Announcing our $22 Million Series A

In 2026, everything is compliance.

Ever since the Securities and Exchange Act of 1934 kicked off the modern era of US financial regulation, complying with rules set forth by the SEC, FINRA, and other regulators has helped investors trust the financial system. It catalyzed the growth of investment advisors and broker-dealers, trusted by everyday people to place their interests first. Compliance, in other words, allowed finance to become modern.

For decades, financial compliance was a machine that produced trust, which is the underpinning of every transaction and every investment.

But like every machine, compliance has changed in the face of new technology.

Artificial intelligence has given the public an unlimited capacity to generate words and images. Fiction and reality have never been harder to distinguish. The world needs compliance more than ever, because the world needs trust in a way none of our institutions have evolved to provide.

In order to execute its mandate and keep integrity at the heart of the financial system, compliance needs to evolve.

That’s what Hadrius is here to build.

Today, we’re announcing $27 million in combined Seed and Series A funding, with the Series A led by CRV alongside Y Combinator, Pathlight Ventures, and angels including the founders of Altruist and Jump AI. This funding gives us the resources to go deeper into the mission we started with: making compliance effortless for regulated financial firms.

Before Hadrius, my co-founders and I ran our own SEC-registered investment adviser. Being regulated meant running our own compliance program. It was our first taste of not only the stresses of compliance (the dozens of workstreams, the endless clerical work, the persistent fear of an audit) but also our first exposure to the impossibly dated tools that were available to help this work.

All of us are pretty technical, so we started automating our own compliance program. Then we realized the problem was much bigger than us.

Compliance didn’t feel like a system of trust-building. It felt like a lot of manual labor that AI could help us do better than the fragmented software the industry had accepted for decades.

That conviction was what led us to build Hadrius.

Hadrius ingests everything into one place, analyzes it with AI agents, and surfaces potential violations for human judgment.

As we keep hearing from compliance officers, Hadrius is arriving not a moment too soon.

CCOs are now responsible for monitoring communications across email, Slack, Teams, WhatsApp, Signal, and AI tools like ChatGPT and Claude.

New trading venues like Kalshi and Polymarket keep appearing.

The volume of information a compliance team must review has grown beyond human capacity. The status quo of disconnected tools and endless manual review is becoming, increasingly, untenable.

Hadrius replaces those legacy point solutions with a single platform. Six agentic modules cover the core of a compliance program, providing oversight of a firm’s people, trading, marketing, communications, branch locations, and compliance manual implementation.

Hadrius ingests everything into one place, analyzes it with AI agents, and surfaces potential violations for human judgment. Compliance teams work more efficiently and contextually, scaling their oversight to every corner of the firm using compliance AI.

With so much growth ahead of us, the results so far have been amazing. More than 500 firms run their compliance programs on Hadrius today, from one-person RIAs to financial institutions with over 100,000 employees, including BBVA, Altruist, Allworth Financial, World Investment Advisors, and M1 Finance. Two-thirds of our customers use three or more modules. Our customers save up to 20 hours a week on compliance work and see a 99% reduction in false positives.

We think compliance done this way is inevitable.

The work has been done the same way for decades: manual, fragmented, mind-numbing for the people doing it. In five years, the industry is going to look back and cringe at how much manual effort it took to keep firms less compliant than they will be with agentic compliance.

The only question is who builds the better way. So far, we’re excited to be leading the pack.

If you are a compliance officer who wants your time back, or someone who wants to build technology for one of the most important functions in financial services, we would love to talk.

In a world of AI slop, everything is compliance.

Hadrius is excited to be building its future. And we’re just getting started.
