Overview

Synthesia makes software that lets businesses create videos with AI avatars instead of cameras, actors and studios. A user types a script, chooses an avatar and a language, and the platform produces a video of a realistic presenter speaking the words. Companies use it mainly for training, internal communications, onboarding, product explainers and sales content, where they need many videos, often in many languages, and need to update them often.

Synthesia was founded in 2017 by Victor Riparbelli, the CEO, Steffen Tjerrild, and two computer vision professors, Lourdes Agapito of University College London and Matthias Niessner of the Technical University of Munich. It is headquartered in London, where it opened a new global office at Regent's Place in 2025, and has teams across Europe and the US. It has become one of the UK's most valuable AI companies.

What Synthesia's platform does

• AI avatars: a library of stock presenters, plus custom avatars that let a real executive or trainer appear in videos without filming each time.
• Languages and voices: scripts can be produced in well over a hundred languages, with translation and dubbing.
• Editing and templates: a browser-based editor with templates, screen recordings, branding and collaboration.
• Interactive and agent features: the company is building conversational AI agents for corporate learning, which can answer learners' questions rather than just presenting.

How Synthesia makes money

Synthesia sells subscriptions. Individuals and small teams pay monthly or annually for self-serve plans with limits on video minutes and features. Larger companies sign enterprise contracts with unlimited or high usage, custom avatars, security controls and integrations with learning management systems. The enterprise business is where most growth comes from; more than 90% of Fortune 100 companies use the platform, according to the company.

Revenue

Synthesia has said publicly that it passed US$100 million in annual recurring revenue in 2025. It hasn't published audited figures or a precise current number, so we treat revenue as not disclosed in the data above. Research firms have published higher estimates for later periods, but those are modelled rather than reported.

Funding history

Synthesia has raised money steadily as it grew:

• 2019 and 2021: a seed round and a Series A led by FirstMark.
• December 2021, Series B: US$50 million, with Kleiner Perkins and GV.
• June 2023, Series C: US$90 million led by Accel with Nvidia's venture arm NVentures, valuing Synthesia at US$1 billion and making it a unicorn.
• January 2025, Series D: US$180 million led by NEA at a US$2.1 billion valuation.
• April 2025: a strategic investment from Adobe alongside a partnership.
• January 2026, Series E: US$200 million led by GV at a US$4 billion valuation, with new investors Evantic and Hedosophia and existing backers including NVentures, Accel, Kleiner Perkins, NEA and others.

Reports also said Synthesia had turned down an acquisition approach from Adobe and chose to stay independent. Wikipedia lists the Series E in October 2025, while most press coverage dates the announcement to January 2026; we use the announcement date.

Responsible AI

Realistic AI avatars raise obvious concerns about deepfakes and misuse. Synthesia has made content moderation part of its pitch: it requires consent for custom avatars of real people, reviews scripts for prohibited content, and doesn't allow political, news or other sensitive uses on its platform. For enterprise buyers, these controls matter as much as video quality, because a misuse incident could create real reputational damage.

Competitive landscape

Synthesia competes with other AI video companies, such as HeyGen and Colossyan, with general video generation models from large AI labs, and with traditional video production. Voice AI companies such as ElevenLabs overlap in dubbing and audio. Synthesia's advantages are its enterprise focus, security and compliance credentials, and deep integration with corporate training workflows. Its main risk is that general-purpose video models become good enough that businesses don't need a specialised tool.

What to watch next

Watch the launch of conversational AI agents for learning, revenue milestones, expansion in the US, new partnerships with software platforms, and whether the next round or a tender offer lifts the valuation further.

Key facts at a glance

Synthesia is a London AI video company founded in 2017 by Victor Riparbelli, Steffen Tjerrild, Lourdes Agapito and Matthias Niessner. It became a unicorn in 2023, was valued at US$2.1 billion in January 2025, and raised a US$200 million Series E led by GV at a US$4 billion valuation in January 2026. More than 90% of Fortune 100 companies use its platform.

Why corporate training is a good market for AI video

Large companies produce a huge amount of training and internal video: compliance courses, product updates, onboarding for new hires, safety instructions. Traditional production is slow and expensive, and videos go out of date quickly. Global companies also need the same content in many languages. AI video changes the economics. A training team can update a script and regenerate a video in minutes, and produce dozens of language versions without re-filming. That makes the return on investment easy to show, which helps sales in large enterprises.

Valuation trajectory

Synthesia's valuation roughly doubled with each of its last three rounds: US$1 billion in 2023, US$2.1 billion in early 2025 and US$4 billion in early 2026. A pattern like this usually reflects strong revenue growth combined with investor appetite for AI. Our guide to tracking startup funding rounds explains how to record such changes consistently.

What this means if you're…

An L&D or communications leader: pilot AI video on content you update often, and check consent, security and language quality.

A founder: Synthesia shows how a research-led team can build a focused enterprise business on top of fast-moving AI.

An investor: compare the US$4 billion valuation with its disclosed revenue milestones, and watch competition from general video models.

Latest developments (October 2026)

Synthesia raised a US$200 million Series E led by GV in January 2026 at a US$4 billion valuation, nearly double its January 2025 level, according to TechCrunch. It also ran an employee share sale with Nasdaq. UCL, where co-founder Lourdes Agapito is a professor, described it as one of Britain's most valuable AI companies. Synthesia is moving from training videos to interactive AI agents for corporate learning. See our AI video generation guide.
