What it is
Glean is the leading enterprise AI search and knowledge platform — a tool that searches across all the disparate systems an organisation uses (Slack, Google Workspace, Salesforce, Confluence, Jira, GitHub, Notion, and 100+ others) and provides AI-powered answers grounded in the organisation’s actual content.
Founded by ex-Google search engineers, Glean built what Google did for the web — comprehensive search and AI — but for the inside of organisations. As businesses accumulate vast amounts of information across many systems, Glean’s promise is making that information searchable and useful again.
For an Australian business with documents in:
- SharePoint
- Google Drive
- Slack conversations
- Confluence
- Salesforce
- Email archives
- Multiple ticketing systems
- Various wikis
Glean searches and analyses across all of them simultaneously, giving employees answers like: “What did we decide about the X project?” or “Who at the company knows about Y?”
What Glean does
Universal enterprise search
Search query → results from all your connected systems. Like Google for inside your company.
AI-powered Q&A
Ask natural language questions; Glean answers using your actual organisational content, citing sources.
Personalised
Glean knows what you have access to, what you’ve worked on, who you work with. Results are personalised.
Permissions-aware
Critically: Glean respects existing permissions. It only shows results you’re already authorised to see in source systems.
Knowledge graph
Glean builds an organisational knowledge graph — understanding people, projects, documents, and their relationships.
AI assistants and apps
Custom Glean Assistants for specific workflows; integrations into Slack and other tools.
Source integrations
100+ connectors including: Google Workspace, Microsoft 365, Slack, Confluence, Jira, Salesforce, Notion, GitHub, ServiceNow, Box, Dropbox, and many enterprise systems.
Who uses Glean
Glean’s customers include large and mid-market enterprises:
- Major tech companies
- Financial services firms
- Healthcare organisations
- Professional services firms
- Government and defence (with appropriate compliance)
In Australia: increasingly adopted by enterprise organisations. Specific customer details often confidential.
Why this matters
The problem Glean solves is universal in larger organisations: information fragmentation.
A typical employee’s day:
- Question about a project: where’s the answer? Slack? Confluence? Email? Asana?
- Need to find a similar past proposal: which Drive folder? Whose Dropbox?
- Want to understand context on a client: CRM, emails, meeting notes, contracts — all scattered
- Need to know what an expert in the company has worked on: directory + projects + comms scattered
This information fragmentation creates real productivity loss. Studies suggest knowledge workers spend up to 20% of time searching for information.
Glean’s value proposition: reclaim that time by making the search work.
How it works
Glean technical approach:
- Connectors integrate with source systems via APIs
- Indexing continuous content indexing while respecting permissions
- Knowledge graph built from content + organisational structure
- Retrieval when you search, finds relevant content
- Ranking personalised based on you and your team
- AI generation uses LLMs (various) to answer questions grounded in retrieved content
- Citations every answer links back to source
This is RAG (Retrieval-Augmented Generation — see rag) at enterprise scale with permission management.
How Glean compares to alternatives
| Tool | Approach | Best for |
|---|---|---|
| Glean | Pure enterprise AI search | Large orgs with many systems |
| Microsoft Copilot for M365 | Microsoft-ecosystem-native | M365-heavy orgs |
| Google Cloud Agentspace | Google-ecosystem | Google Workspace orgs |
| Slack AI | Slack-only | Slack-centric companies |
| Notion AI | Notion-only | Notion-heavy orgs |
| Coveo | Enterprise search (pre-AI era; evolving) | Established alternative |
| Algolia | Search-as-a-service | Different category (product search) |
| Mendel | Newer entrant | Comparable space |
Glean’s distinct position:
- Best-in-class cross-system search
- Vendor-neutral (works across many systems)
- Strong permissions management
- Strong AI capabilities
What it costs
Glean pricing is not public but indicators:
- Per-user pricing ranging based on size and features
- Substantial minimums (typically 100+ seats)
- Implementation costs in addition to subscription
- Annual contracts standard
Realistic estimate: For a 500-person organisation, expect 1M+ AUD annually all-in.
This is not for small businesses. Glean targets organisations where the productivity recovery justifies enterprise investment.
Privacy and security (enterprise-grade)
Glean operates in heavily-regulated enterprise space:
- SOC 2 Type II certified
- ISO 27001 certified
- HIPAA capable with BAA
- Permissions respected — never shows users content they can’t access
- Data residency options for enterprise (verify Australian options)
- Customer data isolation — strong tenant separation
- Encryption in transit and at rest
- Audit logs for compliance
For Australian organisations:
- Australian Privacy Act compliance through enterprise DPA
- APP 11 security obligations addressed through Glean’s certifications
- APP 8 cross-border disclosure considerations — review current Australian data residency status
- Industry-specific compliance (banking, healthcare, government) — discuss with Glean’s enterprise team
Australian considerations
- No specific Australian data centre as of mid-2026 — verify current status
- Latency from US hosting is acceptable for search use (not real-time)
- Enterprise sales process for Australia goes through Glean’s APAC team
- Australian customers growing but smaller market presence than US
Implementation realities
Glean implementation is substantial:
Time
- Pilot: 4-8 weeks typical
- Full deployment: 3-6 months for large organisations
- Ongoing optimisation and integration additions
Effort
- Connecting source systems
- Permission verification
- Knowledge graph training
- User onboarding and training
- Adoption change management
Success factors
- Strong executive sponsorship
- Active user adoption
- Continuous integration with new tools
- Quality of organisational documentation
This is enterprise software requiring enterprise attention, not a simple SaaS subscription.
Real workflows where Glean shines
”Where do I find…?”
Universal use case. Saves hours of hunting across systems.
Onboarding new employees
Glean reduces “ramp-up time” by letting new hires search for context independently.
Cross-functional collaboration
Finding what other teams are doing without disrupting them.
Customer service
Support reps finding solutions across knowledge bases, past tickets, product docs.
Sales support
Sales reps finding relevant case studies, past proposals, competitive intelligence.
Decision support
Leadership asking questions about organisational state.
What Glean is NOT
- Not a replacement for Microsoft Copilot if you’re M365-only (Copilot might be enough)
- Not for small businesses (cost-prohibitive)
- Not a project management tool (it searches existing tools)
- Not a CRM (it searches the CRM)
- Not magic — quality depends on quality of your underlying content
Common gotchas
- Garbage in, garbage out. If your organisational content is poor, search results will be poor.
- Permissions complexity can create surprises. Test thoroughly during pilot.
- Integration complexity with many source systems takes time.
- AI hallucinations possible even with RAG. Verify important answers.
- Adoption challenges — users need to actually use it.
- Pricing requires committing. Not easy to “try Glean” for small organisations.
Funding and growth
Cognition Glean raised substantial venture funding (separate from Cognition Labs the Devin company — confusingly similar names):
- Multiple funding rounds
- Multi-billion dollar valuation by 2024
- Strong enterprise growth metrics
The category — enterprise AI search — has many competitors but Glean has emerged as the leader for mid-market and enterprise.
