What the filings show

No filing shows anything, because none exists. A search of SEC EDGAR’s company database for Form D filings under the name “health harbor” returns zero results, and a full text search across all SEC filings for the phrase “Health Harbor” also returns zero results, checked September 25, 2026. No CIK number has been assigned to a company by that name in EDGAR. The only funding figure available anywhere is the $500,000 pre-seed round that VCBacked lists as last reported in September 2023, attributed to Y Combinator as sole investor. VCBacked does not cite a press release, a filing, or any other primary source for that number.

Reading the filings

  1. There is no Form D to read.Companies that raise only from Y Combinator under YC’s standard deal, or that raise under Section 4(a)(2) rather than Regulation D, can go without filing a Form D at all, so the absence of a filing does not by itself mean no money moved. It does mean the $500,000 figure cannot be checked against a primary document.
  2. The reported amount matches YC’s typical check size.Y Combinator’s standard deal for its batches has long combined a fixed cash investment with an uncapped note, landing most batch companies at a total in the low hundreds of thousands to half a million dollars. A $500,000 pre-seed figure for a company that went through YC’s Summer 2023 batch is consistent with that pattern, though Health Harbor has not confirmed the number itself.
  3. Revenue is modeled, not disclosed.GetLatka’s $440,000 estimate for 2025 annual revenue is built from GetLatka’s own estimation methodology rather than a number the company has published. Health Harbor’s own website does not state a revenue figure.
  4. Employee counts do not agree, which limits what can be inferred about growth.LinkedIn shows 2 to 10 employees, GetLatka recorded 4 as of June 2024, and Tracxn recorded 16 as of July 2026. If the Tracxn figure is accurate it would suggest a hiring wave sometime after mid-2024, but no announcement, job posting count, or other record confirms that.
  5. No later round has surfaced.Three years after the Summer 2023 batch and the pre-seed figure, no seed, Series A, or other named round appears in any source checked for this profile.

What to watch

  • Whether a Form D appears for the pre-seed round or any later round.
  • A company-confirmed funding total, since the only figure now available comes from a single third party tracker.
  • Resolution of the employee count gap between LinkedIn, GetLatka and Tracxn.
  • A disclosed revenue figure from the company itself.
