The engine wealth software runs on.
Worthune exists because every wealth platform ends up rebuilding the same financial engine, and none of them should have to.
What we build
Worthune is a headless platform for wealth software. Unified household management keeps every client’s accounts, plans and decisions current and coordinated, and puts the whole picture in front of clients and advisors under our customer’s brand. A full planning engine and a catalog of verified calculators run on the same API. Customers integrate once, over REST, MCP, SDKs or embeds, and ship in weeks.
How we work
Every model is written to a published specification. Before it ships, a second implementation built from that specification alone has to agree with the production engine on hundreds of cases, and a disagreement stops the release. Government figures, such as IRS limits, tax brackets and Social Security factors, are kept in a registry with their primary source and the date a person last checked them. When a model changes, the change is versioned and written down in a public changelog. Every answer carries a record that can be recomputed later. The methodology page has the full method, and every specification is readable at worthune.com/models.
Who builds it
Worthune is built by founders who have spent their careers where finance and technology meet: building fintech products, consulting for Fortune 100 financial institutions, and designing AI-enabled services. That work left one conviction, that financial software earns trust with math that can be checked, not with promises.
The rules we keep
- ✦We compute; we do not advise. Every decision surface shows the alternatives, and every output is a planning illustration, not a recommendation.
- ✦We carry no market view. Return assumptions are the customer's, or labeled illustrative defaults until they supply their own.
- ✦We never change a number silently. Behavior moves only with a version bump and an entry in the public changelog.
- ✦We sell no financial products. No affiliate links, no sponsored calculators, no revenue from what a household decides.
- ✦We write for adults. Plain language, stated limitations, no anxiety headlines.
