Sumble

Sumble (operating at sumble.com) is an AI-powered account intelligence platform engineered for enterprise sales teams. Founded in 2022 and headquartered in San Francisco, CA, Sumble redefines sales intelligence by providing granular, context-rich data that traditional tools often overlook. Unlike generic prospecting platforms, Sumble specializes in crawling public sources—including social media, job boards, and company websites—to construct detailed knowledge graphs of target organizations. Under the hood, its technology aggregates technographic and contact data, mapping out team structures, account hierarchies, and emerging signals (like hiring trends) to deliver actionable insights. This empowers sales and GTM teams to identify high-potential prospects at a granular level, validate account signals before engagement, and tailor outreach with precision. Backed by $47M in funding, Sumble has emerged from stealth with a clear focus on democratizing enterprise-grade intelligence for mid-market and large organizations.
