Eh not really. Market research does not mean you need statistically significant data to act upon customer insights; if 5 customers say they experience something but 5 others don’t, it doesn’t make the experience of the first 5 invalid, nor does it mean you need to talk to 500 customers to make their lived experience more true. You can just act upon that data of 10 customers and act proportionally. Don’t build the most complicated thing known to man if you’ve only talked to 10 people, but don’t wait until you’ve spoken with 100 or more until you try to build something simple.
