ABSORA secures EUR 1.25 million in pre-seed funding for industrialization of microperforation material

The material startup ABSORA from Bopfingen has closed a pre-seed financing round of 1.25 million euros. The round was led by venture capital investors HEARTFELT_ and Marvelous, supplemented by business angels from the network of better ventures, SB21 and other personalities from the German start-up scene.

The fresh capital will primarily be used to transfer the patented HSA3 microperforation technology into scalable series production and to ramp up the first industrial lighthouse projects. The aim is to enter a European market worth more than 200 billion euros for lightweight construction, sound insulation and filtration.

Industrial noise reduction

In many areas, from power stations and engine rooms to buildings and vehicles, expensive, heavy or environmentally harmful insulation materials dominate the market today. Products such as rock wool or foam work inefficiently, are hardly recyclable and offer only low absorption at low frequencies.

With increasing requirements from legislators and industry, the need for lighter, more sustainable and more effective solutions is growing. ABSORA thus addresses a market with enormous pressure to act and high growth dynamics.

Microperforation with a broad spectrum of action

With HSA3, ABSORA has developed an industrial microperforation material that combines three key functions: it absorbs sound and vibrations across a broad spectrum, reduces flow resistance and is extremely lightweight and high-strength at the same time. It can also be produced more cost-effectively than conventional alternatives.

Our vision is that HSA3 will be used wherever sheet metal is used today - only better: lighter, quieter and more sustainable. We want to become the speed handkerchief of metal construction.

Johannes Kotte, CEO ABSORA

The material is based on ten years of research and development work by Johannes Härle, CTO of the company. At its heart is a patented process that makes microperforations efficient and producible on an industrial scale for the first time.

A team of inventors with tradition and roots in Bopfingen

The technology was not developed in a Silicon Valley laboratory, but in an inventor's workshop in Bopfingen. CTO Härle comes from a family with over 150 successful industrializations. His father, Hans A. Härle, developed the sintered metal soot particle filter for diesel engines, bendable steering columns and sound absorbers for aviation, among other things.

Over the years, Johannes Härle developed HSA3 from initial ideas in the workshop to a marketable material technology innovation.

Investors focus on platform potential for entire industries

Several well-known angel investors are supporting the round, including personalities from goodgrow vc, Knälmann Venture Partners, Robert Levenhagen, Helmut Deschauer, Dominik Stiefermann, Freddy Martin and numerous successful founders from the SB21 environment.

ABSORA combines in-depth technical know-how with bold implementation power. We are not just investing in a material, but in a platform potential for entire industries.

First pilot projects already underway

HSA3 is already being tested in various industrial pilot environments, including gas-fired power plants, HVAC systems and sound insulation applications. Together with FläktGroup, which belongs to Samsung, ABSORA is working on products for ventilation and air conditioning technology In Europe alone, the target markets for ABSORA amount to over 200 billion euros with annual growth rates of more than eight percent.
