Meishi solves two fundamental problems with contact management: data obsolescence and privacy violations.

Primo commento:

The Problem: 70% of B2B contacts become outdated within a year. When someone changes their email, phone, or job, you're left with stale data. Meanwhile, your contact information lives in centralized databases controlled by Big Tech, vulnerable to breaches and misuse.

How Meishi Works: Create a digital profile with your contact information. When you update it, changes automatically sync to everyone you've authorized. No manual updates needed. If you change companies or get a new email, your contacts get the update instantly.

Privacy-by-Design:

P2P synchronization using Signal Protocol for end-to-end encryption
Private data never stored on centralized servers
Client-server architecture only for public search
Grant and revoke access to your information anytime
Zero data monetization—you own your data 100%

Key Features:

Automatic contact updates across your network
End-to-end encrypted private information
User-controlled access permissions
GDPR/CPRA compliant by design
Cross-platform (iOS + Android coming soon)

Why Now: Privacy software market growing at 35.5% CAGR. GDPR fines reached $7.92B in 2025. Major data breaches (Yahoo: 3B users, Marriott: 500M, Equifax: 147.9M) prove centralized databases are honeypots for attackers.

Mission: Reverse the balance of power in data ownership. Instead of Big Tech controlling billions of contact databases, users should have sovereignty over their own information.

Built by a two-person team with 20+ years combined experience in software architecture and design. We're solving our own pain point: the frustration of outdated contacts and lack of privacy control.
