Elizabeth Stone: Rise of a woman leader in the tech world

Elizabeth Stone is the woman who’s making waves in a highly male-dominated industry of technology, soaring high, and breaking barriers as Netflix’s Chief Technology Officer.

Stone’s rise through the tech world isn’t an ordinary success story; if anything, it says a lot about grit, consistent grind, and managing to break boundaries with persistent hustle. And in case you’re looking for a story about shifting gears, creative problem-solving, and leaving your markin the professional world, hers is one to take note of.

Early life and switching lanes: From finance to tech

For many, this may come as a surprise, but Stone didn’t start as a typical engineer. In fact, she came up through economics and finance, which shaped how she tackles problems in tech today. She earned her undergraduate degree, a Bachelor of Science degree, from the Massachusetts Institute of Technology (MIT). Then, she went on to complete a PhD from Stanford University, one of the leading research universities in the world.

Early on, she worked as a trader at Merrill Lynch and dug into market analysis as an economist at Analysis Group. Crunching numbers, data, and making big decisions, she got plenty of practice while working at these firms. But she wanted more than finance. Stone got hooked on data science and hands-on tech work. That passion pushed her into tech leadership, where she could actually shape products and make a difference for users.

Climbing up the career ladder

Her first big leap into tech started at Nuna, a healthcare tech company where she was Chief Operating Officer (COO). There, she drove projects that relied on data to improve real-world outcomes. Then at Lyft, she became Vice President (VP) of Science, leading teams that blended data science, machine learning, and user behavior.

Netflix brought her on board in 2020 to run its Data and Insights team. What exactly was Stone’s job there? In layman’s terms, she had to turn mountains of data into smart moves that make the service better for viewers. Stone played a big role in building out recommendation systems, figuring out what people want to watch, and giving the OTT giant the tools to make sharper business calls.

Stone’s hustle bore fruits and by October 2023, the OTT giant promoted her to Chief Technology Officer (CTO). Notably, she was the first person to ever wear that title at the company. So, in a way, it wasn’t the position she was hired into — rather, in Sherlock’s words, she “invented the job.”

Currently, Stone runs all things tech: data, engineering, research, and a massive team working around the clock to keep the OTT platform fast, reliable, and innovative. It’s more than managing gadgets and code. In fact, Stone has become a key voice in steering the platform’s future, which includes improving streaming quality, sharpening those recommendation engines, and weaving AI and machine learning into the whole experience so people actually find shows they love.

Stone’s job description hasn’t really stopped at being just the CTO of the company. Recently, the streaming company handed her even more responsibility, making her Chief Product and Technology Officer. So now, she also leads the teams behind the features and experiences viewers see every day.

Stone’s contribution and impact

In case you ask, what Stone has done and achieved so far — here’s a rundown:

First, there’s OTT’s obsession with data — Stone put that front and center. The team she leads has turned machine learning and analytics into a core part of how the OTT platform operates. Those “you might like this” recommendations? They’re not just smoke and mirrors — they keep over 300 million people hooked, and that’s a big deal in a world where every streaming service is fighting for your time.

But, she’s not just keeping the lights on, either. Stone is out in front, pushing the streaming company into new tech territory. Live streaming is another beast, and Stone’s running point there, too. Her teams are building the tech to handle live sports, massive events, and interactive shows — stuff that can bring in millions of viewers all at once. Pulling that off takes real vision and a lot of nerve. It’s not only the nonstop hustle; what really matters are the results you can see.
