The collapse and potential revival of Lilium, a leading German electric vertical takeoff and landing (eVTOL) aircraft developer, has sent shockwaves throughout the advanced air mobility sector. Once a beacon of European aerospace innovation, Lilium’s journey from raising €1.5 billion to filing for bankruptcy twice within four months highlights the precarious position of eVTOL Startups in a rapidly evolving but capital-intensive industry. The emergence of Ambitious Air Mobility Group (AAMG) as a potential investor, with a declared €250 million secured and access to a further €500 million, underscores both the technological promise and financial volatility that define this emerging market.

This article examines Lilium’s history, the factors behind its insolvency, and the significance of AAMG’s intervention. By situating these developments within the broader context of the global eVTOL and air taxi market, we aim to provide a neutral, fact-based assessment of the risks, opportunities, and lessons for stakeholders in advanced air mobility.

As the urban air mobility sector is projected to grow from $4.59 billion in 2024 to $23.47 billion by 2030, Lilium’s fate serves as a test case for the viability of European ventures in a fiercely competitive, high-stakes market.

Historical Background and Company Origins

Lilium was founded by graduates of the Technical University of Munich a decade ago, with a vision to revolutionize urban transportation using electric aviation. The company quickly positioned itself at the forefront of the eVTOL movement, developing the Lilium Jet, a distinctive aircraft designed to address the growing congestion in metropolitan areas through regional air mobility.

Early investor confidence was strong. In March 2020, Lilium raised $240 million in a round led by Tencent, with support from Atomico, Freigeist, and LGT. This was followed by a SPAC merger with Qell Acquisition Corp in September 2021, resulting in a NASDAQ listing and further capital influx. Throughout its journey, Lilium attracted approximately €1.5 billion in funding from both European and international sources.

Organizationally, Lilium transitioned from a startup to a more mature aerospace Manufacturers, with notable leadership changes such as the appointment of former Airbus CEO Tom Enders to the board and the recruitment of Klaus Roewe as CEO in June 2022. These moves were intended to bolster the company’s ability to navigate the regulatory and operational hurdles of commercializing eVTOL technology.

Technology and Product Development

The Lilium Jet stands out for its use of electric ducted fans, diverging from the open rotor or tiltrotor designs of many competitors. The aircraft is designed to carry six passengers plus a pilot, achieve a cruise speed of 250 km/h, and cover a range of 250 km. Its distributed propulsion system uses 36 electric vectored thrust fans, promising reduced noise, about 6 dB(A) quieter than helicopters at 100 meters, and increased operational efficiency.

Operationally, the Lilium Jet’s 45-minute charging time and compact footprint make it suitable for high-frequency, regional city-to-city operations. The aircraft’s design was intended to minimize infrastructure requirements and maximize utilization, critical for the economics of air taxi services.

Despite technical advances, Lilium faced significant delays and cost overruns. The first manned flight, initially slated for spring 2024, was postponed due to technical and regulatory challenges. Nonetheless, the company made progress in safety testing, such as the successful nose landing gear drop test in November 2024, witnessed by compliance engineers as part of the certification process.

“The Lilium platform is the result of years of endeavour by some of the most talented engineers in the world. The technology developed in Bavaria is groundbreaking and both technically and economically feasible.” — Dr. Robert Kamp, CEO, Ambitious Air Mobility Group

Financial Trajectory and Investment History

Lilium’s capital-intensive development required ongoing fundraising. The company’s largest recent raise came in July 2023, with $192 million from German tech investors, institutional backers, and Tencent affiliates. This round was structured through a mix of public offerings and private placements, reflecting the complexity of funding advanced aerospace projects.

Despite these efforts, Lilium’s available resources fell short of the estimated €300–500 million needed to reach type certification in 2026. The company’s international structure, parent listed on NASDAQ, subsidiaries in Germany, headquarters in the Netherlands, provided access to multiple markets but complicated insolvency proceedings.

The funding gap became acute as development costs rose and regulatory timelines lengthened, setting the stage for the financial crisis that followed.

The Dual Bankruptcy Crisis

Lilium’s first insolvency filing in October 2024 was triggered by the German government’s refusal to provide a €50 million loan guarantee, which would have unlocked matching funds from Bavaria. This decision, rooted in concerns about investment risk and the role of public funding in private ventures, left Lilium unable to access €100 million in critical support.

The immediate consequence was the layoff of approximately 1,000 employees and the suspension of operations. A rescue attempt emerged in December 2024, when the MUC Mobile Uplift Corporation (later Lilium Aerospace) pledged over €200 million to retain 775 jobs and resume development. However, this deal collapsed after key investors failed to deliver, notably a €150 million commitment from Marian Bocek that never materialized.

The failed rescue left employees unpaid for weeks, prompting a GoFundMe campaign to support those affected. In February 2025, Lilium filed for bankruptcy a second time, highlighting the human and technological costs of financial instability in the sector.

“The risk for the federal government is far too high. If Bavaria wants to take on this subsidy, then it should do so alone.” — Frank Schäffler, FDP, German Parliament

The Ambitious Air Mobility Group Emergence

In March 2025, Ambitious Air Mobility Group (AAMG) announced plans to acquire Lilium’s assets, including intellectual property, facilities, and key personnel. AAMG claims to have secured €250 million, with access to an additional €500 million, aimed at stabilizing and relaunching the Lilium platform.

AAMG is a partnership between AirMobility Inc. of Japan and The Ambitious Group, with additional ties to VoltAero and Ascendance. The group had previously ordered 16 Lilium aircraft, demonstrating prior commercial interest. Their strategy includes retaining technical and certification teams, recognizing that much of Lilium’s value lies in its engineering expertise and regulatory relationships.

The AAMG proposal also emphasizes international expansion, particularly through collaboration with Japan’s AirMobility Inc. This reflects a recognition that future eVTOL success will require access to global markets, not just European operations.

Market Context and Industry Dynamics

The global urban air mobility market is expected to grow from $4.59 billion in 2024 to $23.47 billion by 2030, with air taxis leading the growth. Factors driving this include urban congestion, advances in battery technology, and increased investment in supporting infrastructure. The air taxi segment, in particular, is seen as the most promising for near-term commercialization.

However, growth projections have been revised downward by 0.4% due to trade tensions and tariffs affecting key components, such as lightweight composites and avionics. These economic realities pose additional challenges for companies seeking to bring eVTOL aircraft to market.

Regional disparities in government support are also significant. U.S. and Chinese companies benefit from substantial public and defense funding, while European firms like Lilium and Volocopter have struggled with less direct support. This has raised concerns about Europe’s competitiveness in the global eVTOL race.

“The urban air mobility market’s compound annual growth rate of 31% demonstrates strong investor interest, but also highlights the high risks and capital demands facing eVTOL developers.” — Aviation Week

Regulatory and Government Policy Impact

The German government’s refusal to back Lilium’s loan guarantee was a decisive factor in the company’s collapse. The debate revealed deep divisions about industrial policy and the appropriate use of public funds to support innovation. While Bavaria was willing to contribute, its support was conditional on federal participation, which did not materialize.

On the regulatory front, Lilium maintained compliance with the European Union Aviation Safety Agency (EASA), and its certification progress remains a valuable asset for any successor. However, the complexity of achieving certification across multiple jurisdictions remains a major hurdle for all eVTOL companies.

Comparisons with the U.S. and Asia highlight the importance of coordinated government support, which has been a key factor in the success of competitors like Joby Aviation (backed by Toyota’s $500 million investment) and various Chinese entrants.

Global Competitive Landscape

The global eVTOL industry is highly competitive, with American and Asian companies generally enjoying more robust government and private sector support than their European counterparts. Lilium’s struggles are mirrored by those of Volocopter, another German eVTOL developer that filed for insolvency in December 2024 but continues to operate under provisional proceedings.

Lilium’s technology, based on ducted fans, distinguishes it from competitors using multicopter or tiltrotor designs. This diversity reflects the ongoing search for optimal solutions in a nascent industry. Lilium’s focus on longer-range, regional mobility contrasts with the short-hop urban approach of many rivals, but also required more advanced technology and longer timelines.

Despite reporting approximately 780 orders and reservations, Lilium’s financial woes led to order cancellations, such as ASL Group’s withdrawal of its reservation for six jets. The ability to convert early interest into revenue remains a challenge for all players in the sector.

Future Prospects and Strategic Implications

AAMG’s proposed acquisition of Lilium’s assets could serve as a model for preserving high-value aerospace technology in the face of financial distress. The plan to retain key personnel and continue certification efforts is critical for maintaining momentum and leveraging Lilium’s existing progress.

Success will depend on AAMG’s ability to manage technical, regulatory, and commercial risks. The group’s €750 million funding plan appears robust, but the timeline for certification and commercialization remains tight. International partnerships, especially in Asia-Pacific, could provide the scale and revenue needed for long-term viability.

The Lilium case also raises broader questions about Europe’s industrial policy and the need for public sector support to compete globally. As the sector grows, aligning public and private interests will be essential for fostering innovation and maintaining technological leadership.

Conclusion

The financial collapse and potential rescue of Lilium encapsulate the promise and peril of the eVTOL industry. Despite technical achievements and substantial investment, the company’s fate was determined by a combination of regulatory, financial, and market challenges. The emergence of AAMG as a potential savior offers hope for preserving Lilium’s technological legacy and for continued European participation in the advanced air mobility sector.

Ultimately, the Lilium story highlights the need for coordinated public and private sector strategies, robust funding, and international collaboration to realize the full potential of eVTOL technology. The outcome of the AAMG acquisition will shape industry approaches to managing technological assets and corporate distress, with implications for stakeholders across the global aerospace ecosystem.
