Scalestack vs. Lusha

We believe software should serve people, not the other way around. Scalestack is the governed layer between your database and execution. Trusted, AI-ready context available everywhere. We put our AI agents to work cleaning and enriching your data, and turn the results into governed workflows your teams and agents can trust and run on. Replace disconnected and duplicated processes with one controlled layer across your existing systems. Give every team and agent reliable access, clear oversight, and cost visibility.

Lusha is the B2B data and sales intelligence system used by sales, marketing, recruiting, RevOps, and AI agents to find contacts, enrich records, and track real-world buying signals.

Lusha Search gives you verified contact and company data on demand — direct dials with 90%+ accuracy, business emails verified at 95–98% across regions, firmographics, technographics, and buying signals.
