Sumble: AI Sales Prospecting

Sumble: AI Sales Prospecting

22 October 2025

Sumble, founded by the creators of Kaggle, has emerged from stealth mode, aiming to revolutionise the sales prospecting market using AI. The company has secured $38.5 million in funding across seed and Series A rounds. Sumble's platform uses knowledge graphs and large language models to deliver contextual company intelligence, going beyond traditional prospecting data.

Since its launch in April 2024, Sumble has attracted 17 enterprise clients, including Snowflake, Figma, and Wiz, and has experienced a 550% increase in revenue. Sumble's platform dynamically mines public signals from social feeds, company sites, job boards and regulatory filings. It assembles them in a knowledge graph that explains what is happening inside target accounts and why it matters to a seller.

The company's focus is on offering deep account intelligence, enrichment, and intent to go-to-market teams. Sumble identifies org structures, tech stacks, and key projects like GenAI projects or cloud migrations. Sumble faces competition from established players and emerging AI sales agents in a crowded market.
