News of the Day

Sumble, a San Francisco-based startup founded by Kaggle co-founders Anthony Goldbloom and Ben Hamner, has raised $38.5 million in funding to bring deeper context to the crowded sales intelligence market. The funding includes an $8.5 million seed led by Coatue and a $30 million Series A led by Canaan Partners, with participation from AIX Ventures, Bloomberg Beta, Zetta, and angels like Marc Benioff and Nat Friedman. Unlike traditional tools that scrape and sell contact data, Sumble uses a knowledge graph powered by large language models to map relationships across 2.6 million companies — identifying which technologies teams use, what projects they’re running, and who to reach out to. Since its April 2024 launch, the company has quietly amassed 19 enterprise clients, including Snowflake, Figma, Wiz, and Elastic, and seen 550% year-over-year growth, often spreading virally inside companies through Slack and team channels. Goldbloom believes Sumble’s rich, queryable data corpus — designed to work seamlessly with LLMs — will make it an essential contextual layer for the next generation of AI-driven sales tools.
