Top 6 startup investors in Luxembourg, ranked by recent fund activity
Among firms with a published profile and a dated fund or deal in the last 24 months. The rule: Activity score out of 100: recency of the latest fund filing or dated deal (50: full marks within 3 months, then stepping down at 6, 12 and 24 months), size of the fund on file on a log scale (35) and completeness of the public record (15). It is a measure of activity and fit, not of quality or returns. The same rule orders the whole list; it is repeated in the method box.
