Sumble emerges from stealth with $38.5M in funding to bring real-time sales intelligence to GTM teams

After years under wraps, Sumble, a San Francisco-based startup founded by Kaggle creators Anthony Goldbloom and Ben Hamner, is stepping into the spotlight with a bold promise — to give go-to-market teams a live window into what’s really happening inside their target accounts.

Today, Sumble emerged from stealth with $38.5 million in Seed and Series A funding to build what it calls the world’s most advanced sales intelligence platform. The round was led by Canaan Partners and Coatue, joined by Square Peg Capital, Zetta Venture Partners, Bloomberg Beta, AIX Ventures, and angel investors Marc Benioff and Nat Friedman.

Sumble’s platform goes beyond traditional sales data tools. It continuously scans tens of millions of public data sources to map out organizational structures, tech stacks, and live technology initiatives such as cloud migrations and GenAI projects. By translating those findings into actionable insights, Sumble helps sales teams know who to contact, when to reach out, and why that moment matters.

“Sumble goes deeper than other GTM data vendors; they help us zero in on the designers who matter most to us (UX and visual) and filter out the ones who don’t,” said Elliott Straube, Go-To-Market Strategy Manager at Figma, one of Sumble’s early customers alongside Snowflake, Wiz, Vercel, Elastic, Atlan, Weights & Biases, Omni, Snyk, and Dataiku.

For sales leaders, that kind of precision can change the odds of landing a deal. “Sumble helps the field find the most relevant signals aligned to our sales motions, increasing our conversion rates,” said Jesse Sladek, VP of Sales Strategy and Enablement at Elastic.

Goldbloom, who sold Kaggle to Google in 2017, says the idea for Sumble grew out of a simple frustration: automation in sales wasn’t working because it lacked context. “Before joining Sumble, I sold an AI SDR product,” said Avishek Roy, founding Account Executive. “And what I saw again and again was that automation only works if it’s anchored in truly actionable signals.”

That conviction resonated with investors. “In a world of LLMs, context is everything,” said Rich Boyle, General Partner at Canaan Partners. “You can’t get meaningful AI-powered GTM outreach without a clean, accurate, and actionable data foundation. Sumble is building that foundation.”

Under the hood, Sumble’s engineering team is scaling fast. “We’re operating at a large scale,” said Akash Gajjar, one of the company’s early engineers. “Our crawlers parse a range of company-related pages daily. Then we layer AI models on top to extract the real signals — the things that actually matter to a GTM team — from all that noise.”

For a founder who helped shape the global data science community, Sumble feels like a natural next chapter. This time, Goldbloom and Hamner aren’t just collecting data — they’re giving sales teams the kind of insight that can make every outreach count.
