Growth Street Partners is a U.S. lower-middle-market growth-equity investment firm founded in 2016, providing operationally-focused growth capital to rapidly-growing SaaS companies and technology-enabled services businesses in North America, typically at USD 5 to 20 million in annual recurring revenue (ARR) scale. The firm is headquartered in the U.S. (primary office in Austin, Texas, with additional presence on the U.S. East Coast), and positions itself as a ''unique balance of capital and help'' provider focused on software and technology-enabled services rather than traditional PE buyouts. Growth Street typically writes initial equity investments in the USD 5 to 15 million range, structured as primary growth capital, secondary buy-outs of founders or early investors, or hybrid transactions, with a majority or significant-minority ownership stake. The firm has raised multiple institutional funds with aggregate AUM in the USD low-hundreds of millions range. Portfolio companies include Ameelio (before pivot), Capsule Technologies, Talkdesk (historical), and other lower-middle-market SaaS and tech-enabled-services businesses.
