TRMNL is an electronics start-up founded by Ryan Kulp in October 2023. It began on Kickstarter where it received $157,677 in public backing out of a $5,000 goal. Their sole product offering is a customizable e-ink display which is marketed as being developer-friendly with no subscription fees. The company provides publicly accessible guidance on DIY building a similar device and using TRMNL's API. They also claim to not collect any data that is personally identifiable to their users.

TRMNL offers users four methods of building their display:

1. Default - buy TRMNL device, that runs TRMNL firmware, and pings TRMNL server
2. BYOD - build user's own device, that runs TRMNL firmware, and pings TRMNL server
   • This option requires that users pay "a small monthly fee to cover [the user's] compute time on [TRMNL's] servers, since [TRMNL doesn't] make any revenue on a device sale."
3. BYOD/S - build user's own device, mod TRMNL firmware, and ping the user's own server
4. BYOS - buy TRMNL device, mod TRMNL firmware, and ping the user's own server
