Leadspace
Leadspace is a B2B data intelligence company that unifies buyers, accounts, and buying signals into a single continuously updated data layer for go-to-market teams. Its GTM Data Intelligence Cloud enriches, scores, and activates data across CRM and marketing systems like Salesforce, Marketo, and HubSpot, helping sales and marketing teams find, segment, and prioritize their ideal customers.

Demandbase
Demandbase is a San Francisco-based B2B go-to-market software company that pioneered account-based marketing (ABM) and now runs Demandbase One, a unified platform combining account intelligence, intent data, advertising, sales intelligence and AI agents. It helps revenue teams identify in-market accounts, coordinate marketing and sales across channels, and turn buyer signals into pipeline. Founded in 2006 by Chris Golec and led by CEO Gabe Rogol, the company serves hundreds of enterprise B2B customers.
LeadGenius
LeadGenius is a Berkeley-based B2B contact-data and buyer-intelligence company that blends machine learning with a globally distributed team of human researchers to build custom, compliance-first datasets for revenue teams. Rather than reselling a static database, it sources contact and account data on demand for each client, verifying every record before delivery, and layers in signals like role changes, technographics and buying-committee mapping. Spun out of the crowdsourcing startup MobileWorks in Y Combinator's 2011 class, the company pairs its data business with a social mission: it was the first crowdsourcing firm to tie worker pay to local living wages.
Sumble
Sumble is a San Francisco AI startup building a knowledge graph of the world's external company data. Founded by Kaggle creators Anthony Goldbloom and Ben Hamner, it crawls job boards, company sites, social media, and regulatory filings, then uses large language models to surface technographics, org charts, and active projects for go-to-market teams. It emerged from stealth in October 2025 with $38.5M in funding and covers roughly 2.6 million companies worldwide.
FTN (For The Numbers)
FTN - short for For The Numbers - is a Las Vegas-based sports data and media company that turns advanced NFL, MLB and NBA numbers into fantasy and betting tools. Launched in 2020 (when the only live sport was Korean baseball), it now runs a network of subscription sites for season-long fantasy, daily fantasy, and sports betting, publishes articles, podcasts and livestreams, and is the new home of Aaron Schatz's DVOA metric after Football Outsiders closed. It serves both consumers who want an edge in their leagues and B2B clients who license its proprietary data.
Surfe
Surfe is a connected revenue workspace that bridges LinkedIn and CRMs so sales teams can find, enrich, and sync prospect data without leaving their browser. Its browser extension and waterfall enrichment engine chain 15+ data providers to deliver verified emails and mobile numbers, and its buying-signal layer flags which prospects are ready to talk today. Founded in Paris in 2020 as Leadjet by David Maurice Chevalier and Romain Ginestou, the company rebranded to Surfe in 2022 alongside a EUR4M seed round, and now serves teams at companies like Google, Uber, Amazon Web Services, Spendesk, and Pigment.

People Data Labs
People Data Labs is a data-as-a-service company that sells clean, structured B2B data through developer-friendly APIs. Instead of selling dashboards or seats, it sells the raw material - billions of professional and company records that engineers, data scientists, and product teams use to build their own tools for recruiting, sales, marketing, identity verification, and AI. Founded in 2015 and headquartered in San Francisco, the company positions itself as the data layer underneath other companies' products rather than a competitor to them.
