Dan Kurzius Net Worth

Dan Kurzius has an estimated net worth of $5.6 billion, according to Forbes Real-Time Billionaires, Dan Kurzius profile (figures as of October 20, 2026). That is up from $2.1 billion in 2019.

Dan Kurzius is an American businessman best known as a cofounder of Mailchimp and its chief customer officer. Before tech, he worked as a DJ, spent time in real estate, and was also a competitive skateboarder. His path changed during the dot-com era, when Ben Chestnut hired him at Cox Interactive Media's MP3 music service. That working relationship later led to a new company focused on email marketing for small businesses.

In 2001, Kurzius and Chestnut were running a web design company when they launched what later became Mailchimp as a side project. The software drew enough paying customers that in 2007 they shifted their full attention to it. They chose to grow the business from profits instead of taking outside investment. That self-funded approach helped them keep control, and it set up the 2021 deal in which Intuit agreed to buy Mailchimp.

How Dan Kurzius built his wealth

Kurzius made his fortune through Mailchimp, an email marketing company he started with Ben Chestnut. The business began in 2001 as a sideline to their web design firm, not as a venture-backed startup. Because they avoided outside money and funded growth with profits, the founders kept ownership in their own hands. That mattered later because their wealth was tied directly to the value of the company they built over time.

Mailchimp focused on software for small businesses, and that customer base became large enough that the founders went all in by 2007. Their decision to bootstrap shaped the payoff. When Intuit announced in 2021 that it would acquire Mailchimp in a $12 billion cash and stock acquisition, Kurzius and Chestnut each owned 50% of the Atlanta-based company. Mailchimp had also reported $800 million in 2020 revenue at the time of the announcement.

Forbes net worth and the big jump

Forbes first placed Kurzius at $2.1 billion in 2019, then $2.2 billion in 2020 and $3 billion in 2021. The largest move came after Intuit announced the Mailchimp deal in 2021. Forbes later estimated him at $5 billion in 2022, followed by $4 billion in 2023 and $5.3 billion in 2024. Those swings track the value tied to the acquisition and his ownership stake in the company.

The estimate moved up again after that. Forbes put Kurzius at $5.6 billion in 2025, then $5.2 billion in 2026 on the World's Billionaires List. On Forbes' real-time billionaires tracker, he was at $5.6 billion as of October 20, 2026. Across those years, the main driver stayed the same: the wealth created from Mailchimp, a self-funded software company that grew from a side project into a major technology business.
