About

Built by someone who has run the close.

ClosedBySeven was founded in 2024 in Chicago's West Loop. We are a small team of accountants and engineers, backed by a Chicago seed fund and by angel investors who are former CFOs and controllers.

Nora Kellbrook

Co-founder and CEO

Nora started in audit, then spent five years as Controller at a private-equity-backed manufacturer with several legal entities. She ran a twelve-day close across a stack of QuickBooks files and spreadsheets, then led a long, expensive move to NetSuite that the company was not ready for. She started ClosedBySeven convinced there had to be something in between.

Sam Bellcroft

Co-founder and CTO

Sam was an engineering lead at a Chicago fintech company. At ClosedBySeven he built the ledger, the bank connections, and the QuickBooks import.

Why “by seven”

Our name is a promise: books closed by business day seven. Seven of our first eight customers do it today. We work with the eighth every month until it does.
