Most brands don't have a build problem. They have a vendor problem.
A design shop skins the theme. A freelancer bolts on features. An app vendor owns a fragment. Nobody owns the architecture — so technical debt piles up until a rebuild is the only way out. Carryup is built differently.

When nobody owns the architecture, it rots.
They ship a beautiful theme, then hit a wall the moment you need a custom app, a real integration, or checkout logic. The hard 20% gets subcontracted — or never happens.
Every new requirement becomes another paid app. Five apps later, the store is slow, the apps conflict, and nobody owns how they interact with your checkout and data.
Shopify, your ERP, your PIM, and your CRM each hold a different version of the truth. Inventory drifts, orders fall through, and someone reconciles it by hand every week.
A freelancer here, an agency there, an app dev on the side. Nobody owns how the whole thing fits together — so it accretes technical debt until a rebuild is the only option.
One team. One codebase. One owner.
One engineering team owns the stack
Platform, custom apps, integrations, AI, and CRO — all in one team, sharing the same architecture and the same codebase. When something changes in the store, the people who built the integrations already know. Nothing falls into the gap between vendors.
Architecture before feature code
Every engagement starts with the architecture — data models, integration contracts, and a performance budget — before a feature is built. Decisions are made for how the platform scales, not just how the demo looks.
Shopify-only depth
We don't work on WooCommerce. We don't do Wix. Shopify exclusively — which means we've built things most agencies haven't attempted: Checkout Extensibility, Shopify Functions, headless Hydrogen storefronts, and custom apps that ship to the App Store.
Production standards, not launch standards
A store is production software. We treat it that way — versioned, tested, performance-budgeted, and monitored after launch. CRO thinking is built into how we engineer, not sold as a separate audit.
We start with what's broken
Before we quote anything, we audit your architecture, integrations, and performance — and tell you exactly where the platform is fragile or costing you money. No upselling. No pressure.
A good fit if you're:
