What each is best for
Glean is worth it if… mid-market and enterprise companies (500+ employees) whose employees waste hours per week searching across siloed apps for information. Reported starting ~$40-50/user/mo for mid-market puts a 500-employee deployment at $250-300K/year.
Microsoft 365 is worth it if… Microsoft 365 Business is worth it for teams that need full Office desktop apps (Word, Excel, PowerPoint, Outlook) + email + Teams + SharePoint + OneDrive — particularly if you have Windows-heavy workforce or compliance requirements.
