Industry Contenders
Top-left · Y ≥ 50, X < 50

Strong execution but broader service mix. High-quality generalists - good fit if your project crosses multiple disciplines in one engagement.
Market Influencers
Bottom-right · X ≥ 50, Y < 50
2FIRMS
Deeply specialised but with moderate market presence. Often the right pick when specialisation matters more than scale - boutique shops with deep technical chops.
Upcoming Achievers
Bottom-left · Both axes < 50
31FIRMS
Newer entrants and smaller boutiques. Higher risk but often the best price-performance - particularly for early-stage startups or non-mission-critical projects.
