Microsoft cloud executive Eric Boyd has jumped ship and is heading to Anthropic to serve as its head of infrastructure.

Boyd shared his career change in a post on LinkedIn, writing: "I'm excited to join the amazing team at Anthropic today, where I'll be leading the Infrastructure team! I've been privileged to have a front row seat to the explosion of LLMs, and the team at Anthropic is truly special.

"The combination of the absolute leading models with a culture that is committed to their mission is inspiring, and I can't wait to lean in to help."

Boyd started working at Microsoft in 2009. Beginning in 2018, he led the Azure AI team, which he said "set in motion the most exciting chapter of my career: watching large language models emerge, and having the privilege of bringing them to the world through the Microsoft Foundry and the Azure OpenAI Service. Riding that wave over the past three years has been extraordinary, and something I'll never stop being grateful for."

While leading the Azure AI team, Boyd assisted with the planning of the AI compute clusters for Microsoft that were used by OpenAI to train and run its models.

He joined Anthropic shortly after the AI startup began hiring veteran cloud executives, per a report from The Information. The company is said to have hired two former Google executives and is in discussions to secure more than 10GW of capacity over the next handful of years.

Earlier this month, Anthropic signed an agreement with Google and Broadcom that would see the development or lease of 3.5GW of TPUs, planned to come online from 2027.

In February 2026, Anthropic raised $30 billion in Series G funding, giving the generative AI company a post-money valuation of $380bn. The round was led by GIC and Coatue, and Microsoft and Nvidia also invested a portion of a previously promised $15bn investment. In a statement announcing the deal, Anthropic said its run-rate revenue (RRR) has reached $30bn, up from approximately $9bn at the end of 2025.
