Expertise

Where we've earned our stripes

01

Real-time bidding & machine learning

Built and operated a demand-side platform with real-time bidders and machine-learning models making pricing decisions at auction speed.

02

Consumer IoT at national scale

Engineered the mobile and backend systems behind the UK's largest consumer IoT platform, serving over a million connected homes.

03

Fintech-grade reliability

We hold our own product, Fat Pitches, to brokerage-grade standards for security and correctness — the same discipline we bring to client work.

Our own product

Fat Pitches

Every buy order armed with 100% of your cash.

Standard resting orders lock your cash up front. Fat Pitches keeps your dry powder whole — staging up to 50 fully sized orders on the same balance and placing each one in your Charles Schwab account only when its entry price is actually reached. No margin. No magic. Just no premature commitment.

The brokerage-grade standards we hold our own product to are the ones we bring to every client.

About

A small, senior software house

No account managers, no bench of junior developers learning on your invoice — the people who scope the work are the people who write the code.

Two decades of production experience across the US, UK, Switzerland and the Netherlands taught us the same lesson every time: reliability is a design decision, not an afterthought. We've carried that discipline from real-time bidding systems and IoT platforms serving millions of households into Fat Pitches, our own fintech product, where correctness isn't optional.
