Introduction
What FounderSync is, who it is for, and a map of the product, from your first idea to your cap table.
FounderSync is a workspace for starting a company, built for solo founders and founding teams. It keeps the early work that usually ends up scattered across documents, spreadsheets and chat threads in one place: the idea, the product requirements, the roadmap, the tasks, the launch plan, the legal documents, the agreement between cofounders and the ownership table.
Everything you create belongs to a startup. You can belong to more than one startup and switch between them, and the people you add to a startup share its data.
Who it is for#
- Solo founders who want to turn an idea into a structured plan and a task list.
- Founding teams who want to agree on roles, equity and expectations in writing, and then keep track of who is doing what.
- Founders who work with AI tools. Agents such as Claude, Cursor and Codex can connect to your workspace and work on your behalf. See AI agents.
The main areas#
The sidebar groups the product into five parts.
| Area | Pages | What it is for |
|---|---|---|
| Overview | Overview | A dashboard with your setup progress, recent activity and next steps. |
| Build | Idea, PRD, Roadmap, Launch | Define the idea, generate product requirements, see a sprint plan, and work through a launch checklist. |
| Team | Team, Agreement, Fairness | Invite cofounders, write the cofounder agreement, and track whether real work matches it. |
| Operate | Tasks, Meetings, Analytics | Run the work: a task board with time tracking, calendar events, and charts of task and time data. |
| Company | Cap table, Vault | Model ownership, rounds and exits, and store your company documents. |
Two things sit outside the sidebar. The search box at the top (Ctrl or Cmd plus K) jumps to any page or action. The AI Cofounder panel, opened with Ctrl or Cmd plus a period, is an assistant panel inside the app.
How the pieces connect#
The pages feed each other, so it helps to work roughly in order:
- The Idea page captures the problem, customer, market and business model.
- The PRD is generated from your idea. The Roadmap is derived from the PRD, so the Roadmap page only appears in the sidebar once a PRD exists.
- Tasks turn the plan into dated, owned work.
- The Launch checklist covers what to do around release day.
- The Agreement, Fairness, Cap table and Vault cover the company side: who owns what, what was agreed, and where the paperwork lives.
You do not have to follow this order. Every page works on its own once you have a startup.
