The Magical Quadrant

The four quadrants explained
Each card shows the count of firms in that quadrant and the top 5 by composite score.
Strong execution but broader service mix. High-quality generalists - good fit if your project crosses multiple disciplines in one engagement.
Deeply specialised but with moderate market presence. Often the right pick when specialisation matters more than scale - boutique shops with deep technical chops.
Newer entrants and smaller boutiques. Higher risk but often the best price-performance - particularly for early-stage startups or non-mission-critical projects.
