Hephaestus helps startups and businesses turn ideas into products people pay for. We test the idea, build the software or hardware, launch it and stay on to help it grow.

We take ideas all the way to market.

Some founders arrive with a rough idea, others with a product that has stalled. We pick it up from there and stay through validation, build, launch and growth.

Our approach

Most agencies hand over the code and move on. We stay, and work on your business the way a co-founder would. We pair AI with decades of software and market experience to give your product the best possible chance of success.

  • Speed

    Less time between the idea and the first customer.

  • AI-powered execution

    Experienced people make the calls. AI speeds up the routine work.

  • Flexibility

    Engagements shaped around your stage and your runway.

  • Shared success

    We measure our work by your results, not our hours.

An agency bills you.
A partner backs you.

Outsourcing firms get paid the same whether your product flies or flops. We’d rather have something riding on it.

Decades of experience, with modern tools.

Our people have spent decades building software and taking products to market. AI speeds up the routine parts of that work; experience decides what to build, who to sell it to and when to change course.
