Now another startup is announcing a massive round of funding for a platform that it believes has its own unique role to play in disrupting enterprise IT: by providing a single, all-in-one solution covering various aspects of workplace productivity. ClickUp, which provides set of tools that lets its users tackle project management, document collaboration, spreadsheets, chat, and goals from a single platform — a little like Workday but for productivity — has raised $400 million, a Series C funding that the company confirmed values it at $4 billion post-money. Craft Ventures and Georgian Partners are among its earlier backers; the company has now raised $535 million. The company counts the likes of Google (yes, the company behind its own productivity tools), McDonalds, Booking.com, and Netflix among its large enterprise customers. In all, ClickUp is being used by 800,000 teams — up from just 200,000 a year ago.A significant proportion of ClickUp’s customers, some 40%, are already based outside of the U.S, with a large part of those users in Europe — some 275,000 teams in all, the company said — hence its interest in focusing more deeply in the region. It will also include localised versions of its platform for France, Germany and Spain, the company said. ClickUp said that this is, to date, the single-largest Series C in the workplace productivity market (others like Slack have raised bigger single rounds… so still room to grow!). Andreessen Horowitz and Tiger Global are co-leading the round, with Lightspeed Venture Partners and Meritech Capital Partners also participating. “ClickUp is synonymous with the future of work, and we’re thrilled to partner with a company that has shown such a strong commitment to its users and product.
