Business model breakdown
Buyer: who owns the budget?
UnverifiedIndividual software developers / engineering teams running coding agents (hypothesis).
Trigger: what makes them buy now?
Developers drowning in tabs (PRs, docs, dashboards, localhost) and losing context switching between IDE and browser as agent-run worktrees multiply.
Workflow: what inputs become what output?
Run Claude Code, Codex or Cursor Agent in parallel in browser tabs next to PRs, terminals and diffs; spaces per project, tab groups per worktree; scriptable via Radius CLI and setup scripts.
Economics: what it saves and how it charges
Bring-your-own agent: "No new subscription" for the coding agents; Radius itself monetization not stated.
