Modus Raises $85M to Rebuild Audit Infrastructure with AI-Native Systems

Audit has always been the quiet backbone of the global economy, yet the machinery behind it still hums like it’s stuck in a prior decade. High stakes, zero margin for error, and workflows that feel older than they should be. Modus stepped into that reality and didn’t bother dressing it up. They walked in with $85M and a clear message about where this all goes next.

Modus, the New York City-based AI-native audit platform, just locked in a combined Seed and Series A round led by Lightspeed Venture Partners, with Comma Capital and Garry Tan stepping in as well. Not bad for a company founded in 2025 that decided the best way to fix audit wasn’t to nibble around the edges, but to wire intelligence directly into the bloodstream of the process.

Credit where it’s due. Arush Jain, CEO, saw what most people politely ignore. Audit isn’t broken because people aren’t smart. It’s broken because smart people are stuck doing work a machine should have retired years ago. So Modus built a system that lets auditors act like auditors again. Judgment over janitorial work. Signal over noise. The kind of shift that sounds obvious until you try to execute it at scale.

And here’s where it gets interesting. Modus isn’t just selling software and calling it transformation. They’re investing in audit-first accounting firms and embedding their AI directly into the operation. That’s not a feature play. That’s infrastructure. It’s the difference between handing someone a better tool and rebuilding the entire workshop while they’re still inside.

Early traction tells its own story. A top 200 accounting firm with over $30M in revenue is already in the mix, with the platform live and a pipeline forming behind it. Quietly, that’s how real change happens in industries built on trust. You don’t announce disruption. You earn it, one workflow at a time.

Lightspeed Venture Partners didn’t just write a check because AI is having a moment. They leaned into a market that’s been historically underfed when it comes to technology, despite sitting at the center of capital markets. That imbalance creates opportunity for anyone willing to respect the complexity instead of bulldozing it.

The takeaway isn’t just that Modus raised capital. It’s how they did it. Clear problem, specific customer, and a model that aligns incentives instead of fighting them. They didn’t try to replace accounting firms. They made them sharper, faster, and harder to compete with. Audit might finally be getting out of its own way. And if that happens, don’t expect a loud announcement. Expect cleaner books, faster cycles, and a whole lot of legacy players wondering when the ground shifted under their feet.
