The market potential

With a market potential of 13 billion US dollars and annual growth rates of 7 % in Europe, the private aviation business is an extremely attractive market. Most travel verticals are home to operators and marketplaces that simply enable digital bookings to be made, letting them position themselves as the leading companies in the verticals in question. However, this is not yet the case in the field of private jet bookings, although the shopping basket values are much higher than in the other verticals. By digitizing and simplifying the booking process for private aviation, JetApp was able to establish itself in the private aviation market within a very short time and thus successfully occupy an extremely attractive niche.

Moonfare is a technology platform via which private persons and their advisors gain access to the TOP private equity funds and can invest in them online, in a completely straightforward manner.

Due to the more than twice as high average returns compared to the stock market (Global PE Index Top Quartile vs. S & P 500) over the past 10, 15 and also 20 years, there is a huge, largely unsatisfied demand from private investors to invest in the TOP PE funds.

In addition, the young company has already raised more than 25 million euros of investment capital for its own growth. The KOEHLER GROUP has been a founding investor in Moonfare since 2017.
