Summary

The Empa spin-off Swiss Cluster has won the Swiss Economic Award 2026 in the "Production/Trade" category. Founded in 2020 and headquartered in Spiez, the company develops equipment for vacuum-based coating processes that protect complex components and produce functional thin films with high mechanical and thermal resistance. Swiss Cluster employs 15 staff members and supplies research institutions and customers from the watch, optics, and electronics industries worldwide. The company was founded by Carlos Guerra and Kevin Lücke and is one of the few high-tech start-ups that grew profitably from the outset.

The award underscores a strategic advantage of Switzerland: the ability to convert academic research directly into market-ready products. Swiss Cluster represents a new type of industrial company – compact, modular, and accessible – that democratizes established processes and thereby lowers previous barriers to market entry. For decision-makers in research and industry, this signals that specialized coating technologies will in future be available to small and medium-sized enterprises, not just semiconductor giants.

Detailed Summary

Swiss Cluster combines two established thin-film production processes in a single vacuum chamber: Physical Vapor Deposition (PVD) and Atomic Layer Deposition (ALD). While PVD produces hard layers, ALD enables precise, homogeneous, and corrosion-resistant layers at the atomic level. The combination of both techniques was long a laboratory challenge – originally, substrates had to be manually transported between separate chambers, leading to surface oxidation. Swiss Cluster's first machine solved this problem through integration of both processes: nanostructured layers that required a week in the laboratory are now produced within a few hours.

The business model deliberately differs from the semiconductor industry, where combined PVD-ALD systems are already established. Swiss Cluster focuses on broader markets – from watch components to optical systems, medical implants, and batteries. The company also offers a separate batch-ALD device that enables faster and parallel coating. In addition to equipment sales, Swiss Cluster operates its own coating laboratory in Spiez, where customers can test processes before investing. This service simultaneously serves as a feedback channel for product improvements.

The company's growth followed an unconventional path: while typical high-tech start-ups seek external investment early on, Swiss Cluster financed itself organically through equipment and service sales. The first external investment came only in 2025 – five years after founding. This strategy required operational excellence from the outset and is recognized by the jury as a combination of "scientific excellence, industrial understanding, and entrepreneurial implementation."

Key Messages

  • Swiss Cluster combines two complementary thin-film technologies (PVD and ALD) in an integrated vacuum chamber, thereby reducing process times by over 90 percent.
  • The company democratizes high-precision coating technologies through compact, installation-friendly equipment, making them accessible to industries outside the semiconductor sector.
  • Swiss Cluster grew profitably and organically without external investment until 2025 and today supplies customers in Switzerland, the USA, and the United Kingdom, with plans for expansion to France, Brazil, Italy, and China.

Critical Questions

  1. Evidence/Data Quality: What quantitative metrics substantiate the claimed efficiency gains (e.g., reduction of process time from one week to a few hours)? Have these been independently verified or do they come exclusively from Swiss Cluster itself?

  2. Conflicts of Interest: To what extent does Empa as the founding institution benefit from the commercialization of the spin-off through licensing fees or equity stakes, and could this influence research independence?

  3. Causality/Alternatives: Is the organic growth strategy a sign of market maturity and customer demand, or evidence that external investors deemed the business model too niche? What alternative scenarios for company growth were evaluated?

  4. Feasibility/Risks: How scalable is the batch-ALD process to industrial volumes? What technical or economic hurdles could jeopardize the announced international expansions?

  5. Market Position: What established competitors exist in the combined PVD-ALD systems market, and how does Swiss Cluster differentiate itself beyond price and compactness competencies?

  6. Customer Validation: How many commercial devices have been sold to date, and what customer satisfaction metrics or repeat rates are available?
