A 3-person finance team just scaled past $2 billion in ARR. Your 30-person accounting department is the inefficiency.

Mercor just proved what happens when you replace Oracle Fusion with AI agents inside a general ledger.

Three people. Two billion in ARR. Continuous close. No month-end panic.

Rillet just hit a $1 billion valuation — two years after launch.

It doubled ARR in the last three months alone.
600 customers.
Third raise in 14 months.
Over $200 million in total funding.

And here's the part that should worry every CFO running SAP or Workday:

Forty percent of Rillet's customers are now outside tech.
Waste recycling. Movie studios. Biotech.
Companies that never cared about "AI-native" — until their accountants started leaving.

The U.S. has 340,000 fewer accountants than five years ago.
Not because AI took their jobs.
Because the profession trains smart people to compare PDFs against spreadsheets for a living.

Legacy ERPs store transactions.
Rillet executes accounting.
The difference is architectural.

When your ERP runs on agents instead of data entry, you don't need a finance department that grows linearly with revenue.

You need three people and a system that never sleeps.

Audit your ERP stack today.
If your month-end close still depends on spreadsheets bolted onto Oracle or SAP, you're not running finance — you're maintaining legacy infrastructure.

The next wave of enterprise disruption isn't in your AI lab.
It's in your general ledger.

SIGNAL: AI-native ERP is replacing legacy accounting infrastructure at scale. When a 3-person team can run finance for a $2B company, every enterprise finance org is a cost center waiting to be restructured.
