Harvey, a San Francisco-based legal artificial intelligence company, announced on September 24, 2026 that Teachers' Venture Growth (TVG), the late-stage venture and growth investment platform of Ontario Teachers' Pension Plan, completed a US$50 million investment in the company. Harvey and BNN Bloomberg both describe the investment as an extension of a financing round originally announced on September 9, 2026, which was co-led by Diffusion and Lightspeed Venture Partners and raised US$550 million at a US$15.5 billion valuation. With the Ontario Teachers' tranche, total capital raised in the round reaches US$600 million. Rick Prostko, senior managing director at Teachers' Venture Growth, said Harvey has built a strong position with Canadian customers and that Ontario Teachers', as a Canadian institution, is positioned to help accelerate it. The announcement also describes Harvey's broader push into the Canadian market, including new law firm and in-house customers and a new Toronto-based hire.
