Whenever people talk about Demis Hassabis and DeepMind, one other name always comes up: Mustafa Suleyman. He co-founded DeepMind, built his own AI company afterward, and now runs Microsoft AI as CEO. Here’s his full story.
Who Is Mustafa Suleyman?
Mustafa Suleyman CBE was born in August 1984. He’s a British AI entrepreneur with a fairly humble background — his Syrian father worked as a taxi driver, and his English mother worked as a nurse. He grew up in the Islington area of London.
Here’s an interesting detail: Suleyman’s friendship with Demis Hassabis actually goes back to their school days. They met through Hassabis’s younger brother, who was Suleyman’s best friend, and the two of them would talk about wanting to positively impact the world even back then.
Before DeepMind: Social Impact Work
Before starting DeepMind, Suleyman worked in human rights — as a policy officer for London Mayor Ken Livingstone. He later started Reos Partners, a consultancy that used conflict-resolution methods to tackle social problems, working with clients like the United Nations.
Co-Founding DeepMind (2010)
In 2010, Suleyman co-founded DeepMind alongside Demis Hassabis and Shane Legg, taking on the role of Chief Product Officer. In 2014, Google acquired DeepMind for £400 million — Google’s largest European acquisition at the time. Suleyman later became Head of Applied AI, responsible for integrating DeepMind’s technology into Google’s actual products.
He also founded DeepMind Ethics & Society, an initiative focused on exploring the real-world implications of AI.
Inflection AI: His Own Company
After leaving Google in 2022, Suleyman co-founded Inflection AI. In 2023, they launched “Pi,” a chatbot whose name stood for “Personal Intelligence.” Pi was designed to be conversation-focused — it remembered past conversations and offered emotional support, more like a digital “Chief of Staff” than a search tool.
The Move to Microsoft AI (March 2024)
In March 2024, Microsoft appointed Suleyman as EVP and CEO of Microsoft AI, its new consumer AI division. Several members of the Inflection AI team joined him at Microsoft, including co-founder Karén Simonyan, who became Chief Scientist.
Microsoft CEO Satya Nadella said at the time that he had admired Suleyman as a visionary founder and builder for years.
A Major Shift in 2026: Toward Superintelligence
In March 2026, Microsoft restructured its Copilot organization. Suleyman’s focus shifted toward frontier AI models and superintelligence, while day-to-day Copilot operations moved to a new leader, Jacob Andreou, a former Snap executive. Suleyman still reports directly to Satya Nadella.
The MAI Superintelligence Team, formed in November 2025, is now his primary mandate — with a goal of delivering frontier-grade AI models within the next five years.
Microsoft Build 2026: A Major Announcement
At Build 2026, Suleyman unveiled seven new in-house AI models — a significant departure, since Microsoft had historically relied heavily on OpenAI’s models across its products (Word, Excel, Teams, GitHub). The first text-based reasoning model, MAI-Thinking-1, is a trillion-parameter system.
Suleyman was candid about where Microsoft actually stands — he openly acknowledged the company isn’t yet among the top four AI labs (behind Google DeepMind, OpenAI, and Anthropic). Getting onto that list is his stated goal.
The “Humanist Superintelligence” Vision
Suleyman’s philosophy differs from other AI leaders in a notable way. He uses the term “Humanist Superintelligence” — AI that’s extremely capable, but stays “problem-oriented and domain-specific” rather than becoming a fully autonomous, unbounded system. His focus is keeping humans in control, no matter how advanced the AI becomes.
