Cincinnati-based, solely run

EvDev Studios, LLC is owned and managed by Evin Lodder. It was registered in Ohio in 2026 to put a proper company behind software that was already being built.

The studio does the whole job rather than a slice of it: design, client, server, database, deployment, monitoring and support. That is a deliberate constraint. Owning every layer means a bug report can be traced from the screen it happened on down to the query that caused it, and with maximum system knowledge.

Our first product is House Rules Cards, a set of classic card games where each table can play by its own house rules. It came from a specific annoyance: every online version of Euchre plays one canonical version of the game, and almost nobody plays that version at home.
