Article Summary

Sumble is tackling the crowded sales intelligence market with a unique approach centered around a knowledge graph. The startup, founded by Anthony Goldbloom and Ben Hamner (also of Kaggle), aims to provide sales teams with the contextual data they need to identify and engage with potential customers. By trawling a massive dataset including social media, job boards, company sites, and regulatory filings, Sumble constructs a rich understanding of a company's technical stack, projects, and organizational structure. This information is then connected through a knowledge graph underpinned by large language models, allowing users to query for detailed insights, such as identifying the key technologies a company utilizes or who to contact within a specific department. The company’s rapid growth – 19 enterprise customers signed in April 2024, with revenues up 550% year-over-year – is attracting investors, including Canaan Partners, Coatue, and Salesforce CEO Marc Benioff. Sumble’s competitive advantage lies in the depth and breadth of its knowledge graph, covering approximately 2.6 million companies, coupled with the scalability offered by large language models. The startup’s vision is that querying the knowledge graph with an LLM will allow for a highly targeted and contextualized approach to sales intelligence, transforming how sales teams operate.
