Cauvee [call-vay], Here to help you scale! answered:

There's no set right answer. The more people the better the data. Traditionally most sample sizes are 100 people but think about it like this. Which has more power? 90% of 100 or 90% of 1000 all vote in your favor. Which would you pick? My recommendation would be use a sample of at least 100 people. 👊🏽
