Custom Ink is a US-based online retail company that makes custom clothing such as T-shirts and sweatshirts.
Custom Ink was launched in 1999 by former college classmates Marc Katz, Dave Christensen, and Mike Driscoll.
In November 2013, Custom Ink received $40 million from Revolution Growth, the investment fund run by Steve Case, Ted Leonsis, and Donn Davis. The investment reportedly helped the growth of two new projects: Booster and Pear. Booster was launched by Andrew Moss who rejoined Custom Ink after being one of the original CustomInk founding members.
On February 4, 2016, Custom Ink acquired the Los Angeles company Represent.com, which helps celebrities sell limited-run T-shirts and merchandise to fans and followers.
In 2019, Custom Ink's investors sold their shares for an undisclosed amount.
In 2014, Fortune and Great Place to Work ranked Custom Ink as one of their Top 100 places to work.
