Five engines. Five revenue models. Read them in one place.
Keystone monetizes the same verified module record five times — at registry, at pool, at disbursement, at insurance, and at index. Each engine has its own pricing. Here it is, in one table.
| Engine | Pricing | How it bills | Who pays |
|---|---|---|---|
| Module Registry Toll events |
$100 per module + $10 lifecycle, $5 pool, $5 disburse, $5 policy | Auto-metered at every insert / state change. No subscription. | Manufacturer or registering party |
| Capital Rail Indicative pool-grade + pre-screen analytics |
Per-pool SaaS + NRSRO / broker-dealer partner revshare | Quoted per-pool or per-issuer. Keystone provides analytics; NRSRO + broker-dealer partners handle the regulated rating and placement. | Lender / GSE / LIHTC syndicator |
| Disbursement Rail Verified-release government API |
20–30 bps per release SaaS usage fee, set per program at creation | SaaS fee in basis points × disbursement amount, visible on every audit row. Keystone verifies; existing payment rails move funds. | Government program (HUD / HFA / CDFI) |
| Insurance Rail Pricing engine for licensed MGA partners |
Per-policy SaaS or shared share of partner MGA commission | Licensed MGA partners bind policies on carrier paper. Keystone licenses the pricing engine to the MGA — flat per-policy or revshare. | MGA / specialty carrier / reinsurer |
| Modular Index Industry-grade data licensing | $12K / $36K / $120K per year | Std / Pro / Enterprise tiers. Pilot period included. | Data platform / hedge fund / institutional LP |
License the index that turns the registry into a benchmark.

Design-partner workspaces
For early adopters — manufacturers seeding their first registry, state HFAs piloting verified-release disbursement, MGAs onboarding their first quoting cohort — Keystone offers a design-partner workspace at zero platform fees for a defined evaluation period. Toll, gain-on-sale, rail fees, and MGA commissions are waived until you choose to deploy.
The trade is access: design partners get a direct line to product development, early API surface area, and a price commitment for the first 24 months of production. Slots are limited per quarter. Apply for a design-partner workspace →
