What VSTech does

VSTech is a French deep-tech company that designs and develops organic photodiode (OPD) sensor technology and optical systems for machine vision, biometric authentication, vital sign monitoring, and CMOS imaging applications. The company was founded in 2024 by a team with more than ten years of experience in optical sensors and printed electronics, and operates from three French locations: its headquarters in Bègles, an R&D site co-located with ELORPrintTec in Pessac, and an additional office in Grenoble. The company's stated ambition is to become a leader in application-specific optical sensors and to establish the world's first OPD mass production capability. VSTech targets the healthcare/wearables, security/biometrics, cryptocurrency hardware, and CMOS camera manufacturing verticals. Distribution is exclusively B2B via direct OEM engagement and strategic partnerships (notably G-Knot for crypto/enterprise security and mofiria for vein recognition), with no retail or self-serve channels.

VSTech's product platform is built on a proprietary OPD architecture: organic semiconductor materials are deposited via slot-die coating on rigid glass or flexible plastic substrates at room temperature, and the polymer ink can be tuned to span visible through NIR/SWIR wavelengths. This produces sub-millimetre, flexible, low-power monolithic sensor stacks that can be laminated onto TFT or CMOS backplanes. The company holds 82 patents across 34 families and protects what it describes as unique ink formulation know-how. Commercial product variants include ThinRing (a smart ring for vital sign monitoring, shown at CES 2026 with ENGO Light AR glasses integration), a Miniature Vein Reader for biometric authentication in hardware wallets and access control, and a CMOS SWIR Camera targeting NIR/SWIR detection on standard CMOS wafers at 100M+ unit scale.

The business model combines hardware sales (OPD sensors sold to OEMs for integration into their devices) with technology licensing to partners. Pricing is quote-based for enterprise customers, with no public pricing disclosed. GTM is OEM-embedded and partnership-driven, complemented by event-led demand generation at venues such as CES and Milipol. No revenue, funding rounds, or paying customer logos have been disclosed, and the company's first commercial production milestone (with G-Knot) is targeted for 2027.
