Accounting & CPA Firms

Your client's financial data doesn't belong in a cloud AI tool.
Your staff is using one anyway.

Ark33 deploys enterprise AI inside your firm's own infrastructure. Client financial records, tax workpapers, and audit files stay within your perimeter — consistent with your confidentiality obligations and state CPA ethics rules. Your staff gets the productivity. Your clients get the protection they hired you to provide.

The Ethics Gap

The ethics rules haven't caught up to the tools. That's not your protection.

Your staff is under real productivity pressure. Document review, research, draft preparation, workpaper organization — these are exactly the tasks where AI delivers the most obvious time savings. The tools are right there and they're easy to use.

The problem is that the data going into those tools belongs to your clients. Tax records. Financial statements. Audit workpapers. Engagement correspondence. Most state CPA ethics rules and AICPA guidance don't include a carve-out for "we used a BAA-covered AI vendor." Sending client financial data to a cloud AI API is a disclosure of that information to a third party.

The regulatory guidance will catch up. When it does, the firms that adopted AI informally — without a documented confidentiality-compliant framework — will have the hardest questions to answer.

The Solution

AI that processes client data inside your firm. Nowhere else.

Ark33 deploys enterprise-grade AI within your firm's own infrastructure. Client financial records, tax documents, and audit workpapers are processed entirely within your environment. Nothing goes to an external API. We fine-tune the model for accounting workflows — the language, the document types, the specific tasks your staff actually does. The result is AI that performs better on your work than a general-purpose cloud tool, and does it without the confidentiality exposure.

The Confidentiality Chain

Your obligation runs to the client. Not to your vendor.

YOUR CLIENT Financial records Tax workpapers Audit files ENGAGEMENT LETTER YOUR FIRM CPA ethics rules AICPA obligations State licensing rules BAA COVERS VENDOR LIABILITY NOT YOUR DUTY CLOUD AI API Your client's data processed externally outside your control VS. OBLIGATION SOURCE OBLIGATION HOLDER OBLIGATION BREACH

The engagement letter obligates your firm to protect client data. That obligation doesn't transfer to your AI vendor.

Where the Risk Lives

The work your staff is already doing with AI.

These aren't hypothetical use cases. They're the tasks where AI tools deliver the most obvious time savings — and where informal usage is already spreading through accounting teams.

Each one involves client-confidential information. Each one, done in a cloud AI tool, is a potential confidentiality issue. The Ark33 deployment makes every one of them compliant.

Hard Questions

What managing partners always ask.

We have a Business Associate Agreement with our AI vendor. +
A BAA is a data handling agreement between you and the vendor. It doesn't resolve the underlying question of whether sending client financial data to a third-party AI system is consistent with your firm's confidentiality obligations to that client. The engagement letter between your firm and your client governs that relationship — not your vendor contract.
The AICPA hasn't released definitive guidance on AI yet. +
The absence of definitive guidance doesn't create a safe harbor. The existing confidentiality obligations under AICPA ethics rules and state CPA licensing rules apply to client data regardless of what tool processes it. The firms that will have the clearest positions when guidance arrives are the ones who built a defensible framework before it was required.
Our firm is too small for this. +
The firms most exposed are mid-size — large enough to have significant client data volume and staff using AI informally, not large enough to have a dedicated technology compliance function. If your firm handles 20+ clients' financial records and your staff has access to AI tools, you have the exposure.
