About Us

We have been on the inside. Now We Build It Better.

Our team has a combined 30 years of experience at leading financial institutions like Citi, BNP Paribas, Shopify, and Klarna, building, shipping, and navigating the systems that power the modern finance industry. We launched We Build Products to introduce a better way of delivering compliance technology to banks and fintechs.

Why we started

We saw how it works on the inside. We knew it could be better.

Between us, we have spent over 30 years at places like Citi, BNP Paribas, Akbank, Shopify, and Klarna. We have seen how platforms really get built at these companies. Some of it was great. A lot of it was not.

We watched vendors sell bloated systems that looked good in procurement but fell apart in production. We sat through 18-month projects that shipped the wrong thing. We saw compliance teams scrambling to patch platforms that nobody designed with regulators in mind.

And at these bigger companies, we both hit the same wall. You can see exactly what needs to be built. You know how to solve the problem. But the org chart, the vendor contracts, the politics will not let you move. You never get to bring everything you have to the table.

How we work differently

No long sales cycles. No generic proposals. Just focused work that gets you to a decision fast.

We start with a sprint, not a slideshow

We start with a sprint, not a slideshow

Every engagement begins with a 4-week Discovery Sprint. You get a blueprint, a prototype where it makes sense, and a clear roadmap. If it does not work for you, you walk away with everything we built. No lock-in.

We build with the audit in mind

We build with the audit in mind

Compliance is not something we bolt on at the end. We have sat across from regulators. We know what BaFin looks for, how DORA changes the game, and where platforms break under scrutiny. We build for that from day one.

Small team, full stack, no handoffs

We do not hand you a report and disappear. The people who run your Discovery Sprint are the same people who build your platform. One team, start to finish.
