Exploring B2B Opportunities: Seeking Cold Email Referrals

Hey everyone, not sure if this is the best place for this (lmk if not and I'll move it), but wanted to ask the community something. I primarily work with SaaS founders helping them build complete cold email infrastructures, everything from purchasing domains to writing scripts to setting up deliverability... all that good stuff. They pay once, own the entire system forever instead of paying agencies thousands monthly. Been thinking about exploring other B2B industries since the system ownership model seems to resonate across verticals. Plus, the technical work is identical- the infrastructure that sends 1000+ emails daily is the same whether you're selling SaaS or logistics software etc haha. Anyone here know founders in other B2B spaces who might be interested in this approach? Logistics, fintech, consulting, whatever. Happy to send $500 your way for any intro that works out. Cheers!
