This is the real Ostly OST — the one we use to build Ostly. Click any node to read it.
Why OSTs?
Opportunity Solution Trees give your team a shared visual map from business outcomes to customer problems to potential solutions. They make your thinking explicit, reduce wasted work, and keep discovery honest.
Every opportunity and solution traces back to a desired outcome. No more building features disconnected from business goals.
Visualise your product thinking in one place. New team members get context fast. Stakeholders see the logic, not just the output.
Know which opportunities are worth pursuing before you invest in solutions. Run smaller experiments that inform bigger bets.
How it works
Ostly keeps the structure simple so you can focus on the thinking, not the tool.
Start with the metric or business goal you want to move. This becomes the root of your tree.
Add the customer problems or needs that could drive your outcome. Interview-backed, not assumed.
Attach potential solutions to specific opportunities. Keep them distinct — each solution serves one opportunity.
Plan the smallest test that would validate or invalidate a specific assumption before you build.
Features
The features that matter for good discovery work. Nothing that gets in the way of it.
Drag, drop, and rearrange nodes freely. Auto-layout arranges your tree hierarchically with one click.
Outcomes, opportunities, solutions, and assumption tests each have distinct colours so your tree is scannable at a glance.
Generate a shareable link for any OST. Stakeholders can view without needing an account.
Organise multiple OSTs across products, teams, or time periods. Keep your discovery work tidy.
Working on a big tree? Collapse branches you're not focused on to reduce visual noise.
Mark opportunities and solutions as parked or done to track progress without deleting work.
Connect Claude Desktop or Cursor to your workspace. Your AI can read your tree and add nodes directly — no copy-pasting between tools.
Works with your AI tools
Ostly includes an open MCP server. Connect Claude Desktop, Cursor, or any MCP-compatible AI tool to your workspace. Unlike closed AI co-pilots, your AI can pull context from Notion, Linear, or anywhere else — and write it straight into your OST.
Other tools bundle AI as a proprietary add-on. Ostly exposes an open MCP server — your AI, your choice of tool.
Your AI talks to Notion, Linear, and Mixpanel independently. It reads your interviews, finds the opportunity, and adds it to your OST.
No manual copy-paste between tools. Your tree reflects what your AI is learning across your stack in real time.
