Uncover Critical User Needs, Live and In-Product

I launched my M.L.P (Minimum Lovable Product), a user research platform to help product managers test assumptions with users (on-demand), probe for critical user needs and design user-centric products, mainly through in-product live user interviews. My initial user segment is: Product Managers at growth stage startup in the UK I've been doing founder-led sales on LinkedIn and cold emails is anyone interested in jumping on a 15-call with me, this or next week? I'd like to understand your experience doing user research.
