The studio

The build has to survive scrutiny, not just a demo

Your buyers work in regulated markets. They will run a security review, ask who owns the data, and put the product in front of people who use software like this all day. We build for that conversation, because our return depends on you winning it.

Capabilities

What you get, and who owns it

One team from scope to production, and the whole output assigned to your company as it is written.

01

Regulated product delivery

Private banking, family office, alternative investments, longevity and employee wellbeing. We have shipped in all of them. We know what an information security review asks for before it asks.

02

Product design

Research with your actual buyers, then interfaces built for advisors, clinicians and private clients. These are people who work in the product all day and will not tolerate a demo that only looks good.

03

Engineering

Typed, tested, reviewed code with CI and observability from the first week. Built to survive a due diligence process, because yours will have one.

04

AI where it earns its place

We use AI to move faster through research, scaffolding and iteration. Every architectural decision and every line that reaches production is owned by a named senior engineer.

05

Continuous delivery

Shipping does not stop at launch. Our return depends on your revenue, so we keep building for as long as the partnership runs.

06

Go-to-market support

Positioning, pricing and launch systems. You own the selling. We make sure the product is not the reason a deal stalls.

On AI

We use it. We don't hide behind it.

AI moves us through research, scaffolding and iteration faster than a team could three years ago. That is why we can fund a build and still make the economics work — the speed is what makes the offer possible, not a headline in itself.

Every architectural decision and every line that reaches production is owned by a named senior engineer. In a market where your product will be audited, “the AI wrote it” is not an answer either of us can give.

If we get the estimate wrong and the build costs us more than we thought, that is our loss. You owe 2.5× the number you signed, not 2.5× what it took us.

And we only get paid if it sells.

No fee for any of the above. We take 6% of revenue once you reach $25K MRR, up to 2.5× the build value — and then we stop.
