This is one of the best examples of social proof I've seen in most SaaS companies' websites, here's why:

1) They explain the benefit for each person using the product. Seems like EVERY USER wins.

2) The testimonials focus on results potential customers can generate -> "millions in compounding gains" and "have delivered a 67x return"

3) They mention the reasons their customers switched from their competitors because chances are that visitors are currently using the competitor's tools and they want to understand why is ChurnBuster better.

4) They mention somewhat big/well-known SaaS companies in their social proof.

Spot on from ChurnBuster... SaaS Companies, take notes!
