What we discovered

We started with customer and user interviews to learn what people were struggling with in daily document workflows, from lost signatures to broken PDF forms, and used that to scope an MVP focused on the highest-frequency pain.

// 02

Research

Deep-dive into competitor apps, mobile scanning stacks and e-signature standards. Defined the minimum bar for legal defensibility, then designed the UX to exceed it invisibly.

Design & Build

A clean, focused interface that turns a phone camera into a document studio, scan, edit, sign, share. Every screen was pressure-tested with real documents before it shipped.

// Problem
  • ×Signing, scanning and form-filling still lives on paper for most people.
  • ×Existing e-sign tools feel like enterprise software, not a phone app.
  • ×No single flow for scan → edit → sign → share.
// Solution
  • Turn the phone camera into a document studio.
  • Draw, type, or scan a signature and drop it anywhere on a PDF.
  • Merge multiple files into one export.
  • Standards-compliant e-sign with legal defensibility baked in invisibly.
// Deliverables
  • Business analysis & MVP scope
  • Wireframes + high-fidelity UI
  • Native mobile app
  • Signature engine + PDF edit stack
