Andrew Tulloch education qualifications: The Sydney University medalist and Cambridge topper who said no to Meta's $1.5 billion offer

In Silicon Valley, few stories spread faster than one involving a billionaire's offer, and someone bold enough to refuse it. That's exactly what happened when Andrew Tulloch, a low-key but highly respected Australian computer scientist, turned down a job offer from
Mark Zuckerberg
's Meta, an offer reportedly worth up to $1.5 billion over six years, according to the
Wall Street Journal
.
But Tulloch's decision didn't come out of nowhere. It was backed by a career built on intellectual rigor, world-class research, and an academic journey that reads like a roadmap to AI excellence. From earning Australia's top school scores to topping exams at Cambridge, Tulloch's story is one of sustained brilliance and meaningful choices.
The Perth Prodigy
Tulloch's academic journey began at Christ Church Grammar School in Claremont, Western Australia.
Even in school, he stood out not just as a scholar, but as a leader and all-rounder. He graduated with a TER (Tertiary Entrance Rank) of 99.95, the highest possible in the state, placing him in the top percentile of Australian students.
He wasn't just a high scorer on paper. Tulloch served as school vice-captain, led his teams as captain of debating and mock trials, and was a member of the 1st XI cricket and hockey teams. It was clear early on: this was a student with both academic firepower and leadership flair.

Academic brilliance at
University of Sydney
In 2007, Tulloch enrolled in the Bachelor of Science (Advanced Mathematics) program at the University of Sydney, where he focused on mathematics and statistics—disciplines that would later power breakthroughs in AI.
He didn't just graduate with First Class Honours, but he was also awarded the University Medal, the highest academic distinction given to the top-performing honours student in the Faculty of Science.
Tulloch also received the Science Achievement Prize for having the highest GPA across the entire faculty.
At this stage, Tulloch had already marked himself as one of the top young minds in Australia.
Mastering math at Cambridge
Driven by a thirst for deeper theoretical knowledge, Tulloch crossed the globe to study at the University of Cambridge, enrolling in the elite Part III of the Mathematical Tripos, widely regarded as one of the most challenging postgraduate math programs in the world.
At Trinity College, Tulloch pursued a Master of Mathematical Statistics, specialising in statistics and machine learning. Once again, he rose to the top. Graduating with Distinction, Tulloch earned a prize from Trinity College for achieving the highest grade in his cohort.
T
his combination of raw intellect, mathematical precision, and international training became the foundation of his future impact in AI.
Beyond academia: From
Goldman Sachs
to
OpenAI
Tulloch's professional journey mirrored his academic one: disciplined, ambitious, and focused. After a brief stint as a strategist at Goldman Sachs, where he applied quantitative modelling to financial markets, he joined Meta (then Facebook) in 2012.
There, over more than a decade, Tulloch helped build the AI infrastructure that powers Meta's platforms including major contributions to PyTorch, now one of the world's most widely used machine learning frameworks.
In 2023, Tulloch joined OpenAI, where he worked on GPT‑4, GPT‑4o, and other advanced reasoning systems. Just over a year later, in 2025, he co-founded Thinking Machines Lab with former OpenAI CTO Mira Murati: a startup aiming to build transparent, customisable, and safe AI at scale.
When $1.5 billion isn't enough
It was shortly after launching Thinking Machines Lab that Meta came knocking again—this time with an aggressive push to recruit Tulloch and his team. According to
WSJ
, Tulloch was offered a compensation package worth up to $1.5 billion over six years.
That figure included stock options, bonuses, and long-term incentives.
But Tulloch said no. In fact, not a single member of his team defected to Meta.
Why? For Tulloch, it was never just about money. The opportunity to build something meaningful, aligned with his vision of responsible AI, mattered more than a billion-dollar payout.
Lessons from a billion-dollar rejection
Andrew Tulloch's academic path, from a perfect TER score to topping Cambridge's toughest math program, is not just a story of rare intelligence.
It's a story of discipline, curiosity, and long-term thinking.
In a tech landscape often obsessed with shortcuts, Tulloch's journey proves that a solid educational foundation still matters, perhaps more than ever. He reminds us that it's not always the biggest offer that shapes your future, but the biggest purpose.
