Our Firm

American Rigor, Swiss Precision

One firm. Two jurisdictions. Built from day one to deliver compliance audits that satisfy regulators, enterprise buyers, and investors on both sides of the Atlantic.

Our Story

We started Auditsuisse after watching the same pattern repeat: a fast-growing company closes a funding round, lands an enterprise prospect, and then discovers that the compliance audit standing between them and revenue will take four months and cost six figures — from a firm that treats them like a rounding error. We knew there was a better way.

As a licensed US CPA firm with AICPA peer review, we issue SOC 1 and SOC 2 reports that carry the full weight of the American attestation framework. Our Swiss registration under Auditsuisse Assurance AG gives us on-the-ground presence in one of Europe's most respected regulatory jurisdictions — and access to the Swiss Federal Act on Data Protection (FADP), recognized by the EU as providing adequate protection.

Our team brings Big 4 experience, CISA and CISSP certifications, and deep domain expertise across financial services, healthcare, technology, and SaaS. We've completed over 500 engagements for clients ranging from early-stage startups to Fortune 500 enterprises.

What Drives Us

Our Values

Precision

We test every control. We document every finding. We review every report with the attention that Swiss watchmakers give their movements — because your stakeholders deserve that standard.

Transparency

Fixed-fee engagements. Weekly status updates. Direct access to your engagement partner. We think the audit process should be as clear as the report it produces.

Efficiency

Your engineering team has a product to build. Our job is to get the audit done without becoming the bottleneck — 14 days on average, with minimal disruption to your sprint cycle.

We leverage Big 4 experience to deliver the industry's most respected certifications quickly, with minimal friction, and with unparalleled support. Our team of international experts brings Swiss-level precision to every engagement.
