TL;DR — Chennai agencies optimise for app volume. alterai.apps (HQ: Kotturpuram) ships AI-native mobile + full-stack enterprise software via alterai.os — Expo apps, Vertex agents, Supabase backend, client portal included. Weeks, not months.
alterai.apps — custom enterprise and mobile software, built from scratch in Chennai
Chennai is one of India's largest hubs for software and manufacturing — and the search results prove it. Agencies like Pyramidion Solutions, Appinventiv, and Chetu rank for mobile app development company in Chennai with promises of hundreds of apps delivered, Flutter teams, and offshore rates.
alterai is headquartered in Kotturpuram, Chennai — and we compete on a different axis: AI-native enterprise software shipped by the proprietary alterai.os engine, not just mobile UI shells with a six-month waterfall.
What Chennai buyers actually need in 2026
AI-connected mobile
Apps wired to live business data and in-app agents — not static CRUD screens.
Niche workflows
Manufacturing, education, real estate, mobility — each industry needs its own logic.
Fast, secure delivery
Stage → prod CI, RLS, OTP auth — production discipline from day one.
Real visibility
Self-service client portal — not monthly status emails and black-box agencies.
Traditional Chennai agencies optimise for volume (200+ apps, cross-platform templates). alterai optimises for complexity (10+ production AI-native systems across niche industries).
alterai mobile development stack
iOS + Android from one codebase, OTA updates, app store deploy
Auth, Row Level Security, realtime, storage, Edge Functions
Production inference, tool use, human-in-the-loop guardrails
Marketing site, admin panel, alterai.os client portal
Global CDN, agent API proxy, monitoring, analytics
Mobile is never isolated. Every app we ship connects to the same enterprise-grade backbone — agents, portal, analytics, billing.
How we compare to typical Chennai agencies
| Dimension | Typical Chennai agency | alterai.apps |
|---|---|---|
| Focus | Mobile UI + basic API | Full-stack + AI agents + portal |
| Timeline | 3–6 months common | Weeks for focused scopes |
| Visibility | PM calls + emails | Self-service client portal |
| AI | Bolt-on chatbot | Native agentic features |
| Proof | App count | Complex niche apps (ERP, LMS, mobility) |
