}The regulatory figures it has to get right, and the customers it has to be tested against. We make both — and price each the way its data actually behaves.
Cited, current, callable.
Every U.S. tax, benefit, and planning figure your software needs — contribution limits, tax brackets, RMD divisors, IRMAA tiers, COLA, estate and gift numbers — each traced to the IRS, SSA, or CMS document it came from and kept current. Delivered by jurisdiction over a live API and MCP, so you stop hard-coding constants that go stale every January.
Realistic households. None of them real.
1,451 synthetic households across 71 archetypes — each a complete financial life: income, assets, debts, insurance, goals, and a 96-month trajectory. Calibrated to behave like a real book of business, with zero PII and no data-use agreement. Drop them into any test suite, model, demo, or compliance check. Yours to keep.
Ship planners, tax tools, and advisor platforms on numbers you can defend in an audit — not constants you re-key every January.
Ground models in cited figures over MCP, and evaluate them against deterministic truth on households that carry no customer PII.
Run Reg BI, suitability, and tax-loss-harvesting test cases against realistic households — no privacy review, no DUA, no production data.
Households are calibrated to public benchmarks, validated field by field, and carry zero PII by construction. Every Rule Set figure cites its primary source and keeps its history — so a number you shipped last quarter still holds up today.
The figures change with the tax code, so you subscribe. The corpus is static, so you own it.
Source-cited figures that stay current. Start free; upgrade for commercial rights, higher limits & point-in-time history.
Realistic synthetic households to build, train, demo, and test on — yours to keep, no subscription.
