Michelle Zatlyn Net Worth

Michelle Zatlyn has an estimated net worth of $3.1 billion, according to Forbes Real-Time Billionaires, Michelle Zatlyn profile (figures as of October 20, 2026). That is up from $1.2 billion in 2024.

Michelle Zatlyn is a Canadian tech executive best known as the cofounder, president, and chief operating officer of Cloudflare. She helped start the internet infrastructure and cybersecurity company in 2009 with Harvard Business School classmates Matthew Prince and Lee Holloway. Before that, she worked as a product manager at Toshiba and joined the founding team of the Canadian rewards company Achievers. She also serves on Cloudflare’s board and joined Atlassian’s board in 2021.

Her wealth is tied mainly to Cloudflare, which went public in 2019. Forbes says her fortune comes from cybersecurity, and the company had annual revenue of $2.2 billion in 2025. Forbes also says she owns around 2% of Cloudflare’s stock. Zatlyn stands out in the sector because she is the only female founder running a public infrastructure company today. Forbes valued her at $3.1 billion on its real-time billionaires tracker as of October 20, 2026.

How Michelle Zatlyn built her fortune

Zatlyn’s money comes mostly from the company she helped create. In 2009, she cofounded Cloudflare after meeting Matthew Prince at Harvard Business School. The business focuses on internet infrastructure and security, placing her in the technology industry and the cybersecurity field. As president and chief operating officer, she has stayed in a top leadership role while the company grew from a startup into a public company with a global reach.

Her earlier jobs helped shape that path. She spent time as a product manager at Toshiba and was part of the founding team at Achievers, a Canadian employee rewards firm. Forbes says she owns around 2% of Cloudflare’s stock, which is a key reason her wealth rose as the company expanded. Cloudflare’s 2019 stock market debut and its $2.2 billion in annual revenue in 2025 are central pieces of that story.

What Forbes says about her net worth

Forbes estimated Zatlyn’s net worth at $1.2 billion on the World’s Billionaires List in 2024, then $1.6 billion in 2025, and $2 billion in 2026. Those gains line up with Cloudflare’s growth as a public company and with her continuing ownership stake. Because Forbes classifies her as self-made, those estimates track wealth she built through her business career rather than through inheritance.

By October 2026, Forbes put her at $3.1 billion on its real-time billionaires tracker. That figure is much higher than the annual list estimate from earlier in 2026. The main drivers named in the public record are clear: her Cloudflare stake, the company’s place in internet security and infrastructure, and its scale as a public business. Forbes also notes that she sits on the board of Atlassian.
