Sifted has published an analysis of the professional services firms that work with Europe's 250 fastest-growing startups. The report spans banks, law firms, accountancies, and PR agencies, shedding light on the behind-the-scenes infrastructure of the region's high-growth economy.

By tracking which firms are most commonly engaged by these startups, the analysis provides a practical reference for founders seeking advisors. It also illustrates how the market for such services is structured around a relatively small set of established players, though the exact rankings depend on Sifted's methodology and selection criteria.

Because this is a single source, there is no independent comparison to other rankings. The findings should be read as one snapshot of the advisory landscape, not a definitive measure of all professional services activity in Europe.
