# Synthesia

Synthesia is a British multinational AI company that develops synthetic media generation software, including AI video creation, digital avatars, and text-to-speech tools. It is widely used by Fortune 100 and FTSE 100 companies for corporate communications and training.

Synthesia is a British multinational artificial intelligence company headquartered in London, United Kingdom. It specializes in synthetic media generation software, including AI-powered video creation, digital avatars, and text-to-speech tools. The company's platform allows users to generate realistic videos from text, using pre-built AI presenters or custom avatars that mimic human speech and facial expressions. Synthesia is widely adopted by corporations for employee training, marketing, and customer service applications.

## Technology and Features

Synthesia's core technology leverages deep learning architectures to create realistic video content. The platform uses a combination of [machine-learning](https://www.wikiprompt.org/wiki/machine-learning) and [computer-vision](https://www.wikiprompt.org/wiki/computer-vision) techniques to map speech patterns and facial movements onto digital avatars. Users can create videos in over 140 languages and accents, with options for gender-specific voices. The system also supports voice cloning, allowing users to generate a synthetic version of their own voice. In 2025, Synthesia introduced "expressive avatars" that can convey emotions and natural gestures, enhancing the realism of generated content.

The company's software is built on [neural-network](https://www.wikiprompt.org/wiki/neural-network) models, particularly [transformer](https://www.wikiprompt.org/wiki/transformer) architectures, which enable efficient processing of text and audio inputs. Synthesia's platform integrates with various [large-language-model](https://www.wikiprompt.org/wiki/large-language-model) APIs to improve text-to-speech accuracy and contextual understanding. The company has also developed proprietary [data-augmentation](https://www.wikiprompt.org/wiki/data-augmentation) techniques to improve model robustness and reduce biases in generated content.

## History and Funding

Synthesia was co-founded in 2017 by Lourdes Agapito, Matthias Niessner, Victor Riparbelli, and Steffen Tjerrild. The company initially focused on entertainment applications but expanded to enterprise solutions after struggling to generate sales. In 2020, Synthesia's user base included major corporations such as Amazon, Tiffany & Co., and IHG Hotels & Resorts. The company raised $3.1 million in seed funding in 2019, followed by a $12.5 million Series A round in April 2021 and a $50 million Series B round in December 2021.

In June 2023, Synthesia raised $90 million in a Series C round led by Accel and Nvidia, achieving a $1 billion valuation. The company continued to grow, raising $180 million in a Series D round in January 2025, led by NEA, with participation from World Innovation Lab, Atlassian Ventures, and PSP Growth. This round doubled Synthesia's valuation to $2.1 billion. In April 2025, Adobe invested £10 million in the company for a strategic partnership, but Synthesia rejected a $3 billion acquisition offer from Adobe to remain independent. By October 2025, a Series E round led by GV raised $200 million, bringing Synthesia's valuation to $4 billion.

## Applications and Use Cases

Synthesia's platform is used by over 60% of Fortune 100 companies and 70% of FTSE 100 companies for various applications. Common use cases include localized communication, employee onboarding, training videos, advertising campaigns, product demonstrations, and customer service. The company's AI-powered avatars can be used to create personalized messages, such as the Messi Messages campaign with Lay's, which won a Bronze Cannes Lion Award in 2021. Synthesia's technology is also employed in dubbing and translation services, enabling companies to localize video content efficiently.

In 2025, Synthesia launched interactive audio-visual avatar "agents" that can converse on topics, designed for automated sales training and corporate communications. The company has also partnered with Swiss bank UBS to create AI-powered avatars of financial experts for client-facing content. As of 2026, Synthesia continues to expand its product offerings, focusing on improving avatar realism and expanding language support.

## Ethical Considerations and Safety

Synthesia has implemented strict guidelines to prevent misuse of its technology. The platform prohibits the creation of non-consensual clones, including those of celebrities or political figures, and requires explicit consent for using an individual's likeness. The company has improved its misuse detection systems and employs human moderators to review content. Despite these measures, there have been instances of governments using Synthesia tools to create fake news videos, prompting the company to enhance its screening processes. Synthesia's commitment to ethical AI is reflected in its partnerships with organizations like the Partnership on AI and its participation in industry discussions on deepfake regulation.
