Is this you?

Are you sitting on a product idea, a Figma mockup or something hacked together in an AI tool, and not sure what to do with it next?

Maybe one of these sounds familiar:

  • "I need something real to show customers or a funding panel, but I can't commission a full build before I've validated the idea."
  • "I've built something in an AI tool but I don't know if I can trust it, or what to do with it next."
  • "I don't know what to build versus what to buy, and I'm worried about making a decision I'll regret."
  • "Tech is eating my time and headspace when I should be focused on the mission."

If any of those sound familiar, the Proof Sprint is designed for exactly this moment.

What you get

  • A working, usable prototype you can put in front of real users to start gathering real feedback and validation.
  • The benefit of a team that already understands circular business models; you don't have to explain the context, and we bring our own circular economy expertise to complement yours.
  • A clear, honest view of your technical options for what to build next, including build versus buy recommendations.
  • A credible technical narrative for grant panels or early investors.
  • Confidence that the foundations are sound on security, privacy and scalability.

How it works

  1. Book a free 30-minute discovery call. We'll understand your idea, your goals and your timeline, and tell you honestly whether this is the right fit.
  2. We align on what the prototype needs to prove and to whom, and agree on the scope.
  3. We build iteratively, with you involved throughout. Delivery in 2 to 4 weeks.
  4. You receive the working prototype plus written guidance on your technical options for what comes next.
  5. If it makes sense to continue working together, we can discuss next steps; but there's no assumption or obligation either way.
