We build web applications for ambitious companies.
Fifteen years of practice on high-volume platforms. The projects others find too complex are where we're most useful.
Zebup is a Montreal software development studio. We build custom web applications, SaaS platforms and integrations for small and mid-sized businesses, startups and established companies, in Quebec and beyond. Every project is designed to last, not to look good in a demo.

A tool that fits the way you work, not the way an off-the-shelf package does. Client portals, back offices, approval workflows, dashboards. Delivered documented, tested and ready to hand over.
Learn more : Custom web applicationsMulti-tenant architecture, subscriptions with tiers and quotas, access management, card and mobile-money payments, public API. Platforms built to be maintained for years.
Learn more : SaaS platforms and billingWe connect the tools you already use: online store, accounting, CRM, ERP. Two-way syncs, error recovery, automatic reconciliation. No more re-keying, no more discrepancies found at month end.
Learn more : Integrations and online commerceYour application works, but every change costs more than the last one. We pull the critical components out one at a time, without stopping production, and add tests where there were none.
Learn more : Modernizing existing systemsNo sales funnel. Three steps, each with a concrete result in your hands.
We sell engagements whose first step we can describe. The rest is cut into batches of a few weeks, each one deliverable and stoppable.
A first conversation, free of charge. We take in your needs clearly and tell you what we think, plainly, even if the answer is no.
A written scope, a fixed price for the first batch, a schedule. Simple, transparent, no surprises in the second email.
Short, regular deliveries, documented and tested code, and a clean handover to your team whenever you want it.
We use AI every day to write code. What we never hand over to it is the decision about what to build, and the verification of what was built.
A craftsperson isn't someone who refuses machines. It's someone who answers for their work: they know their materials, they decide what needs doing, and they check before they deliver.
AI writes fast. That makes review and testing more important, not less. At Zebup, AI is a tool in the hands of someone who can recognize good code and owns the result.
Fifteen years of practice on high-volume commerce, pricing and payment systems, in North America, Europe and Africa. Pricing engines handling more than 100,000 transactions a day. Extracting business engines out of monoliths without interrupting service. Leading development teams.
What we take from it: on a system that carries revenue, a full rewrite is almost always the wrong call. What works is gradual extraction, reversible at every step, validated on real traffic. We choose the technology to fit your problem, not the other way around.
