@djmc no training or resource suggestions, I’m sure you’ll get plenty of those.
Here’s my advice if you’re in b2b, starting out and come from the technical side: get to know who sells your product and how they do it.
Learn how your funnel gets filled, learn where and why it leaks. You might be surprised how little of your success or failure has to do with product or what knobs and dials you can actually turn with something that seems inconsequential without a full perspective.
