You have an idea, maybe even people waiting to use it, and nobody to build it. Hiring an agency is expensive, and learning to code from scratch takes time you would rather spend on customers. So you want a technical cofounder: someone who builds the product and owns it with you.
Developers get pitched ideas all the time. Here is how to be the one they say yes to.
Show what you have already done
An idea on its own is cheap. What makes a developer take you seriously is proof that you can do your half of the work. Before you go looking, try to have at least one of these:
- Conversations with ten or more people who have the problem, and notes on what they said.
- A waitlist, a pre-order, or one customer who says they would pay.
- Rough sketches of the main screens, even on paper.
- A plan for how the first hundred users will hear about it.
You are not asking someone to build your dream. You are inviting them into a company that already has momentum.
Write a post that answers their questions
A good “looking for a technical cofounder” post saves everyone time. It says who the product is for, what you have done so far, what needs building first, what you offer, how much time you expect, and where you are. For example:
Building: an app that helps small gyms fill empty class spots. Done so far: 14 gym owners interviewed, 3 ready to try it. Need: a technical cofounder to build the first version (web and mobile). Offer: equity, split fairly and earned over time. No salary yet. Time: about 15 hours a week to start. Where: Dubai, remote is fine.
Be specific about the offer. “Equity” with no idea of how much, or how it is earned, puts people off.
Look where developers already are
- People you already know. Classmates, old colleagues and friends of friends are the warmest place to start, because trust is already there.
- University computer science clubs and hackathons. Students and recent graduates often want something real to build.
- Online communities. Build-in-public circles on X, Indie Hackers, and Y Combinator’s Co-Founder Matching are full of builders looking for their next project.
- Local meetups. Tech and startup events in your city, where you can meet people in person.
- Sapnora. Post your idea and write that you need a developer. Developers who like it ask to join, and you choose who to talk to. It is free.
Reach out like a person
Keep the first message short and about them: what caught your eye in their work, one line on the idea, and one small ask, such as a twenty-minute call. “I have a huge idea, you build it for equity” is the message almost everyone ignores.
Work together before you split anything
Liking each other on a call is not the same as building together. Pick a small project you can finish in a few weeks, like a clickable prototype or a landing page with a sign-up form, and see how it goes.
Talk about the hard things early: how many hours each of you can give, who decides what, what happens if one of you leaves, and whether either of you needs a salary soon. Many startups give founders their shares over time, often four years with a one-year “cliff”, so nobody keeps a big share after leaving early. Write down what you agree, and have a lawyer look at it before it becomes official.
Red flags
- They want a large share up front, before any work together.
- They will not talk about time, money or what happens if things go wrong.
- You disagree about what you are building and for whom.
- Either of you wants the other to do all the work.

If you are past the idea stage and need your first engineer rather than a cofounder, read how to hire your first engineer. On Sapnora you can post the role, and developers who like what you are building ask to join.
