Harriet

Harriet is the independent alternative to Claude Enterprise for companies that have outgrown Claude Team or ChatGPT Business and do not want to commit the whole company to one vendor's Enterprise plan.

Every employee gets access to the leading AI models, including Anthropic Claude, OpenAI ChatGPT and Google Gemini or open weight models, under one company policy, with spend controlled per team and data hosted in the EU or US.

This app brings Harriet into Microsoft Teams. Employees ask questions in plain language and get answers drawn from your company's own documents, policies and procedures, with the source cited. When a question needs a person, it hands over to your team. It works for IT, finance, operations, sales and every other team, with no commands to learn.

*What IT and finance get:*

💷 *AI cost control:* one view of AI spend across every provider, broken down by team, with hard budget caps per team and per user.

🌍 *Data residency:* OpenAI and Anthropic models hosted in the EU, so your data stays in the region you choose.

🔒 *Audit and compliance:* an audit log of AI activity, single sign-on through your identity provider, and SOC 2 Type II certification.

🔁 *Model choice:* switch models or providers without renegotiating a contract, and keep your existing Claude or OpenAI accounts.

*What employees get:*

💬 *Answers in Teams:* company knowledge, cited, in the chat they already use.

🧠 *Shared skills:* when someone gets AI to do a task well, the whole team can reuse it after review.
