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.
