Technology signals change as companies adopt and drop tools, so treat this as a starting point. Check any single company with the free [tech stack lookup](https://enrich.chat/tools/tech-stack-lookup/).

## How is Microsoft 365 usage detected?

Technographic data comes from what a company exposes in public: code and tags on its websites, the HTTP headers its servers send, and DNS records such as MX and SPF entries that name email and SaaS providers. A detected signal shows the technology was in use when it was seen. It does not show how widely a company uses it, or whether every team does. Our [guide to firmographic and technographic data](https://enrich.chat/blog/firmographic-data/) explains the difference between the two.

## How do you sell to companies that use Microsoft 365?

A company's stack tells you what it already pays for. Three common plays:

- **Integration fit.** If your product connects to Microsoft 365, these accounts can use it on day one. Lead with the integration.
- **Competitive replacement.** If you sell an alternative to Microsoft 365, these are the accounts to win. Time outreach to renewal season and lead with switching costs.
- **Relevant personalization.** Mention the tool by name only when it changes your message, such as a workflow you improve inside Microsoft 365.

The people to contact are usually IT and workplace technology leaders.

## How do you find the right contacts at these companies?

Pick an account, then ask your AI agent for the people who own email and productivity there. Enrich.chat finds people by company and title and returns verified work emails, so you can build an account list in one prompt.
