Cold calls, cold emails, cold linkedin, etc. - the list goes on. Personally, building Refer Me (https://www.refer.me/), the best way I've found getting to know folks on the B2B side is by offering them a free month of premium to chat for 15 minutes because many of the referrers are B2B decision makers. You get to know your customers pain points as a default by chatting with them, but also have an opportunity to pitch the value of the B2B direction you're going. Would love to hear other interesting avenues y'all have explored :)
