Mostly use internet to connect to partners, brokers, find deals in finance like real estate lending business funding etc.
I just signed up as an affiliate for a great product for startups (which I will advertise here when I can, few more posts!) and will be looking to create a youtube/blog/instagram etc around it. I might create a brand around my journey in business, and use that to sell my affiliate products and get leads. For example they might apply through my startup funding affiliate to get cash to invest in their business start up, and i would help them with an online business (resell services like SEO, ad management, etc)
Or I would set them up to do lead gen or cold calling for me. Big plans day by day tiny steps. Imagine if could get someone startup momey to do lead gen, but then I owned part of that company and all the leads were mine? Thatd be sick lol
