At Storyclash I did new business across DACH and Europe, the full cycle myself: outbound, discovery, demos, POCs, procurement, negotiation, closing. Value based selling, hard qualification with MEDDICC, a clean forecast in the CRM (HubSpot), no gut feeling. And what customers told me didn't die in the CRM, it went back into the product.
Same story at presono before that: 50+ full cycle deals, around €1.25M ARR. Not a one off, it's repeatable. MarTech is what I know deepest, but the method works in FinTech and other B2B SaaS categories too, when the product has real buyer fit. And if a product doesn't have it, I'll tell you before you spend money.
