ewigbyte GmbH

Based in Bavaria, Germany, ewigbyte GmbH specializes in innovative glass-based data storage solutions that ensure data preservation in challenging environments. Their technology utilizes ultrafast laser pulses to create durable nanostructures on glass surfaces. Founded in 2025 and headquartered in Germany, ewigbyte GmbH focuses on developing advanced data storage solutions. The company was established with a vision to address the growing need for reliable long-term data preservation.

The company was founded by Steffen Klewitz (CEO), with Phil Wittwer and Ina Dorothee von Haeften as co‑founders. In October 2025, ewigbyte GmbH raised EUR 1. 6 million in seed funding co-led by new investors Bayern Kapital and Vanagon Ventures, with participation from another new investor AQAL Capital. Other unspecified and individual investors also participated in the round.

Ewigbyte specializes in advanced data storage solutions designed to address the challenges of data preservation in an increasingly volatile environment. The company's flagship technology leverages the creation of nanostructures inscribed onto glass surfaces using ultrafast laser pulses, forming immutable physical structures that can withstand extreme conditions such as heat, humidity, and electromagnetic events. This innovative method ensures that data is preserved over extended timeframes without the need for continuous power, thereby mitigating risks associated with traditional storage media like hard drives and magnetic tape. Ewigbyte targets a diverse range of customers, including governmental institutions, research organizations, and enterprises requiring long-term data retention, particularly in Europe and North America.

By offering a robust alternative to conventional storage systems, Ewigbyte positions itself as a leader in safeguarding critical knowledge and data integrity amidst growing geopolitical and environmental uncertainties. Ewigbyte's revenue model is structured around the sale of its proprietary data storage solutions, with a focus on direct B2B transactions. The company engages with clients through customized partnerships, providing tailored solutions to meet specific data preservation needs. Transactions typically involve the sale of storage systems, which may include integrated services for installation and ongoing support.

Ewigbyte aims to establish long-term relationships with its clients by ensuring reliable performance and support, thereby fostering recurring revenue streams through service agreements and potential upgrades in the future. The company will use this October 2025 funding to further develop its physical glass-based data storage solution and launch it on the market.
