Addressable-spend model. We size the market by estimated capacity-building spend, not nonprofit count alone.
Method. Reachable nonprofit operating base × 4–7% capacity-building allocation.
Ventura County beachhead. Applying that range to the reachable small/mid-sized nonprofit base produces ~$8–12M in annual addressable spend.
Expansion logic. The same method scales to adjacent nonprofit ecosystems and HSI campuses: SAM = ~$120–180M/yr; TAM = ~$1.6–2.4B/yr.
Year-1 SOM. Target ≤ $250K from Beachhead — approximately 2–3% of addressable Ventura County capacity-building spend.
