Ontario Teachers' Pension Plan Board led a $222m Series E round in Graphcore, a British semiconductor company that develops accelerators for AI and machine learning, with participation from Baillie Gifford and Draper Esprit. "Having the backing of such respected institutional investors says something very powerful about how the markets now view Graphcore. The confidence that they have in us comes from the competence we have demonstrated building our products and our business. We have created a technology that dramatically outperforms legacy processors such as GPUs, a powerful set of software tools that are tailored to the needs of AI developers, and a global sales operation that is bringing our products to market," Nigel Toon, Graphcore CEO.
