About Opus Core 33
A UK studio that builds and runs websites, apps and portals for businesses that would rather serve customers than chase technology.
Opus Core 33 was started with a simple view: a small business should be able to own a professional website or app, have it looked after properly, and never pay a percentage of every booking to a platform it does not control.
We have built Android apps from scratch and published them on Google Play, including account systems, admin dashboards and content management. We have built web platforms from scratch, among them a matrimonial platform with member profiles and a room-rental and property-management service. We host and manage what we build: secure HTTPS, daily backups, monitoring and updates.
We work quickly and carefully. Most small changes are turned around the same day. Every change is tested and reviewed before release, you see a private preview before anything goes live, and we can roll back safely if something is not right.
Alongside the build we help businesses answer customers faster, with WhatsApp enquiry handling, online forms and notifications, and we produce the branded graphics, promotional images and voice-overs that make an app or site feel finished.
