CorrespondHub
A private correspondence platform letting creators and public figures monetize direct access: paid messaging, document review, meeting requests, and a marketplace — built end to end.
Custom platforms, web apps, integrations, and internal tools, designed and shipped by the people who write the code.
No service menu, no upsells. Engagements are scoped per project and run as a fixed-price build or a monthly retainer, with direct access to the founding team. Often that means we build the product another company ships under its own name — our code, their brand.
