Glean
$300M ARR in 15 months and the only enterprise platform shipping both MCP and A2A — but nobody publishes a price, buyers report six figures past 500 seats, and the same connector breadth that makes it powerful is, per independent security researchers, an exfiltration channel standard DLP can't see.
| Glean Enterprise (legacy seats) | ~$50–75/user/mo (buyer-reported) | 100-seat minimum, ~$60K minimum ACV, ~10% support fee — not officially published |
| Glean Enterprise Flex | Usage-based FlexCredits | Per-action credit costs are published officially; USD value per credit is not. Independent estimate ~$0.25–0.50/credit |
| Enterprise | Custom | Contact sales |
No official numeric pricing is published anywhere. All buyer-reported figures are third-party estimates (G2, Vendr-sourced), not vendor-confirmed. EUR figures above are approximate conversions at the 29/07/2026 EUR/USD rate (~$1 = €0.88), not vendor pricing.

Strengths
Permission-aware retrieval across 250+ connected apps is real and independently confirmed: Forrester measured 141% ROI over three years, G2 rates it 4.7/5 across 162 reviews. The agent stack backs that up with a documented evaluation framework (golden test sets across four failure categories) and it's one of very few platforms shipping both MCP and A2A at once. Revenue is real too: $300M ARR, up from $100M fifteen months earlier, with Fortune 500 customer count nearly doubling year over year.
Honest dings
Pricing is opaque everywhere: no public rate card, and buyer-reported figures from G2 and Vendr put six-figure annual contracts within reach once you pass roughly 500 employees, plus a support fee on top. Independent security researchers flag a specific, non-generic risk: the same breadth that makes Glean useful, synthesizing answers across 100+ systems in one chat reply, is also a data-exfiltration channel conventional DLP tooling never sees, because the leak is a sentence, not a file. A separate audit of the new Protect+ safety tier found real new controls but also some repackaged upsells, and confirmed no FedRAMP High authorization yet.
