A network for professionals, anywhere. Hosted in the EU, owned by you.
MainDeck helps you build a chronological feed from people, topics, and Decks you choose. It runs on EU-sovereign infrastructure, profiles are private from the public web by default, and discovery stays transparent.
Build a feed around people and topics you choose
Follow people, join Decks, and shape a timeline that reflects your own professional interests.
Join Decks for teams, topics, and communities
Decks create a shared space around a subject today, with richer collaboration features planned as MainDeck grows.
Discover beyond the suggestions
Suggestions are personalised, but search stays broader so you can explore and shape your own graph.
Use tags to shape discovery
Tags connect posts to topics people choose to follow, helping the right network find what matters without hidden ranking.
Privacy by default
Profiles start visible to signed-in members, not the open web.
Current trust controls
Read how MainDeck handles EU hosting, privacy defaults, and the safeguards that are in place today.
Latest is really latest
Posts appear newest first. No invisible scoring, no engagement bait, no feed tuned to keep you scrolling.
Trending is labelled and bounded
Trending uses transparent engagement thresholds in a recent window, so it stays understandable instead of opaque.
EU sovereignty
Core services stay on European infrastructure, with public trust and privacy pages that explain the current setup plainly.
Transparent discovery
Suggestions are explained, and search lets you go beyond them instead of trapping you inside a ranking loop.
Topic-driven discovery
Follow topics, use tags on posts, and build a feed around the subjects you actually want to keep up with.
Clear user control
Visibility settings, feed behaviour, export, and deletion are designed to be understandable.
A calmer professional graph
MainDeck is built for professional signal, not for surveillance metrics or performative algorithm theatre.
