What Exaddon does

Exaddon AG is a Swiss privately-held company, founded in 2019 as a spin-off from Cytosurge AG and headquartered in Glattbrugg, Switzerland, that develops and commercializes high-precision metal additive micromanufacturing solutions built on proprietary local-electrodeposition (electrochemical) micro-3D printing. Its core technology uses hollow AFM cantilevers with a 300 nm aperture to deposit pure metals voxel-by-voxel at room temperature, producing complex 3D metal structures from 1 µm to 1000 µm with sub-micrometer resolution and 99.5%+ density, requiring no post-processing. Exaddon operates two product segments: a semiconductor-industry business selling custom MicroLED Probe Cards, WAT/Parametric Probe Cards, and Application-Specific Probe Cards for wafer-level testing at pitches below 20 µm (versus a ~40 µm industry limit) and with ultra-low leakage below 1 fA/V, and an academic/industrial R&D business selling the CERES Printing System to research institutions for microscale metal 3D printing in neuroscience, photonics, 5G/6G, and materials science.

The company monetizes through direct enterprise field sales of custom-developed probe cards developed in co-development cycles, complemented by sales of CERES systems via exclusive regional distributors (Quantum Designs in the USA, AXT in ANZ, Germantech in China) and via technical content marketing including white papers, SWTest/Display Week conference presence, and peer-reviewed publications. Named enterprise relationships include Synergie Cad Instruments (co-development partner since 2022), Advantest and MPI Corporation (test-equipment integration), Axon' Cable (medical interconnect plugs), and an installed academic base spanning Georgia Tech, KIT, Cardiff, Purdue, Max-Planck, Oregon, Pisa, CUST, FBH Berlin, and Goethe-Universität Frankfurt. Revenue, funding, and headcount are not publicly disclosed; the company appears to operate with a small specialized engineering team of electrochemists, process engineers, and product managers.

Exaddon's competitive position rests on a single differentiated process: it claims to be the only commercial vendor producing complex pure-metal 3D objects at sub-micrometer resolution at room temperature without post-processing, validated through Best Paper Awards (Micromachines 2022) and SWTest conference recognition (Best Data Presentation 2023, Most Inspirational Presentation 2025). Primary product-market risks are dependency on the emerging MicroLED adoption curve and the broader semiconductor advanced-packaging transition, alongside modest scale and undisclosed financials typical of an early-stage industrial spin-out.

Revenue model

1. MicroLED Probe Cards: Sale of custom micro-3D printed probe cards specifically designed for MicroLED wafer-level electroluminescence (EL) testing. Probe cards are developed in close collaboration with customers from feasibility assessment through prototype evaluation and production. Revenue is generated through product sales and likely involves multi-year customer engagement cycles.
2. WAT/Parametric Probe Cards: Sale of probe cards for wafer acceptance testing (WAT) and parametric testing. These deliver controlled contact behavior for deep trench structures and sensitive parametric measurements, enabling reliable data collection across wafers and process iterations.
3. Application-Specific / Custom Probe Cards: Custom probe card solutions developed collaboratively with customers for unique testing challenges including microbump contacts, four-point contacts, low-invasive pad scrub tests, and fine-pitch applications.
4. CERES Printing System: Sale of the CERES micro-3D printing system to academic and industrial R&D customers. The standalone system is sold to research institutions globally for microscale metal additive manufacturing applications including neuroscience, photonics, 5G/6G components, and materials science research.
5. White Papers and Technical Documents: Exaddon publishes downloadable white papers on material properties, probing techniques, microscale AM landscape analysis, surface topography mapping, and gold printing. These serve as marketing/educational resources that support hardware sales.

Core offering

Exaddon manufactures micro-3D printed metal probe cards for advanced semiconductor wafer-level testing (MicroLED EL testing, WAT/parametric, and custom applications), and sells the CERES standalone micro-3D metal printing system to academic and industrial R&D customers. Its proprietary electrochemical deposition process builds pure metal 3D structures at sub-micron resolution at room temperature without post-processing.

Product overview

Exaddon's product portfolio centers on two distinct segments: semiconductor industry products and academic/industrial R&D solutions. The semiconductor segment comprises three probe card product lines—MicroLED Probe Cards, WAT/Parametric Probe Cards, and Application-Specific Probe Cards—all powered by proprietary micro-3D printed probes that enable precision wafer testing where conventional probes reach their limits. The R&D segment features the CERES Printing System, a standalone microscale metal 3D printer that brings Exaddon's proprietary electrochemical deposition technology to research environments for creating sub-micron metal structures. The product line is unified by Exaddon's core micro-3D printing technology platform, with probe cards applying this technology to semiconductor testing applications and CERES making it available as a research tool.
