The data scientists who built machine learning community Kaggle just raised $38.5 million to shake up sales intelligence with context-driven AI. Sumble emerged from stealth Wednesday with backing from Coatue and Canaan Partners, claiming it can surface deeper company insights than traditional prospecting tools by connecting scattered web data through knowledge graphs.
The machine learning heavyweights behind Kaggle are betting they can out-AI the sales intelligence giants. Anthony Goldbloom and Ben Hamner just emerged from stealth with Sumble, raising $38.5 million to bring what they call "contextual intelligence" to the crowded world of sales prospecting.
The funding comes in two tranches - Coatue led an $8.5 million seed round, while Canaan Partners headed up a $30 million Series A. AIX Ventures, Square Peg, Bloomberg Beta, and heavyweight angels including Salesforce CEO Marc Benioff and former GitHub CEO Nat Friedman also joined the round.
What makes this interesting isn't just the Kaggle pedigree. It's how quickly enterprise customers are adopting the platform. Since launching in April 2024, Sumble has signed 17 enterprise clients including Snowflake, Figma, Wiz, Vercel, and Elastic. The company declined to share revenue figures, but sources familiar with the matter tell us revenue jumped 550% year-over-year.
"What tends to happen is, we go viral inside a company," Goldbloom told TechCrunch. "We'll go from 1 to 500 monthly active users in a company over six months. It spreads through Slack channels, then teams, then offices."
The viral growth story reflects what Sumble is trying to solve - sales teams drowning in data but starving for context. Traditional sales intelligence platforms like ZoomInfo and Apollo.io excel at contact discovery and basic company information. But Sumble claims its knowledge graph approach delivers deeper insights by connecting dots across social media, job boards, regulatory filings, and company websites.
The platform uses large language models to process this scattered data and surface what Goldbloom calls "technographic intelligence" - which tools companies use in specific departments, ongoing projects, organizational changes, and crucially, technology adoption signals that indicate buying intent.
"Sales teams need more than data; they want context," Goldbloom explained. The knowledge graph covers 2.6 million companies globally, and about 30% of users convert to paid Pro subscriptions that offer workflow integrations and prospect alerts.
But Sumble enters a battlefield littered with competitors. Beyond incumbents like HubSpot and Outreach, the space is seeing an explosion of AI-powered sales development representatives and specialized tools from companies like Cognism, SalesLoft, and Reply.io. The question isn't whether AI will transform sales intelligence - it's who will own the category.
Goldbloom's confidence stems from Sumble's knowledge graph architecture. "The more data we add, the richer the corpus becomes. We view the richness of the knowledge graph as a massive source of defensibility," he said. The company is also betting on LLM integration, structuring its data so AI assistants like ChatGPT can query Sumble's intelligence directly.
The investor lineup tells its own story about market validation. Rich Boyle, now a Canaan general partner, was a board observer at Kaggle. Bloomberg Beta and Zetta also backed the original Kaggle. Though Goldbloom co-founded AIX Ventures, he stepped away before the firm considered investing in Sumble to avoid conflicts.
That familiarity likely helped, but the real draw seems to be customer traction in a notoriously difficult market. Enterprise sales tools face high switching costs and entrenched workflows. Yet Sumble's viral adoption pattern suggests it's solving a real pain point that existing solutions miss.
The timing feels right too. As companies tighten sales budgets, the pressure intensifies to make every prospect interaction count. Generic outreach isn't cutting it when buyers expect personalized, contextually relevant conversations. If Sumble can deliver that context at scale through AI, it could carve out meaningful market share even in this crowded field.
The Kaggle founders are making a calculated bet that sales intelligence needs more than better data - it needs smarter context. With $38.5 million in funding and impressive early traction among enterprise customers, Sumble has the resources to prove whether knowledge graphs and LLM integration can differentiate in this crowded market. The real test will be maintaining that viral growth while competing against well-funded incumbents and an army of AI sales agents all promising to revolutionize prospecting.
