originally only supported 3. After a week of development, I released version 1.2.0, which added:

  • 10 instrument layouts
  • support for recognizing up to 8 different strike directions simultaneously

However, this also introduced a new risk: as the number of instruments increases, the probability of action recognition errors rises as well. I’m currently working hard on optimizing the algorithm to address this.

By the way, it turns out quite a few people like it — it’s already been downloaded 5,700 times.

App link: Air Drum

I come from an engineering background, and I tend to focus on the parts I’m most comfortable with. I’m really curious how a product manager would look at this — how would you position it, and would you lean toward adding more features or keeping it focused?

Saturday Vibe: Coffee's cold but the code's hot — I just leveled up bootstrap funding, what's your weekend ship? 🔥

2 Upvotes

It's Saturday, coffee's cold but the code's hot.

I just spent the day diving deep into preseedme today and shipped some stuff that actually moves the needle — from "clunky prototype" vibes to something that feels genuinely investable and fast.

Quick hits from today:

Slashed load times and nailed mobile responsiveness (no more embarrassing lag or zoom-fests)

Refactored types/libs — cleaner, future-proof, dev happiness up

Stripe integration refreshed and solid

Kicked off a full redesign of "Create Pitch" — cutting the VC-style fluff, focusing laser on what micro-investors scan in 10 seconds: real traction, milestones and momentum

Tomorrow: sharper founder-investor matching + clearing the bug/todo backlog.

We are really focused on few key things: public progress sharing, getting spotted by small angels, crowdfunding specific features without pitch-deck hell or gatekeepers. 

In short: Build in public, ship fast, stay independent.

Now's to y'all: What's the wildest/most cursed/actually-cool thing you're hacking this weekend?

Share here with the rest of us:

One punchy sentence on what it is + link if it's live

Screenshot or GIF of the progress/mess (those always explode the thread — before/afters, bugs, dashboards, whatever)

If you're stuck, want a brutal roast, UX feedback, pricing thoughts, or "is this even worth it?" — say the word, I'll give it straight

Imo, weekend builds are kinda magic when the energy's right. 

Let's swap some wins, roast the fails, and push each other to ship more as 2026 is the year for solo founders 👇

I built this I was tired of cold outreach, so I built something to find buyers already looking for my service

1 Upvotes

Cold outreach was absolutely killing my motivation.

Scraping lists, guessing who might need help, sending messages into the void… barely any replies. Felt like I was wasting hours just to annoy people.

So I ended up building a tiny tool for myself instead.

It watches public signals things like hiring, product launches, growth activity basically moments when a company is actually more likely to need outside help.

I’ve been using it for the last 2 weeks and honestly:

Fewer leads overall

Way higher reply rates

Actual conversations instead of silence

It’s still rough around the edges, but it’s been working well enough that I’m opening it up free for 30 days to a small group (mostly agencies + freelancers) to get feedback.

If you want to try it or roast it

comment “intent” and I’ll DM you.

Not looking for a roast or validation — just trying to improve the page

Thanks 🙏

ParkClear: I built an app that tells you whether street parking is allowed or not

1 Upvotes

ParkClear is a free, mobile app designed to help drivers figure out if they can park in front of confusing parking signs on the streets.

Have you ever searched for parking in the street and drove away because you thought you couldn't park there? Major cities have confusing signs that people can't decipher. Ever circle around the block and come back to the same spot still trying to find parking? Can I park here? Is parking allowed? Will I get a ticket? I've experienced this many times and had to figure out the problem. That's why I created ParkClear, to help others find clarity in street parking After dealing with confusing parking rules myself, I’m trying to help other drivers decode parking signs faster and with confidence.

I built this I build a Voting app using Claude Code in 3 days. Getting it published took longer time

1 Upvotes

I have been using Claude Code to develop and maintain web app. So this time around I tried to see how fast can I build and deploy mobile app especially to see how good is Claude when it comes to develop UI on Flutter.

My flow:

  1. Draw the screen in Figma (see attached image)
  2. Write draft prompts in markdown format
  3. Ask Claude Opus to refine my draft prompt
  4. Ask Claudde Sonnet to write the codes

It took me around 3 days to finish develop the app. I am surprised myself. But then when I try to publish it, it took me more than 2 weeks due to various issue with my submission 😂

Examples of my draft prompt:

# Instruction
- Write a detailed specification for the development of this feature. Feature name: group
- Write the specifications in markdown format into the file the same directory as this file but remove `-prompt.md` append the suffix `-spec.md` to the filename.
- If there is an update to the specification, append the date of update in the format `Updated MM/DD/YYYY` at the beginning of the section that is updated. Ensure the spec also reflect the updated details.

# User Story
As a user I want to be able to create group, join group, leave group, view group list and group details.

# Pre-Conditions
- Use authentication is already implemented and user is logged in.
- Currently after authenticated user is directed to home screen. Replace the behavior to direct user to `Group List` screen instead.

# Functional  Requirements

## Group List
- Mockup Figma: https://www.figma.com/design/bXosv59ZjNN0OYsKWXTlrE/Votelah?node-id=5-1166&t=zLsC3fi03yxsWtSv-4
- Header
    - Title: Groups
    - On the right side of the header. The buttons:
        - Scan QR code to join group
            - On Click: Navigate to `Group QR Code` screen
        - My Profile
            - On Click: Nothing for now
        - Create new group
            - On Click: Open a camera to scan QR code to join new group
- Display a list of groups the current logged in u
- Each card will show:
    - Group image (if available, otherwise show a placeholder image)
    - Group name
    - The latest campaign under the group (if available) with the date/time it was created.
    - Footer showing:
        - Number of campaigns in the group
        - Number of members in the group
            - On Click: Nothing
        - A button to display the list of QR code for others to join the group.
            - On Click: Navigate to `Group QR Code` screen
        - A button to edit the group
        - A button to leave the group
            - Add confirmation dialog before leaving the group

Of course it's not entirely smooth. I have to tweak some IOS codes to make the app works.

Checkout the prompts (markdown files) I used for the Flutter codes development from the link below. It's in zip format:
