We design high-converting Shopify stores and custom AI business tools for our clients.
Creation, redesign, migration. Technical SEO, Klaviyo.
Automations, API connection, custom apps.
Three paths
for your Shopify.
We'll put your store on the right orbit: whether it's a launch, a transfer, or a re-orbit.
You're launching a brand. We design a store built to sell from day one: conversion-oriented UX, custom Liquid, clean integrations, technical SEO, and app configuration.
Are you coming from Prestashop, Magento, WooCommerce, or Wix? We migrate without data loss or SEO drops. 301 redirection plan, preservation of internal linking, Search Console revalidation.
Is your online store underperforming? We audit, prioritize, and execute. CRO, Klaviyo, SEO. Measurable results, not just slides.
Four brands launched. Real, measured, tracked figures.
You have a PIM, an ERP, Shopify, maybe a CRM, but they don't communicate? We code the layer that makes them work together.
Add ALT tags to 10,000 images. Rewrite link titles in a batch. Fix redirection chains. Everything you don't do because the task is insurmountable, we entrust to AI.
The market app is too generic, too expensive, or doesn't exist. We'll build it. Dashboard, CRM, back-office, AI agent. Connected to Shopify.
Why Stellar and not another
Shopify agency?
Our manifesto fits in one paragraph. Read it before signing elsewhere.
We are not consultants, not freelancers in pajamas, nor a fifty-person company that subcontracts to Manila; we are entrepreneurs, just like you.
We build Shopify sites, but we also operate our own brands.
We know the cost of half a conversion point or a bug at 6 PM on a Friday because we've experienced them ourselves, on our own P&Ls.
Incoming communications.

Signed, dated testimonials, reproduced in full. Our customers are our best ambassadors.
"We switched from Prestashop to Shopify with Stellar at the end of 2022, the best decision for our business: +50% growth in 2023. Since then, we've launched 5 new sites, each in less than 2 months."
