What doesn't work
Your framing is inconsistent. You pitch 'sovereign identity' to empower individuals, but your business model relies on selling 'capacity' to governments and banks who want more control, not less. The analogy to SWIFT, a centralized cooperative, directly contradicts your decentralized-sounding pitch. You're building a centralized trust directory, not a truly sovereign system.

Biggest risk
Your entire strategy relies on being the 'neutral third party.' This neutrality is temporary. The moment you achieve critical mass, your powerful bank and government clients have every incentive to fork your directory, convert it into a non-profit cooperative they control, and cut you out entirely. Your path to becoming a utility is also your path to becoming obsolete.

Key question
If your only real asset is the temporary inability of your powerful customers to cooperate, what happens when the cost of replacing you becomes lower than the fees you charge them?
