Five engines. Five pricing models.
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. One thing in common: we never take a regulated fee.
The one-paragraph summary before the table.
Keystone charges a per-transaction usage fee at the Registry (creates the record), basis points on disbursement and insurance (visible on every release + policy record for cost transparency), per-pool subscription plus partner revenue-share on Capital Rail (never gain-on-sale on placed securities), and annual licensing tiers on the Modular Index (Standard, Pro, and Enterprise). Specific fee levels are set during the engagement conversation. No platform fee during design-partner evaluation.
Every regulated activity — credit ratings, insurance binding, securities placement, fund movement — is performed by a licensed partner, not by Keystone. See the partner-model architecture.
| Engine | Pricing | How it bills | Who pays |
|---|---|---|---|
| Module Registry Toll events |
Per-event usage fee Per module insert · smaller per-event fees on lifecycle, pool, disbursement, 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 + partner revshare on the NRSRO data-feed fee and the broker-dealer pre-screen fee. Never on gain-on-sale. | Quoted per-pool or per-issuer. Keystone provides the analytics; NRSRO + broker-dealer partners handle the regulated rating and placement, and Keystone's revshare is a share of their data-feed and pre-screen fees only. | 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 | Annual — tiered | Standard / Pro / Enterprise tiers. Pilot period included. | Data platform / hedge fund / institutional LP |

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. Registry toll, Capital Rail per-pool analytics, Disbursement Rail release fees, and shared 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 →
Enterprise + portfolio contracts
Multi-engine deployments, jurisdiction-wide programs, and portfolio- scale commitments are quoted directly. Volume discounts apply on two line items only: per-event Registry tolls and the Capital Rail per-pool analytics subscription. Capital Rail does not charge gain-on-sale on placed securities in any tier — enterprise, portfolio, or otherwise — so there is no gain-on-sale schedule to discount. The NRSRO data-feed and broker-dealer pre-screen revenue-share arrangements are set by the licensed partner's own pricing and are not part of the Callisto Bridge invoice.
