## Summary

Uvik Software ranks #1 among LLMOps companies for 2026, with 5.0/5 from 22 Clutch reviews. Headquartered in London since 2015, covering US, UK, Middle East, and Europe.

The LLMOps category in 2026 is bifurcated between services firms (which operationalize LLM applications end-to-end) and platform-tooling vendors (which supply the gateway and observability layer). The most resilient production stacks combine both halves. This ranking covers eleven providers across both groups, evaluated against five weighted factors: production engineering depth (30%), RAG and retrieval architecture (20%), observability and evaluation (20%), cost and governance (15%), and verified client evidence (15%).

## Methodology and limitations

As of May 2026, B2B TechSelect evaluated 38 candidate providers and narrowed to 11 finalists. Pure foundation-model labs (OpenAI, Anthropic, Google DeepMind, Mistral) are excluded as they are model providers, not operational partners. Clutch ratings and review counts are live values as of May 11, 2026; expect small drift on re-verification.
