BTG Global Advisory specialises in the stabilisation and turnaround of underperforming real estate properties. It is our mission to mitigate the effects of a detrimental event that disrupts income generation and threatens property valuation.
Our experienced real estate advisors act quickly when stabilising a troubled property. We identify the most critical issues and develop a list of priorities that must be addressed immediately. These actions halt the downward performance trend and protect the underlying value of the property.
Once we have stabilised a property we transition to the turnaround phase. We prepare a long-term asset management plan to improve performance and enhance future value. If the asset is a short-term hold, we help clients dispose of assets, identify the best brokers in the market, and work hand in hand with the brokers through the sales process and close.
Throughout the stabilisation and turnaround process we communicate regularly with owners and investors. We prepare timely reports that clearly define the critical issues and describe the available remedies. We develop precise recommendations for improving performance and we act quickly to implement appropriate actions.
Our comprehensive approach to turnaround and stabilisation includes all the steps required to organise, manage, protect and improve daily operations, including the following activities.

Lilium GmbH and Lilium Aerospace GmbH: Selling Patent Portfolio
Founded near Munich in 2015, Lilium was developing an electric vertical take-off and landing (eVTOL) aircraft – the Lilium Jet. The start-up company went public on the US technology exchange NASDAQ in 2021. It had around 1,200 employees working on production setup and battery technologies. Overall, it invested some 1.5 billion euros in bringing the aircraft to market, but ran into financial difficulties. Lilium had to file for insolvency in 2024. Mr Ivo-Meinert Willrodt from PLUTA is the insolvency administrator for Lilium GmbH and Lilium Aerospace GmbH. These were involved in self-administration insolvency proceedings from October 2024 and then in regular insolvency proceedings since March 2025 after the sale of the company had fallen through. Mr Wolfgang Bernhardt is insolvency administrator for the holding company Lilium N.V.
The German electric aviation pioneer owned the intellectual property rights. Lilium’s patent portfolio included over 300 patents covering innovations in high-voltage systems, battery management, advanced aircraft design, flight controls, electric engines, propellers and ducted fans for eVTOL aircraft. Mr Ivo-Meinert Willrodt conducted a complex bidding process for the sale of the patent portfolio as part of the insolvency proceedings.
Insolvency administrator Mr Ivo-Meinert Willrodt sold the patents and registered intellectual property rights to Archer Aviation, a US-listed company. The purchase price is in the low to mid double-digit million euro range. After lengthy negotiations in a complex transaction process, Archer prevailed in the bidding. The sale to Archer offers the highest level of transaction and execution certainty. The creditors will also benefit from this outcome.
