AI Avatar Workflow vs Infrastructure
AI talking heads growing 1024%
This is a workflow product, not just a model demo. Companies are buying AI avatar tools because they turn one script and one approved likeness into thousands of usable business videos, which matters most in repetitive jobs like onboarding, training, sales outreach, and translation. The winning products make video feel like email generation, fill in CRM or HRIS data, render personalized clips automatically, and remove the time, cost, and camera friction of filming each message.

HeyGen and Synthesia sell this as end user software for teams. A marketer, recruiter, or enablement lead types a script, picks an avatar, localizes it into many languages, and exports a finished video. That is why enterprise departments, not creators, became the first durable buyers.
-
Tavus is taking the opposite route. Instead of asking users to visit a video app, it gives developers an API so products like CRM, support, or commerce software can generate avatar videos inside existing workflows. That makes AI video a feature embedded in other SaaS products, not a destination app.

The core unlock was realism crossing a practical threshold. Tavus describes current models as realistic enough under constrained settings, and the market evidence backs that up, with HeyGen reaching $22M ARR in May 2024 and later an estimated $95M by September 2025, while Synthesia scaled to about $146M by September 2025.
From here, AI avatar video is likely to split into two layers. One layer will be workflow suites like HeyGen and Synthesia that bundle creation, editing, translation, hosting, and analytics. The other will be infrastructure players like Tavus that power avatar generation inside broader business software. As realism improves and costs fall, personalized video should become a default output of enterprise systems.
