Do less, better
A focused tool that nails one job beats a sprawling suite that does everything halfway.
MASM Studios is an independent product studio. We build focused, dependable tools for the people running modern online stores.
MASM Studios started with a simple frustration: the day-to-day software merchants rely on is often bloated, fragile, or trying to do too much. We wanted to build the opposite — small tools that do one job exceptionally well and stay out of your way.
Restock is exactly that: an inventory app for Shopify that quietly keeps you ahead of stockouts. Upshot followed, turning customer feedback into revenue-ranked roadmaps for SaaS teams. Everything we ship follows the same principles.

A focused tool that nails one job beats a sprawling suite that does everything halfway.
Merchants run their livelihood on these tools. Reliability and data safety aren't features — they're the baseline.
We build in the open and talk directly to the people who use our products. Your feedback shapes the roadmap.
We're always listening for the next focused product to build. Tell us what slows your store down — or just say hello.
