How do you build a consistent lead generation framework across channels for your product? What kind of a martech stack do you suggest for beginners?

Answering this based on the context of the question being asked from the POV of a CRM vendor looking to scale: The biggest challenge I've come across is attribution. The framework to drive consistent lead generation really focuses on the mediums, but any marketer is going to test and optimize based on what drives return in their specific org. Those decisions are going to stem from what's working and what isn't. So that portion will fall into place relatively seamlessly. The piece that's a bit harder to solve is confidence in what that data is saying, which is because we're often handed first touch or last touch attribution metrics, which don't really take into account today's buyer journey. So if a CRM could better solve for the overall customer journey and analyze the various touchpoints that a customer takes with a vendor and then weight those touchpoints against how those customers progressed in the funnel, then the data that a marketer would have at their disposal is far more trustworthy. That advanced data set would dictate the tech stack that would be needed. Because absent that, all you can really say is that you need your email, website, and SDR/AE outreach in sync--but there isn't really anything differentiated about that stack.
