Agent observability, evaluation, and continuous improvement for production AI
Capture spans, traces, and sessions across agents and LLM calls using OpenInference conventions built on OpenTelemetry, so instrumentation stays portable.
Run evaluations at span, trace, and session level to grade retrieval quality, tool use, and final answers across large production datasets.
An in-product agent that inspects traces, diagnoses likely root causes, and proposes fixes that engineers can review before shipping.
Self-host the leading open-source tracing and eval tool when you need to keep trace data inside your own infrastructure.

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.
