Overview
Lead engine for real estate wholesalers, delivering high-quality motivated-seller leads.
02
Approach
Built Twilio OTP verification at signup, Stripe subscriptions for lead packs, and a round-robin distribution engine that spreads new leads across active campaigns. Added an auto-recurring billing trigger so when a user's remaining leads hit 1, Stripe silently tops them up.
03
Outcome
Billing and lead distribution run themselves, less manual ops, steadier recurring revenue.
