Qubyx

What Qubyx does

Qubyx is a privately held software company founded in 2002 by Dr. Marc Leppla and headquartered through dual legal entities (QUBYX Limited in Hong Kong and QUBYX Holding LLC in the United States). The company specializes in digital color technology, with its core product being PerfectLum 4, a DICOM Part 14 GSDF-compliant calibration and quality assurance application for medical displays. PerfectLum supports an unusually broad set of medical imaging standards (AAPM TG18, AAPM TG270, DIN 6868-157, DIN 6868-57, ACR, NY/NYC PDM, MQSA, IEC 62563-1) and is sold on a per-workstation perpetual basis covering up to six displays, with a 15-day free trial and a freemium entry product (QUBYX OS Tools). Complementing the software is the proprietary SmartSensor S1 colorimeter and the PerfectLum Remote QA Server ($2,000), available as a hosted or locally installed service.

The company's primary customer segment is healthcare radiology, with named users including Columbus Radiology, MDSynergy, Zwanger-Pesiri, Radiology Associates of Ridgewood / Valley Hospital, and Riverside Radiology. Secondary segments include display and projector manufacturers served through an OEM embedded licensing channel, plus professional color industries (photography, prepress, graphic design, print) and emerging industrial-imaging use cases. Distribution combines a direct e-commerce storefront, a reseller/VAR program with volume-based discounts, and OEM licensing offered as license-only or full white-label packages including source code.

The business model is predominantly perpetual software licensing with modest recurring components (hosted QA server, maintenance plans) and a smaller hardware and OEM licensing tail. The company has been founder-led for over two decades without external institutional investment, and has signaled expansion through the open-source QubyxViewer (2025), a reseller program, OEM embedded licensing, multilingual website rollout, and entry into industrial and automotive verticals.
