We're a small team (<20) and have seen consistent customer growth since January. We build drop-in auth components for React and corresponding hooks so developers can design their own. Going forward, we've noticed that the last generation of developer tools have failed to embrace React, so we're building a unified platform of components and hooks. Since we manage authentication, we can safely expose other devtools directly to the frontend. A proof of concept for this is our use-stripe-subscription, where we allow users to purchase and manage their own subscription through a useSubscription() hook.
