# Cloudflare President Michelle Zatlyn Has Sold $551 Million in NET Stock Across 1,901 Transactions

> Michelle Zatlyn, co-founder and president of Cloudflare, has sold $551 million in NET stock since the company's 2019 IPO, making her one of the most prolific insider sellers in the cybersecurity sector.

Michelle Zatlyn, co-founder, president, and board co-chair of Cloudflare (NET), has sold $551 million in company stock across 1,901 insider transactions since the company's 2019 IPO. With zero career purchases and a consistently high selling cadence, Zatlyn represents one of the most systematic founder-seller profiles in the cybersecurity and cloud infrastructure sector. The Numbers Metric Value Career Sell Value $551 million Total Transactions 1,901 Last Transaction Dec 11, 2025 Career Buy Value $0 What It Means Zatlyn co-founded Cloudflare with CEO Matthew Prince in 2009 and took the company public in September 2019 at $15 per share. Since then, NET has become a market favorite among growth investors, rising to over $120 — an 8x return from IPO. Her $551 million in sales across 1,901 transactions works out to roughly one transaction every business day since the IPO, executed through a pre-arranged 10b5-1 trading plan that sells small blocks at regular intervals regardless of price. This selling pattern is textbook systematic diversification for a co-founder with the majority of their net worth concentrated in a single stock. The zero career purchases confirm that Zatlyn's entire holding originates from founding equity and compensation grants — she has never bought shares on the open market. At Cloudflare's current valuation above $40 billion, even substantial selling barely moves her ownership needle, and she retains significant influence through her dual role as president and board co-chair. What to Watch Whether Zatlyn's selling pace accelerates or decelerates at current price levels — changes in the cadence of a systematic seller often signal a plan modification Cloudflare's continued push into enterprise security and AI inference workloads, which has been the primary revenue growth driver How Zatlyn's selling compares to CEO Matthew Prince's insider activity, as coordinated changes between co-founders amplify the signal
