Keiron develops the HF2 LiFT Printer, a digital, non-contact platform that replaces traditional stencil printing, jet printing and SPI inspection in electronics assembly. The company reports first-pass yield improvements from an industry-typical ~60% to above 95%, a twofold reduction in production lead time, doubled production uptime, and programming that is ten times faster. Those performance gains target high-mix, low-to-medium-volume electronics production, with benefits cited for throughput, working capital and EBITDA. Keiron is a TNO spin-off and has attracted a mix of public and private investors in its recent Series A. The company plans to use the Series A proceeds to scale production and expand its market presence.

Nearfield Instruments designs next-generation scanning probe microscopy systems and the proprietary QUADRA platform to deliver in-line 3D nanometer-scale metrology and non-destructive, high-throughput atomic force microscopy (AFM) with full 3D imaging capabilities. Its systems target critical measurements including sidewall metrology for high-aspect-ratio trenches, GAA recesses, vias, multi-layer stacks, High-NA EUV, CFET architectures, and hybrid-bonded 3D integration. The company emphasizes automation, fast measurement cycles, and compatibility with fab standards for integration into high-volume manufacturing environments. Nearfield works closely with leading semiconductor manufacturers and research partners and operates R&D and support activities across multiple Asia-Pacific and Western markets. The company employs about 450 people and was founded in 2016 as a spin-off from TNO, headquartered in Rotterdam. Following the $380 million Series D at a $1.6 billion valuation, Nearfield plans to expand production capacity, global customer support, Applications Centers of Excellence, and collaborative R&D with chipmakers.

LeydenJar Technologies is a Dutch battery startup focused on manufacturing pure silicon anodes for lithium-ion batteries that can raise energy capacity by 50 % while reducing CO₂ emissions by up to 85 %. The firm targets applications ranging from consumer electronics and AI wearables to electric vehicles and aviation, where higher energy density and faster charging are critical. To industrialize its breakthrough, LeydenJar is completing its first production plant in Eindhoven and aims to begin mass production in 2027. The company recently opened a sales and business development office in Richmond, Virginia, signalling its entry into the U.S. market. Its technology is positioned to overcome the size and weight limitations of conventional graphite anodes, enabling more compact and efficient batteries. Financially, LeydenJar has secured €43 million to date from a mix of equity, customer funding, grants and loans, including a new €7.8 million equity tranche. Dutch pension fund ABP has joined the cap table, and the company was advised by Stifel on its latest raise, underscoring growing institutional confidence in the venture.

Founded in 2020 as a spin-off from TNO’s Biorizon program, Bergen-op-Zoom-based Relement develops and markets bio-aromatics made from agricultural residues. Its flagship molecule, Bio MPA (biobased 3-methylphthalic anhydride), lowers the CO₂ footprint and boosts performance in alkyd paint formulations. The company’s process replaces fossil-derived aromatics with renewable feedstocks, enabling more sustainable coatings, plastics and agro-chemicals. In 2024 Relement partnered with Weylchem-Allessa to scale industrial production and showcased BIOmotion70, a paint containing 70 % sustainable ingredients. Proceeds from its latest financing will fund commercial scale-up and market launch of Bio MPA together with manufacturing partners. The startup has been recognised with the LEVEL UP AWARDS for its contribution to a circular economy. No revenue or user metrics were disclosed in the articles.

Equal1 positions itself as a “quantum semiconductor company,” building quantum processors on conventional CMOS processes so they can be fabricated in existing foundries and deployed without dilution refrigerators or specialized facilities. Its flagship product, Bell-1, is a rack-mounted quantum server designed to slide into standard data-center infrastructure and is already shipping to customers, including an installation planned for the European Space Agency’s Space HPC Center in Italy. The company’s UnityQ processor family follows a quantum-system-on-chip approach that integrates quantum and classical components on a single piece of silicon to cut cost, size, and complexity. Equal1 argues that this architecture will help alleviate power and cost constraints facing classical computing as AI workloads grow. Proceeds from the latest financing will fund broader deployments across high-performance computing centers, increase on-chip qubit counts, scale manufacturing through foundry partners, and expand headcount. Including the new raise, Equal1 has secured more than $85 million in total funding to date.
