Common Room is a customer intelligence platform built for B2B go-to-market teams. Founded in 2020 by Linda Lian, Francis Luu, Viraj Mody, and Tom Kleinpeter - whose backgrounds span Facebook, Dropbox, and Madrona Venture Group - the company emerged from stealth in 2021 and has raised $52 million from investors including Greylock, Index Ventures, and Madrona.
The platform aggregates buying signals from sources such as Slack, Discord, GitHub, and social channels, then applies AI enrichment and automation to help GTM teams identify who to target, when to engage, and how to convert. By centralising signals that would otherwise sit across disparate communication and developer platforms, Common Room aims to give sales, marketing, and revenue operations teams a more complete picture of prospect and customer behaviour.
Common Room serves thousands of GTM teams, with customers including Notion, Figma, Airtable, and Confluent. Its technical scope spans data integration, signal aggregation, AI enrichment, and workflow automation - areas that sit at the intersection of data engineering, machine learning, and product development.
