What the filings show

Nothing. SEC EDGAR full text search returned zero results for “Fair Square Medicare,” “Fair Square,” and “Medicare Vox” among Form D filings, and zero results among all filing types for “Fair Square Medicare” and “Medicare Vox” as of September 25, 2026. A search on “Petkevich” returned 249 hits, none tied to this company; they belong to an unrelated CIK for a person with a similar surname at a different company. No filing under the founder’s name, the brand names, or any plausible legal-entity variant tested was found.

Reading the record

  1. The company’s own numbers do not agree with each other over time.In August 2022, press materials quoted by Forbes, Fierce Healthcare and the San Diego Business Journal all put total funding at $19 million after the Series A. By September 2024, an industry item describing the same company’s history put lifetime funding at $15 million across two rounds, a figure that matches only the Series A itself. No later release corrects or explains the difference.
  2. A round this size with no Form D on file is unusual but not disqualifying.Companies that raise under other exemptions, such as Section 4(a)(2), file no Form D at all, and a Form D can also be filed under a holding company or predecessor entity name that this search did not test. Absent a filing, the $15 million figure rests entirely on the company’s own announcement, corroborated only by the outlets that reported it at the time, which did not independently verify the number against a document.
  3. The 2022 round came with a named board seat.Define Ventures partner Chirag Shah joined the board as part of the Series A, according to both the company’s release and Forbes’ independent account. No later reporting says whether he remained on the board after the January 2026 acquisition.
  4. The 2026 event is a sale, not a financing.Senior Market Sales, an insurance marketing organization owned by Alliant Insurance Services, announced it had acquired Fair Square Medicare. This is described in the release as an acquisition, not an investment round, and no price was disclosed by either party. It is included here because it is the only capital event on record since the 2022 Series A and because it changes who controls the company.
  5. Headquarters claims move around with the funding claims.The city listed for the company shifts between San Diego, Carlsbad and San Francisco depending on the release, which is worth noting for anyone trying to independently verify a filing by jurisdiction, since a Delaware or California incorporation could show up under any of those addresses.

What to watch

  • Whether a Form D or other SEC filing ever surfaces for this company under any legal name.
  • Whether Senior Market Sales or Alliant discloses acquisition terms in a later filing, since Alliant’s insurance brokerage affiliates sometimes appear in state regulatory records even without an SEC filing.
  • Whether the $15 million versus $19 million funding discrepancy is ever addressed in company materials.
  • Any new capital raised for the Vox platform specifically, as distinct from the original brokerage’s funding history.
