Dharmesh Shah, notable entrepreneur and HubSpot co-founder, has sold the premium domain os.ai to Perplexity AI, shortly after his headline-making sale of chat.com to OpenAI for over $15 million.
Introduction
Perplexity AI has recently acquired the coveted os.ai domain from Dharmesh Shah, HubSpot co-founder and serial entrepreneur. This high-profile domain transaction comes soon after Shah’s record-breaking sale of chat.com to OpenAI for over $15 million, further underscoring the escalating value of carefully curated digital assets in the AI boom
The Story Behind the Deal
- Dharmesh Shah, already known for his strategic plays in the domain market, confirmed that he sold os.ai to Perplexity AI. The sale not only cements Perplexity’s ambitions beyond AI-powered search but also made Shah a “somewhat larger shareholder” in the company, suggesting the deal was at least partly equity-based.
- The transaction surfaces as Perplexity is openly building a platform far more expansive than a traditional search engine—the very concept of an AI operating system (AI OS)
Why os.ai Matters
- Brand Power: “OS” is shorthand for “Operating System”—the foundational framework of all digital interaction—and the .ai extension directly connects it to the artificial intelligence revolution. For Perplexity, os.ai is both a strategic gateway and a major brand signal
- Market Timing: The market for AI-centric domain names is exploding, with companies seeking short, meaningful domains to define their purpose and leadership in the new era
- Previous Milestones: Shah’s previous sale of chat.com to OpenAI made headlines, not just for its eight-figure price tag, but because it aligned a powerful brand asset with a global AI leader. For Shah, the os.ai sale continues his track record of turning digital real estate into strategic equity, with “buy high-quality products, sell to visionary companies, and exchange for equity” becoming a blueprint for tech entrepreneurs
Perplexity’s Vision: From Search to AI Operating Systems
- Beyond Search: Perplexity’s CEO, Aravind Srinivas, has emphasized that the company is not just in the "search business" but the "knowledge business"—aiming to create an AI OS allowing users to automate and integrate tasks across the digital spectrum.
- Launch of Comet: The newly acquired os.ai now redirects to Comet, Perplexity’s next-generation, agentic AI browser. Built on Chromium, Comet promises a proactive, AI-powered environment that can summarize pages, book meetings, fill forms, and manage multitasking—offering a glimpse at what an AI-native OS could truly be
- Industry Perspective: Industry veterans like Jaspreet Bindra see Perplexity’s move as the beginning of a transition from traditional browsers and desktop operating systems toward “Software 3.0,” where large language models act as the underlying layer for all user interaction
- Technical Ambition: Unlike conventional operating systems, an AI OS prioritizes intelligent automation, personalized assistance, and seamless cross-platform integration. This vision demands robust data collection, security, and compatibility engineering.
