Glean vs Sensay

Two fact sheets from our own research, side by side — pricing, platforms, API access and status re-checked by us rather than quoted from the vendors. Sensay publishes a starting price ($500); Glean does not. Only Glean ships a public API.

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

Sensay

Sensay attacks a real and badly served problem: the tacit knowledge that walks out with a resignation. Voice interviews rather than a document template is the right instinct, because the useful material is what nobody wrote down. The numbers on the site are vendor claims, and pricing per knowledge base gets expensive during a wave of departures.

Pros

  • Adaptive voice interviews rather than a static exit form
  • Output is a queryable chatbot, not just a transcript
  • Slack and Teams access for the receiving team
  • A single published price with no quote gate

Cons

  • $500 per knowledge base per year scales badly with headcount
  • Retention and onboarding metrics are unverified vendor claims
  • No free tier or trial listed on the pricing page
