description: '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.'

  note: harnesswealth.com 301s to https://www.harness.co/ (probed 2026-08-22, HTTP 200 at the redirect target). The harvest
    backlog recorded the secondary-market venue homepage (https://www.nasdaqprivatemarket.com/) as this company's Website;
    that pointer was wrong and has been replaced with the company's own site, with the venue recorded as SecondaryMarket against
    the EquityZen listing that names Harness Wealth directly.

  detail: Harness ships its tax-advisory platform only as an end-user web application at app.harness.co — api.harness.co,
    docs.harness.co and developer.harness.co do not resolve in DNS, the marketing site returns a hard 404 for /llms.txt, /openapi.json
    and every /.well-known/ path, and the only host that answers a spec probe is the client SPA, which returns the same 18,352-byte
    HTML shell for every unmatched path.
