How to choose
Four steps to a decision you can defend.
The method we use in an AI readiness assessment, before any contract is signed.
- 01Map where the work happens
List the teams, the tools they live in and the tasks AI should help with.
Week 1 - 02Agree criteria and weights
IT, security and the business sign off what matters most, before any demo.
Week 1 - 03Pilot two platforms
15 to 25 people per platform, the same real tasks, measures agreed in advance.
4 to 6 weeks - 04Decide in writing
A short decision memo: results, costs at your size, risks and the rollout plan.
Week 6 to 8
The pilot is the step that settles most decisions: the same tasks on both platforms show more than any feature list.
FAQ
Comparing enterprise AI platforms
What is the best enterprise AI platform?
There is no single best platform. The right one depends on where your work happens, the admin and data controls you need and the price at your size. Microsoft 365 Copilot fits Microsoft-centred companies, Gemini Enterprise fits Google Workspace and Google Cloud, and Claude and ChatGPT work across any stack.
Can a company use more than one AI platform?
Yes. A common setup is one platform for everyone and a second one for teams with specific needs, such as engineering or legal. Claude models are also available inside Microsoft 365 Copilot and Gemini Enterprise, so model choice does not always mean a second platform.
Which platforms train on our data?
None of the four by default on their business and enterprise plans: Anthropic, Microsoft, Google and OpenAI all state that business data is not used to train their models by default.
How much do enterprise AI platforms cost?
List prices for the enterprise tiers that publish one range from $20 to $30 per user per month: Claude Enterprise is $20 per seat plus usage, Microsoft 365 Copilot is $30 on top of a Microsoft 365 plan and Gemini Enterprise Standard and Plus start at $30. ChatGPT Enterprise is priced by OpenAI’s sales team.
How long does a platform decision take?
Six to eight weeks with a pilot: one week to map the work and agree the criteria, four to six weeks of pilot on two platforms, then a written decision. Our AI readiness assessment covers the first part in about two weeks.
