Founder story
Founded in 2017 by Kevin Yun in Chicago. Kevin wanted to build a referral tool that was as easy to integrate as a snippet of code, removing the need for custom-built internal referral engines. He has since scaled GrowSurf into a leading player in the B2B referral space while remaining capital-efficient.
