Prototyping with AI
is easy.Building for scale
is still hard.You're going to need
human help.

If your growth didn't speed up when the tools did, you're not alone.

We work with founders who need to build strong foundations, then scale at pace. We're a duo of senior builder-strategists who deeply understand both modes.

We embed long-term as your bulletproof technical experts, sure—but that's not all. We're also your thought partners, sounding boards, product growth advisors and “founder support” at your fingertips—and we stay accountable to outcomes, not hours.

From zero to exit,
multiple times over.

We're remote (and seamlessly asynchronous) day-to-day, but we uphold that remote isn't always the best way forward. Nailing the details during kick-offs, pivots and key launches means coming to you, whether you're in the UK, EU or USA. We believe there's still no substitute for spending time together in the same room.

FAQ

Decades of combined experience, deep focus, and a genuinely AI-native workflow—multi-agent toolchains that let two senior people move at a pace that used to require a full dev shop. Leverage beats headcount, every time.

It's yours. 100%. All code, all intellectual property, all account credentials. No lock-in of any kind. When we part ways, you keep everything we've built together.

We typically onboard within a couple of in-person days. We'll dig into your product, your stack, and your goals, then hit the ground running. The ramp-up time is counted in hours, not weeks.

Absolutely. Our Explore & Validate engagement is designed for exactly this—a focused, low-commitment way to test an idea with real data before going deeper.

Yes. We're remote day-to-day, but we travel to you and kick off every engagement face-to-human-face. Major milestones happen in the same room, because that's how trust and momentum happen.
