Questions & Answers

As answered by people managing Codédex and Meishi.

What's the story behind your product?

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."

How would you describe the primary audience of your product?

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  • People frustrated with outdated contact information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).

What makes your product unique?

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

Why should a person choose your product over its competitors?

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).

Which are the primary technologies used for building your product?

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

Who are some of the biggest customers of your product?

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
