Neith Systems, INDIA · Software product development company

From Android biometric hardware to payment middleware — different domains, the same product-engineering process underneath.

We build software products for clients, end to end. We also build our own — to showcase capability.

One team, one process, built for clients — across VoIP and AI voice systems, cross-platform apps, health tech and payment platforms. Proven daily inside the products we run ourselves: NeithPTT, AI Receptionist, NeithHealth and mBLEchat.

  • Architecture, MVP and release — not just hours billed against a spec
  • One engineering team across mobile, desktop and backend
  • Products we operate ourselves — proof before we ask you to trust the estimate
  • AI applied where it cuts real operating cost — our own AI Receptionist replaces the cost of round-the-clock phone staffing, not just a chat widget for the pitch deck

Our approach is a deep read of today's constraints — the SDK, the protocol, the hardware — before we write the proposal. It is why the estimate holds.

Where we build

Five markets, one engineering team already shipping in each of them.

Figures from 2026 market research, cited where they inform what we build — not a substitute for your own numbers.

VoIP & unified comms

Global VoIP services market, 2026 · ~13% CAGR. UCaaS alone growing 20–26% CAGR through 2031.

Every SIP trunk and calling app we ship sits inside a market still compounding at double digits.

AI voice agents

AI voice agents: $3.5B (2026) → $35.2B by 2033. 70% of routine inbound calls now handled by AI voice.

Our AI Receptionist rides this curve directly — Gartner expects conversational AI to cut contact-centre labour cost by $80B in 2026 alone.

Custom software

Global software development outsourcing, 2026, growing to $977B by 2031. India's own custom-software market: 28.5% CAGR.

The same product engineering discipline we use on our own apps, applied to yours.

Digital health

Mobile health apps market, 2026 → $145B by 2033. Remote monitoring is 34% of device revenue.

NeithHealth is built for exactly this shift — vitals checks that live on the phone people already carry.

Offline & mesh comms

Store-and-forward messaging over a BLE + Wi-Fi Direct mesh, no internet or carrier network required.

When cell towers and Wi-Fi go down, mBLEchat's mesh is designed to keep messages moving anyway.

Product engineering

What we build products with, and what we build them as.

Software Product Development

Our core discipline, end to end — the same process behind NeithPTT, AI Receptionist, NeithHealth and mBLEchat, applied to your product.

  • Architecture & technical strategy
  • MVP build and iteration
  • Mobile, desktop and backend, one team
Idea → architecture → MVP → release

VoIP & Cross-Platform Calling Apps

SIP-based VoIP for iPhone, Android, Windows and macOS — customized on PJSIP and open-source SIP SDKs, or built once in Flutter as one Dart codebase for native calling on iOS and Android alike.

  • PJSIP integration, open-source SIP SDKs, WebRTC, XMPP
  • SIP trunk, PBX and call-routing setup
  • Post-Quantum ZRTP, SRTP, DTLS-SRTP encryption
  • Native ring UI — CallKit / Android Telecom
See the Flutter build

Face & Fingerprint Access Control

Android kiosk hardware for door lock/unlock — camera-based face recognition paired with fingerprint biometrics, matched on-premises rather than in someone else's cloud.

  • Camera2 face capture and recognition
  • Fingerprint sensor bridged to a local matcher
  • Locked-down kiosk firmware, single-purpose device
On-prem enrollment · no biometric data leaves the site

POS & Payment Systems

Android point-of-sale terminal software and the middleware behind it — merchant onboarding, card and bank-transfer payment rails, webhook-driven settlement, terminal fleet management.

  • Android POS & payment terminal apps
  • Merchant onboarding & KYC portals
  • Payment middleware & webhook processing

Enterprise IT services

The rest of the stack around the product.

Software Development & Integration

Custom applications, secure APIs and system integrations, plus modernizing what you already have.

  • Custom software applications
  • Web & mobile app development
  • Legacy system modernization

Cloud Services

Migration, management and optimization on AWS, Azure or Google Cloud — secure, compliant, cost-efficient.

  • Cloud migration & architecture
  • Backup and disaster recovery
  • Ongoing cost and performance tuning

IT Consulting & Advisory

Practical, business-driven advisory for digital transformation, technology risk and vendor decisions.

Data & Analytics

Business intelligence, big-data pipelines and AI-driven insight, from warehousing through to models in production.

Outsourced IT Support

Dedicated teams, helpdesk and remote support — staff augmentation or a fully managed remote team.

Our products

Built and run by our own team — proof of the engineering we sell.

NeithPTT

Instant push-to-talk over cellular and Wi-Fi for field teams, security and logistics — group channels, SOS location alerts, and voice notes with automatic transcription.
