Feb 2025Undisclosed stageTeachers’ Venture Growth (lead); Intrepid Growth Partners$235M$2.5BStackAdapt is a Toronto-based multi-channel programmatic advertising platform that empowers marketers with AI-driven automation across 19 global markets, headquartered in Canada with over 1,300 employees. On February 4, 2025, it announced a $235 million USD all-equity growth capital raise led by Teachers’ Venture Growth (TVG), the late-stage investment arm of Ontario Teachers’ Pension Plan, with participation from Intrepid Growth Partners (its first investment) and four undisclosed investors. The round, mostly secondary, valued the company near $2.5 billion USD, following a $300 million USD investment from Summit Partners in 2022 at $1 billion USD valuation, bringing total funding over $500 million USD. The funding will support R&D scaling, innovation in AI and automation, global expansion into Europe, Latin America, and Asia, hiring, and tech stack development beyond its North American focus. StackAdapt is positioned as a leader in ad tech, building its own stack since 2014 and flying under the radar compared to larger DSPs, with plans to enhance credibility and attract more enterprise advertisers. Financially, StackAdapt is projected to surpass $500 million USD in revenue and $125 million USD in operating earnings for 2025, per The Globe and Mail, with the company confirming these figures are within range. It recently hired CFO Cassandra Hudson in September 2024, signaling IPO preparations, describing public listing as a short-to-medium term possibility while prioritizing private growth.
Jan 2022Undisclosed stageSummit Partners (lead)$300M$1BStackAdapt is a Canada-based demand-side platform (DSP) and programmatic advertising company founded in 2014 by Vitaly Pecherskiy, Yang Han, and Ildar Shar. The company built a next-generation advertising technology stack focused on AI and automation, delivering a self-serve platform that helps advertisers and media buyers with programmatic media buying. In 2022, Summit Partners led a $300 million minority growth investment that valued StackAdapt at $1 billion USD. This investment marked a significant inflection point for the company, which had largely bootstrapped and operated under the radar for its first eight years. Following Summit's investment, StackAdapt scaled operations across North America, EMEA, and APAC, recruited key executives including a CRO, CFO, CPO, and CMO, and continued to evolve its product toward a unified, AI-enabled marketing solution incorporating paid media, first-party data, email, and intelligent automation. The company remained focused on its core mission to disrupt the digital marketing landscape while maintaining profitability and consistent growth. In February 2025, StackAdapt secured an additional $235 million minority investment led by Teachers' Venture Growth, bringing total funding to over $500 million and valuing the company near $2.5 billion USD, with expectations to exceed $500 million in annual revenue and $125 million in operating earnings.
