Du suchst nach Kursen für dich oder deine Kinder, weisst aber nicht genau, wo du anfangen sollst? Die Informationen erscheinen versteckt und du erfährst nur zufällig von Freunden, wo Kurse stattfinden? Wer Kinder hat, kennt das Problem. Bei der Buchung wächst dann der Frust, da man am besten nur montags und mittwochs zwischen 9 und 12 Uhr anrufen kann, nur leider ist doch Donnerstag. Aus Anbietersicht verständlich, um der Telefonflut zu entfliehen. Nun gibt es eine Lösung für diese Herausforderungen: Kursfreunde - die neue, zentrale online Plattform vorerst in München, auf der Familien Kurse für alle Familienmitglieder einfach online buchen können: für Schwangere, frisch gebackene Mamas, Babys, Kinder, Jugendliche oder Eltern generell. Die Vielfalt an Kursen erstreckt sich über Sport, Musik, Kunst, Forschung & Digitales und viele weitere Kurse. Es gibt Kurse, die über ein paar Wochen gehen, Einzeltermine, Workshops & Seminare und vieles mehr. Du bist in München, neugierig und wolltest schon lange mal wieder etwas Neues machen? Oder du weisst genau, was du möchtest und würdest den Kurs gerne einfach und bequem online buchen? Vielleicht bist du auch ein Kursanbieter, der gerne seine Kurse auf Kursfreunde vermarkten würde? Schau gerne vorbei - wir freuen uns auf dich!

Radenbrocks objective is to democratize successful investment strategies from the portfolio of hedge funds and high-frequency traders, making them accessible to a broader public. While this type of speculative investment has so far only been accessible to investors who have a minimum investment of EUR 500,000 or more, Radenbrock offers a comparable and above-average performance from an investment of EUR 25,000. Although there are already some Robo Advisor on the market, almost all their trading strategies are based on ETFs, a passive investment and the occasional rebalancing of the portfolio. The yields of this passive asset management are heavily dependent on the development of the overall market. Radenbrocks strategies, on the other hand, make use of market inefficiency in comparatively short periods of time and are thus independent of the overall market or possible shortcomings.
