Mailchimp’s founders turned a side project into a $12 billion business without outside funding

Originating from humble beginnings, Mailchimp evolved within two decades from a small business tool to a powerhouse in the marketing industry. Launched by The Rocket Science Group’s Ben Chestnut and Dan Kurzius, it caught the attention of Intuit, who acquired it for around $12 billion in 2021. With a sharp focus on customer-centric innovation and maintaining independence, Mailchimp solidified its status as a leader in global digital marketing.
