Would you join a startup before it's funded? Why or why not?

I'm building Axisure, a platform where people can find others to build startup products with.

One thing I've noticed is that many founders have ideas but can't find the right people to help bring them to life. At the same time, many developers, designers, and marketers want to work on interesting projects but aren't sure which ones are worth their time.

I'm curious:

Have you ever joined an early-stage startup before it had funding?

What made you say yes?

If you said no, what was missing?

For me, trust seems to be one of the biggest challenges. People need to believe in the idea, the team, and the likelihood that something meaningful will come from their effort.

I'd love to hear what factors matter most when deciding whether to join a startup at its earliest stage.
