Jim Keller, who joined the Toronto-headquartered artificial-intelligence chip firm as CTO and president in January 2021, has swapped roles with founder and CEO Ljubisa Bajic, he said in a LinkedIn post. Tenstorrent also named Keith Witek as COO on Monday. He was most recently director of strategic alliances at Google, and before that an executive at Tesla Motors and chip giant AMD. (The Logic)

Talking point: Bajic started the firm in March 2016; Keller, a colleague at AMD, wrote the first angel cheque. Tenstorrent has since raised US$233.7 million in venture funding, per PitchBook data. Investors include Fidelity Management and Montreal’s Real Ventures. It’s not alone—AI and ML semiconductor startups took in US$12.56 billion in capital across 351 deals over the last two years. Tenstorrent had previously announced it would launch its Greyskull processor commercially in May 2021, but has delayed that to develop software that clients will use with the chips, said Bob Grim, vice-president of communications. He said the firm plans to add 100 engineers this year to its 280-person staff.
