The four quadrants explained
Each card shows the count of firms in that quadrant and the top 5 by composite score.
Industry Contenders
Top-left · Y ≥ 50, X < 50
10FIRMS
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
37FIRMS
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
92FIRMS
Newer entrants and smaller boutiques. Higher risk but often the best price-performance - particularly for early-stage startups or non-mission-critical projects.

How firms are placed on the matrix
Every position on this chart is the output of the Goodfirms ranking algorithm - a weighted composite of signals across two axes. The algorithm is recomputed regularly and is fully documented.
Sponsorship does not affect placement. PRO members receive visible badges and ad placements, but their algorithmic scores are calculated identically to free listings.

Missing signals are excluded from a firm's score, not substituted with defaults - weights redistribute across remaining inputs
4
Recency decay over the last 18 months keeps stale reviews from dominating
