Comparison
Worthune vs Black Diamond
Black Diamond, from SS&C, is a wealth platform with portfolio management and reporting, a firm-branded client portal and app where clients can add outside accounts, REST and batch APIs for its clients and partners, and an MCP server. Worthune has no portal of its own and no aggregation or reporting: it is a versioned household record and planning engine your own product owns, with white-label embeds, a public API, a published price, and a free sandbox. Buy Black Diamond for a ready portal on its portfolio data; compare Worthune if you are building the experience.

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 | Black Diamond | |
|---|---|---|
| How it is delivered | REST API, MCP server, and a one-script-tag embed | A web platform, a firm-branded client experience portal and mobile app, and REST and batch APIs |
| Client-facing portal or app | No app of our own; household embeds and a white-label reference build ship under the customer's brand, with attribution removal on Growth | Yes — a firm-branded client portal with a view of the client's wider wealth picture, and a mobile app with branding options |
| Account aggregation | No — Worthune does not aggregate accounts or connect custodial feeds; households are kept current by bulk import of the customer's aggregator or custodian exports, with a dry run | Yes — clients can add outside accounts such as bank accounts, credit cards, 401(k) plans, and annuities in the portal |
| How households are modeled | A versioned household record the customer's product owns through the API: members, accounts, incomes, and obligations, re-projected on change, with signed webhooks when a stored plan's numbers drift and a decision history per household | Client relationships (households), contacts, portfolios, and client portal users are an API data category |
| Programmatic API | Yes — REST and MCP, no key required for the three sample models | Yes — real-time REST APIs to create, update, delete, and extract data, a batch module for bulk extracts, and a testing environment for the firm and trusted partners |
| MCP server for AI assistants | Yes — a remote MCP server; three models keyless, household and Lodestar tools with a key, including a free sandbox key | Yes — an MCP server connects AI tools to Black Diamond through a governed connection |
| Pricing model | Subscription; three models free with attribution, no per-run metering | Not stated publicly; the site routes prospects to request a demo |
| Entry price | Free for three models; $495/month for the full catalog | Not stated publicly |
| Track record, as published | A new company with a small team and no published customer list | Reports 1M active users, $4.6T+ in AUM, and 3,300+ firms; its API brief cites 1,400+ firms using the API |
Where Black Diamond is stronger
A finished, branded portal on portfolio data
Black Diamond gives a firm a branded client portal and mobile app on top of its portfolio data, lets clients add outside accounts themselves, and runs an API used by a large number of firms (see the track-record row). A firm that wants clients seeing their whole picture under its brand next quarter, without building anything, gets that out of the box. Worthune would make you build the interface.
When Worthune is the wrong choice
If you want a client portal without building one
Worthune ships embeds and a white-label reference build, not a hosted portal with performance reporting and outside-account linking. A firm that wants a portal working this quarter should buy one, and Black Diamond is an established choice.
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.
Planning and decisions on the household
Projections, coordinated strategies, and a decision history on each household record, with Lodestar proposing moves for an advisor to approve. The portal shows the plan, not only the portfolio.
Drift, pushed to you
Signed webhooks fire when a stored household's projected numbers move after new data or a rule change, so your product can act on it.
Open to evaluate
Public API reference, OpenAPI document, SDKs, and MCP tools, with a free sandbox key by email and a published price.
Numbers you can trace
Every model has a versioned specification and downloadable test cases, and every run returns a record tying the number to the version that produced it.
Questions
Common questions
- What does Black Diamond cost?
- Not stated publicly. Its site routes prospects to request a demo, as of the date in the sources below.
- Does Black Diamond have an API?
- Yes. Its API product brief describes real-time REST APIs to create, update, delete, and extract data, a batch module for bulk extracts, a developer portal, and a testing environment for the firm and trusted partners. Households appear as client relationships in its data categories.
- Does Worthune have a client portal?
- Not a hosted one. Worthune provides household embeds and a white-label reference build that you deploy on your own domains under your brand; the full white-label branding is on the Growth plan.
- Does Worthune aggregate outside accounts?
- No. Households are kept current by bulk import of your aggregator or custodian exports, with a dry run that returns every error before anything is written.
