Rillet raised $100M — without even trying

Rillet is an AI bookkeeping tool for small businesses. The company, founded by Nicolas Kopp, sits in a crowded field of tools like QuickBooks and Xero — but it uses AI to pull transactions, match them, and keep the books clean.

On August 21, Kopp walked into a board meeting and laid out the growth numbers. The reaction was immediate. Iconiq, Sequoia and others piled in. The round hit $100 million in 48 hours. The company crossed the unicorn threshold — valued at over $1 billion — without the usual founder marketing cycle. No launch blog post. No PR blast. Just a spreadsheet and a room full of investors.

The lesson is less about Rillet and more about what happens when growth is visible and boring. Investors are chasing tools that do something useful for working people — the kind a shop owner uses at the end of the month to make sure the numbers add up. When that works, capital moves fast. Rillet isn't the only one. A wave of AI tools for accounting, payroll, and ops are getting the same treatment.

Why this matters for us: the money is flowing into tools that serve small businesses, and the next one might be built by someone from our block — so watch what gets funded, and build what the market actually needs.
