Almost a month after Ambitious Air Mobility Group (AAMG) emerged as the latest suitor for what remains of Lilium there is still little public information on who is financing the operation, or on the background of its directors.
Dutch-registered AAMG on 8 August revealed that it was interested in purchasing the assets of the collapsed German electric vertical take-off and landing (eVTOL) aircraft developer and reviving development of the Lilium Jet.
“We are excited by the opportunity to take this platform forward, invest in it, and deliver on its full potential,” chief executive Dr Robert Kamp was quoted as saying.
But AAMG has provided only scant detail about itself. In a 14 August press release related to the interest in Lilium, it calls itself “a European industrial and investment holding company focused on accelerating the sustainable transformation of aviation”.
AAMG, it says, “brings together capital partners, aviation experts, and infrastructure developers to deliver commercially viable advanced air mobility solutions”.
Dutch company registration documents reveal that Ambitious Air Mobility Group – also known as AAMG-NL Holding NV – was incorporated on 8 August 2025, with Robert Jan Kamp and Liza Marjolyn Vraets as directors.
AAMG’s website has for some time described the business as a “a co-operation between AirMobility Inc – Japan and the Ambitious Group”.
On 27 August, AAMG said it had invested an undisclosed sum in AirMobility Inc in exchange for a “significant shareholding” that expands “AAMG’s presence into one of the world’s most strategic advanced air mobility markets.”
Established in 2019, Tokyo-headquartered AirMobility says it is developing an “[infrastructure] platform for safe and secure flying car operations” and has signed multiple agreements with other drone and eVTOL manufacturers.
In the translated version of a press release issued on 19 August, AirMobility Inc said it was partnering with AAMG for the “acquisition and reconstruction” of Lilium.
The links between the companies were further highlighted on 3 September when it was announced that Swiss ground power start-up WattAnyWhere had secured a €20 million ($23 million) investment from “the Ambitious Air Mobility Group (AAMG), which also includes Japan’s AirMobility Inc.”
But the exact nature of the relationship between AAMG and AirMobility Inc is hard to pin down. Are they partners, two halves of a joint venture (JV), or is one now a subsidiary of the other?
AAMG did not respond to FlightGlobal’s questions on its relationship with AirMobility Inc.
Both AAMG and AirMobility Inc have earlier links with Lilium, having signed cooperation pacts with the eVTOL developer prior to the start of its insolvency in 2024.
In fact, AAMG in December last year – when Lilium’s two operating units Lilium GmbH and Lilium eAircraft GmbH were in already self-administration – turned its tentative order for the Lilium Jet into “a binding sales agreement” for eight units, plus six options.
But the Lilium press release refers to the agreement as being with “The Ambitious Group (AAMG), an executive eVTOL operator planning initial operations out of Marbella and Amsterdam”.
It is unclear which company signed the deal with Lilium, bearing in mind AAMG’s incorporation dates from early August.
Declaring its new plans for Lilium’s revival, AAMG said it was backed by €250 million in “committed capital”, with access to a further €500 million.
No details of its backers have been disclosed, although media reports elsewhere have cited the involvement of business jet operator Luxaviation and its eVTOL-focused subsidiary Sigma Air Mobility.
Indeed, an archived version of AAMG’s website even refers to the company as “a JV between Sigma Air Mobility/Luxaviation and The Ambitious Group.”
Neither Luxaviation nor Sigma are strangers to Lilium: the former in 2021 unveiled a wide-ranging partnership to collaborate on the roll-out of airline operations with the Lilium Jet, while in March 2024 AAMG announced a partnership with Sigma for the operation of six jets in the Benelux region from 2026.
Again, the agreement with Sigma appears not to have been with AAMG: marketing materials hosted on the latter’s website reference only UAE company Be Ambitious FZC, which appears to be the registered name for Dubai-based The Ambitious Group.
FlightGlobal understands that although the tentative collaboration agreement with Sigma was signed early last year, little progress was made before it was terminated that September.
While the archived version of the AAMG website says “we are proud to announce a co-operation in 2023 with Lilium and Sigma Air Mobility for exclusive projects with the revolutionary Lilium Jet”, the updated text now reads “we are proud to announce a cooperation in 2023 with Lilium and AirMobility Inc-Japan 2025 for exclusive projects with the revolutionary Lilium Jet”.
Both Luxaviation and Sigma have distanced themselves from the acquisition plans, stating: “Luxaviation and Sigma Air Mobility operate independently of aircraft manufacturers, enabling us to select the most suitable aircraft for each mission without equity ties.
“Any suggestion that Luxaviation and Sigma Air Mobility are involved in the acquisition of, or have taken a stake in, any aircraft manufacturer is incorrect.”
AAMG’s website is also light on detail regarding its ongoing activities. It lists a string of “running projects”, referencing planned city-to-city connectivity networks in the Dutch Caribbean, Europe, North Africa and the UAE for launch later this decade. However, it is unclear how far, if at all, these have progressed.
AAMG did not reply to FlightGlobal’s questions on its progress to date.
In addition, the AAMG website points to agreements with two other advanced air mobility developers, Ascendance Flight Technologies and VoltAero, related to the future operation of their respective Atea and Cassio hybrid-electric aircraft on European routes.
However, as the Lilium Jet would be a direct competitor of the Atea and Cassio on regional routes, it is unclear whether either company will wish to continue with those agreements if AAMG emerges as the owner of a de facto rival.
AAMG did not respond to FlightGlobal’s questions on the continued validity of those agreements.
Detail is also scant on Be Ambitious/The Ambitious Group. Four project areas are listed on its website: the Lilium Jet, waste management, medical services and commodities.
In the latter case, the firm advertises the import of a wide variety of food products from Brazil, even down to sourcing chicken feet for the Chinese market.
Contact details on the AAMG website – www.stayambitious.world – also direct users to another business, Stay Ambitious SL, located in Marbella, Spain.
Spanish company registration documents identify Robert Jan Kamp as the sole partner in Stay Ambitious SL.
Stay Ambitious appears to be one of several European business which Kamp has run.
Notably, the Swiss companies register shows he was a director or chairman of three businesses in that country: Lion Guard Medical AG, E-ScooterWorld Europe GmbH, and New Aventurine GmbH.
Liza Marjolyn Vraets – Kamp’s fellow director in AAMG – is also listed as a former director of New Aventurine GmbH.
All three companies entered liquidation over the course of 2022 and 2023 having only traded for a handful of years. In each case, the liquidation process was discontinued “due to a lack of assets”, the documents show.
AAMG did not respond to FlightGlobal’s questions on the involvement of Kamp or Vraets in running those businesses, the nature of those operations, or the reasons for their closure.
Meanwhile, the potential acquisition of Lilium’s assets from administrator Pluta appears no closer to completion.
“We are conducting discussions and negotiations with interested parties regarding the sale of Lilium as a whole or the sale of individual assets,” says insolvency practitioner Ivo-Meinert Willrodt.
“The requested proof of purchase price financing has not yet been submitted. This is an important prerequisite for the purchase contract negotiations. This is a standard procedure. We cannot disclose any further details.”
Despite this, AAMG does appear committed to reviving the Lilium Jet, having in mid-August announced that it had signed a rental agreement for facilities at Oberpfaffenhofen airport in Bavaria, Lilium’s former home.
Kamp says AAMG has agreed a four-year lease, with provision for a two-year extension.
Meanwhile, Pluta has sold Lilium’s former battery production facility at Oberpfaffenhofen to electric aircraft developer Vaeridion.
Lilium entered insolvency last autumn after running out of cash. An attempt to sell the business to investment vehicle Lilium Aerospace failed earlier this year due to a lack of funding, leaving the assets of Lilium GmbH and Lilium eAircraft GmbH controlled by the administrators.
