About Needle Movement
01Who we are.
Needle Movement is an email and retention practice for Shopify DTC brands, founded in Brooklyn in 2015 — before most of today's retention agencies existed.
It's built around one principal, Stephen Carl, who works every account, backed by part-time specialists on execution. No account managers, no layers, no hand-off after the contract signs. The person you meet is the person who does the work.
02Where it comes from.
Stephen has spent 25+ years in DTC — starting as employee #5 at Kozmo, the Amazon-backed startup delivering orders in under an hour, years before Amazon itself figured out how.
The lesson wasn't subtle: the highest-margin growth doesn't come from the next ad channel — it comes from customers you already have.
Since 2015, over 50 DTC brands have trusted Needle Movement with that thesis. The ceiling of what's possible shows in stories like Ecru, which grew from $500K to $2.9 million in annual DTC sales — triple-digit growth, again. Different brand, same thesis.
03How we work.
The method lives inside Klaviyo — over ten years of daily work in the platform, through every pricing change, editor rewrite, and deliverability shakeup since it was a scrappy Boston startup.
The expensive problems in an account are rarely loud: a flow quietly excluding buyers, dead profiles padding the bill, a popup that's been leaking new subs for months. We know where they hide because we've seen them hide in account after account, year after year.
AI has changed the tempo of that work — the analysis that used to swallow weeks of spreadsheets now takes days — but the judgment about what the data means still comes from those ten years of daily work inside Klaviyo. That's where the experience earns its keep.
Our services are built around named problems, some focused, some running alongside your team for a quarter or more. Some clients need us for eight weeks; some have kept us for years.
04Off the clock.
Stephen lives in Brooklyn with his wife. He's been in DTC long enough to have outlived Gilt Groupe, Magento, and at least four email platforms that swore they'd bury Klaviyo. He still gets more animated about lifecycle marketing than any dinner guest should.
Occasionally, someone hands him a microphone on purpose — below are a few of those appearances:
