Upgrade Ecommerce to Headless
A faster storefront on the platform you already run.
Going headless does not mean replatforming. We keep your store's back office for products, stock and orders, and replace only the storefront customers see with a fast custom front end. Shopify moves to Hydrogen, Shopify's own headless framework, or Astro; BigCommerce to Catalyst, its own headless storefront, or Next.js; Magento, WooCommerce, PrestaShop, Medusa JS or commercetools to an Astro or Next.js front end using the store's own interfaces — with product stories and landing pages edited in Sanity.

KeboolaReplatform the whole store in one project.
Move from a traditional store on one platform to headless on another, with data, redirects and search carried across.
Replatform your storeGenerative, RAG and Agentic
Three different things — most businesses need more than one.
A storefront built separately from the platform that holds products, stock and orders, connected through the platform's own interfaces.
When you need it: The customer-facing pages can be made faster and more flexible without moving the back office.
A stack where each part — catalogue, checkout, search, content — is a separate service that can be swapped.
When you need it: It suits businesses that need every part of the stack to change independently.
A shop whose speed and experience are not limiting its sales.
When you need it: A well-built standard theme is then faster to launch and cheaper to run.
Capability Maturity — we walk you up the five levels
Operated at Level 4 · Quantitatively Managed — measured, predictable and owned. We track this rank and raise it over time. See the five levels →
Why this matters
Functional value, value-stream value — and why it can't be ignored.
Discovery, architecture, headless storefront build, integration with the existing store back office, go-live testing and monitoring — delivered as a project, or followed by a managed service.
Speed and a custom experience at the point of sale, without the cost and risk of moving the products, orders and customers the business already runs on.
Headless is worth it only when speed or a custom experience is limiting sales. For most shops under a few thousand products, a well-built standard theme is faster to launch and cheaper to run — we tell you which applies to you.
One data layer · measured & owned
Every service creates data — captured, measured, owned.
Upgrade Ecommerce to Headless doesn’t just run — it generates signal. We land that data in one warehouse and turn it into live KPIs tied to a named owner, so performance is attributable and acted on, never trapped inside a single tool.
Data warehouse

Plotly Retool
Apache Superset Platform-agnostic — we connect what you already use and add a warehouse only where it earns its place.
How we select technology
We choose technology last — for the outcomes it has to earn.
Never tech for its own sake. A tool joins the stack only where it measurably protects value, cuts cost or unlocks speed — fit to a designed system, owned where it counts, and measurable from day one. How we select technology →
Speed
Modern, edge-served stacks are sub-second. Slow surfaces cost conversion and SEO every single day.
Cost
Cut licence, hosting and per-task SaaS fees — pay for capability, not lock-in or idle enterprise tiers.
Security
Flat, edge architecture with almost nothing left to attack — fewer moving parts, smaller surface.
Ownership & no lock-in
Composable and self-hosted where it counts — you own the system, not rent someone else’s.
Measurability
Clean data and KPIs baked in — you cannot improve, automate or apply AI to what you cannot measure.
Fit to process
The right tool for a designed system — selected against process readiness, so it amplifies, not adds friction.
