Using AI to pre‑test GTM for clients

I do some early‑stage GTM work for SaaS founders as I am working in a services company and I’m experimenting with adding an “AI simulation pass” before we lock anything in.

Example: I’ll map out ICP, positioning, pricing hypotheses, and a cold email / landing page.

Then I’ll run that through a tool like RightSuite that simulates buyer reactions and highlights where people might be confused, price‑sensitive, or indifferent.

I’m treating it as one more input, not the actual truth.

For those mentoring founders on marketing: have you tried tools like this in your process?

Did they actually help you refine GTM?
