British AI Startup Synthesia Doubles Valuation to $4 Billion With Nvidia, Google Backing

LONDON: AI video startup Synthesia raised $200 million in Series E funding at a $4 billion valuation, nearly doubling its worth from $2.1 billion achieved just one year ago.

The round was led by Alphabet’s GV with participation from Nvidia’s NVentures, Accel, New Enterprise Associates, Kleiner Perkins, Air Street Capital, and PSP Growth. New investors Evantic Capital and Hedosophia also joined.

Founded in 2017, Synthesia creates AI-generated video avatars for corporate training and communications. The London-based company serves over 70 percent of Fortune 100 firms including Bosch, Merck, SAP, and Heineken.

The platform allows companies to generate photorealistic avatars from webcam footage paired with voice clones speaking in over 30 languages. Users can create training videos, sales materials, and internal communications without traditional production costs, cutting expenses by up to 90 percent.

Synthesia is pivoting toward interactive AI video agents that enable employees to engage with avatars through role-play scenarios and receive personalized feedback rather than passively consuming static content.

The company rejected a $3 billion acquisition offer from Adobe in 2025 and declined discussions with Meta, choosing to remain independent. Total funding now exceeds $536 million.

Alongside the funding round, Synthesia established an employee secondary share sale facilitated by Nasdaq Private Market, allowing early team members to convert equity into cash at the $4 billion valuation.
