Optimizing Customer Expansion for B2B SaaS

More than half of net new revenue last year came from existing customers. Yet most companies still treat expansion as a side effect of good relationships instead of a deliberate, measurable motion with its own process, capacity plan, and target list. The reason is simple: expansion is harder to measure than new business. There's no clean CAC payback formula for convincing your CFO to fund more CSMs, and the whitespace data your reps need to have intelligent conversations is probably sitting in a backend system they've never seen. In this episode, Eddie Reynolds and Rachael Bueckert break down how to build a real expansion engine, starting with why ICP needs to account for retention and expansion potential and not just acquisition ease. The conversation covers how Salesforce doubled customer spend within the first 12 months and the playbook behind it, product and stakeholder whitespace analysis, how to build a capacity plan for expansion the same way you would for new business, and why the crawl-walk-run version of customer health scoring is a CSV and a red-yellow-green column.
