Developer Action Items
- ☐ Map where Castelion hits billion valuation sits in your stack (SDK, API key, billing, data-processing addendum).
- ☐ Hold the $13 billion figure to the primary report; do not brief a number that is not on the record.
- ☐ Hold non-urgent migrations until the integration or use-of-proceeds roadmap is public — day-one coverage is not a ship signal.
- ☐ If you are mid-contract or mid-POC, ask the vendor what changes for existing customers this quarter.
- ☐ Write the single decision this forces: stay, dual-source, or exit.
