Employee flight-risk detection: know when someone's about to quit.

Teams catch a likely exit weeks early, leaving time to re-engage the person or line up a successor before a key role opens up.

How we operate

Speed, simplicity, and customer obsession.

Customer Success First

We win when customers win. Performance-based pricing and aligned incentives ensure you get value before we get paid. Simple as that.

Simplicity Wins

Complex problems need simple solutions. 10-minute setup vs competitors' multi-day onboarding. If you need a manual, we've failed.

Data Never Lies

Enterprise-grade accuracy guarantees. Published callback rates. Every claim backed by numbers. If we can't measure it, we don't promise it.

Ship Fast, Learn Faster

Idea to revenue in 8 weeks. MVP in weeks, not months. Real customer feedback beats endless planning. Fast failure beats slow failure.

Why this partnership works

Operator + Strategist

Robby handles technical implementation, growth operations, and customer onboarding. Nadav manages strategic planning, financial operations, and business development. Clear separation of responsibilities with aligned objectives.

Speed as a Weapon

MVPs in 2-4 weeks. Market validation before development begins. Rapid iteration cycles (shipping quickly, gathering customer feedback, and pivoting based on data) have secured first-mover status across multiple categories.

Crisis-Tested

Both founders have navigated business failures and downturns, including COVID-19 and market crashes. Data-driven decisions, direct feedback, and shared risk through equal equity have proven resilient across cycles.

Complementary Expertise

Product development, growth operations, financial management, and business strategy: together the founders cover every critical function with no operational gaps.
