Founder Fridays: How second-time founders build with Frank Greeff, co-founder of Kinso

Welcome to Founder Fridays - a Notion founder series - where we sit down with builders who’ve been in the trenches to talk shop - product, design, and the real lessons no one puts on a slide deck. Frank Greeff, Co-founder of Kinso, joins Alex Dam, Notion’s APAC Startups Lead, to share what it takes to build again with conviction after exiting Realbase at 29. Drawing on scaling a 400-person company and now leading a 17-person “unreasonable” team, Frank breaks down why focus beats size, why choosing the right battle matters, and why in AI, trust and context win over speed.
