Most businesses are losing customers they've already won. I fix that.

Revenue retention
About Kyle
The leaky bucket
Businesses pour money into acquisition while customers drain out the back.
You spend to win a customer once, then let them slip away through weak follow-up. Retention is the hole in the bucket — and it's almost always cheaper to fix than to keep pouring more in the top.
Customer Marketing
Turning your existing customers into your best growth channel — speaking to them based on what they actually do, not one blast to everyone.
Existing customers spend roughly 67% more per order than first-time buyers.
Lifecycle Marketing
Mapping the full journey from first purchase to loyal regular, then automating the right message at the right moment across email, SMS and app.
A 5% improvement in retention can lift profit by 25–95%.
Retention Strategy
Finding exactly where and why customers go quiet, then building the system that wins them back before they’re gone for good.
Most ecommerce brands retain only 25–30% of their customers — the rest walk out the back door.
Point of view
“Every business I've worked with could tell me their CAC. None could tell me what it cost to lose a paying customer. That imbalance is why we created RetentionOS.”
Most businesses treat retention like an afterthought — something the email team handles after the “real” marketing budget goes to acquisition. I've spent ten years inside a business that runs on repeat visits, and the pattern is always the same: companies can tell you exactly what it costs to get a new customer, but ask them what it costs to lose one quietly, and most go blank. That gap — between obsessing over the front door and ignoring the back door — is where most of the lost revenue actually lives. I don't think retention is a campaign. I think it's infrastructure. And most businesses are running without it.
I'm building a way to fix this systematically — RetentionOS
A diagnostic and rebuild package for businesses losing repeat customers to weak lifecycle programs. It finds the leaks, explains why they're happening, and hands you a prioritized plan to plug them.
