3Play Media

3Play Media is a media accessibility and localization company headquartered in Boston, Massachusetts, founded by four MIT graduate students, including co-founders Josh Miller and Chris Antunes, researching affordable ways to make video content accessible. The company provides closed captioning, transcription, audio description, subtitling, translation/localization, interactive transcripts, and video search tools. Per its own materials, 3Play Media serves more than 2,000–10,000 customers (figures vary by source and year) across higher education, media and entertainment, government, enterprise, and sports sectors, and has recently launched AI-enabled video accessibility tools aimed at helping institutions comply with expanded ADA Title II regulations ahead of a 2026 enforcement deadline. The company also introduced "Pulse," a platform for auditing, scoring, and remediating video libraries for accessibility compliance at scale.

Verification notes: founding-year sources disagree between 2007 and 2008 (Wikipedia, ZoomInfo, HR.com, ContactOut, and RocketReach cite 2007; LinkedIn, LeadIQ, and Seamless.AI cite 2008) — treat as unresolved and confirm directly before publishing. Employee counts vary widely by source and date (ContactOut: 555; RocketReach: 593; LeadIQ: ~585 as of April 2026; PitchBook: 482; Seamless.AI: 1,001–5,000 range); the roughly 500–600 range is the most consistent estimate — confirm current count directly before publishing.
