Built a B2B workflow automation tool - How to Market, find PMF and make some traction? [I will not promote]

Hey everyone 👋 Need your expert GTM advices. As a consultant/contractor, I've been working with several companies in regulated domains over the last decade. I've noticed they're struggling with similar problems, around application processing / onboarding. Most are using a mix of: * Email chains for document collection * Various forms - Google, Type, Paper, PDF * Manual work with multiple internal/external systems These are more prominent in Financial and Healthcare domains, specially SMEs. As a techy working for over 24yrs, I couldn't stop my itch. And started to build a B2B solution: * Visual workflow builder (drag-and-drop) with integrations and few other automations support * Application builder (json directed forms, Files upload etc.) * Document generation from templates * Task automation & routing for employees/agents * Audit trails and rule-engine for compliance (was thinking about regulated domains) * Integration capabilities (API/Webhooks) * Multiple web fronts (Customer portal, admin console etc.) Here, I broke all the startup best advices.- validate first, niche-down, get paying customers before you build it etc etc. Must confess - I've worked out of my passion mostly. But... now I think it's really an usable solution for "many" industries. From my experience, I know it'll be close to impossible to get Financial businesses onboard without SOC 2 cert. Healthcare will need HIPAA cert. But after putting so much effort into it, don't want to give up. So, am asking the community for advice, GTM strategy and how can I effectively find PMF? Thanks so much in advance!
