We design and build web platforms, e-commerce sites, and custom software for businesses that care about getting it right.
We build digital products that help businesses connect with their customers — and we make sure they work as well as they look.
We work with businesses that take their web presence seriously — from local companies building their first platform to enterprises managing millions in online revenue.
We build websites, e-commerce platforms, and custom software. We handle brand identity, UI design, and the backend engineering that keeps everything running. Our work spans strategy through to deployment — we're involved from the initial plan to the ongoing maintenance.
ONMARS started in 2011 when two freelancers — one focused on design, the other on development — realized they could build better work together than apart. What began as a partnership in Calgary turned into an agency built on a simple idea: design should look great and the code behind it should work just as well.
Fifteen years later, that approach hasn't changed. We've worked with over 35 clients ranging from local businesses to Fortune 500 enterprises, building long-term partnerships where we operate as an extension of their team rather than a vendor they rotate through.
We'd like to hear what you're building. Get in touch and let's talk about your project.
