Company profile

researched Aug 2026

Blue Onion (legal name Blue Onion Labs Inc.) is a financial technology company that operates a financial subledger and "financial intelligence" platform for retail and e-commerce businesses. Its core function is automated reconciliation: the platform ingests data from marketplaces, payment processors, banks and accounting/ERP systems, matches transactions, orders and payouts, and classifies and attributes the resulting records to produce a single reconciled source of financial truth.

The product is organized into modules aimed at different buyers. Close targets controllers and accountants, with the stated aim of compressing month-end close into a single day with payouts reconciled automatically. Fabric targets CTOs and technical leads, exposing APIs and "agent context" so AI models, APIs and agents can operate on reconciled financial data. Edge, described on the company site as coming soon, targets CFOs and business leaders with margin decomposition and board-reporting analytics. The company also publishes an ROI calculator that estimates savings from automating revenue accounting work and catching revenue discrepancies.

The company was founded in 2020 by Lyndsey Bunting, Charley McMillan and Manav Malhotra, and is headquartered in New York. In April 2025 it announced a $10 million Series A led by Viola FinTech, with proceeds earmarked for expanding AI features, broadening integrations, supporting additional financial account types, and investing in partnerships, events and customer education.
