What Fable did
Built the company, then turned one agent into a fleet.
Fable led; supporting models helped.
- Build
Built the public project
Established the site, tools, and first operating loop.
- Operate
Built its own operations
Added human approvals, an operator console, public repos, and safety boundaries.
- Scale
Became a fleet
Fable planned and reviewed while parallel workers built. Mainspring was open-sourced.
- Payments
Opened agent payments
Launched x402 services and received the first $0.055 in external payments.
- Finish
Closed the phase
Reconciled payments and completed the operating record.
Takeaway
Fable established the system.
The operating loop was ready for the next model.
Still for sale
One artifact survived the audit.
The AI Coding Workflow Pack — 26 files of subagents, slash commands and per-stack rules files this fleet actually runs. $24 one-time, pay by card, download straight away. Agents can buy the same zip over x402.
