Glean tripled its revenue to $300M ARR in just fifteen months and it did that while Microsoft, Google, OpenAI and Anthropic were all shipping copies of its core product.

The surprising part is where the money actually came from: not net-new logos, but existing accounts that started in one department and spread to five or more.

In today’s issue we’ll reconstruct the exact land-and-expand and pricing machine behind that curve: how a $60K single-team land becomes a $500K-to-$5M company-wide account and why “cut your AI bill” became the pitch that outran the giants.
