We always leave things better than we found them.
We start with the end in mind.

If you build it, you fix it.
We trust each other and ask for help.

About Us

We’re a well-funded, early-stage London-based startup on a mission to revolutionize compliance for banks and fintechs with cutting-edge, AI-powered regtech solutions. We’re building a product and engineering team to drive the platform in an agile way, using AI and ML at its core, enabled by microservice running in AWS. We aim for full CI/CD, deploying as soon as tests are green.

We value clarity, transparency, and craftsmanship in everything we do. We believe that speed comes from doing things right, and we encourage creative use of AI, not just in our products, but in every aspect of how we work.

Our London office is a hub for collaboration, and we embrace flexibility and remote work for most days. If you are not in London, or not even the UK, we will make that work too.

Competitive compensation tailored to senior talent.
Flexible working arrangements (hybrid London or remote).
End-to-end ownership of impactful, open-ended challenges.
Significant influence over technical and product direction.
Supportive, achievement-driven environment that values curiosity, ownership and clarity.
