Between Health was building fast but had no real acquisition infrastructure — no conversion tracking, inconsistent lead quality, and a CAC problem that threatened their unit economics. I stepped in as a strategic partner, helping the founding team get clear on their growth model, build the measurement foundation from scratch, and design a paid acquisition system aligned with their LTV targets. CTR nearly doubled from 2.96% to 5.87%, conversion rate hit 4.9%, and CPA came down to $42.40.
