Billow AI Labs on the record

What they shipped

  • From its YC profile: Billow handles the work of Accounting and FP&A FTEs keeping teams compliant and audit-ready. We work within existing stacks (NetSuite, Coupa, and 80+ other systems) and complex spreadsheets, chasing down information and coordinating approvals across stakeholders. Built by repeat founders; Joan built and exited an accounting/ERP platform (45,000 businesses in 4 years) and Phil built Bloomberg's financial “brain” data infrastructure, and as CTO of a trading platform ($1B in volume). Advisors include CFOs, controllers, auditors from publicly-traded biopharma, and a Big-4 Accounting firm. (source)
  • Its own site describes it as: "Billow builds AI employees for finance and accounting teams. Month-end close, reconciliation, AP, and FP&A commentary — executed end to end, fully auditable, while your team reviews and approves. Backed by Y Combinator." (source)

Who is behind it

  • Joanathan McIntosh, Founder/CEO: Co-founder & CEO of Billow AI Labs. Repeat, exited founder - built an accounting/ERP software (45,000 businesses in 4 years).

  • Philip Moniaga, Founder/CTO: Co-founder & CTO of Billow AI Labs. Phil (YC W22) had built Bloomberg’s finance "brain" data infra and co-founded/CTO of a trading platform ($1B+ in volume) (source)
