Fly is an exciting bootstrapped startup based in Berlin, operating in the AI Sales-SaaS space. We're at the early stages of our journey, focusing on sustainable growth rather than chasing rapid, unsustainable scaling. Our goal is to build a highly profitable company with long-term potential, where each team member has full autonomy and can shape the future of the business.

We're looking for a Technical Co-Founder to join our founding team. This is a unique opportunity to partner with us in building a company from the ground up. As we’re currently bootstrapped, this will initially be a side project, with no salary available at the outset. However, the right person will see the long-term potential and be driven by the prospect of professional and financial independence.

So if you have an Indie Hacker Mindset, this is the right job for you
