[2][3] Custom Ink (first launched as CustomInk) was founded in 2000 by Marc Katz, the company’s CEO and Chairman, and several of his college friends.

[16] In November 2013, Custom Ink received $40 million from Revolution Growth, the investment fund run by Steve Case, Ted Leonsis, and Donn Davis.

[17] Booster[18] (later Custom Ink Fundraising) is a crowd-funding website where organizers design and sell T-shirts to raise money for different social causes.

During the 2020 coronavirus pandemic, the company saw sales drop 80% in only a few days as people stopped planning reunions or in-person gatherings of any kind.

[22] The company was forced to furlough around 75% of staff, but continued paying health insurance premiums for all, helped employees apply for unemployment benefits, and offered other support services.

[24] Sales from these ideas and a return to normal business as the pandemic began to recede, Custom Ink was able to bring back its employees by August of 2020.

Some workers were able to move to open positions at Custom Ink's Dallas facility; those who didn’t received separation packages that included three months of health benefits, job placement assistance, and between 10-20 weeks of pay dependent on tenure.

[36][37] 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.
