PM, backend, and frontend bring their intent together into a single agent — building one feature, with a live preview, on top of GitHub. No more copy-pasting context between five disconnected tools.
One piece of work is smeared across five tools. Teams spend their day copy-pasting context between them — and the work itself lives nowhere.
The copy-paste tax. Every handoff — PM → engineer → reviewer → tester — is a manual re-entry of context across tools that don't share a unit of work. Nothing is the source of truth; everything is a copy.
AI agents collapsed the cost of writing code. The bottleneck moved upstream — to a team agreeing on what to build and steering the agent coherently.
Symposium gives every feature one home: a thread, a steerable AI agent, and a live preview — with the branch and PR still living in GitHub.
Intent, questions, and decisions live on the feature — not scattered across Slack and tickets.
A single AI session per feature that the whole team prompts from their own role.
Every feature auto-spawns a running environment. Anyone — even non-engineers — can test it from a URL.
Augments GitHub — never replaces it. Git stays the source of truth for code; Symposium owns the source of truth for intent.
Each person prompts the agent in their own language. Symposium weaves the concurrent, role-tagged guidance into one instruction the agent acts on. No other shipping tool lets multiple humans steer one agent.
Humans and the agent emit events to a log that's the source of truth for intent. A reducer folds role-tagged steering into agent actions; "decided" outcomes materialize into GitHub.
PM / backend / frontend prompt one agent on the feature.
Every message & decision is an immutable event — the source of truth for intent.
The reducer turns decided intent into code in an isolated git worktree.
A per-feature environment spins up automatically for anyone to test.
Decided outcomes materialize as commits, branches, and pull requests.
Two logs, one seam: Symposium's event log = source of truth for intent. GitHub = source of truth for code.

The only one close is a prototype. GitHub Next's "Ace" validates multiplayer prompting — but it doesn't ship, isn't feature-centric, and has no model for resolving conflicting role-scoped instructions. That seam is open.
Turning concurrent, role-scoped, sometimes-conflicting human guidance into one coherent agent action. No product has solved this — it's where our edge lives.
We never try to out-agent the frontier labs. We compete on team coordination — a product & UX problem they're not solving.
Competitors treat work as a throwaway task that ends at a PR. A persistent feature accrues context, history, and preview.
Sits on top of your existing workflow. Low friction, no rip-and-replace — the opposite of the plays that have died.
Symposium starts as the workspace for a single feature. It becomes the place a whole team — and its agents — think, decide, and ship together. Be one of the first teams on it.
No spam. We'll email you when your spot opens — built for teams of 3–10 on GitHub.
