Ask HN: B2B SaaS Onboarding flow Free to try with/without CC?

Hi we are getting ready to launch our first self onboarding flow at Twig.so. I love the idea of customers understanding what we do and getting started self serve without a "Book a demo". My big question today is should I 1.) Place a stripe CC paywall with a 30 day trial? 2.) Allow users to try out the product with you using a credit card and then show warnings closer to 30days.

I have not done this before. So looking for advice on what works and what doesnt and any learnings you may have.

My goal is to accelerate the speed at which good customers(Customers that have a need for our product) try out the product and start paying for a service they deem valuable.

Please share your thoughts in detail. I looking for deep insights and learnings from your experience.
