harperOS launches: the first true AI OS.
harperOS wasn't designed in a lab. It was built under pressure inside a global digital assets firm — the operating system that now makes AI work across an entire organization.
NEW YORK — December 1, 2025 — harperOS today launched as the bespoke operating system for companies that want to fully leverage AI. The company helps mid-market and enterprise teams move past the pilot stage and operationalize AI across every department through a single operating layer that connects knowledge, AI agents, and workflows.
The launch addresses a documented gap. McKinsey reports that 73% of AI initiatives never move past the pilot stage. Only 10% of companies have scaled AI agents in any single function. harperOS sets up its clients with a fully customizable operating system — built on Claude Code as the core infrastructure — that includes a company and departmental workspace connecting to tools, models, and stacks that are constantly learning and updating.
“AI tools are abundant. The system that makes AI work across a whole company is missing from the market. I built harperOS while holding three C-level roles at the same firm. I needed support — not just to do those jobs effectively, but to do them better than three full-time specialists could have. I tried every AI model on the market. Some were better than others, but none of them on their own got me where I needed to go.
“The unlock was establishing an operating system that could house the knowledge a company runs on — not all the data, the right data. The signal from the noise. The expertise, the tasks to be done, the decisions that have already been made. The combination of an operating system where that knowledge can be called on, and the discipline of capturing the right knowledge, is what made AI start working. That became harperOS.”
— Michael Chauliac, Founder and CEO of harperOS
harperOS is the product of 24 months and 3,000+ hours of building inside live operations. At the time of launch, the system has deployed 100+ expert agents across 20+ departments and doubled output per team member from day one of deployment.
The product sits above existing AI tools and organizes them into three connected layers: knowledge, agents, and workflows. It stays tool-agnostic by design — clients pick the underlying models and platforms; harperOS provides the operating layer above them.
“I sat in the CMO's seat for many years. When AI became a topic to explore, we chased after it. It rarely produced significant results, never felt connected to what the rest of the team was doing, and in the end wasn't worth the investment.
“When Michael showed me what he'd built, I recognized immediately what we'd all been missing. It wasn't more data, more tools, or more models. It was the curation of the right knowledge — your expertise, your workflows, your decisions — held in one system that every agent and every person can call on. That's what we mean by knowledge as IP. That's the unlock.”
— Patrick Adams, Co-founder, President, and CMO of harperOS
harperOS was built from the inside. Chauliac built the original system at a global digital assets firm where he simultaneously held the COO, CMO, and CHRO roles. With a team spread across functions and a mandate to do more with less, he built the knowledge architecture that gives AI the context it needs, the specialized agents that handle execution, and the workflows that compound productivity across every department.
harperOS is the operating system for companies that want to fully leverage AI. The company is platform-agnostic, methodology-led, and built inside-out from 24+ months of production use. harperOS is headquartered remotely in the United States and France.
