From idea to co-founder match platform in 8 days — Built solo. No code. Bolt.new

👋 Hey Product Hunt, I recently built something I wish existed 2 years ago.

YoFounder.com — a compatibility assessment platform for startup co-founders.

✅ Built solo

🧠 No code. @bolt.new instead

🗓️ In 8 days

🔥 Powered by Bolt hackathon

📦 160M tokens later — it’s live



🧩 Why this matters

Finding a co-founder is hard.

Finding one you’re actually compatible with — even harder.


YoFounder helps founders avoid painful mismatches by:

Asking the right 66 questions (based on First Round Capital's and Gloria Lin's framework)

Analyzing alignment and conflicts with AI

Showing both answers and tailored discussion prompts


✍️ How it works

1. You invite someone you’re considering

2. You both fill the assessment (in any language)

3. AI returns a report — strengths, risks, reflection questions

4. You both see each other’s answers

5. Talk it through. Make a smarter decision.


🧪 Public matchmaking coming soon

💬 For now, you can only match with those you invite

🌍 Any language — supported


I’d love feedback from early-stage founders, accelerators, angel groups — anyone helping teams form at day zero.

Try a match. Share how it went.

And huge thanks to Dasha Kroshkina for sharing the original “50 Questions” framework that inspired the whole thing 💜

I documented the entire marathon: the bugs, the breakthroughs, the burning tokens, and the sleepless nights.

The Bolt hackathon is still live — for 7 more days.

If I could build this, you can build yours too.

Register at yofounder.com, invite someone you know — or me!

Let’s test our compatibility 💜☺️
