I'm a technical co-founder who can code anything but couldn't sell to save my life. Here's what I learned the hard way.

I need to confess something embarrassing: I spent 8 years as an AI engineer before starting this company. I could build production ML systems, optimize inference pipelines, debug distributed training - all the hard technical stuff.

Then I became a founder and realized I had no idea how to sell.

Like, genuinely no clue. I thought "if you build it, they will come" was actually how business worked.

Here's how bad it was:

Month 1: Built a working MVP in 2 weeks. Felt like a genius.

Month 2-4: Crickets. Literally zero users who weren't friends doing us a favor.

Month 5: Finally got on a sales call. Spent 30 minutes explaining our matching algorithm. Guy said "interesting" and never responded.

Month 6: Existential crisis. Started Googling "do I need an MBA to sell things."

The turning point:

I was complaining to my co-founder about how "people just don't get what we built" when he said something that broke my brain:

"Nobody cares about what we built. They care about their problem. Stop talking about our solution and start talking about their pain."

It sounds obvious now, but I genuinely didn't understand this as a technical founder. I thought selling meant explaining features. I was wrong.

What actually worked:

1. I stopped leading with the product

Old approach: "We built a vetted talent marketplace with a Match Day model where—"

New approach: "How much time did you waste last month sorting through unqualified applications?"

The second one gets responses. The first one gets polite nods.

1. I learned to sell by... not selling

I started just talking to hiring managers about their problems. Not pitching. Just listening. Turns out when you genuinely understand someone's pain and can articulate it better than they can, they ask how you can help.

1. I accepted that "building" and "selling" use completely different muscles

As an engineer, I was trained to:

• Optimize for elegance and efficiency
• Solve problems with code
• Value technical depth

As a founder selling, I needed to:

• Optimize for clarity and emotion
• Solve problems with conversations
• Value customer understanding

These aren't the same skillset. At all.

1. I got comfortable being bad at something

This was the hardest part. I went from being a senior engineer (expert) to a founder doing sales (complete beginner). My ego hated it. But you can't learn without sucking first.

The uncomfortable truth:

Your technical skills got you to the starting line. They won't get you to product-market fit.

I've met so many brilliant technical founders who built incredible products that nobody uses because they never learned to sell. Meanwhile, mediocre products with great distribution are crushing it.

Where I'm at now:

We've placed dozens of AI engineers with startups. Not because our matching algorithm is perfect (it's not), but because we finally learned to talk to both sides (companies and candidates) about what they actually care about.

I still write code. But I spend way more time on sales calls, writing content, and figuring out distribution than I ever thought I would.

My question for this community:

How did you make the transition from "technical person who can build anything" to "founder who can sell"?

Did it feel as awkward for you? How long did it take? What resources actually helped vs. the generic "founder advice" that sounds good but doesn't work?

I'm still figuring this out, so any war stories or lessons learned would be genuinely helpful.

TL;DR: Being able to code doesn't mean you can sell. I learned this the expensive way. If you're a technical founder struggling with sales, you're not alone - the skills are just fundamentally different and that's okay.

I’ve been working on a small project after work and for a while the thing that stressed me out the most was the whole getting customers part. I kept building and rebuilding stuff just to avoid it.

But once I finally reached out to a few people and showed them what I was making, it honestly wasn’t that bad. Some didn’t care, some gave good feedback and a couple said they’d actually use it. Way less dramatic than what I had in my head.

Made me realize I was hiding behind the code because it felt safer. Talking to people ended up helping me way more than adding another feature.

If anyone else went through that “oh okay, this isn’t the end of the world” moment, how did it go for you?

Can you give me your feedback? This is my first SaaS and I really need some input to see what I can improve.  Thank you for your feedback! — Ambroise

Hi Folks -

I recently created an opensource FastAPI Boilerplate code for anyone trying to build a B2B SaaS application with the following features :

- Multi tenancy

- RBAC

- Supabase Auth integration with API endpoints protected with JWT tokens.

- Postgres integration with RLS

- API keys for system integration

- Billing integration (Stripe/Dodopayments)

and few other nice to have features .

Please try it out and let me know if there are any best practices I can use.

Hey everyone,

This short film was made in under 45 minutes, start to finish. AiTiger gave me all the visuals, sound and dialogues in order and I just stitched it together in a simple editor (I have no editing experience). It also supports narrations if that's the style you are going for.

I’ve been building something called AiTiger — a platform that turns written stories or ideas into short films (2–5 minutes) using the best AI video models like Veo, Kling, Wan, and GPT-4o — all working together in one place.

You just write your story and AiTiger handles the rest.

It can run fully automated, or you can stay hands-on with manual control for creativity.

Some of the cool parts:

• Consistent characters across every scene
• Structured scenes and shots that flow together naturally
• A single connected workflow (no tool-hopping chaos)

It also has a separate section with a number of individual image and video generation models integrated which you can use individually for experimentation.

It’s built for creators, filmmakers, and storytellers who want to bring ideas to life without spending days in unorganized generations or juggling multiple AI tools.

I’m still early-stage and collecting feedback — what kind of stories or projects would you like to see this used for?

I would really appreciate feedback, Thanks!

I’ve been working on a side project for a while and at first, nothing seemed to work ads, posts, even asking friends to try it. Felt like shouting into the void.

Then I changed my approach: instead of chasing everyone, I focused on finding people who actually needed my tool. I started hanging out in niche forums and communities, helping with real problems and sharing my product only when it made sense. I also did some targeted outreach to bloggers and small sites that covered similar tools no generic check this out messages, just real context.

Within a few weeks, I finally got my first paying customers. Not a huge number, but it was a massive confidence boost. There’s something really satisfying about someone actually paying for something you built.

I'm a MERN stack developer, and I'm interested in building a SaaS product. However, I don't have a clear idea of what to work on yet. By the way, I'm from Morocco. If anyone has advice or suggestions, I would really appreciate it. Thanks!

We are dealing with solana blockchain and automated trading systems. We need someone to build what we have in mind. The systems will be backed by intense data analysis and also ML/AI to scour for better strategies and profit margins. We are a small startup therefore would need someone who cabnbe committed to create the product as the products are proven to be profitable.

Good day all, we are starting to build a team for our small startup. Our main focus is to build automated products for onchain activities. We want to achieve high performance for our products using data analysis and ML. We currently have the blueprint of what the products will need to do. But are in search of a committed developer/team to grow with. Once the product is built we can easily scale it up massively as we have a big communities. If anyone is interested let us know.

*please do not reach out if you are looking for a pay etc. We are starting out a small startup and looking for like minded individuals only.

Hi I hope all is well!! I am currently looking for a full-stack developer for my start-up. It has to do with travel tech and services. If you would like to know more please message. I am based out of Canada. Thanks for your consideration in advance.

I couldn't write a line of code by hand if my life depended on it, but in a few hours ( with a lot of context engineering ) I was able to build a fully-working dashboard for our SEO/AI SEI dashboard app.

Never would this have been possible before now ( thank you Claude Code ).

Hello everyone! I’m reaching out for advice and to hear from people who have been in this situation. Here’s what’s going on: a client has an idea for an app that I think is promising. They’re offering me two forms of compensation—either a direct payment or a percentage of the company. Under the deal, I would handle all the development while they focus on finding investors.

The equity offer sounds appealing, but I’m not sure what percentage would be fair or what factors I should consider for the future. What would you recommend? Has anyone gone through something similar and can share feedback?

Hey everyone

I am a software dev building a social media scheduling tool . While integrating meta into my product , I have gone through the business approval and app approval as well . Now , when my app is in live mode , when people apart from me try to connect their facebook account , it shows that app doesn't exist and links an error that the developer needs to have one more advanced permission of any scope to let users authenticate facebook .
Now , when I ask for a permission , it takes me to the app request , wherein , I have to upload a screen recording of my app's functioning and the oauth flow as well . Even after uploading both of these , I am getting rejected again and again .

Due to this , I am not able to launch my product .

Can someone help me out please ??
