Monetization broker for a video service. Let's give Youtube a run for the money.

Hosted gaming system, card games, board games, tabletop simulator style. Maybe Minecraft java, built around self hostable servers.

E2E Encryption Communication, maybe a tightly integrated reticulum host.

Dedicated news system focused on free journalism (hard with AI and propaganda I know)

Shore up Pixelfed and Loops or Competition for them.

Some form of integrated system that ties all this stuff together, like a dashboard with all your different things. Maybe something like the homeassistant dashboard but for all your fedi services.
