Comparison
Worthune vs Leadfusion
Leadfusion sells interactive tools to large banks and credit unions, deployed by iframe, JavaScript, or API, and positioned around lead generation and product selection. Worthune sells the computation itself — models with published specifications, open test cases, and an audit record per run. One is a customer-acquisition suite that contains calculators; the other is a calculation layer you build on.

Side by side
Sourced facts only. Where a cell says a vendor does not publish something, that means we looked at the page named in the sources below on the date shown and it was not there — not that the answer is no.
| Worthune | Leadfusion | |
|---|---|---|
| How it is delivered | REST API, MCP server, and a one-script-tag embed | Interactive tools deployed to banking sites, landing pages, or branch intranets by iframe, embedded JavaScript, or API integration |
| Programmatic API | Yes — REST and MCP, no key required for the three sample models | Yes — API integration is offered alongside iframe and JavaScript embedding |
| Pricing model | Subscription; three models free with attribution, no per-run metering | Not stated publicly; the site routes prospects to a sales conversation or a demo |
| Entry price | Free for three models; $199/month for the full catalog | Not stated publicly |
| Published specification per calculator | Yes — three in full publicly, the rest with a subscription; every input contract public | Not verified(not checked yet) |
| Published test cases | Yes — 250 cases per model, downloadable as JSONL | Not verified(not checked yet) |
| Constants with primary sources and check dates | Yes — every constant carries a primary source and the date it was last checked | Not verified(not checked yet) |
| Per-run audit record | Yes — SHA-256 over model, spec version, inputs and outputs, returned with every run | Not verified(not checked yet) |
| Free tier | Three models, no signup and no key, attribution required | Not verified(not checked yet) |
Where Leadfusion is stronger
A conversion program, not just arithmetic
Product-comparison and decision-guidance tools, rate synchronization, and CRM handoff are a coherent customer-acquisition system, and their site reports long-standing relationships with a substantial share of top-tier US banks and credit unions. If the goal is measured lead flow from a banking site, that whole apparatus is the product and we do not sell it.
When Worthune is the wrong choice
If the job is generating and routing leads
We compute numbers and hand them back. There is no lead capture, no CRM integration, no rate feed, and no campaign layer. An institution buying a conversion program should not assemble one around a calculation API.
Our case
Where we think the difference actually matters
This section is our opinion rather than sourced fact, and it is marked that way on purpose — the table above is what a source URL can settle, and this is what it cannot.
Different question being answered
Theirs is 'how do we turn site visitors into applications.' Ours is 'how do we know this number is right, and can we prove it later.' Both are real; the second is the one that gets asked in a vendor-risk review.
Published price, published method
Enterprise pricing quoted on request is the norm at that end of the market. Ours is on the page, and the free tier runs with no signup, so evaluation does not begin with a demo request.
Callable by anything, including an assistant
REST and MCP, so the arithmetic on the website, in an internal tool, and inside an AI copilot is one versioned model rather than three implementations that quietly diverge.
The receipts come standard
A specification, 250 downloadable test cases, sourced constants with check dates, and a SHA-256 record per run — included rather than assembled for a procurement cycle.
Questions
Common questions
- What does Leadfusion cost?
- Not stated publicly. Their site publishes cost-per-lead benchmarks but no subscription or licensing figures, and routes prospects to a sales conversation or a demo. We checked the site on the date shown in the sources below.
- Are these two products even substitutes?
- Only partly, and it is worth being clear about that. They overlap on 'a calculator on a bank website.' They diverge on everything either side of it — lead routing and campaign measurement on one side, published specifications and audit records on the other. Many institutions could reasonably want both.
- We are a large bank. Is Worthune enterprise-ready?
- Be skeptical, and check. We are a small, young company with no published customer list, and that is a genuine risk factor for an enterprise procurement process. What we can hand you is unusually concrete: the specification for every model, the test cases, the constants with their sources, and an evidence pack per model. Judge us on those rather than on a claim of readiness.
- Can we use both?
- Nothing prevents it. They are not competing for the same slot in an architecture — one is an acquisition layer, the other is a computation layer.
