Sumble Raises $38.5M to Advance AI Sales Intelligence Platform

Sumble, a San Francisco-based startup founded by Kaggle creators Anthony Goldbloom and Ben Hamner, has emerged from stealth with $38.5 million in Seed and Series A funding led by Canaan Partners and Coatue, with participation from notable investors including Marc Benioff and Nat Friedman. The company offers an advanced sales intelligence platform that continuously scans tens of millions of public data sources to provide granular, real-time insights into organizational structures, technology stacks, and live initiatives such as cloud migrations and GenAI projects within target accounts. This context-aware data helps go-to-market teams identify the right contacts and optimal timing for outreach, improving conversion rates and enabling more effective sales motions. Early customers include major tech firms like Figma, Snowflake, Wiz, Vercel, and Elastic, who praise Sumble for its precision in filtering relevant signals and enabling timely, evidence-based engagement. Sumble's platform addresses the limitations of traditional sales tools by going beyond firmographics and contact lists to deliver actionable intelligence, reducing wasted effort and increasing sales effectiveness. The company plans to use the new funding to expand operations and further develop its AI-powered data capabilities at scale.
