Finding the right Umbraco partner shouldn't be that hard.
Most teams don't struggle because Umbraco CMS is difficult. They struggle because ownership of their Umbraco website is unclear.
Projects get delivered, but Umbraco support and maintenance fade. Upgrades get postponed. Performance issues pile up. The original developers move on, and no one wants to take responsibility. That's where most generic agencies and short-term contractors fall short.
DotSee is different by design. We are a 100% Umbraco-focused team built for long term support, complex Umbraco upgrades, and projects that require continuity, especially when projects outlive internal teams, vendors, or original assumptions.
We work with digital teams and agencies worldwide as an experienced Umbraco development partner, offering Umbraco expertise, clean ownership, and support that continues after launch.
One Umbraco partner. From implementation to long-term maintenance.
Umbraco Implementation
Over 120 Umbraco websites launched for organisations of all sizes. From straightforward builds to complex, integration-heavy platforms.
We use our internal Themelion framework to standardize common Umbraco functionality, reduce bugs, lower long-term costs, and speed up delivery - while keeping projects fully maintainable and upgrade friendly.
Umbraco thrives with integrations, and so do we. Whether it's CRMs, search, or custom systems, we build with future change in mind.
Upgrades and Updates
Whether we built your site or not, we handle Umbraco upgrades and updates safely, from routine minor releases to full LTS and major version upgrades.
We’re trusted by digital teams and other Umbraco agencies to modernise legacy builds, migrate older versions, and stabilise complex setups without unnecessary rewrites or downtime.
Support & Maintenance
Our Umbraco support and maintenance plans are SLA-backed and designed for long-term stability instead of firefighting.
We provide proactive monitoring, site health reports, and early fixes before issues become critical. No disappearing after launch, no handovers to junior teams.
Support is paired with flexible retainers, so you can continuously improve performance, add features, and evolve your Umbraco site as your business grows.
