Back up your offer with compelling numbers to make people trust you. It's needless to say that all these numbers must be real!

The Round Number Bias tell us that people prefer rounded numbers over numbers that aren't.

However, "ugly" non-rounded numbers are better to build trust since they look (and hopefully are) more honest.

For example, you can say that you have 1000 examples but it looks far more honest to say 1178, as SaaSFrame does.
