Notion Empire: How a Simple Docs Tool Became an AI Operating System

Notion is no longer accurately described as a note-taking app or even a document tool. By 2026, the company itself presents Notion as an “AI workspace,” with Notion, Calendar, Mail, AI, Agents, Enterprise Search, Docs, Projects, and Connections positioned as one integrated product system. The company’s real ambition is to become the unified substrate for knowledge work, not just one more productivity app.

The core founder story is about prolonged mismatch before product-market fit. Ivan Zhao later wrote that Notion started in 2013 but did not see real traction until the 2018 launch of Notion 2.0 on Product Hunt; in the “lost years,” the team rebuilt the product four times. Sequoia’s profile adds that in 2015, Zhao and Simon Last were running out of money, laid off colleagues, and moved to Kyoto to rewrite the product from scratch. That is the decisive formation period of Notion.

Ivan Zhao is the philosophical and design center of the company. Public reporting says he immigrated from China to Canada with his mother at around age 17, studied cognitive science and art at the University of British Columbia, and was deeply influenced by Douglas Engelbart’s idea of “augmenting human intellect.” Public information on his broader family background is limited, but one fact is unusually clear: when Notion was close to collapse, his mother lent him $150,000 to keep the company alive.

Simon Last remains comparatively private, but the public record still shows the essentials: Zhao found him while Last was a student at the University of Maryland, College Park; Last dropped out to join Notion full-time; and Zhao said Last’s father was a school principal. In later interviews, Last is described as the low-profile technical force behind Notion AI, focused on primitives like relational databases, permissions, semantic search, and reliable AI systems at scale.

Akshay Kothari came from a very different path. Public profiles say he grew up in Ahmedabad, India; his parents made sacrifices to send him to school in the United States; he studied electrical engineering at Purdue and Stanford; co-founded Pulse News; sold Pulse to LinkedIn; later led product and LinkedIn India; and joined Notion in 2018. His role at Notion was to operationalize growth—sales, recruiting, finance, and scale. He later received the co-founder title, which reflects a second-stage company-building role rather than original 2013 inception.

The product itself was built around a long-term idea: ordinary people should be able to shape software, not just consume it. Zhao’s early insight came from building portfolio websites for artist friends who had taste but lacked flexible digital tools. Engelbart’s writing then gave him a larger mission. Early users, however, did not immediately want a no-code software-building environment. Notion’s great strategic move was to hide that deeper vision inside a more legible “productivity” surface—docs, wikis, tasks, and later databases.

The Kyoto reboot was followed by the 2016 Product Hunt launch, helped by early investor Naval Ravikant. Sequoia recounts how the founders orchestrated that moment to generate visibility. Product Hunt later documented that Notion 1.0 took the top monthly spot, while Notion 2.0 in 2018 became one of the site’s all-time standout launches. With 2.0, relational databases and better project-management flows turned Notion into the modern product people recognize today, and the company began charging subscription fees and turned profitable.

From 2021 onward, Notion clearly evolved from a single product into a suite. The company officially acquired Automate.io in 2021 to expand integrations; acquired Cron in 2022, which later became Notion Calendar; acquired Skiff in 2024 and launched Notion Mail in 2025; launched Notion Sites in 2024; and kept pushing deeper into AI with Notion AI, Q&A, Enterprise Search, AI Meeting Notes, and Custom Agents. This was not random expansion. It was a deliberate attempt to pull more work surfaces into one operating layer.

Capital structure is one of Notion’s most unusual strengths. Forbes India reported in 2024 that Notion had raised roughly $330 million while keeping venture capitalists off the board; it added its first outside board member, a financial auditor, only in 2022. The same report estimated that Ivan Zhao still owned at least 30% of the company. In other words, Notion scaled like a venture-backed company while preserving an unusual amount of founder control and optionality.

The major financing milestones visible in public materials are these: early seed backing from First Round and Josh Kopelman; a $50 million round at a $2 billion valuation in 2020 led by Index Ventures; a $275 million round at a $10 billion valuation in 2021 led by Coatue and Sequoia; and, in January 2026, an official private tender in which GIC joined Sequoia and Index to buy about $270 million of employee shares at an $11 billion valuation. Bloomberg later reported that Notion had also weighed a $12 billion tender scenario before the official $11 billion disclosure.

Notion’s asset base is broader than software subscriptions. Its hard assets include the core workspace, the database model, API infrastructure, connections layer, calendar, mail, sites, AI systems, and agents. Its ecosystem assets are also substantial: the official Marketplace currently displays nearly 20,000 creators, 181 consultants, 2,075 collections, and 348 categories, and explicitly invites creators to submit templates, get featured, and get paid. That means Notion now owns not just a product, but a creator-service ecosystem sitting on top of the product.

The business model has also become multilayered. Official pricing shows a free tier, a $10-per-seat Plus plan, a $20-per-seat Business plan, and custom-priced Enterprise. AI is increasingly central: Business includes stronger AI capabilities such as Notion Agent, AI Meeting Notes, and Enterprise Search; Help Center materials note that Free and Plus users only get limited AI responses, while Business and Enterprise are the core AI plans; and Custom Agents use a credits model priced at $10 per 1,000 credits after trial. Notion Sites custom domains also carry add-on pricing.

The most important strategic decisions in Notion’s history were not incremental feature launches. They were structural decisions: hiding the no-code mission inside a productivity form factor; moving to Kyoto and rewriting instead of scaling prematurely; building community-led distribution rather than depending first on enterprise sales; and making an early AI shift by launching Notion AI in private alpha in late 2022 and general availability in early 2023. Those decisions changed survival odds, growth shape, and company identity.

The headline outcomes are strong. Notion officially said it passed 100 million users in 2024. Forbes estimated it generated about $250 million of revenue in 2023 and remained profitable. In January 2026, Notion officially said that more than 50% of its ARR at the end of 2025 came from AI-enabled customers. Soon after, Ivan Zhao wrote publicly that AI already accounted for 60% of the business and that the company was cash-flow positive. These are the numbers that explain why Notion now sits closer to platform status than app status.

The main criticisms of Notion are not scandal-centered but product-centered. First, it is often considered too flexible, which means too overwhelming for ordinary users; Forbes India explicitly noted that even something as simple as a to-do list can feel intimidating because of the abundance of customization. Second, Notion has had real infrastructure strain: in 2021, viral TikTok videos created so much demand that servers were overwhelmed and product development reportedly paused for six months while the backend was reinforced. Third, trust and privacy remain ongoing questions in the AI era. Notion says data shared with AI subprocessors is contractually barred from model training, and Enterprise customers get zero-data-retention treatment with LLM providers, but this is still an area users pay close attention to—especially after the company acquired privacy-focused Skiff.

Today, Notion’s real-world influence is clear. The company is not merely a startup favorite anymore. Its official homepage prominently features OpenAI customer testimony, its leadership publicly frames Notion as the place where AI-enabled work should happen, and its 2026 tender materials tie growth acceleration directly to AI adoption and global expansion, especially in APAC. The most accurate description of Notion’s current position is this: it is trying to become the operating layer where modern knowledge work, enterprise context, and AI agents meet.

A few things remain genuinely uncertain in the public record. Ivan Zhao’s exact birth date is not consistently published. Simon Last’s background remains intentionally sparse. Notion’s exact 2026 employee count is not cleanly disclosed in the most authoritative public materials. And the role of other lesser-known early contributors is not consistently reflected in the company’s own public founder narrative. The safest conclusion is that the public history of Notion is a highly legible main storyline built around Ivan Zhao, Simon Last, and Akshay Kothari—but not a fully exhaustive founding archive.
