Small by design.
Big enough to ship what matters.
A two-person Shopify engineering team that actually enjoys the work — and it shows. We write the Liquid, architect the theme systems, and ship directly to production. No account managers. No ticket queues. Just us, in your Slack, getting it done.

How we work
We do production-grade Shopify engineering — not template installs and plugin stacking. Two senior engineers who know the platform inside out and ship directly to your theme.
Most clients see measurable improvements within the first sprint: faster storefronts, cleaner theme code, and features that actually work with their catalog — not against it.
We embed in your team (Slack/Asana/Linear), handle issues end-to-end, and deploy with preview themes so nothing hits production without approval.
What clients say
The Listo team rebuilt our entire product page architecture in three weeks. Page speed scores went from the 40s to 90+, and the codebase is clean enough that anyone can maintain it. They don't just write code — they think about the system.
We burned through two agencies before finding Listo. They diagnosed our checkout drop-off issue in a day and had a fix deployed by EOW. No fluff, no 30-page audit deck — just results. Best Shopify team we've worked with.
What I love about working with Listo is they're genuinely fun to collaborate with. Fast Slack responses, smart suggestions we didn't ask for, and they actually care about our brand — not just closing tickets.
We needed a complete B2B wholesale setup on Shopify Plus. Listo had it live in under a month — custom pricing tiers, net terms, the works. They move faster than our internal team.
