Sumble is a knowledge-graph and search platform aimed at the go-to-market problem: understanding, in depth, what is happening inside a target company. It connects disparate data points into a structured graph underpinned by large language models, then lets teams query that graph to learn which tools a company uses in which departments, what projects it is launching or running, how its organization is structured, what technology it may be looking to adopt, and crucially who to contact. The result is far richer than a static technographic list; it is contextual intelligence about a company's technology and initiatives.
The founders bring serious credibility to the data-and-ML challenge. Sumble was created by Anthony Goldbloom and Ben Hamner, the founders of Kaggle, the data-science and machine-learning community later acquired by Google. That background informs Sumble's approach of using a knowledge graph plus LLMs to make sense of messy, unstructured signals about companies and turn them into queryable intelligence.
Sumble emerged from stealth in October 2025 with $38.5 million in total funding, composed of an $8.5 million seed round led by Coatue and a $30 million Series A led by Canaan Partners. Additional investors included AIX Ventures, Square Peg, Bloomberg Beta, and Zetta, alongside angels such as Salesforce CEO Marc Benioff and former GitHub CEO Nat Friedman. Since launching its underlying product in April 2024, Sumble has signed enterprise customers including Snowflake, Figma, Wiz, Vercel, and Elastic, and reports tens of thousands of users.
The platform sits at the intersection of enterprise search and sales intelligence: it is essentially a search engine over a company-knowledge graph, surfacing the people, projects, and technologies that revenue teams need to find and act on. By grounding answers in structured relationships rather than scraping alone, Sumble aims to give sellers and researchers a more accurate, contextual view of their accounts.
For go-to-market and research teams that need to understand companies deeply, Sumble offers AI-powered context: a knowledge graph of tech stacks, projects, org structures, and contacts, made searchable so teams can move from raw signals to the right action and the right person.
