Reading the record

  1. No Form D is on file.A $9.1M institutional round with named lead investors would typically generate a Form D within 15 days of the first sale under Regulation D. None has been found under Kopra Bio’s name. Companies raising through simple agreements for future equity, as Y Combinator companies commonly do for their initial round, or under other exemptions, do not always file one, so the absence is a gap in the record rather than proof the round did not close.
  2. One person holds every officer title.The 2024 state filing lists Andrew Bartynski as CEO, CFO and secretary all at once, a common structure for a company with a handful of people. Scientific cofounder Alexander Haddad and the UCSF faculty cofounders are not listed as corporate officers in this filing.
  3. Aggregators disagree because they are looking at different moments.Tracxn’s snapshot, taken in January 2025 before the seed round closed, shows total funding of $500K. PitchBook’s more current profile puts total funding at $9.7M and lists 20 investors, only five of them named. The difference is almost entirely the $9.1M seed that closed in June 2026, after Tracxn’s snapshot was taken.
  4. Non-dilutive and in-kind support sit outside the cash totals.The $100,000 QB3 award and the Charles River Incubator Program’s services are not part of either the $500K or the $9.1M figures reported elsewhere. Neither is the proposed King Faisal Specialist Hospital arrangement, which is structured as in-kind contributions for equity rather than a cash check, and which remains a memorandum of understanding rather than a signed, funded agreement.
  5. The company’s own website says little.As archived in July 2026, kopra.bio consists of a name, a one-line tagline, a contact email and a row of investor or partner logos with no funding figures, named investors or team page. The funding numbers in this profile come entirely from press coverage and aggregators, not from the company’s own site.

What to watch

  • A Form D for the $9.1M seed round, or an amended filing that clarifies amount sold versus offered.
  • Whether the King Faisal MOU converts into a funded, signed trial agreement.
  • Named investors beyond the five reported by aggregators.
  • Whether the China Phase I trial opens and what it costs to run.
