Synthesia hits $4B valuation after $200M funding led by Alphabet and Nvidia

AI video startup Synthesia just pulled in one of the largest private rounds in Europe’s AI sector this year, signaling how aggressively Big Tech continues to place long-term bets on enterprise AI. The London-based company raised $200 million at a $4 billion valuation, nearly doubling its price tag from a year ago and cementing its position as one of the UK’s most valuable private tech firms.

The round was led by Alphabet’s growth fund GV, with backing from Nvidia’s NVentures, Accel, New Enterprise Associates, Hedosophia, Evantic, and Air Street Capital. The deal follows Synthesia’s $180 million raise in 2025, when the company was valued at $2.1 billion. Investor appetite has only intensified since then as demand for AI-generated video accelerates inside large organizations.

“The round sees Synthesia hit a $4 billion valuation and was led by Alphabet’s GV, with participation from Evantic, Hedosophia, Nvidia’s NVentures, Accel, New Enterprise Associates (NEA) and Air Street Capital. It nearly doubles the price tag the startup hit a year ago, when it picked up $180 million in funding, and a valuation of $2.1 billion,” CNBC reported.

Founded in 2017, Synthesia builds AI video tools used by enterprises for training, internal updates, and customer-facing communication. Companies rely on the platform to create videos without cameras, studios, or production crews, replacing traditional content workflows with AI-generated presenters and scripted outputs.

Chief executive Victor Riparbelli framed the funding as a scale move rather than a pivot. “The funding round was ‘about scaling’ its vision of AI reducing the cost of content creation,” he said, pointing to AI video as “a better, more engaging way for organizations to communicate and learn.”

Riparbelli tied the company’s momentum to changes happening inside large businesses. “We see a rare convergence of two major shifts: a technology shift with AI Agents becoming more capable, and a market shift where upskilling and internal knowledge sharing have become board-level priorities,” he said.

The financing includes a secondary share sale for employees, structured in partnership with Nasdaq and priced at the same $4 billion valuation. The move gives long-time staff a chance to realize liquidity as the company continues to scale without heading toward public markets just yet.

Synthesia plans to deepen its presence in interactive video experiences powered by agentic AI. The new capabilities allow viewers to engage with videos in real time, ask questions, explore scenarios through role-play, and receive dynamic responses, rather than simply watching static training modules.

The funding lands during a historic stretch for AI investment on both sides of the Atlantic. European AI startups raised $21.4 billion in private funding during 2025, according to Dealroom, setting a regional record. U.S. AI companies brought in $162.7 billion over the same period, though roughly $70 billion of that total came from just three firms: OpenAI, Anthropic, and xAI.

Momentum has carried into 2026. CNBC recently reported that OpenAI is in talks with Middle Eastern sovereign wealth funds for a round that could reach $50 billion. Anthropic signed a term sheet for a $10 billion raise, and xAI closed a $20 billion round, underscoring how capital continues to concentrate around AI infrastructure and deployment leaders.

Synthesia’s growth metrics put it firmly in that conversation. The company has reached $150 million in annual recurring revenue and expects to cross $200 million sometime in 2026, chief financial officer Daniel Kim told CNBC. That trajectory places Synthesia among a small group of European AI startups operating at meaningful enterprise scale.

The round comes less than a year after Adobe took a stake in Synthesia following the company’s move past $100 million in annual recurring revenue. In April 2025, TechStartups reported that the two companies had entered what they described as a “strategic” partnership. Financial terms were not disclosed, and neither company has shared details about the commercial structure of the deal.

The company’s rise has drawn attention beyond venture capital circles. UK political leaders have publicly embraced Synthesia as a domestic success story. London Mayor Sadiq Khan and then–Tech Minister Peter Kyle attended the opening of its new office last summer.

UK Chancellor of the Exchequer Rachel Reeves echoed that support. “Synthesia is a UK success story, creating new jobs and opportunities in this country,” she said. “It shows that by backing innovators to start, scale and stay in the UK through better access to finance and generous tax reliefs, we can turn the promise of AI into better-paid jobs and long-term growth across the UK.”

For investors like Alphabet and Nvidia, the deal reflects a broader strategy: backing application-layer companies that turn foundational AI advances into everyday enterprise tools. For Synthesia, the fresh capital buys time, scale, and a wider runway to shape how video becomes part of daily work across global organizations.
