I analyzed 736 Salesforce opportunities by counting how many contacts were associated with each deal and then examined their win-probability. Here are the key insights:

• Deals with 3–4 stakeholders see the highest likelihood of closing:
- 3 contacts: average probability 70.8%
- 4 contacts: average probability 70.3%
• Deals with very few (1–2) or many (5+) contacts perform less well:
- 1 contact: 64.8%
- 2 contacts: 54.1%
- 5 contacts: 64.7%
• The scatter plot “contacts_vs_probability_scatter” illustrates this relationship at the individual-deal level, showing a cluster of higher probabilities around 3–4 contacts.

This suggests that having a moderate number of stakeholders involved is associated with better deal outcomes, whereas too few or too many participants corresponds to lower average win probabilities.
