What we do

Small senior team, end to end ownership: product, code and infrastructure.

Mobile apps

iOS and Android apps, with the backend and APIs behind them. From first prototype to App Store release.

AI-powered products

Practical AI features built on the model that fits the problem, from recognition and search to content generation. Designed to be reliable, grounded in your own data, and not tied to a single AI provider.

Sensor and motion data

Apps that work with sensors: accelerometer and gyroscope data from phones and wearables, including Apple Watch, and Bluetooth Low Energy connections to external devices such as heart rate straps and pedometers. Capture, signal processing and turning raw readings into metrics people can act on, in sport, health or any domain where sensor data matters.

Data platforms and governance

Data architecture and engineering at scale: pipelines, data warehouses and the governance that turns raw data into business-ready information.

Industry expertise

Two decades of experience in advertising, retail and telecom: from retail data migrations and telecom platforms to advertising integrations and operations.

Product and infrastructure

We take an idea to production, run it in the cloud or on dedicated servers, and keep infrastructure costs under control.
