Klaviyo Shopify

Your ads bring subscribers in. Klaviyo should keep them.

Kei Nakayama  ·  Los Angeles, CA

Every subscriber who churns cost you money to acquire. Then you spend again to replace them. Most Klaviyo setups weren't built for subscription retention. I fix that. Lower churn means your acquisition budget compounds instead of treading water.

What I see constantly

The same three gaps
at nearly every brand.

These aren't edge cases. They show up at brands doing $1M and brands doing $10M. Fixing them is usually worth more than your next month of ad spend.

They came in with high churn, no cancellation flows, and acquisition costs eating into margin because subscribers weren't sticking. The two things that moved the needle: an extensive post-purchase flow that walked new subscribers through exactly how to get value from the product, and an educational campaign series that built habit and reinforced the subscription before customers ever thought about cancelling. Churn dropped from 15% to 9%. LTV climbed. That freed-up margin went back into paid acquisition. That's how 30 subscribers became 300 in twelve months.

Full-cycle Klaviyo,
built for subscription.

How it works

Simple to start.
No retainer required.

Kei Nakayama Why I do this

I tried to build
one of these brands.

A few years ago, I tried to start a pre-made food subscription in Japan. I got far enough to understand what it actually takes. The sourcing, the packaging, the logistics, the relentless problem-solving before a single order ships. I couldn't build a product I was proud enough to sell.

That experience changed how I see the people I work with. The founders who do make it — who find something worth subscribing to, build a brand around it, and keep showing up — I have a lot of respect for that. Most people don't understand how hard it is until they've tried and fallen short.

What I do now is a different kind of problem. Once a brand has a great product, the work becomes keeping the people who find it. That's where most Klaviyo setups quietly fall apart. Not because the brand isn't good enough. Because the email infrastructure wasn't built to support how subscription customers actually behave.

I work with founders who have already done the hard part. My job is to make sure their retention side is working as hard as they are — so their best customers stay, and they can stand out in a crowded market on the strength of that loyalty.

"Kei didn't come in with tactics or hacks. He took the time to understand how our subscription model actually works and built a setup that made sense for sustainable growth — not just short-term wins."
