"Should I make people sign an NDA before I tell them my idea?" is the most common first-time founder question and the most reliably wrong one. Nobody is going to steal your idea. The opposite is the actual problem: you're going to fail because not enough people know about it.
Why nobody steals ideas
- Everyone with the skill to execute it already has 10 of their own.
- The idea is 5% of the work. Execution and distribution are 95%.
- Even if someone hears it, they don't have your domain context.
- The market is rarely winner-take-all at the size you're operating in.
The asymmetry
Sharing your idea has a tiny chance of someone copying it and a huge chance of someone introducing you to a customer, a co-founder, or a critical insight. The expected value of sharing is enormously positive.
What an NDA actually does
It signals to the other person that you're inexperienced and they should stop taking the meeting seriously. Real investors, advisors, and senior operators won't sign one and will quietly downgrade you. There is no upside.
The real risk
The real risk is invisibility. Read how to get the first 100 users — every step requires telling lots of people the idea, including direct competitors. That's a feature.
What to do instead of protecting
- Tell 50 target users in detail this month.
- Post about it publicly if your audience lives where you can find them.
- Ask for honest feedback, including "why this won't work."
- Use feedback to either sharpen or kill the idea fast.
The exception: a defensible patent in biotech, hardware, or genuinely novel ML research. That's not what you're building.
