About Albert Achammer
Albert Achammer is an architect and the CEO of ATP architekten ingenieure, a European integrated design firm founded in Innsbruck in 1951. He holds a Master of Science in Architecture from ETH Zurich and an MBA from IESE Business School. Before ATP he worked at gmp (von Gerkan, Marg und Partner).
He joined ATP in 2020 as a partner and board member, and he founded and led the firm's Hamburg office. Since July 2025 he has been chief executive of the ATP group. He succeeded his father, Christoph M. Achammer, who stayed on as chair of the supervisory board. His LinkedIn profile lists Vienna as his location.
The only angel investment we found in public sources is Phase0, in 2026. Press coverage of that round names him as a business angel. A German press release says he brings industry expertise to Phase0 without taking an operating role.
We found no public record of other angel investments, a fund, or a stated investment thesis. Crunchbase and CB Insights each list him as a co-investor in the Phase0 round.
Phase0 closed a seed extension of EUR 2.6M (about $3M on the Lounge deals desk), announced in September 2026. Realyze Ventures led the round, and Ershad Jamil, a former Chief Growth Officer at ServiceTitan, joined as a business angel alongside him. LocalGlobe and Atlantic are existing investors.
Phase0 was founded in Berlin in 2020 by Matthäus Kerres. It is a browser-based platform for tendering, billing, fee management and construction supervision, used by architecture and engineering firms in the DACH region. The new capital goes toward AI agents that automate administrative work. The sources do not say how much Achammer invested.
The public record is too thin to define a stated focus. His one known investment is a seed-stage, vertical AI software company in architecture, engineering and construction (AEC), a field he works in as an operator. He has also said publicly that AI will affect planning and design work and that ATP uses technology to automate repetitive tasks. Check size and any stage or geography preferences are not public.
