Glean vs Langdock

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

Langdock

Langdock sells the thing European enterprises actually need before they can roll out AI: one assistant across the company, hosted in the EU, with admin controls, audit and no single-model lock-in. The customer list (Merck, BASF, Der Spiegel) and the compliance certifications back that up. The pricing is where to look closely — the EUR 25 seat is only the base, and workflows, governance and API tokens are three separate meters on top.

Pros

• +Model-agnostic, so the underlying provider can change without a migration
• +EU hosting with ISO 27001, SOC 2 Type II and GDPR compliance
• +Cloud or on-premise deployment, plus custom branding
• +Chat, agents, workflows, integrations and API in one platform
• +Web, iOS and Android clients, and a 7-day trial with no card

Cons

• −Four separate meters: seats, workflow runs, governance and API tokens
• −The workflow add-on starts at EUR 539/month, far above the seat price
• −Governance is free only until January 2027, then EUR 3.50 per user per month
• −Priced in euros, so the dollar cost moves with the exchange rate
• −Enterprise pricing above 1,000 users requires a sales conversation
