€2.9 Million Investment from the Companisto Business Angel Network and Product Sell-Out Following Strong Media Coverage for PerioTrap
Fraunhofer spin-off responds to continued investor demand with an additional investment window.
The biotech startup PerioTrap has successfully closed the first tranche of its Pre-Series A financing round via the digital business angel network Companisto. A total of €2.9 million was invested in the company. bmp Ventures participated in the round through the IBG funds with a €1 million co-investment. The round will remain open for additional tranches until May 2026.
PerioTrap is a spin-off of the Fraunhofer-Gesellschaft and is developing a novel therapeutic approach to treat periodontal disease. Its selective active ingredient specifically targets key plaque-forming bacteria while preserving the healthy oral microbiome.
Dominik Malter, Investment Manager and Program Manager at Fraunhofer Venture, commented:
“Seven years ago, we set out to take the long journey from a Fraunhofer laboratory to a market-ready end-consumer product through a spin-off. Thanks to an outstanding founding team and strong support from our investor base, we have now reached a major milestone and brought a true innovation to market.”
Following the official close of the Companisto financing round in early January 2026, PerioTrap continued to receive numerous investment inquiries driven by increased public visibility. To accommodate the strong demand, the company opened a short additional investment window for the Companisto Business Angel Network.
One driver of this demand was significant media coverage. A press release issued by the Fraunhofer-Gesellschaft about PerioTrap’s technology generated widespread national and international attention. As a result, the company’s microbiome-friendly toothpaste sold out within 12 hours.
Nicky Hughes, Investment Director at Companisto, said:
“The financing round demonstrated that PerioTrap has generated broad and sustained interest among our business angels. The one-time additional investment opportunity for the Companisto Business Angel Network enabled us to meet this strong demand and further strengthen the round. Beyond the investment itself, our network will continue to support the company with expertise and connections as it scales. This was already evident during the soft launch, where members of the Companisto network actively supported the market introduction.”
Pierre Tangermann, CEO of PerioTrap, added:
“The strong response to the financing round highlights investor confidence in both our technological approach and our equity story. We deliberately chose a combination of experienced venture capital investors and an active business angel network in order to effectively combine market access, scaling capabilities, and entrepreneurial sparring.”
Andreas van Bon, Partner at bmp Ventures, commented:
“We are pleased that PerioTrap has successfully raised the capital required for its next development phase and broader market entry, while also strengthening the Halle (Saale) location with the support of the IBG funds.”
With the capital raised from the business angel network, PerioTrap plans to execute its next growth steps, including expanding its sales activities internationally and advancing its product pipeline.
