FlexilC develops ultra-low-cost flexible integrated circuits using a proprietary combination of oxide (IGZO) and organic (OTFT) thin-film transistor technologies. The company operates under a fabless model, relying on manufacturing agreements rather than owning production facilities. It is preparing to industrialise and launch its first product families and aims to scale via high-volume applications and future licensing opportunities. FlexilC plans to expand its engineering team and commercial activity with OEM partners as part of its go-to-market efforts. The recent €2 million investment led by Bullnet Capital is intended to accelerate these industrialisation and commercialisation plans.

Bioherent, founded in 2021 as a University of Málaga spin-off, develops miniaturized integrated photonic sensors combined with surface chemistry and advanced nanomaterials to create label-free biosensors for clinical diagnostics. Its core product is the AllerWAVE system, a compact desktop analyzer with disposable cartridges designed for rapid detection of allergies to antibiotics and acute drug reactions used in anesthesia and biological therapies. The company's technology aims to deliver faster, simplified and highly precise analyses without sending samples to external labs, reducing reliance on highly specialized personnel. Bioherent is supported by three university research groups in photonics, chemistry and medicine and has positioned AllerWAVE to address misdiagnoses of antibiotic allergies and associated antimicrobial resistance issues. In July 2025 it raised €2 million in a financing round involving Axon Partners, the CDTI (Innvierte) and Bullnet Capital, and in March it secured an additional €284,000 in a CDTI-led coinvestment to further develop its diagnostic systems.

Founded in 2012, Impetux Optics develops instrumentación fotónica avanzada for the life sciences, with products including Sensocell® optical tweezers and a novel confocal microscopy architecture. Its core innovation uses acousto-optic devices (AODs) to create a fully solid-state, programmable confocal microscope that removes traditional mechanical components. The AOD-based architecture enables high-speed imaging with reduced phototoxicity, greater robustness, and adaptability to varied experimental conditions. With the new financing, the company will industrialize and commercially launch its confocal system, scale production and sales of Sensocell®, and develop an integrated Sensocell®-confocal version as well as a standalone high-performance confocal unit. Impetux will also strengthen its team, industrial capabilities and go-to-market strategy to pursue global opportunities in cell biology, drug discovery and quantitative analysis. The company’s origins lie in research from the Faculty of Physics at the University of Barcelona and it combines that scientific expertise with product development and scientific instrumentation commercialization experience.

Mapsi Photonics develops infrared filters built on macroporous-silicon construction that enable a more controllable and simpler manufacturing process. Their filters deliver higher performance while reducing contamination and environmental emissions. The company originated as a project of the Universitat Politècnica de Catalunya and was founded in 2021. With the new financing it intends to advance its technology, standardize its manufacturing process, and define new product lines to broaden application areas. Cofounders David Cardador and Daniel Segura have stated the goal of scaling the business from startup to scaleup. Bullnet Capital is presented as not only a capital provider but also a strategic partner to help develop the technology and production processes.

Wooptix builds semiconductor metrology systems based on wavefront phase imaging, a technique adapted from adaptive optics research in astronomy. Its flagship product, Phemet®, delivers industry-leading lateral resolution, near real-time process capability and can collect over 16 million data points with sub-nanometer height resolution. Phemet® has been adopted by major semiconductor manufacturers and is on track for full automation and factory-floor deployment for in-line testing in the coming months. The company says its tools rapidly and accurately detect nanoscale defects, addressing growing precision and efficiency demands driven by AI and advanced chip designs. Wooptix has an international presence across Europe, the United States and Asia, with offices in Tenerife, Madrid and San Francisco and headquarters in Spain. The new funding will accelerate product development, expand international reach and scale the team to meet growing industry demand. Wooptix commercializes semiconductor metrology equipment built around its patented Phemet® wavefront phase‑imaging sensor, which measures blank and patterned wafer shape and warpage with higher resolution and in less time than incumbent systems. The company says Phemet® attains nanometer‑scale sensitivity while remaining transportable (about a metric ton), enabling lab and fab deployments. Wooptix plans to automate Phemet® to reduce contamination risk and improve measurement reproducibility, and to integrate the system into existing semiconductor tools from vendors. The business is transitioning from R&D toward product and manufacturing, building infrastructure, procedures, and certifications to support customers as it begins initial tool deliveries. Financially, Wooptix announced a €10 million Series B and was awarded a €2.5 million EIC Accelerator grant that will support product introduction and further technological innovation. The company operates from Tenerife, Madrid, and San Francisco and was founded in 2014. Wooptix is a spin‑off of the University of La Laguna (Tenerife) led by inventor José Manuel Rodríguez Ramos and co‑founders Javier Párraga (CEO) and Javier Elizalde. Its core product, Natural3D, is an image‑processing technology that can produce 3D images and video from standard cameras and has been demonstrated in the astrophysics field. The technology is positioned for applications across smartphones, industrial and professional cameras, medical uses, consumer electronics, augmented reality and high‑precision industrial measurement. Investors have described the company as having a patented product and an experienced engineering team in imaging and optics. Wooptix closed a €3 million financing round that will be used to perfect Natural3D, evaluate new applications and begin commercial development. Erik Jorgensen (Intel Capital) and Javier Ulecia (Bullnet) are set to join the company’s board alongside the co‑founders.
