Built for the way groups actually work
One place for every group, every plan, every outing.

Chat
Conversations that stay on track.
Group chats in SoStack are built around context. Pinned details stay visible, replies keep momentum, and the conversation moves toward a decision — not away from it.
Planning
From first idea to confirmed plan.
Ideas surface naturally in conversation. SoStack keeps them organized as they turn into logistics — no switching apps, no lost context, no duplicate threads to manage.
Scheduling
A time that actually works for everyone.
Finding availability should not take longer than the event itself. Share your schedule, compare in seconds, and arrive at a confirmed time the whole group can see.
Discover
Finding something is easy. Agreeing on it is where plans fall apart.
Discover local places and events, share them directly into your group chat, and move from suggestion to confirmed plan — without leaving the conversation to do it.
Follow the venues and organizers your group cares about, and receive their updates in the same place you coordinate with friends.

Built around how groups actually behave.
Most plans fall apart not because of indecision, but because the conversation gets scattered. SoStack keeps the chat, the event, and the calendar in one structure that holds together as the group grows.
The plan your group has been talking about starts here.
Download SoStack and give your group one place to turn conversation into coordination — and coordination into a confirmed plan.
