What to Measure (and What to Ignore)
CAC:LTV ratio (target 1:3+), new customer revenue attribution by channel, blended ROAS, and brand search volume growth (indicator of upper-funnel success beyond last-click metrics).
What Not to Do at This Stage
Don't spend Series A budget on broad TV/OOH before digital channels are maxed out. Don't let creative fatigue creep, refresh ad sets every 3-4 weeks. Don't lose track of unit economics in the excitement of scale.
The Founder Trap
Hiring a 5-person in-house marketing team before a 2-person growth team with external creative support would yield 3× the results at half the cost. Stay lean on headcount, heavy on creative testing budget.
How to Use FluxNote at This Stage
