If ChatGPT Enterprise isn’t quite right — usually because it’s single-vendor, per-seat, or US-default — there are strong UK-relevant alternatives. Here’s a fair 2026 roundup. (dgm implements osFoundry as an independent partner; we’ll be honest about where each option fits, including ours.)
Why look elsewhere?
ChatGPT Enterprise is excellent, but three things send UK businesses looking:
- single-vendor — OpenAI models only, no switching;
- per-seat pricing — scales with headcount; and
- data residency — you may want stronger UK/EU control or self-hosting.
(See our osFoundry vs ChatGPT Enterprise deep-dive.)
The main alternatives
| Alternative | Best for |
|---|---|
| Claude for Enterprise | A polished single-vendor (Anthropic) chat |
| Microsoft 365 Copilot | Microsoft-centric organisations |
| Google Gemini Enterprise | Google Cloud/Workspace organisations |
| Glean | Enterprise search across many tools |
| Perplexity Enterprise | Research and answers |
| osFoundry | Model-agnostic, usage-priced, self-hostable platform |
Matching to priorities
- Want model flexibility? → model-agnostic options: osFoundry, Dust, Relevance AI.
- Want a polished single-vendor chat? → Claude for Enterprise or Copilot.
- Want UK/EU data residency / self-hosting? → osFoundry (self-host or EU region), Mistral (European), n8n.
- Want enterprise search? → Glean.
- Want research? → Perplexity Enterprise.
Where osFoundry fits
For businesses wanting more than chat — model flexibility (bring-your-own-key, including OpenAI), usage pricing with no per-seat fees, consolidation of tooling, and self-hosting for UK data control — osFoundry is a fit. It’s a platform, not just a chat product, so it suits those wanting to consolidate and orchestrate. For straight single-vendor chat, Claude or Copilot may suit better — we’d say so.
How to choose
Decide your priorities (model flexibility, data residency, pricing, ecosystem, scope), shortlist accordingly, and run a small pilot before committing. (See how to evaluate AI vendors.)
