About the firm
A strategic advisory and private investment firm for founders, investors and institutional counterparties.
We operate where complexity meets capital.
AETHERION Capital is a strategic advisory and private investment firm headquartered in Amsterdam and London, with an office in Zurich. We work with ambitious founders and institutional counterparties to create decisive capital outcomes, whether through structured finance, M&A execution, VC fundraising or operator-led venture building.
Advisory and investment sit under one roof. The firm that prepares a raise, structures a facility or runs a sale also invests, selectively, alongside its advisory mandates. That shapes how we work: we read a mandate as an investor would, and we prepare it to the standard an institution expects.
Three principles
- Mandate-driven
- Every engagement begins with a clear mandate. We align our success with yours, structuring fees around outcomes, not effort.
- Institutional grade
- Our work product, documentation and positioning meet institutional investment standards, from day one of engagement.
- Global reach
- Operating from Amsterdam, London and Zurich, active globally, with focus markets in the Benelux, DACH, the Nordics and the United Kingdom.
How we work with clients
Every engagement begins with a written mandate. It sets out the question, the outcome we are working towards and how our fees relate to that outcome, and it is agreed before any other work begins.
A mandate is carried from the first diagnostic conversation through closing and beyond, along the four stages of our approach. Each stage ends in something written and a decision that belongs to the client.
We are direct about what we see. A recommendation comes with the alternatives we considered and the reasons we set them aside, so that the decisions that belong to the client can be made on full information.
Discretion is part of the work. We do not publish client names or transactions; detailed references are shared under a non-disclosure agreement.
Three offices. Global reach.
We are based on the Keizersgracht in Amsterdam and at 30 St Mary Axe in the City of London, with an office on the Bahnhofstrasse in Zurich. From there we act for clients wherever their capital questions lead, with the Benelux, DACH, the Nordics and the United Kingdom as focus markets.
