For BaaS platforms

BaaS economics, sponsor-bank readiness — modeled in the browser, exported as AP2 mandates.

Provider comparator, embedded-lending unit economics, BIN sponsorship, programme agreements, wallet float, VRP mandates, AP2 BaaS infrastructure mandates. Six demos that walk a BaaS adopter from "which provider" all the way to "what mandate does the agent runtime read." $29B → $65B addressable, every output mandate-replayable.

Six demos sequenced the way a BaaS adoption actually unfolds.

Start with provider economics. Model the embedded-lending product. Apply to a specific cohort (the SME passport demo is the only one already live). Layer in the float revenue. Design the VRP sweep logic. Make the whole thing readable by an agent runtime via an AP2 BaaS mandate.

BaaS Provider Economics & Comparator

Compare BaaS provider unit economics — sponsor-bank costs, programme agreement terms, BIN sponsorship, regulatory passthrough. Surfaces the cost of choosing the wrong provider before the contract is signed.

Embedded Lending Unit Economics Lab

Unit economics for embedded-lending products — origination cost, default curves, capital cost, partner take-rate. The model the product team runs before the BaaS provider sees a term sheet.

Wallet Float Yield Estimator

Allocation mix (sweep / MMF / non-yielding) × rate scenario × cost stack → net yield in bps + annual revenue + revenue per active user. FDIC pass-through aware, with the Synapse-Evolve programme-failure cost framed as value-at-risk. AP2 treasury mandate output.

AP2 BaaS Infrastructure Mandate Builder

Programme-policy slots + sponsor-bank gates + BIN-tier ceilings + rail caps + handoff cadence → machine-readable AP2 mandate. Same surface used by the Agentic Runtime hub for the "Apply (BaaS)" step.

AP2BaaSProgramme Policy

The BaaS economics question is the same question every time — just with different inputs.

Sponsor-bank passthrough, programme agreement terms, BIN sponsorship tiers, float revenue under a given rate path, BaaS comparator economics — these all collapse to the same calc. Every BaaS evaluation rebuilds the spreadsheet from scratch. Every embedded-lending product team relearns origination economics. Every programme manager renegotiates VRP mandate parameters that should be the AP2 standard.

The catalog's BaaS cluster is the curated answer to that — modeled in the browser, exported as an AP2 programme-policy mandate the runtime can enforce. Six demos walk the buyer from "which provider" to "what mandate does my agent runtime read at execution time" — the last cell in the spreadsheet that always gets left out.

The cross-link demo (24) is the same surface the Agentic Runtime hub exposes — because the BaaS team's policy and the agent-runtime team's policy converge at this mandate format.

For the acquirer reader A BaaS surface that exports policy as AP2 mandates is the way a buyer plugs embedded-finance customer demand into an agentic future without rebuilding the programme-policy layer.

Seven tools underneath the BaaS demos.

The catalog's BaaS cluster (T152–T164) plus the rules-based engines (RBE-08, RBE-13). AP2-exportable, MCP-discoverable, none stateful.

See where these six demos sit in the full 259-tool chain.

The Tool Chain Composer renders the AINumbers catalog as a DAG with the 27 demos highlighted. The BaaS cluster connects upward to the agentic runtime and sideways to processors — same mandate schema across all.
