With Kristian Kläger’s investment, Bitsurance gains not only capital but also a strategically strong partner with deep expertise in Bitcoin technology, an extensive network, and significant reach. The investment underscores Bitsurance’s ambition to professionalize and scale Bitcoin insurance solutions sustainably across Europe. Through various business development activities, the company aims to expand its product portfolio, significantly increase coverage amounts, and design solutions tailored for corporate clients. Joint trade fair appearances by terahash and Bitsurance complete the collaboration package.
Kristian Kläger drives strategic partnerships and synergies
