How do you currently find out where your landing page is losing signups?

Genuine question for other founders here — when your signup numbers are lower than they should be, how do you actually diagnose why?

  In my experience the usual playbook (Hotjar recordings, asking friends to "try it," A/B testing headlines) either takes forever or gives you opinions instead of a first-time-visitor's actual experience.

  Nobody on your team can un-know your product long enough to see it the way a stranger does.

  I've been building coldrun to solve exactly this — an AI agent that visits your product cold, with zero context, finds your primary CTA, tries to complete it, and reports back exactly where it hesitated

  or gave up. No prior knowledge of your product, no script, just a fresh pair of (synthetic) eyes.

  Curious how others here handle this today — do you rely on user interviews, analytics funnels, gut feel? Would love to compare notes before we launch.
