Switzerland: Boutique consulting firm AJL Atelier has hired Travis Callahan as its new partner, president, and head of M&A [mergers and acquisitions].
With over 25 years of experience, Callahan has founded and successfully sold companies, and managed over €30 billion in high-profile venture capital tech, M&A, and restructuring transactions. He is a US bar-qualified lawyer and holds an impressive academic background, including a Trium Global Executive MBA, a Juris Doctorate, and Master’s and Bachelor’s degrees.
His previous roles include serving as chairman of the board, co-founder and president at Ignatica, founder and executive chairman at Milon Capital, and founder and president of Green Wave Capital.
Beyond business, Callahan is an avid outdoor enthusiast, having climbed Mount Kilimanjaro, voyaged to Antarctica and dived in the Galapagos Islands. He is also committing to making a positive impact in the world, devoting time to enriching the lives of underprivileged children through his work with homes and schools for orphaned children in Africa and summer camps for youths in the United States.
Callahan will be tasked with helping to scale, professionalise and solidify AJL Atelier’s position as a leading M&A, financial advisory and consulting / research practice globally, with a clear focus on the short-term / vacation rental industry, which represents a substantial 14 per cent of the global hospitality market. He will support Cristina and Simon Lehmann who have spent the last seven years building the consulting and advisory authority in the short-term rental space.
The hiring of Callahan is the latest new addition to the AJL Atelier team, which has also formed strategic partnerships with Cambon Partners, Key Data and Raincatcher in the last two years.
