Sable, a startup whose AI agent conducts live product demonstrations by operating a full instance of a customer's software inside a virtual machine, has raised $45 million in a Series A round co-led by 8VC and Sequoia Capital.
The agent, named Aidan, connects with a user's screen, navigates the product interface and provides guidance in real time. A technology the company calls LiveBox runs a functional copy of the product within a virtual machine, allowing the agent to share its screen, demonstrate workflows and hand control back to the user during the session. The agent can be interrupted mid-demonstration and adjust its explanation based on what the user does next.
Underlying Aidan is what Sable calls a multimodal context graph, a system that consolidates a company's documentation, past customer interactions and operational best practices into a single knowledge base the agent draws from during each session. The agent becomes more effective as more interactions are recorded and incorporated.
Customers are using the platform for user onboarding, product demonstrations, custom agent activation and partner enablement across different geographies. More than 150 companies are on Sable's inbound waitlist, including Notion, the productivity software company, and Decagon, an AI customer support company, along with several large public companies the startup did not name.
Sable said it plans to use the capital to develop its AI capabilities and expand its market reach. The company's longer-term target is for Aidan to serve as a primary interface between businesses and their customers and between businesses and their internal agents.
