About Us
Insight KB
This is Stephan Ketterer and Daniel Braitsch.
As a trained industrial mechanic specializing in precision mechanics, Stephan Ketterer recognized an everyday problem in machining on CNC machine tools. The view into the machine room is permanently impaired by splashing emulsion during the machining process.
When he told Daniel Braitsch about the problem, the two decided to find a solution together. The aim was to place a product on the market that would offer a quick and easy improvement for the CNC industry.
Thanks to the excellent network and entrepreneurial knowledge of Daniel Braitsch and the technical expertise of Stephan Ketterer, they have succeeded in developing a cost-effective and simple solution and bringing it to market.

OUR HISTORY
2020
2020 – Founding and development of the first product
The idea for and development of the clear protective screen began in 2020. The resulting company, Insight KB, was founded in 2021 by Stephan Ketterer and Daniel Braitsch in Stegen, near Freiburg. The catalyst was an everyday problem in CNC manufacturing: dirty viewing windows made it difficult to monitor the process while working with CNC machines. During the COVID-19 pandemic, Stephan Ketterer developed the idea of a replaceable protective film for CNC viewing windows. Together with Daniel Braitsch, this evolved into a market-ready product following extensive testing.
Market Launch and Initial Growth Phase
By 2023, the protective film had become increasingly established in the CNC industry. Insight KB secured its first distributors and industrial customers and, from the very beginning, relied on digital marketing, social media, and word-of-mouth recommendations rather than a traditional sales force. At the same time, the company entered its first international export markets, laying the foundation for further growth.
2023
2023 – International breakthrough
In 2023, Insight KB achieved its international breakthrough. The company secured a major client—a world-leading mechanical engineering group—which used the protective film on its demonstration machines. The presentation at the CNC Turning and Milling World Championships (part of WorldSkills) further increased the company’s international visibility. Distributors from Canada, the U.S., and Scandinavia added the products to their lineups, while the first machine manufacturers began integrating the protective film as a standard accessory.
Company expansion
Through 2025, Insight KB consistently continued on its growth trajectory. The international dealer network was further expanded, and the products were now being shipped to more than 50 countries. Approximately 80 percent of revenue was generated abroad. With a monthly production of 3,000 items and seven-figure annual revenue, the company established itself as a successful international niche provider.
2025
2025 – Expansion of the product portfolio
In 2025, Insight KB evolved from a manufacturer of a single innovation into a specialist in accessories for CNC machines. In addition to the protective film, the portfolio was expanded to include, among other items, protective screens for LED machine lights and height-adjustable dispensing valves with magnetic bases. Throughout this process, the company remained true to its strategy of solving real-world challenges with simple and effective products. Growth continued to be driven primarily by word-of-mouth recommendations, social media, and digital visibility—all without traditional sales efforts.
