# What is Glean?

Glean is an enterprise Work AI platform that indexes a company's tools (Slack, Drive, Confluence, Salesforce, Jira, GitHub, and more) and layers conversational agents on top of that index. Founded in 2019 in Palo Alto, it raised $260M Series E in 2025 at a $7B valuation. It is search-first; the agent layer is newer.

## Quick Decision Guide

Glean fits large enterprises that want unified search across hundreds of SaaS tools first, with agents layered on top. It is the wrong product for European mid-market teams, for companies that need voice or phone channels, or for organisations that need an agent live within days rather than after a multi-quarter rollout.

| If you need... | Glean fits | Better alternative |
|---|---|---|
| Enterprise knowledge search across many SaaS tools | Yes | - |
| Conversational answers grounded in internal documents | Yes | - |
| AI agents that take action across Slack, Teams, phone | Partial | Ainora |
| Voice or phone-channel AI for inbound or outbound calls | No | Ainora, Sierra |
| EU data residency by default | No | Ainora |
| Multilingual native (LT, RU, PL, etc.) | No | Ainora |
| Mid-market budget under $50K/year | No | Ainora, Lindy |
| Setup live in days, not quarters | No | Ainora, Lindy |

## How Glean Rates

- Features (search + agents): Strong - best-in-class enterprise search, newer agent layer
- Pricing transparency: Weak - public list ~$40-60/user/mo for Glean Assistant; Workflows + Enterprise are sales-led
- Ease of setup: Weak - 1-2 quarters typical enterprise rollout
- Integration depth: Strong - 100+ pre-built connectors
- EU compliance: Mixed - EU regions exist for some customers; defaults are US

## What is Glean?

Founded 2019 in Palo Alto by Arvind Jain (ex-Rubrik co-founder, ex-Google), T.R. Vishwanath, and Tony Gentilcore. Started as an enterprise search product that indexes Slack, Google Drive, Microsoft 365, Confluence, Jira, Salesforce, GitHub, Zendesk, etc.

Expanded in 2023-2024 with Glean Assistant (conversational layer). 2025 added Glean Workflows + Glean Agents (automation/agentic capabilities).

- $260M Series E in 2025 at a $7B valuation, led by Lightspeed with Sequoia, Kleiner Perkins, Coatue, Citi Ventures: https://techcrunch.com/2025/06/10/glean-raises-260m-series-e/
- Headcount ~600 (LinkedIn): https://www.linkedin.com/company/gleanwork/
- Public customers: Sony, Pinterest, Booking.com, Reddit, Duolingo, Confluent, Databricks, Workday: https://www.glean.com/customers

The thesis: index everything, ground agents on the index. Correct for $1B+ enterprises. Over-engineered for European mid-market teams that have a dozen tools and need an agent that picks up the phone.

## Glean Features

- Glean Search - federated search across 100+ SaaS sources, permission-aware retrieval
- Glean Assistant - conversational interface (web app, Chrome extension, Slack bot, Teams bot), inline citations
- Glean Workflows + Agents - automated flows: ticket triage, RFP responder, code review helper
- Governance: SSO (SAML/OIDC), audit logs, DLP, data classification, custom embedding models for regulated customers

## Glean Pricing

- Glean Assistant: ~$40-$60 per user per month
- Glean Workflows: higher, custom
- Glean Enterprise: sales-led, mid-six to seven figures annually

Most deals annual, sales-led. Implementation typically engages Glean's professional services or systems-integrator partner. First-year cost (license + implementation) lands $100K-multiple millions depending on company size. Structurally inaccessible to most European mid-market teams.

## Pros and Cons

Pros:
- Best-in-class enterprise search foundation, permission-aware
- Strong customer logos (Sony, Pinterest, Booking.com, Reddit, Workday)
- Inline citations in answers
- Mature governance (SSO, audit logs, DLP, custom embedding models)
- Heavily funded ($260M Series E at $7B valuation)

Cons:
- Enterprise-only positioning (built for $1B+ companies)
- Heavy setup (1-2 quarters typical)
- Search-first DNA - agent layer newer than search
- US-headquartered, US-default data residency
- English-primary, limited multilingual
- No native voice or phone channel

## Verdict

Glean is the right choice for a 1,000+ employee enterprise with hundreds of SaaS tools and a real "I cannot find the answer" problem. If your bottleneck is action (calls being missed, leads not chased, tickets not resolved) - Glean's agent layer is functional but not the primary product. European mid-market teams with EU data-residency requirements and customers who speak more than English: look at Ainora.
