As answered by people managing JavaScript.com and Meishi.
Meishi's answer:
Meishi was born from the founders' personal frustration with the broken contact management system. As stated in their manifesto: "We have not lost control of our data, in truth we never had it and we voluntarily gave it away."
The problem started with simple business card exchanges, but evolved into:
Contact data scattered across corporate databases, social media, and the dark web
Privacy violations (Facebook-Cambridge Analytica scandal)
Massive data breaches
No control over who has your data or ability to update it
The founders realized: "He who owns the data, commands" should be updated to "Who has control of the data, commands." Their mission is to "overturn the balance of power to increase people's independence" by giving individuals—not Big Tech or governments—control over their contact information. It's described as "a mission, a crusade, a call to arms."
Meishi's answer:
Meishi targets two primary segments:
Privacy-Conscious Users (B2C)
Individuals who value data sovereignty and security
People frustrated with outdated contact information
Those concerned about data breaches (64% of consumers fear them)
Freelancers & SMBs (B2B) - US Freelancers: 70M+ professionals needing current client contacts
US Small-Medium Businesses: 33M companies (1-500 employees) facing GDPR/CPRA compliance challenges
Organizations dealing with 70% obsolete B2B data after one year
The Serviceable Addressable Market (SAM) is 1.73M privacy-conscious users (2% of freelancers, 1% of SMBs).
Meishi's answer:
Meishi is unique because it's the only contacts app that gives users complete data sovereignty through a privacy-by-design architecture. Unlike competitors, it combines:
Automatic peer-to-peer synchronization using end-to-end encryption (Signal Protocol)
Zero data storage or monetization - Meishi never accesses, stores, or sells user data
User-controlled data sharing - you decide who gets access and can revoke it anytime
Real-time auto-updates - when contacts change their information, it updates automatically across all connections
Meishi's answer:
Meishi solves problems that no competitor addresses. With Meishi, you get always-current contacts without manual updates, complete privacy control, and protection from data breaches that have affected billions (Yahoo: 3B, Marriott: 500M, Equifax: 147.9M users).
Meishi's answer:
Based on the pitch deck and manifesto:
Core Architecture:
Peer-to-peer (P2P) synchronization for private data exchange
End-to-end encryption (E2EE) via Signal Protocol
Client-server architecture for public search functionality only
Privacy-by-Design principles - no centralized data storage
Infrastructure:
AWS (servers, database, CDN)
Mobile-native development (iOS + Android)
Target: P2P sync <100ms latency
Privacy Technologies:
Inspired by Web 3.0 decentralization concepts (not blockchain)
Zero-knowledge architecture - even Meishi cannot access user data
GDPR/CPRA compliant by design
Meishi's answer:
Meishi is currently pre-launch (seeking $100K pre-seed funding), so it doesn't have customers yet. However, their roadmap targets:
Beta Phase (Q1): 1000 alpha users
MVP Phase (Q2-Q3): 1.2K MAU, $300 MRR
Seed-Ready (Q4): 2K MAU, $2K MRR ($24K ARR)
Planned B2B Partnerships (Year 2):
Calendly
Notion
HubSpot
CRM tools integration
Target Customer Profile:
Freelancers managing 100+ contacts ($10/month)
Small agencies with 500+ contacts ($50/month)
Privacy-conscious professionals and SMBs needing GDPR compliance
