Senior engineering for regulated enterprises
Ship AI, cloud, and software that survives audit.
We build, modernise, and run the systems that banks, insurers, and health platforms can't afford to break. Senior-only teams. Outcome-anchored. Audit-ready by design.
Delivery experience inFCAPRAHIPAAGxP
Regulated environments we build and evidence within. Frameworks our clients operate under, not accreditations we hold.
Where we build
Engineering practices, one accountable team, shipped together, every time.
We don't sub-contract between disciplines. The architect on your kickoff call is the engineer in your retro. The compliance posture ships with the code.

Packaged solutions
Patterns we have shipped enough times to deliver fast.
Where the problem is well-known, the architecture should be too. These are the cross-cutting builds we have delivered inside FCA-, BaFin-, and HIPAA-regulated estates.
The Difference We Bring
Drive innovation with a partner that understands your business goals.
Team up with a senior team that gets the business side. We pair strategic insight with deep technical depth. Our engineers each bring 9+ years of hands-on experience across regulated estates, so you ship polished, audit-ready products while the window of opportunity is wide open.

Common questions
What engineering leaders ask before we start.
How we price
You know the model before you book the call.
Two ways to engage, both agreed before work starts. No day-rate drip, no discovery invoice, no line items you find out about later.
Fixed-price programmes
Scope, milestones, and cost agreed up front. You approve the number before the first sprint starts.
Dedicated-team retainers
A named senior team at a flat monthly rate. The same engineers stay through to handover.
Change orders are documents
Any change to scope is a one-page document you approve before we proceed, never an invoice you discover afterwards.
Next step
Get a senior architect on the call, first time, every time.
No SDR gauntlet. 30 minutes with an engineer who can scope the problem, name the risks, and give you an honest feasibility call.
