esfiable.app: AI anti-phishing, end to end.

From idea to Google Play release to hundreds of thousands of analyses, esfiable is the receipts: we ship what we sell.

Problem

Phishing is the most common digital threat consumers face, yet the existing tools are either enterprise-grade (Mimecast, Proofpoint, thousands per seat) or sketchy free scanners that mine user data. There was no consumer-grade, privacy-respecting, multilingual option that simply answered: "is this link / QR / email safe?"

02

Approach

We designed esfiable around three non-negotiable principles: (1) anonymous by default, with no signup, no tracking and no upsell, (2) every verdict explains itself in everyday language, (3) the platform must work everywhere the threat arrives: web, Android, browser extension.

03

Solution

A React Native + Expo mobile app for Android, marketing site in Astro, serverless backend on Supabase + Cloudflare Workers. The analysis pipeline combines deterministic checks (SSL, DNS, WHOIS, reputation feeds) with an AI layer (Claude for content classification, OpenAI for OCR on screenshots) inside a strict EU data boundary. Cost per verdict sits below €0.001.

04

Outcome

esfiable runs as a live service with hundreds of thousands of analyses completed. For clients, it proves we can take a consumer AI product from zero to release (design, mobile, backend, AI, growth) with the same team that joins your roadmap.

"We needed to prove we ship products, not slides. esfiable is the proof."
