We help teams build data platforms, systems and software that stay correct, fast and understandable as they grow. Our engineering practice was shaped by over a decade at high-growth startups and quantitative trading firms.
Pipelines and storage you can trust: well-modelled, observable and cheap to run.
Turning messy data into decisions, with the rigour of a trading desk.
Systems designed for correctness and performance, then built and shipped.
Senior judgement when you need it, without a full-time hire.
Decisions start from data. We find out where the real bottleneck or risk is before writing a line of code.
In trading, a subtle bug costs money in milliseconds. We bring that discipline: tests, invariants and reproducibility by default.
The best system is the one your team can understand, operate and change long after we've gone.
Startup speed with production standards: frequent, reversible changes that deliver value early.
We document, pair and hand over properly, so the knowledge stays with you.
Building products from the first commit, scaling systems and teams through growth, and making pragmatic trade-offs when time and money are tight.
We know how to move fast without leaving a mess for the next engineer.
Working on systems where performance, correctness and data quality are not optional, and where every decision is measured.
That rigour carries into every engagement, whatever the industry.
A short, fixed-scope review of your system, data or roadmap, ending in a clear written plan.
Hands-on delivery of a defined project, embedded with your team or working independently.
Ongoing senior support on a retainer: architecture, code review and technical direction.
Tell us what you're working on. We'll reply within a couple of working days with honest thoughts on whether, and how, we can help.
