About
PartnerHQ is a San Francisco, California-based B2B warm introduction marketplace — backed with $500,000 in seed funding from Y Combinator (Winter 2024 cohort), 1Indicator, Rebel Fund, Sancus Ventures, and Maiora Ventures — connecting B2B companies seeking introductions to decision-makers with professional network connectors who earn paid bounties ($500 average per introduction) for facilitating warm introductions that replace cold outreach. Founded in 2023 by Stanford graduates Stan Liu and Katherine Wang, PartnerHQ launched in February 2024 and within its first year signed hundreds of paying companies with 97% of growth coming from inbound and word-of-mouth channels. The platform's founding thesis was validated through the founders' prior experience managing partnerships at Brackets For Good, a nonprofit that managed 150+ sponsors and 750 organizations across 12 markets raising $12 million for charities. PartnerHQ operates with a small founding team and builds what the founders describe as a professional relationship graph to match buyer needs with connector network access.
