01 — The ranking

The Madrid Corporate & M&A board

A tier on this Madrid Corporate & M&A board names relative firm standing in words. Placement speaks to M&A and corporate advisory presence; order inside each band carries no hierarchy and is not a score.

Methodology

How tiers are assigned

Deterministic public-footprint core (local depth, practice share, seniority mix, public hiring momentum), computed relative to this market's own distribution. Tier placement is derived from this public mapped data; a per-firm public-source ledger is compiled for firms in the annual research pass and applies to those firms' factual claims, not to tier membership. No third-party legal-directory bands are used as an input.

Market scope

5–9 firms earn a tier in Madrid within this scope (banded).
