How we sell

Four reasons it's a one-off.
Not a monthly bill.

🔐

You own the software

Perpetual licence. No subscription. No annual renewal pressure. After the first 12 months you choose whether to take updates.

🏛️

Your data never leaves your perimeter

Runs entirely on infrastructure you control. We have no operational access to your messages, calls, files or metadata — by design, not by promise.

📊

Budget without surprises

Fixed cost on signature. Predictable annual maintenance fee for security patches, version upgrades and support. No per-seat creep, no usage spikes.

🚪

No vendor lock-in

Source-escrow option available. If we disappear, you keep running it. Your audit trail, retention policies and discovery exports all stay with you.

The tradeoff: you provide the infrastructure and your IT looks after it. We support it; you don't depend on us to keep the lights on.
