Who we are

We deploy the operating system, build your agents and train your entire team.

We run our own company on what we deploy.

How we got here

Built from the inside.

harperOS was born under pressure.

At a global digital assets firm, our founder wore three hats — COO, CMO, and CHRO. Hiring wasn’t an option.

He needed leverage. So he became his own Chief AI Officer.

He learned something early on. The popular models — ChatGPT, Claude, Gemini — are tools. Tools don’t propel a company.

What was missing was the operating system around them: one that connected AI across the business and ran on shared knowledge.

Over 24 months, he studied, tested, and built.

That work became harperOS.

Origin of the name

harper. The keeper of knowledge.

Back in the day, a harper was more than a musician. They were the court’s historians and advisors, the keepers of knowledge.

When a harper played, the room learned what had come before. That’s what inspired us to name our company harper.

It’s the operating system that holds your company’s knowledge, preserves what works, and compounds it across every person and every agent in your organization.

Our principles

Six truths we build on.

The goal is growth.

AI is the means. The end is a company that grows, in revenue or in margin.

Change runs deeper than any tool.

AI is every company’s greatest opportunity and its greatest threat. Running on AI is fundamentally about rewiring your company and how you operate.

Technology is a commodity. Your IP is the asset.

Everything the team teaches it compounds into knowledge you own.

Own the rails.

Every company will run on AI. Own the rails it runs on, or your company runs on someone else’s.

Agents own the output. People own the results.

People are accountable for the expertise, the results and the feedback loop that keeps the agents learning.

Every person levels up.

The system takes the work, piece by piece, and each piece it takes frees the person for something more valuable than what they were doing before.
