# CosX AI

> CosX AI is a digital transformation company that turns existing enterprise systems into intelligent, autonomous operations — production-grade agentic AI workflows built on top of the software you already run, without replacing what works.

## About CosX
CosX AI (COSX.AI LTD, company number 17251803) was founded in 2024 and operates from Bengaluru, India and London, UK, serving clients worldwide. CosX AI builds production-grade agentic AI systems that transform
existing business workflows into autonomous, intelligent operations — without
replacing the software you already run. The focus is real, measurable dollar
impact: moving from "what could AI do?" to "what pays off," then shipping
production agents and embedding senior engineers long-term so the advantage
compounds over time.

## What we do
### Opportunity Map (2 weeks)
Find where AI pays off. A quantified ROI roadmap ranked by impact and feasibility, plus a 90-day delivery plan.

### First Agent (~40 days)
Ship your first production AI agent. A production-grade AI agent wired into live data, tools, and approval flows.

### The Platform (ongoing)
Unify agents, models, and tools. One composable control plane for agents, models, and tools across the business.

### Embedded Team (ongoing)
Senior AI engineers inside your team. Senior AI engineers operating inside your team — daily operations and knowledge transfer.

## Results
3× faster workflow deployment · 60% reduction in manual operational overhead · 100% built on your existing software stack · −54% dead stock · 300+ sites unified · $1M+ loans deployed.

## Case studies
### The operating system for next-generation EV charging networks
Client: MAJOR CPO AGGREGATOR
A charging network running blind across 300+ disconnected sites - rebuilt into a single intelligence platform that sees every asset, detects every anomaly, and acts before revenue leaks. This is what AI looks like when it runs operations, not dashboards.

### From guesswork to AI-led merchandising
Client: PUBLIC LISTED APPAREL CO.
A publicly listed apparel retailer running on intuition and reactive trend-spotting - rebuilt into a signal-driven operating model that reads demand before it peaks and turns it into thousands of SKU decisions a week. This is what AI looks like when it runs the business, not a report on it.

### From concept to a production-ready fintech platform
Client: MAJOR MICRO LENDING CO.
A seed-stage micro-lender with a vision and no infrastructure - taken to enterprise-grade, blockchain-native credit infrastructure that deploys $1M+ in loans across emerging markets. This is what AI and engineering look like when they build the business, not advise on it.
