Executive Summary

Christopher (Chris) Antunes is co-founder and co-CEO of 3Play Media, the Boston company that provides captioning, transcription, audio description, translation and subtitling for video. He shares the chief executive role with his co-founder Josh Miller: Antunes leads operations and product, and Miller the go-to-market teams. He has been with the company since its earliest stage — its first SEC filings in 2010 already list him as an executive officer and director — and co-led its 2022 acquisition of Captionmax, which took 3Play into live captioning at scale and into Canada.

Professional Journey

3Play Media was incorporated in Delaware in 2007, with Antunes and Josh Miller as its founders. Its proposition, as Antunes put it in 2022, was “a proprietary platform marrying technology with people”: software and speech technology doing the bulk of the transcription work, with human editors bringing the output up to the accuracy that accessibility compliance requires. The company’s early filings show a small, seed-funded business — a Form D in February 2010 recorded an offering of $600,000, and another in June 2011 a round of just over $500,000 — with Antunes listed both times as an executive officer and a director.

3Play has since grown into a broader accessibility and localization provider. Its largest step came in February 2022, when it acquired Captionmax, a Minneapolis company founded in 1993 with offices in Los Angeles, New York and Calgary, and with it National Captioning Canada. The deal, announced while 3Play was a portfolio company of Riverside Partners, extended 3Play’s footprint across North America and accelerated its recent move into live captioning; Captionmax and NCC were later brought under the 3Play brand.

Antunes and Miller run the company as co-CEOs. The company describes Antunes as having led operations and product development since 2008, and today frames his work around combining AI automation and tooling with a global marketplace of language experts — the same technology-plus-people model on which 3Play was founded. The wider leadership team includes Chief Financial Officer Steve Nee and Chief Technology Officer Dan Caddigan.

Outside work, 3Play describes him as a competitive distance runner.
