There is a moment in every startup\u2019s life when imagination eventually gives way to math. I\u2019ve heard this story hundreds of times before. Founders are rewarded for vision and lauded as dreamers. They pitch an idea, raise a Seed round, build their first product, and iterate.<\/p>\n\n\n\n


As Shay Grinfeld, a General Partner at Greenfield Partners, said, companies repeat this loop \u201c20 or 30 times\u201d until they land on the one product when the penny drops. \u201c\u2018They said \u2018You know what, actually hits a nerve\u2019,\u201d he told me. For this episode, I spoke to Grinfeld about being an early growth investor, and what happens when companies reach their initial targets in revenue: An achievement, of course, but also the beginning of a much harder phase.<\/p>\n\n\n\n

\u201cThat\u2019s when we meet them,\u201d Grinfeld says. The point where early momentum must turn into durable growth, usually around Series B and C, optimism alone is no longer enough. Growth investors arrive with a different question: can this company scale its go-to-market strategy once identifying a successful product-market fit, and will it do this faster than the cost of capital?<\/p>\n\n\n\n
