A simplified example. Yours is designed from your products, your art direction, and your merchandising rules.
The landscape
We get it.
Nobody shopping for a product customizer is having a good time. Every option on the table asks you to give something up — your product logic, your brand, your timeline, or a slice of every order forever.
We've spent almost 20 years inside DTC storefronts watching brands lose sales to that compromise. So we built a better way: one fixed-price project, designed for your product and your brand, built into your theme as a section your team can edit — done in 14 business days or less, and yours to keep.
See the better way →- 01
The app almost fits
You bend your product around what the app can do — option limits, no conditional logic, a flow that can't handle the way you actually make things.
- 02
It fits, but it's not you
The configurator works and looks like somebody else's software: a bolted-on widget with its own fonts, buttons and modals sitting inside your theme.
- 03
Custom quotes that never end
An agency scopes six months and a number with too many zeros, and you're still paying to change a swatch a year later.
- 04
And the meter never stops
Monthly fees, per-order fees, a cut of every custom sale — the better it converts, the more it costs you.
Examples
Live in the wild.
Real storefronts running custom customizers. Open any of them and configure a product the way a customer would.
JewelryClub Coastal
Charm necklace builder
Pick a base chain, place a center pendant, then build up to eight charms — with live pricing per charm count and a choice of arrangement.
JewelryClub Coastal
Pendant bar
A browsable pendant bar that lets customers mix and match pieces into their own combination before adding to cart.
JewelryAnd Livy
Design your charm necklace
A guided design flow for charm necklaces — chain, placement, and charm selection resolved into a single made-to-order item.
LuggageRoam Luggage
Build-for-you carry-on
A multi-step configurator for shells, zipper, trim, wheels, binding, and handles — shareable via URL and priced live.
QuizRoam Luggage
Custom case quiz
A six-question guided quiz that reads travel style and destination, then routes the shopper to the case configuration that fits.
JewelryAnd Livy
Stack builder
Personalized bangles built to stack — finish selection, live engraving preview with a character limit, and made-to-order handling in the theme.
CollectiblesReal Liberty Copper
Custom coin experience
A collector's flow for a numbered edition — standard or choose-your-serial, a serial number lookup, and price switching inside the product page.

Ledger
The app-store path
Monthly fee forever
You rent the tool that sells your product. It never becomes yours.
Template UI
Their layout, their branding seams, their idea of how your product is chosen.
Their roadmap, their limits
If the app doesn't support your rule, neither do you.
Support queues
A ticket number between you and the person who can fix it.
The custom build
One-time project cost
You pay for the build once. Nothing renews, nothing expires.
Designed to your exact spec
Built into your theme as an editable, manageable section.
Your rules, your logic
Pricing, inventory, and merchandising behave the way you sell.
Direct line
You talk to the person who designed and wrote it.
What we build
Customizers first.
Then the whole decision.
Quiz product finders
Guided recommendation flows that turn browsers into confident buyers, with logic built around how your customers actually decide.
AI shopping assistants
An assistant trained on your catalog and brand voice that answers real questions, narrows choices, and hands off to the cart.
Conversion tooling
Bundle builders, gifting flows, size and fit helpers, PDP rebuilds — whatever the data says is costing you orders.
Jewelry is the specialty. Customizers have also shipped for apparel, luggage, and educational kits — if a customer has to make choices before buying, it's in scope.
Why it converts
Built by someone who optimizes for revenue, not features.
Every tap can lose the sale
Customizers fail on friction: unclear steps, dead ends, slow previews. The build starts from the decision path, not the feature list.
Mobile is the whole game
Most configuration happens on a phone. Controls are thumb-sized, state is always visible, and nothing hides behind a modal.
Speed is a conversion feature
No third-party app bundle loading on top of your theme. Lean code, native to your store.
Clean data downstream
Selections land in the cart and order as structured properties your ops and fulfillment team can use.
Process
The 14-day cycle
Days, not months.
Business days, measured from the end of discovery — not the six-month custom build you've been quoted elsewhere. One person owns strategy, design, and development, so nothing waits in a queue.

Handoff
You get the code, documentation, and a walkthrough. It's yours — no license, no subscription.
What you're promised
The terms, in writing.
Custom work makes people nervous for good reasons. These four things remove the usual ones.
01
Fixed price, agreed up front
Scope and cost are settled before work begins. No hourly creep, no change-order surprises mid-build.
02
You sign off before production code
The design is approved by you first. Nothing gets built against a spec you haven't seen.
03
No discovery fee
The first conversation and the honest read on whether this is the right move cost nothing.
04
Nothing to renew, ever
Code and documentation are handed over at launch. No license, no subscription, no dependency on me.

A good fit if
- You sell on Shopify and personalization is core to the product
- Your current app-based customizer is capping conversion or looks off-brand
- You want to own the code, the experience, and the roadmap
- You have someone who can answer product and merchandising questions during discovery
Probably not if
- You're not on Shopify
- You want the cheapest option rather than the best-converting one
- You need a customizer live this week with no discovery
- You want a monthly-fee app someone else maintains for you

"I surf the web, ride the DTC wave & turn pixels into profits."
Eighteen years dedicated to helping premier DTC start-ups and organizations craft and refine their digital efforts — across ecommerce management, conversion rate optimization, retention marketing, analytics, paid media, and UX strategy. Almost 20 years in total working for and with hyper-growth DTC brands.
That merchant-side experience is why these builds start with revenue questions instead of feature requests. All development happens entirely in Boston, by me — no offshore handoffs, no account manager relaying questions, no agency layers between the decision and the person writing the code.
