FAQ
Why is this 4x the price of a generic CRM?

Generic CRMs are databases. Keystone is an intelligence engine. We don't store contacts; we predict transactions.

How does the AI scoring work?

We analyze cross-platform behavior patterns against historical luxury closing data to identify high-intent signals.

Is my client data secure?

Bank-grade encryption. No data selling. Your book of business is your own.

Do you offer onboarding?

Yes. White-glove migration from your existing stack. We do the heavy lifting.
