TL;DRSable raised $45 million from Sequoia and 8VC for Aidan, an AI that runs live product demos and replaces sales development workflows.

Sable has raised $45 million from Sequoia Capital and 8VC to build an AI system called Aidan that runs live product demonstrations, answers customer questions in real time, and switches between languages mid-conversation. The company, which is less than a year old, calls Aidan an AI employee designed to replace not just chat support but the entire demo-to-onboarding pipeline. Fortune reported the funding exclusively on Wednesday.

Unlike the chat widgets that sit in the corner of most websites, Aidan appears in a shared browser window and actively drives the product while the buyer watches and clicks alongside it. Sable trains the system by feeding it recordings of a company’s best sales calls, internal documentation, and marketing materials, building what it calls a reusable brain for each customer. CEO Nim Ravid argues that the result feels closer to a human sales engineer than a scripted bot, because the system can see changes on the page and adjust its presentation mid-conversation.

Notion and Decagon, the AI customer-service startup, are already using Aidan in production. The approach echoes what BCG has done with its AI sales agent Jamie, which learns from a firm’s best and worst sellers, though Sable is targeting the customer-facing side of the funnel rather than internal coaching. Sable’s pitch is that Aidan can absorb four human roles at once: sales development, demo specialist, solutions engineer, and customer-success onboarding.
