Harness Wealth
Harness — the company that launched as Harness Wealth, and today a wholly owned business of Multiplier, Inc. — is a New York City firm that runs an advisory platform for tax and wealth practices. It operates three connected surfaces: a marketplace that matches individuals with complex financial situations (equity compensation, liquidity events, business owners, real estate, high net worth) to vetted tax advisors; a client portal and workflow platform that tax firms run their engagements, documents, questionnaires and e-file on; and Harness Wealth Advisers, LLC, an SEC-registered investment adviser that recommends third-party advisers. Harness publishes no public developer program — there is no developer portal, API reference, OpenAPI/GraphQL/AsyncAPI specification, SDK, CLI or webhook documentation on any Harness host, and the product is delivered entirely as an end-user web application at app.harness.co.
Harness Wealth is profiled on the APIs.io network. Tagged areas include Company, Financial Services, Tax, Wealth Management, and Accounting.
Harness Wealth’s developer surface includes engineering blog, support, and 13 more developer resources.
