To solve user management once and for all.
Our take
Authentication is only part of the story when it comes to user management. Developers using API tools also face the complex UI and management issues of additional features like user sign-up, sign-in, and session management, to name a few. Clerk was founded to make this simpler, reducing hours of work to minutes using pre-built React components.
Clerk stands out in a market dominated by the likes of Auth0 and OneSpan with its focus on React rather than API. This taps into a growing number of developers working with Jamstack rather than trying to wrestle customers away from market incumbents - a smart move which has seen its userbase swell by five times, growing to over a million developers.
This rapid growth has attracted investors, and Clerk closed a Series B round in 2024. This funding is being used to expand the company's services into authorisation - determining a user's permissions as opposed to simply identifying them. As account security and management will continue to be a major focus for developers going forward, Clerk is well positioned to grow into a major player in this space, especially as it continues to expand its product range.
