What Is Synthesia? The Enterprise AI Video Platform Used by 70% of Fortune 100
Synthesia is the leading enterprise AI video generation platform that turns text into professional training and communication videos featuring lifelike AI avatars. It is considered the business-grade alternative to HeyGen, with a reputation for enterprise security, compliance, and consistent quality that has made it the AI video tool of choice for 70% of Fortune 100 companies including Heineken, Zoom, Amazon, and BNP Paribas.
The free plan gives you 3 minutes of video per month, access to 9 AI avatars, 140+ languages, 60+ pre-built templates, and 200+ stock video clips — enough to test the platform and create a few sample videos. Paid plans start at $18/month (billed annually) and unlock unlimited videos, more avatars, and commercial rights.
Synthesia has become the industry standard for scalable corporate video — L&D teams use it to produce training videos in 10+ languages at 80% lower cost than traditional video production.
Who Made Synthesia? The Provider Behind the Tool
Synthesia is developed by Synthesia Limited, a London-based AI company founded in 2017 by Victor Riparbelli (CEO), Steffen Tjerrild, Lourdes Agapito (UCL professor), and Matthias Nießner (TU Munich professor). The company is one of the earliest deep-learning-based AI video companies and has led the enterprise segment since the market's inception.
Synthesia has raised over $157 million from investors including Nvidia, Accel, GV (Google Ventures), Kleiner Perkins, and Firstmark, at a unicorn valuation of $2.1 billion. The company's focus on ethical AI, watermarking, and consent-based avatar creation has earned it a reputation as one of the more responsible players in generative AI video.

Why Use Synthesia? The Real Benefits for Users
Synthesia's biggest strength is enterprise trust. The platform is SOC 2 Type II, GDPR, and HIPAA compliant, with avatars created only with explicit consent and content moderation that prevents deepfake misuse. For large companies that cannot afford reputational risk from AI tools, this compliance layer is why Synthesia wins over HeyGen in enterprise deals.
Avatar quality is another differentiator. The Personal Avatars (custom AI twins created from professional studio recordings) are virtually indistinguishable from real presenters — with natural gestures, eye contact, and expressions that generic stock avatars cannot match.
At 80% lower cost than traditional video production and the ability to update scripts in minutes (vs re-shooting), Synthesia has fundamentally changed how L&D teams produce and maintain training libraries.

When Should You Use Synthesia? Best Use Cases
Synthesia is ideal for enterprise and educational video at scale. Top use cases include: producing compliance and HR training videos; creating employee onboarding content; localizing training libraries into 20+ languages; generating sales enablement videos for internal teams; producing product launch announcements; building e-learning courses for universities and academies; creating customer education and how-to video libraries; producing internal communications from the CEO and leadership; and generating marketing explainer videos for websites.
It is less ideal for creative storytelling (Runway or Pika are better), short-form social media content (HeyGen's workflow is faster), individual creators on tight budgets, or anyone needing cinematic B-roll rather than talking-head presentation.
