Synthesia, a London-based startup specializing in AI avatar technology, has successfully raised $180 million in a Series D funding round, elevating its valuation to $2.1 billion. With 60,000 enterprise customers and over 1 million users, Synthesia is set to expand its footprint in the Asia Pacific region. The funds will be directed towards hiring and enhancing product capabilities, as CEO Victor Riparbelli emphasizes the importance of creating more realistic avatars. Notably, Synthesia has avoided acquisitions, opting instead for in-house development while leveraging third-party technologies.
