Handshake - "Turn casual promises into binding digital agreements."

Hey Product Hunt! 👋 I’m Favor Kay, creator of Handshake. ### 💡 The Spark (Why I Built This) A few months ago, a close friend and I agreed on a simple side project split over coffee. No lawyers, no fancy corporate contracts—just a verbal agreement between two people who trusted each other. But as weeks went by, memory blurred. Who was covering which expense? What was the agreed deadline? What started as a simple promise turned into awkward check-ins and unnecessary friction. It hit me: **Most agreements in our daily lives aren’t corporate buyouts.** They are casual promises—freelance jobs, splitting equipment, loaning money to a peer, or agreeing on project deliverables. But existing legal software makes you feel like you're signing a 40-page mortgage just to confirm a basic deal. I wanted to bridge that gap: keep the human trust of a handshake, but add the clarity of a modern digital signature. --- ### 🛑 The Problem I Wanted to Solve Every day, millions of agreements fall apart—not because of bad intentions, but because of **miscommunication and lost track of commitments**. * PDF templates are clunky on mobile devices. * Traditional e-signature apps are expensive and built for corporate legal teams. * Text messages and WhatsApp promises get buried and forgotten. --- ### 🔄 How My Approach Evolved When I first opened Replit to build **Handshake**, I thought I was just building a simple "signature canvas" on a web page. But as I tested it with real users, my perspective shifted: 1. **Mobile-First Realization:** People don't make casual deals sitting at desktop computers; they do it on their phones. I realized Handshake *had* to feel like a native mobile app (PWA & Android APK), allowing both parties to review and co-sign in under 60 seconds on the spot. 2. **Frictionless Onboarding:** I initially over-engineered mandatory account setups. Users told me: *"Let us draft the agreement FIRST."* I stripped away the friction so anyone can outline terms immediately and send a confirmation link to Party B. 3. **The "Casual Legal" Balance:** I learned that people wanted clear boundaries without legal intimidation. So I shifted the focus from scary legal jargon to transparent, mutual digital confirmation. --- ### 🚀 Where We Are Today Handshake is officially live at **handshakeapp.uk**!
