The 10-to-49 majority: half of US growth agencies run mid-size teams
Team-size data across 1,738 US growth vendors shows a market of boutiques and mid-size shops — 82% of firms run fewer than 50 people, and firms above 250 are a 3% sliver.
Across the 1,738 listings in The Wall's index with provider-declared team-size data, the shape of the US growth-services market is unmistakably mid-size:
| Team size | Firms | Share |
|---|---|---|
| Freelancer | 9 | 0.5% |
| 2 – 9 | 524 | 30.2% |
| 10 – 49 | 898 | 51.7% |
| 50 – 249 | 252 | 14.5% |
| 250 – 999 | 50 | 2.9% |
| 1,000 – 9,999 | 5 | 0.3% |
The 10–49 band alone holds 898 firms — a 51.7% majority. Add the 2–9 boutiques and 81.8% of the market runs fewer than 50 people. Only 55 firms in the entire data set field more than 250.
Why team size is a buying signal
Team size predicts the texture of an engagement more reliably than most sales decks. A 2–9 boutique typically means founder-led work and senior attention with capacity risk. A 10–49 firm — the market's center of gravity — means process without bureaucracy, and usually a named team. Above 250, buyers get bench depth and account layers. None of these is better in the abstract; the point of the data is that a buyer can decide which trade-off fits before the first call, and the index publishes the band on every profile that declares one.
How this was computed. Figures are computed from The Wall's index of 2,286 approved, US-based, machine-verified-live listings as of August 3, 2026. Engagement data (rates, minimum project sizes, team sizes, founding years, ratings) are provider-declared figures published on public Clutch profiles and are present for 1,738 of the 2,286 listings; percentages of "disclosed" values exclude listings that publish no figure.
