Open-source migration consulting

Reclaim your software. Own your future.

Open Sovereign helps businesses migrate from proprietary software to open-source alternatives — cutting costs, strengthening privacy, and eliminating vendor lock-in.

Your software shouldn't hold you hostage

Businesses spend thousands every year on software subscriptions they can't leave. Licensing changes, price hikes, forced updates, telemetry you didn't agree to. There's a better way.

Subscription Fatigue

Per-seat licensing costs compound fast. A 50-person company can easily spend $50K+ a year on software that has free, capable alternatives.

Privacy Concerns

Cloud-first proprietary tools route your data through third-party servers. For sensitive industries, that's a risk you shouldn't have to take.

Vendor Lock-in

Proprietary formats and ecosystems make it painful to switch. The longer you wait, the harder it gets to leave.

What We Do

End-to-end migration consulting

We research the open-source ecosystem so you don't have to. From initial audit to full deployment, we guide your transition every step of the way.

Software Audit

We inventory every tool your organization uses, map dependencies, and identify which proprietary products have viable open-source replacements.

Migration Roadmap

We build a phased migration plan that minimizes disruption. No big-bang switchovers — just measured, low-risk transitions your team can handle.

Deployment & Training

We handle installation, configuration, and data migration. Then we train your team so they're productive from day one.

Ongoing Support

Post-migration, we provide support contracts to help with updates, troubleshooting, and scaling as your needs evolve.
