Why Dropstone?

Independence.  We are neither a subsidiary nor dependent on a single donor. Our analyses reflect the data, not a commercial relationship.

Dual grounding.  A team trained to Swiss scientific standards, operational in contexts where institutional structures are absent or fragile.

Results that get used.  Our deliverables are designed to be actionable: prioritised recommendations, language adapted for decision-makers, practical formats.
