Hover any bubble for the firm's exact scores. Filter the view using the controls on the right.
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.
