Synthesia launches AI roleplay coach for employee training, moving beyond passive videos

Synthesia introduced Roleplay Sessions on Wednesday, an interactive training product where employees practice high-stakes conversations with an AI avatar that responds, challenges, and evaluates their performance against a rubric. The move marks the British AI startup's pivot from video generation toward performance management and measurable behavioral change.

The new offering targets sales training and leadership development, with early commercial rollouts already underway at three major customers: one of Europe's top three companies by market cap, a Fortune 100 firm, and a leading global recruitment company, according to Synthesia.

Roleplay addresses a fundamental gap in corporate training. Research cited by Synthesia shows that most training—including video-based programs—informs and demonstrates but often fails to change actual behavior. "Video performs way better than text or sending out a document," CEO Victor Riparbelli said in an interview. "But for most things, we learn the best by actually practicing something rather than just reading it."

The platform captures granular performance data as employees practice, allowing managers to assess workforce capabilities in ways previously difficult to measure. "If you have your entire sales team practice with an AI role player, you can get very granular data on how your sales force is doing overall," Riparbelli explained.

Roleplay is Synthesia's first release under a broader "Sessions" platform the company plans to expand into job interviews and candidate screening. Customers can build their own training programs or work with Synthesia's consultants to create custom solutions tailored to their existing materials and context.

The launch reflects a broader shift in enterprise AI adoption. Companies are moving beyond flashy AI demonstrations toward tangible business outcomes and measurable impact. As Riparbelli noted, the focus is increasingly on whether AI "generates measurable business outcomes" rather than whether it looks compelling in marketing demos.

Currently an enterprise product, Roleplay will expand to small businesses, prosumers, and educational institutions over the coming months as inference costs decline.

Synthesia's move also strengthens its competitive position. While the company's avatar and voice technology remain proprietary, its reasoning intelligence relies on OpenAI's models. By layering rubrics, performance analytics, and talent mapping onto this foundation, Synthesia positions itself less as an avatar vendor and more as a performance-management platform—a harder moat to replicate than content generation alone.
