harness-core

AI agent systems for service businesses, built on Claude.
InfraGrowth AI designs AI agent systems for service businesses and teaches consultants how to build them. Consulting and education, not an agency: the systems we build stay in our clients' hands.

What we build
Agent infrastructure we use ourselves first.
Everything we teach or sell runs in our own business before it runs anywhere else.
InfragrowthOS
The internal operating system that runs our business operations with a fleet of AI agents: inbox, content, sales follow-up and finance.
InternalMulti-agentWhatsApp API Kit
A kit for setting up the official WhatsApp Cloud API with an AI agent, for a business or its clients. It includes a panel that reads your Meta setup, a ready-to-connect agent that replies with Claude or OpenAI, a knowledge base, a cost calculator and checklists. You run it with Claude Code or Codex.

A YouTube channel and a community where we teach AI consultants to build agent systems. Long-form videos build the systems on screen and explain the decisions behind them.

Claude is the core of how we build and how we operate.
01
Agentic coding with Claude Code
We build our tools, including harness-core, InfragrowthOS and the WhatsApp API Kit, with Claude Code as our day-to-day engineering environment.
02
The Claude API inside our agents
Our agents call Claude through the API to read context, decide and act, both in our internal operations and in the WhatsApp agent we ship to customers.
03
Claude Code as the interface for customers
The WhatsApp API Kit is designed to be operated by talking to Claude Code (or Codex): customers ask it to read their Meta setup or adjust their agent, and confirm before anything changes.
04
Teaching others to build with Claude
Our videos and community show consultants how to build agent systems with Claude, using the same setup we run ourselves.
