What our research says

Glean

Glean is the reference implementation of permission-aware enterprise search, and permissions are the hard part everyone else underestimates. It is also priced so that only companies with a real sprawl problem can justify it.

Pros

  • Permission inheritance from each connected system is done properly, not approximated
  • Answers cite and link the underlying documents rather than paraphrasing them away
  • Connector coverage across the mainstream SaaS estate is broad
  • Commercially solid: about $300M ARR by May 2026 at a $7.2B valuation

Cons

  • No published price anywhere, and contracts start in six figures
  • Value depends entirely on connector coverage of your specific stack
  • Index quality inherits whatever mess exists in the source systems
  • Overlaps increasingly with Microsoft and Google's bundled offerings, which cost nothing extra

Stilla

Delegating by @-mention in the tool you are already in removes the main reason agent products go unused, and the credit generosity at the free tier lets you find out whether it works on your real backlog. Pricing per organisation rather than per seat is unusually sane. The weak spot is that nothing on the site names the company or its jurisdiction.

Pros

  • Delegation by @-mention across Slack, Teams, GitHub, Linear and email
  • Roughly 3,000 tool integrations plus MCP support for adding your own
  • Priced per organisation at $40 a month rather than per seat
  • SOC 2 Type II and GDPR posture with a public trust portal

Cons

  • No company name, address or country published anywhere on the site
  • Usage is metered in credits, so heavy months cost more than the headline plan
  • Several legal pages return 404 from the footer links

Which one fits

Choose Glean if you need

  • Organisations above roughly 500 people whose knowledge is scattered across a dozen SaaS tools

Choose Stilla if you need

  • Teams that live in Slack or Teams and will not open another dashboard
  • Product and operations people drowning in status updates and ticket admin
  • Organisations that want one agent reaching many tools rather than one agent per tool
