What The Onyx Group does
The Onyx Group is a private, for-profit professional services firm headquartered in Greer, South Carolina, operating with a headcount of 51–100 employees. According to available firmographic data, the company offers a bundled suite of back-office services: revenue cycle management (RCM), accounting, human resources, payroll processing, and practice management consulting. The mix — particularly RCM and practice management consulting — points to healthcare provider practices and small-to-mid-sized professional services firms as the likely end customer, using Onyx as an outsourced alternative to building internal finance, billing, and HR infrastructure. The organization's South Carolina base and use of a `.org` web domain (onyxsc.org) suggest a regionally anchored, relationship-driven business rather than a national platform play.
The firm's revenue mechanics, pricing structure, and go-to-market channels are not disclosed in the available source data. There is no public pricing, no named product suite, and no proprietary technology platform described; the offering reads as labor-based professional services rather than software-enabled delivery. Distribution and marketing channels are likewise unstated, consistent with a referral- and relationship-led sales motion typical of regional services firms. The company's own website was inaccessible at the time of data capture, returning only a loader/verification page with no substantive content, which represents a material information gap: investors and acquirers would require direct management outreach, customer references, and financial diligence to confirm contract structures, customer base composition, technology stack, and revenue quality before underwriting or valuation work.
**Key data gaps:** No disclosed revenue, no funding history, no leadership team details, no customer logos, no M&A or partnership history, no AI/technology stack, and an inaccessible primary web presence. These gaps materially limit any investment thesis and should be resolved through primary-source diligence prior to any capital deployment decision.
