Sable builds Aidan, an AI employee that runs live, interactive product demonstrations and sales calls on behalf of B2B software companies. Unlike chatbots or pre-recorded demo tools, Aidan operates inside a shared browser window — seeing the buyer's screen, clicking through the actual product, speaking naturally, and adapting in real time to questions and objections. It can switch languages mid-conversation without human intervention. Aidan is trained on a company's best sales call recordings, internal documentation, and marketing materials. This knowledge is organized into what Sable calls the "Brain" — a self-improving context graph that gets smarter after each conversation by identifying knowledge gaps and capturing successful interaction patterns. Deployment requires no technical integration. The product targets B2B SaaS companies where sales engineers are a bottleneck: demos on demand, onboarding walkthroughs, feature launches, and multilingual buyer calls. Sable's pitch is that Aidan absorbs four human roles at once — SDR, demo specialist, solutions engineer, and customer-success onboarding. Founded in October 2025 by four Harvard graduates, it came out of stealth in July 2026 with Notion and Decagon already live in production.
