Sable secured $45 million in funding from Sequoia to develop an AI designed to conduct product demonstrations without the need for human involvement.

      Sable has secured $45 million from Sequoia Capital and 8VC to create an AI system named Aidan, designed to conduct live product demonstrations, provide real-time responses to customer inquiries, and seamlessly switch languages during conversations. Founded less than a year ago, Sable positions Aidan as an AI team member intended to supplant not only chat support but also the entire demo-to-onboarding process. Fortune exclusively covered this funding news on Wednesday.

      In contrast to chat widgets commonly found on websites, Aidan operates in a shared browser window, actively engaging with the product as the buyer watches and interacts. Sable enhances the AI's capabilities by inputting recordings of the company's top sales calls, along with internal documents and marketing content, effectively creating a reusable knowledge base for each client. CEO Nim Ravid maintains that Aidan offers a more human-like experience than traditional scripted bots, as it can detect page modifications and adapt its presentation in real-time.

      Notion and Decagon, an AI customer service startup, have already implemented Aidan in their operations. This strategy resembles the AI sales agent Jamie developed by BCG, which learns from a firm’s top and bottom performers, though Sable focuses on customer-facing roles rather than internal training. Sable asserts that Aidan can fulfill four human functions simultaneously: sales development, demo specialist, solutions engineer, and customer-success onboarding.

      Sequoia partner Shaun Maguire stated that the demo reminded him of Stripe's impact on the payments industry, after witnessing Aidan switch between English, Mandarin, and Spanish while guiding a buyer through a product. Joe Lonsdale, co-founder of Palantir and founder of 8VC, joins Maguire on the company’s board. Noteworthy angel investors include HubSpot co-founders Brian Halligan and Dharmesh Shah, Antonio Gracias from Valor, and Scott Wu, CEO of Cognition.

      This funding comes as the agentic AI sector, which encompasses software capable of executing tasks beyond simple text generation, is projected to reach approximately $9 billion to $10 billion globally by 2026, with estimates soaring to $57 billion by 2031, according to Mordor Intelligence and Coherent Market Insights. Earlier this year, Sequoia raised $7 billion for its largest late-stage fund, emphasizing AI as a key focus under new leadership. Sable aligns with this strategy, betting that interactive AI can bridge the gap between product capabilities and buyer understanding.

      The challenge remains whether Aidan can navigate the skepticism fostered by years of subpar chatbots, an issue Ravid himself acknowledges. Trust, potential job displacement, and competition from platforms like Notion’s own AI agents are significant hurdles for a company urging enterprise clients to entrust their sales processes to technology. Being less than a year old, Sable faces the substantial challenge of transforming a persuasive demo into a product that can consistently replace human sales engineers at scale—an endeavor many AI startups have promised but few have successfully realized.
