ClickUp

ClickUp is a rapidly growing all-in-one productivity platform that aims to replace multiple workplace tools by integrating task management, documents, chat, goals, and automation into a single unified workspace. Founded in 2017 by Zeb Evans and Alex Yurkowski in San Diego, California, ClickUp was born from the founders' frustration with using 15 different productivity tools across their previous marketing company.

What started as an internal tool quickly gained traction, and ClickUp has grown from its first paying customer in November 2017 to over 100,000 paying customers and 20 million users worldwide by 2025. The company achieved unicorn status in October 2021 with a $4 billion valuation after raising $400 million in Series C funding led by Andreessen Horowitz and Tiger Global.

ClickUp has experienced remarkable revenue growth, reaching $300 million in annual recurring revenue in 2025, up from just $1 million in 2018. The platform serves notable enterprise customers including Google, McDonald's, Booking.com, and Netflix. In 2025, ClickUp launched ClickUp 4.0, a major redesign featuring dual AI agents (ClickUp Brain and Communication Channel Agent) that position the company to compete directly with Slack, Notion, and Microsoft Teams. With 400% growth in AI sales and over 800,000 monthly team signups, ClickUp continues to innovate aggressively while planning an IPO within two years. The company's mission remains focused on making the world more productive by consolidating the fragmented productivity tool landscape into one powerful, customizable platform.
