Synthesia
The AI avatar video platform used by 90% of the Fortune 100.
synthesia.io ↗Synthesia is the best evidence that AI video is a real enterprise category, not just a creator-economy curiosity. The Fortune 100 penetration is staggering — 90% of the largest US companies pay for the product — and it comes from a specific insight: enterprises don't want generalist video generation, they want reliable, on-brand, repeatable avatar-based corporate communications. For enterprise AI founders, Synthesia is the reference case for how to build a multi-billion-dollar vertical AI business on a single well-chosen use case.
What's going for them.
- 0190% of the Fortune 100 and 70% of the FTSE 100 are paying customers — penetration levels that no other generative AI company has achieved at comparable enterprise depth.
- 02Valuation doubled from $2.1B to $4B in 13 months, led by Google Ventures — explicit strategic signaling that Synthesia is the category-leading AI video platform for enterprise use cases.
- 03ARR crossed $100M in April 2025 and is tracking toward ~$200M in 2026 — the fastest-growing enterprise video company in history, outpacing Loom and Vimeo comparables at the same revenue scale.
- 04Adobe Ventures on the cap table signals the company is strategically relevant to the creative-tools incumbent — a positioning that either leads to partnership depth or to being acquired at a premium.
- 05Riparbelli has been disciplined about scope — Synthesia is specifically an avatar-video training/communication platform, not a generalist video generation tool. That focus is what enabled the enterprise penetration that Runway and Suno can't replicate.
What they built
Synthesia is an enterprise AI video platform — text-to-video with AI avatars, voice synthesis, and auto-translation across 140+ languages. The product is specifically optimized for corporate use cases (training videos, sales enablement, product documentation, internal comms) rather than creative or cinematic generation. Customers upload scripts, pick from a library of 230+ AI avatars (or create a custom avatar of their own employees), and produce studio-quality video in minutes. The product stack includes the core Studio product, Avatars API, real-time translation, and a growing Agents product line for conversational video interfaces.
How they got here
Riparbelli and three co-founders started Synthesia in London in 2017 — one of the first startups focused on AI-generated human video. The first five years were patient: building better avatar quality, expanding language coverage, and nailing enterprise deployment requirements (SSO, compliance, review workflows). The ChatGPT moment in 2022–2023 pulled generative AI into enterprise conversations, and Synthesia was one of the few companies with a working enterprise product ready to sell.
Revenue ramped sharply from 2023 onward. $50M ARR by late 2024. $100M+ by April 2025. The Series E in January 2026 was led by Google Ventures at $4B — a doubling from the previous round just 13 months earlier. The customer list has become a proof point of its own: 90% of the Fortune 100, 70% of the FTSE 100, and extensive penetration in training-heavy sectors like financial services, retail, and manufacturing.
What’s ahead
Three questions matter over the next year. First, Agents product line: Synthesia’s pivot from “make a video” to “interactive avatar that converses” expands the TAM meaningfully — think customer service, training tutors, sales enablement with real-time interaction. Second, Adobe relationship: with Adobe Ventures on the cap table, the strategic optionality includes deep partnership, distribution deal, or eventual acquisition. Third, IPO path: $200M+ ARR with 90% of Fortune 100 penetration is IPO-ready scale; the question is timing and whether a European or US listing.
Why it matters
Synthesia is the reference case for how AI video monetizes in enterprise — and one of the few AI companies where “enterprise” actually means the Fortune 100, not mid-market SaaS customers. For founders, the Synthesia pattern — pick a specific workflow (corporate training), own it, let consumer AI video tools compete elsewhere — is the playbook for winning vertical AI. For investors, Synthesia is the cleanest UK-based AI company with a credible path to $1B+ in revenue, and one of the most likely European AI IPOs in the next two years.
