We are looking for people with startup skills. It can be front-end, backend, marketing, bizdev, testing, etc.
The biggest problem with joining a startup without funding is that it can be a time-sink. The entrepreneur can have unrealistic expectations of unpaid work.
SB is different. We don't hold hackathons. We hold launchathons. No ideas thought up on Friday and launching on Sunday. The startups and entrepreneurs are vetted for weeks prior to development. The tools are setup and provided.
You just need to dig in and do what you do best. Deliver product. We also have room for people who just want to learn.
