Klaviyo Shopify

You work hard to bring customers in. Klaviyo should keep them.

Kei Nakayama  ·  Los Angeles, CA

Every customer who churns cost you money to acquire. Then you spend again to replace them. Most Klaviyo setups weren't built for 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 win-back flows, and acquisition costs eating into margin because customers weren't coming back. The two things that moved the needle: an extensive post-purchase flow that walked new customers through exactly how to get value from the product, and an educational campaign series that built habit and reinforced the brand before customers ever thought about leaving. Churn dropped from 15% to 9%. LTV climbed. That freed-up margin went back into paid acquisition. That's how 30 active customers became 300 in twelve months.


What I do

Full-cycle Klaviyo,
built for retention.

Already on Klaviyo? Here's the work. Not yet? I'll help you decide if it's time to move — and handle the migration if it is.


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 meal-kit brand 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 coming back 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 returning 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.
