Synthesia, the London‑based AI video platform, is doubling its workforce by hiring 400 people and opening new offices in Austin, Paris and Berlin. The move follows a $200 million Series E led by Google Ventures that valued the company at $4 billion. With a current team of over 600, the firm plans a 70 % head‑count increase this year.

The expansion targets key European and U.S. markets where Synthesia’s avatar‑based video software already serves big names like Merck, Orange and Zoom. By investing over $25 million in new hubs, the company will focus on go‑to‑market and customer‑success roles to support contracts worth more than $100 k, which have tripled in the past year and through the next year growth strategy today.

With offices now in London, New York, Copenhagen, Amsterdam, Munich, Zurich, and the new locations, Synthesia aims to cement its presence across the DACH region and the U.S. The 70 % hiring push signals confidence in reaching $200 million in annual recurring revenue by 2026 and solidifies its role as a leading AI‑video provider for enterprise communications in the global market in 2026.
