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.
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: $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.
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.
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.
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.
