Growth Street Partners

Growth Street Partners is a growth-stage investment firm founded in 2016 and headquartered in San Francisco. It provides early growth capital to rapidly growing vertical SaaS and technology-enabled services companies across the United States and Canada, with a stated focus on underserved markets.

The firm invests as a meaningful minority partner, a structure intended to allow founder-led businesses to scale without surrendering control. Its stated approach pairs capital with practical operational support: scaling sales and marketing, hiring professional executives, improving systems and processes, expanding addressable markets, and pursuing acquisitions. It describes its role as that of a sounding board to founders rather than a controlling owner.

Growth Street Partners closed its third fund in 2025, raising $200 million. The firm manages more than $400 million of fully committed capital. Sector coverage is concentrated in vertical SaaS - software built for specific industries or workflows - and technology-enabled services.

The firm positions itself as founder-friendly, working with founder-led businesses and aiming to help them expand while retaining ownership. Investment activity spans the United States and Canada.
