Who it's for
Regulated entities

We're a small team building a private compliance platform for the work Bermuda's regulated firms deal with every day, from sanctions screening to document review.

Bermuda's regulated firms run on rules that don't bend. Their software should be built for those rules.

We started HarbourFlow to build it. Every screen and every answer traces back to the list entry, rule, or document behind it. And it all runs privately, inside the firm that uses it.

The team

Who's building it.

Brett Williamson, CPA

Co-Founder

Fifteen-plus years owning audit, risk management, strategic finance, and regulatory reporting in heavily regulated industries — healthcare, real estate development, and financial services — repeatedly the senior finance hire building the controls and frameworks auditors, investors, and regulators rely on.

He built finance from the ground up at Elemy, a national pediatric behavioral-health platform that raised $250M+, and for a $300M+ developer that became an agentic-AI construction platform. Through Genesis Advisory he advises regulated financial-services firms on AI governance.

The discipline is always the same: label the data and make it examinable.

Co-Founder

Zach is HarbourFlow's technical co-founder. His background is financial technology, cloud infrastructure, and applied AI — years of building secure platforms for regulated environments, across digital assets, treasury operations, and compliance.

That work includes a raw Bitcoin signer that ran across multiple jurisdictions, and the security and compliance engineering that comes with moving real money. A signed transaction can't be recalled, so the controls around it had to be right the first time.

He started HarbourFlow after seeing how much of compliance still runs on scattered documents and manual process, at firms that answer to some of the strictest regulators in finance.
