I started SUM Digital to help ambitious B2B companies stop accepting inconsistent pipeline. For years, I watched the same pattern: capable products, happy customers, decent NPS, yet growth that depended entirely on the founder to close the deals. I wrote this playbook to hand you the decision framework most agencies keep for themselves.
One motion. Done well. That’s where it starts.
