How does participation in Attensys work?

Your participation in Attensys is structured as an equity investment. You become a shareholder in Attensys - similar to investing on the stock market, but in the pre-IPO phase. No subordinated loans, no reward-based crowdfunding campaigns, no pre-orders. In the event of success, you participate proportionally in the exit (company sale or IPO) or via dividend distributions. Example: Companisten who invested in BigRep participated in its listing on the Frankfurt Stock Exchange on July 31, 2024 (ticker B1GR). The minimum investment in Attensys is €10,000 in the Business Angel Club (for direct investments in the form of shares or GmbH equity interests) or €250 for private investors via a pooling vehicle. Each investment offering includes a legally required Securities Information Sheet (WIB), Key Information Document (BIB), or consumer information with mandatory risk disclosures.

Examples from the Companisto portfolio: BigRep - listing on the Frankfurt Stock Exchange on July 31, 2024 (ticker B1GR). HERO - €40 million Series B in 2024 with Eight Roads and Federated Hermes. DiaMonTech - €8 million co-investment with Samsung Next in 2025 (largest EU equity crowdfunding round 2025). KoRo 6x return for Companisten upon sale in 2022.
