About Dropstone
Independent advisory in water, geosciences and complex contexts. Bridging scientific standards with operational field intelligence.
Independent & Specialized
Dropstone is an independent advisory firm based in Geneva, specialised in water-related issues, geosciences and complex situation management.
Founded in 2013 by Patrick Kilchenmann, geologist and hydrogeologist by training, the firm has developed a dual expertise: a strong technical grounding in applied Earth sciences in the Swiss context, and a confirmed operational capacity in some of the world’s most challenging humanitarian and development environments.
What unites us across these two worlds
“The conviction that the best decisions arise from the combination of analytical rigour, field understanding and independence of judgement.”
Key Strengths
What sets us apart
Dropstone is not a large generalist firm. We are a human-scale organisation with a network of senior consultants recognised in their fields.
This allows us to:
- Rapidly mobilise highly specialised profiles without structural overhead.
- Maintain a high level of personal expert involvement on each mandate.
- Guarantee full independence from suppliers, donors and operators.
Methodology
Our approach
We deploy rigor, continuous triangulation, and structural integrity to offer outputs directly adaptable to operational deployment.
We are dedicated to:
- Understand the real context — institutional, technical, political.
- Work rigorously and critically with available data.
- Produce deliverables directly usable by decision-makers.
