Why perpetual licensing
Why we never went subscription.
Own it forever
One purchase. Your license does not expire. No surprise repricing, no service shutoff, no held-hostage data.
No cloud dependency
The software runs entirely on your machine. Your models and assumptions never leave your environment. Audit-ready and procurement-friendly.
Predictable budgeting
A one-time capital expenditure, not an operating expense forever. Budget once, forecast cleanly, no renewal-cycle surprises.
