Notion

Notion has built the world's most beloved all-in-one workspace — combining notes, wikis, databases, and project management into a single tool that 35M+ users across 200+ countries rely on for their most important work. At a $10B valuation, Notion's bottom-up go-to-market strategy (targeting individual users who then spread it organically through their organizations) has landed it inside 75% of Fortune 500 companies without a traditional enterprise sales team. Notion AI (launched 2023) was one of the fastest AI product adoptions in software history, generating $16M in revenue in its first month. The platform's 100,000+ template gallery and developer API have created a thriving ecosystem of integrations that rival platforms like Salesforce's AppExchange at a fraction of the complexity.
