Android Engineer, Clerk

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.
