About Planet 9
We are Clemens Foisner and Jürgen Kraupa, and for over 30 years we’ve been building ventures together.
Along the way, we’ve launched and scaled numerous projects and companies, guiding many to successful exits. But every success is just the beginning of the next adventure. There is always more to explore, more to create, and more to bring to life.
Planet 9 is the expression of that mindset — our commitment to moving forward and turning ideas into reality.
Under this brand, we bring together our international projects and entities in information security, alongside our newest passion: developing real estate projects in and around our hometown of Wiener Neustadt.
