What we do

We build focused Shopify apps for problems merchants usually just live with — losing sales when items go out of stock, or wrestling with the files personalized orders depend on. We're a small, founder-led team, and that shows in the product: native to Shopify, reliable under load, and shaped around how you actually sell.

Why merchants choose K1 Apps

A personal approach to every store

You work directly with the founders, not a support queue. We learn how your store actually runs and tailor the app around it — the kind of attention most app teams simply don't give.

Any customization, usually within a day

Need something specific? Tell us, and we'll build almost any customization your store needs — typically shipped within a day, not "sometime next quarter."

AI at the core, so we move fast

AI runs through everything we build, from design to code, so improvements land in weeks and we adapt the moment your needs change.

Native and no-code

Our widgets inherit your theme and install without touching code, so everything looks like a built-in part of your store.

Built to scale

Enterprise-grade infrastructure keeps your storefront fast and reliable through large catalogs and launch-day traffic.
