How do you know if a new user is a potential customer?

I'm currently working on a survey to explore how SaaS companies understand if a new user is a potential customer, and I need your insights! I've put together a super short survey that'll take just a couple of minutes to complete, https://form.typeform.com/to/enBTu1nY Once the survey is complete, I'll prepare a comprehensive report to share our findings with this amazing community. Additionally, if you or your company would like to be featured in the report, just let me know in the survey!
