The Founder

Built by the person who needed it most.

HarborOS was not designed from a customer interview. It was built by a VP Finance at a PE-backed software company who needed this system and couldn’t find it.

The Origin

From the board room, not the whiteboard.

Every PE-backed CFO knows the drill. The board pack is due Friday. The CRM says one thing. The spreadsheet says another. The renewal forecast lives in someone’s head. And you spend the week before every board meeting reconciling systems that were never designed to talk to each other.

HarborOS was born from that exact frustration. The contract primitive, the reforecast audit trail, the walk-in run rate concept for services — these are solutions to problems encountered firsthand, in a live PE board environment. Not abstractions. Not guesses. Real answers to real gaps.

The Contextual Lighthouse — the feature that lets a CFO write their operating logic in plain language and have it applied to every contract import — exists because no tool ever asked the finance operator what they actually knew. They all asked for clean data instead.

Design Principles

What we believe.

01
The contract is the primitive
Every revenue record is a contract. Not a deal, not a renewal, not an invoice. One record, every view.
02
No clean data required
Bring whatever you have. PDFs, CSVs, CRM exports. The Lighthouse handles interpretation. You handle exceptions.
03
Finance operators know more than they think
The rules in the CFO’s head — ARR definitions, entity logic, grace periods — are the most valuable data in the company.
04
Every dollar traceable
Versioned, immutable, auditable. Every forecast decision has a trail. Every ARR movement has a source contract.
“I built HarborOS because I was tired of rebuilding the same board pack every quarter from systems that didn’t talk to each other. The contract record of truth should exist somewhere.”

Not a Prototype

Live. Production. Real data.

HarborOS runs on live production data at a PE-backed software company. Real contracts. Real board prep. Real weekly operating rhythm.

Multiple tenants are live. The system handles multi-entity, multi-currency operations across US and EMEA. The architecture was designed for PE portfolio deployment from day one.

Send us five contracts. We’ll build the Lighthouse and hand you a live renewals table.
