Sumble, a new AI-driven sales intelligence startup founded by Kaggle co-founders Anthony Goldbloom and Ben Hamner, has emerged from stealth with $38.5 million in funding to help sales teams truly understand what’s happening inside target companies — not just who to contact.
The funding includes an $8.5 million seed round led by Coatue, and a $30 million Series A led by Canaan Partners, with participation from AIX Ventures, Square Peg, Bloomberg Beta, Zetta Venture Partners, and high-profile angels like Marc Benioff (Salesforce CEO) and Nat Friedman (former GitHub CEO).
Beyond Data: Context That Drives Action
Sales teams today have no shortage of tools — from ZoomInfo to Apollo.io — yet most still struggle to piece together a clear, dynamic picture of their prospects. Sumble tackles that by gathering and connecting live intelligence across social media, company websites, regulatory filings, job boards, and more, surfacing insights about technologies used, organizational changes, and active initiatives within each company.
At the heart of the platform lies a knowledge graph powered by large language models (LLMs), which links millions of disparate data points into an actionable, context-rich network spanning 2.6 million companies worldwide.
“Salespeople don’t just want more data — they want context,” said Anthony Goldbloom, CEO and co-founder of Sumble. “We’re building a system that understands what’s happening inside a company — who’s driving what project, what tools they’re using, and where opportunities are emerging.”

Rapid Growth and Viral Adoption
Since quietly launching in April 2024, Sumble has signed 17 enterprise customers, including Snowflake, Figma, Wiz, Vercel, and Elastic, with tens of thousands of active users. Roughly 30% of users have upgraded to paid plans — an unusually high conversion rate in the sales intelligence category.
The company claims 550% year-over-year revenue growth, driven entirely by word of mouth.
“We tend to go viral inside companies,” Goldbloom said. “We start with one user, then a Slack channel, then an entire team — and within months, we’re serving hundreds of users across the organization.”
Standing Out in a Crowded Market
The sales intelligence landscape is brimming with incumbents and AI upstarts, but Sumble believes its contextual knowledge graph provides a long-term moat.
“The richness of our knowledge graph becomes a massive source of defensibility,” Goldbloom explained. “The more data we ingest, the more interconnected and valuable the system becomes.”
This structure also positions Sumble at the intersection of AI and enterprise data, making its dataset natively queryable by large language models.
“You can imagine asking ChatGPT about a company’s tech stack — and getting an answer powered by our live, structured data,” said Goldbloom. “That’s where we see the future of AI in enterprise sales intelligence.”
What’s Next
Currently available as both a web app and API, Sumble’s paid tier integrates directly into CRM systems and workflows, offering notifications when key developments happen inside a prospect organization — from leadership changes to new product launches.
With its new funding, the company plans to expand its team, deepen integrations with sales and marketing platforms, and continue refining its AI models to deliver increasingly granular company intelligence.
