3Play Media

3Play Media was founded in 2007 by four MIT Sloan School of Management graduates — Josh Miller, Chris Antunes, C.J. Johnson, and Jeremy Barron — who identified a gap in video accessibility workflows. The company launched in Boston as a transcription and captioning service, initially bootstrapping operations before receiving a Small Business Innovation Research grant from the National Science Foundation in 2008. Miller and Antunes continue to run the company as co-CEOs. The company operates a technology-enabled service platform that combines automated speech recognition with human editing to produce high-accuracy closed captions, transcripts, and audio descriptions. Core markets include universities needing ADA and Section 508 compliance, media companies, and corporate learning platforms. Colorado State University, the University of Washington, and MIT OpenCourseWare are among disclosed institutional clients. Deployment model is SaaS with per-minute pricing — no fund commitments, no club deals, no direct investment portfolio. In late 2017, 3Play Media secured a significant minority growth investment from Riverside Partners, a Boston-based middle-market private equity firm focused on technology and healthcare. Founders retained majority control. The company has disclosed no subsequent institutional funding rounds. Known adjacent vehicles are limited to the for-profit operating entity; there is no separate philanthropic foundation. No team headcount figure has been published publicly. Structurally, 3Play Media is a bootstrapped-to-PE-backed operating company, not a family office or asset manager. Its distinction lies in defying the typical VC-fueled growth narrative — the business reached profitability and national scale from Boston without institutional capital for a decade, built on workflow software that stitches together AI and distributed human reviewers. Succession architecture remains founder-led with PE oversight.

Frequently asked questions

Who runs 3Play Media day-to-day?

Josh Miller and Chris Antunes serve as co-CEOs, roles they have held since co-founding the company in 2007. Both are graduates of the MIT Sloan School of Management. The other co-founders, C.J. Johnson and Jeremy Barron, were also part of the founding team.

How does 3Play Media produce its transcripts — purely AI or human-in-the-loop?

3Play Media uses a hybrid process that passes video files through automated speech recognition, then routes the output to a network of human editors who review and correct the transcripts. This is the core structural differentiator from fully automated competitors and the reason the company can guarantee accuracy rates above 99%.

What verticals does 3Play Media primarily serve?

Higher education is the dominant vertical — universities use the platform to meet ADA and Section 508 compliance requirements for online course content. Media companies and corporate learning-and-development teams are the second and third largest customer segments.

Does 3Play Media operate as a family office or manage third-party capital?

No. 3Play Media is an operating company that provides transcription and captioning software. It took a minority growth investment from Riverside Partners in 2017 but does not manage LP capital, make direct investments, or function as a family office.

What is 3Play Media's funding history?

The company was bootstrapped from 2007 until its first institutional round in late 2017, when Boston-based private equity firm Riverside Partners made a minority growth investment. Founders retained majority control. Prior to that, the company used a 2008 NSF SBIR grant and operating cash flow to fund growth.
