Third party filings
None. No Form D by another filer, including single company investment vehicles, names Onederful.
Other federal records

What that leaves

Reading the filings

  1. The absence of a Form D is consistent with the size.Form D is filed for offerings sold under Regulation D. A Y Combinator investment is normally a convertible instrument, and companies that raise under Section 4(a)(2) file nothing. At $120,000 total raised, there was no priced round to notice. The gap is evidence of a small raise, not of a hidden one.
  2. This is one of the cheapest exits in the cluster.$120,000 raised against 240 stated payer connections works out to $500 of disclosed outside capital per carrier connection. Y Combinator lists the team at 2 people at the time of the acquisition. Whatever the purchase price was, the dilution before it was minimal by construction.
  3. The money was on the buy side, not the sell side.Vyne was acquired by The Jordan Company in 2019, then bought Renaissance Electronic Services in February 2020 and, per its own December 2021 release, Tesia Clearinghouse and OperaDDS as well. Onederful was the fourth named bolt-on in under two years. A sponsor backed roll-up, not a strategic bidding war, set the price.
  4. Nobody disclosed the price, and no filing forces them to.Inside INdiana Business reported flatly that terms were not disclosed. Both sides were private, the buyer files no periodic reports, and no state or federal record captures the consideration. Any number circulating for this deal is an estimate.
  5. The asset outlived the company.Five years after the sale, developers.onederful.co still serves live API documentation, now titled the Vyne API Documentation Portal, with production endpoints on the onederful.co domain. Vyne markets Onederful API as one of three eligibility APIs alongside ClearCoverage API and a Standard API. That continuity is the clearest available proxy for the asset having been worth the price.

Standards exposure The product wraps X12 270, 271, 837 and 835 transactions. Those formats are published and open, so the moat is normalization and payer relationships, not protocol access. Public record

What to watch

  • Whether Vyne retires the Onederful brand in favor of ClearCoverage API, which it now positions as the newer product.
  • Any disclosure of the purchase price, which would most likely surface in a future sale or recapitalization of Vyne by The Jordan Company.
  • Movement in the stated payer count, which has fallen from 240 to 200+ in public materials.
  • Pricing pressure from Stedi and DentalXChange in the dental eligibility API market.
