Team sizes at marketing consulting firms in Missouri
75.3% of Missouri's marketing consulting firms with employees had fewer than five people in March 2023, compared with 83.6% nationally. 84.4% had fewer than ten. At that size the phone is shared, so routing (who rings, when, and what happens after hours) matters more than the number of desk phones.
| Employment size | Establishments | Share | U.S. share |
|---|---|---|---|
| 1–4 employees | 463 | 75.3% | 83.6% |
| 5–9 employees | 56 | 9.1% | 7.2% |
| 10–19 employees | 51 | 8.3% | 4.3% |
| 20–49 employees | 29 | 4.7% | 3.1% |
| 50 or more employees | 16 | 2.6% | 1.8% |

- The consultant calls a client to review results.
