What Synthesia is
Synthesia is an AI avatars tool in the B2B go-to-market stack. In the vendor's own words: “#1 AI Video Generator.” Put plainly, a tool in this category generates a presenter so video outreach scales past what a person can record.
Where it sits in an outbound stack
Most outbound stacks are four layers: the data that decides who you talk to, the channel that carries the message, the writing that earns a reply, and the system of record that remembers what happened. Synthesia sits in the AI avatars layer. Tools beside it are worth comparing on coverage and price; tools in the other layers are worth wiring to it rather than replacing it with.
Using Synthesia with M for Mercury
Synthesia covers a slice of go-to-market that sits next to outbound rather than inside it. Mercury handles the LinkedIn half: audience, journey, message, pacing across senders, and one inbox for every reply. Where the two meet is usually the hand-off — Mercury pushes contacts and events out over webhooks, Zapier, Make, n8n or its own API, so a warm reply can trigger whatever Synthesia is set up to do next.
