Embedded AI-native engineering pods with measured delivery uplift
Engineers join your standups, repositories and Slack channels as teammates, working inside your conventions rather than as an external vendor squad.
Agentic systems are developed from data foundation and pilot through to production, built around your existing platform instead of a greenfield rewrite.
Structured enablement for engineering, technical leadership and delivery teams so AI-native practice remains in-house after the engagement ends.
A developer-intelligence layer links version control, issue tracking and AI usage into a single weekly read on cycle time, review load and AI assist hours.

Independent AI, ML and data science research & engineering consultancy
Bespoke algorithms and models built for problems that generic tools cannot solve, from computer vision to recommendation systems.
A structured ideation, prototype and integration process designed to de-risk research-heavy projects before full rollout.
Products including SemaReader for semantic reading and knowledge-graph creation, and SemaDB, a vector database for similarity search.
Hands-on data analysis, anomaly detection and predictive modelling engagements shaped around specific business goals.
