Features and specs

What each product offers, as listed by its team.

Code Effects 5 features

Meishi 6 features

No-code rule builder
Provides a visual, English-like rule editor that allows business users without programming skills to create and modify complex business rules and decision logic.
.NET integration
Designed specifically for .NET environments, allowing seamless embedding into C# and VB.NET applications, which is beneficial for teams already invested in the Microsoft technology stack.
Rule compilation to native code
Rules are compiled directly into .NET assemblies rather than interpreted at runtime, which can result in faster execution performance compared to some interpreted rule engines.
Customizable UI components
Offers embeddable rule editor controls that can be styled and integrated into existing applications, giving developers flexibility in how end-users interact with the rule authoring interface.
Reduces developer dependency
By enabling business analysts to author and update rules directly, it can reduce the need for constant developer involvement when business logic changes, potentially speeding up time-to-market for rule changes.

Possible disadvantages

Limited platform scope
Being tightly coupled to the .NET ecosystem limits its usefulness for organizations using other technology stacks like Java, Python, or Node.js, reducing its overall market flexibility.
Learning curve for setup
While the rule editor is designed for business users, the initial setup, integration, and configuration within a .NET application often requires significant developer expertise and time investment.
Niche market presence
Compared to larger, more established business rules engines and decision automation platforms, Code Effects has a smaller user base and community, which can mean less third-party support, tutorials, and shared resources.
Pricing transparency
Detailed pricing information is not always readily available publicly, which can make it harder for prospective customers to quickly assess cost-effectiveness compared to competitors.
Scalability for complex enterprise needs
For very large-scale, multi-platform, or highly complex enterprise decisioning needs, it may lack some of the advanced features, integrations, and scalability options found in more comprehensive decision management suites.

A digital profile with all your contact information always up to date
Contacts
The list of your contacts whose data is always up to date
Calls
The list of calls made and received. If you receive a call from someone who is not in your contact list but is registered with Meishi, in addition to their phone number, all the information they have made public will appear (e.g., photo, first name, last name, profession, company, city, etc.)
Favorites

Questions & Answers

As answered by people managing Code Effects 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
