Core Problem Statement

The Problem We're Solving

Primary Problem: People with dietary restrictions face daily anxiety and safety risks due to inadequate information about food ingredients and restaurant safety practices, leading to:

• 3.4 million emergency room visits annually from food allergic reactions
• Significant time waste (2-4 hours weekly) researching safe food options
• Social isolation from fear of dining out
• $33 billion annual healthcare costs from food allergy complications

Why Existing Solutions Fail:

1. Fragmented Information: Users must check multiple apps, websites, and sources
2. Accuracy Issues: 90% of food allergy data is based on unreliable self-reporting
3. Limited Restaurant Coverage: Most solutions focus only on chain restaurants
4. Poor User Experience: Complex interfaces that don't work under pressure
5. No Community Verification: No way to verify information accuracy

Root Cause Analysis

The fundamental issue is the information asymmetry between food providers (restaurants, manufacturers) and consumers with dietary restrictions, compounded by the life-threatening consequences of incorrect information.

Product Vision & Mission
