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.
