While most startups chase venture capital, Mailchimp became one of the largest bootstrapped tech companies in the world. In 2021, it sold to Intuit for $12 billion, all without raising a single round of funding.
Here’s how they did it.
The Origin: Born as a Side Project
Mailchimp wasn’t even supposed to be a startup.
Founders Ben Chestnut and Dan Kurzius were running a web design agency.
In 2001, clients kept asking for help with email marketing.
Instead of building campaigns for each client, they built a tool that let clients do it themselves.
That tool became Mailchimp.
No VC, No Problem
From day one:
Mailchimp was funded entirely through revenue from customers.
No outside investors. No board. No pressure to grow unsustainably.
They focused on sustainable growth, customer feedback, and long-term trust.
Ben and Dan rejected VC money because they wanted to retain control and build on their own terms.
The Big Shift: Freemium Magic
In 2009, Mailchimp made one major move that changed everything:
They introduced a free plan.
That led to:
A massive spike in users (from 85K to 450K in a year)
Viral growth via word of mouth
Lower CAC due to organic adoption
This single decision made Mailchimp the default email marketing tool for startups and SMBs.
