Whether you’re researching industry leaders, discovering influential voices, following emerging startups, or simply learning who’s shaping the future of AI, this directory provides a structured place to begin.
Who’s Who in AI
There are currently 5 names in this directory beginning with the letter S.
Sam Altman
CEO, OpenAI
Sam Altman is the co-founder and CEO of OpenAI, having transformed what began as an obscure nonprofit research lab into a household brand valued at $300 billion — the highest valuation ever achieved by a private tech company. Before OpenAI, he was president of Y Combinator, the storied Silicon Valley accelerator.
In January 2025, Altman appeared alongside President Trump, Larry Ellison, and SoftBank's Masayoshi Son to announce Stargate — a joint venture committing up to $500 billion to build AI data center infrastructure across the United States.
As recently as June 2026, Altman was on Capitol Hill meeting with the Trump administration and congressional leaders on both sides of the aisle to discuss the future of AI regulation, advocating for a "light touch" framework.
OpenAI has not been without controversy under his leadership. Twelve former employees filed an amicus brief in 2025 describing Altman as someone who had directly misled staff, while OpenAI countersued Elon Musk, claiming his legal challenges were deliberate tactics to slow the company for his own competitive benefit.
Altman's stated mission remains building artificial superintelligence — and by most accounts, he is the person most likely to get there first.

Sam Rodriques
Co-founder and CEO, FutureHouse
Sam Rodriques is a physicist and bioengineer who earned his PhD in Physics from MIT, working across the MIT Media Lab, the Department of Brain and Cognitive Sciences, and the Broad Institute. Before FutureHouse, he ran a bioengineering lab at the Francis Crick Institute in London, inventing technologies for brain mapping, gene therapy, and spatial transcriptomics.
In 2023, Rodriques co-founded FutureHouse — a nonprofit with a single audacious goal: build AI scientists capable of formulating hypotheses, conducting experiments, and analyzing data autonomously. Backed by Eric Schmidt, the lab has moved fast.< br />
FutureHouse's PaperQA became one of the first AI agents to achieve superhuman performance on scientific literature search tasks, beating PhD and postdoc-level researchers on objective benchmarks. In November 2025, the lab launched Kosmos, an AI Scientist that users estimate does six months of work in a single day — reading up to 1,500 papers, writing 42,000 lines of code per run, with at least 79% of its findings reproducible.
The first real-world discovery followed. In May 2025, FutureHouse's agents identified a promising new treatment for dry age-related macular degeneration, a leading cause of blindness — with AI handling everything except physical lab work and the final manuscript.
In 2025, Rodriques spun out Edison Scientific, a for-profit company to commercialize FutureHouse's agents. TIME named him to its 100 Most Influential People in AI 2025 list.

Shane Legg
Co-founder and Chief AGI Scientist, Google DeepMind
Shane Legg CBE is a New Zealand-born machine learning researcher who co-founded DeepMind Technologies in 2010 alongside Demis Hassabis and Mustafa Suleyman. He holds a PhD from the Dalle Molle Institute for Artificial Intelligence Research in Switzerland, where his thesis proposed a formal definition of machine intelligence — work that earned him the Canadian Singularity Institute research prize.
While Hassabis leads the company, Legg occupies a quieter but equally consequential role. As Chief AGI Scientist, he leads the Technical AGI Safety team, focused on mitigating existential risks from advanced AI systems through alignment techniques and robustness testing. He oversees much of DeepMind's research direction and is deeply involved in recruiting and shaping the scientific culture of the organization.
His concern about AI risk is longstanding and on the record. Legg raised the issue of existential risk from AI as early as 2011 in an interview on LessWrong, and in 2023 signed the statement on AI risk of extinction — placing him among the founders who built the technology and have been most candid about its dangers.
His doctoral thesis was titled "Machine Super Intelligence." That he is now the person inside one of the world's most advanced AI labs responsible for ensuring that superintelligence remains safe is either reassuring or sobering — possibly both.

Strive Masiyiwa
Founder and Executive Chairman, Cassava Technologies
Strive Masiyiwa founded Econet in Zimbabwe in 1993 after a five-year legal battle with the government to win a telecoms licence against a state monopoly — a fight that became emblematic of his career-long willingness to challenge established power structures. He went on to build Econet into one of Africa's largest telecom groups, operating across more than 20 countries.
Cassava Technologies, his pan-African digital services company, is now at the center of his most ambitious push yet. Masiyiwa has announced a $720 million plan to build Africa' s first network of AI factories — powered by Nvidia GPUs — across South Africa, Nigeria, Kenya, Egypt, and Morocco, under what he calls a Sovereign AI Cloud strategy aimed at giving African nations the infrastructure to develop and run their own AI systems.
Cassava launched Africa's first Nvidia-powered AI factory in South Africa in March 2026, with a second facility in Johannesburg in development. Cassava has also secured equity investment from Nvidia itself, making it one of the few African tech companies backed by a leading Silicon Valley chipmaker.
Most recently, Cassava backed the newly launched AI Skills and Compute Africa Foundation in Kigali, targeting one million young people transitioned into AI-related work and 25,000 developers awarded compute grants.
His framing is direct: "I helped pioneer Africa's mobile revolution and then Africa's high-capacity broadband. Now we are driving the continent's AI revolution."

Stuart Russell
Co-founder and President, International Association for Safe and Ethical AI
Stuart Russell is a professor of computer science at UC Berkeley, holder of the Smith-Zadeh Chair in Engineering, and director of the Center for Human-Compatible AI. His textbook "Artificial Intelligence: A Modern Approach," co-authored with Peter Norvig, is the standard text in the field — used in over 1,500 universities across 134 countries.
Since 2013, Russell has been warning that building AI systems more intelligent than humans, when we still do not reliably know how to control them, could destroy civilization. That conviction has been his north star across decades of work and public advocacy.
His most recent institutional move is IASEAI. "There were many people and over a hundred organizations concerned with AI ethics and safety, but they had no collective voice and no collective means of action," Russell says — and that gap led him to co-found the International Association for Safe and Ethical AI. The organization's inaugural conference in Paris in February 2025, held ahead of the Paris AI Action Summit, drew more than 700 in-person attendees and 1,400 online, including Nobel laureates Geoffrey Hinton and Yoshua Bengio, and MIT physicist Max Tegmark.
Russell has been direct in his public commentary on industry practices. He has argued that the Paris AI Summit sidelined safety in favor of commercial interests, and called for "cast-iron guarantees" that AI systems won't cause harm.
