Revenue & Operational Impact
This opacity directly tanks your GTM efficiency metrics. You can't calculate true CAC by channel, so you overspend on low-ROI campaigns while starving high-performing ones. Your LTV:CAC ratio can look healthy in aggregate while the channels actually driving it go underfunded - and you'd never know which ones. Sales and marketing alignment suffers because reps claim credit for deals Marketing nurtured for six months, and pipeline conversion stalls with no way to tell which stage is leaking. Every quarter, you justify marketing spend to the CFO with incomplete data, and every quarter, budget gets cut.
