Cube Software is a 📝Financial Planning and Analysis (FP&A) software company founded in 2018 by Christina Ross, a three-time CFO. Its platform connects a company's accounting, CRM, HR, payroll, and payments data into a single governed data layer and lets finance teams plan, forecast, budget, and report from inside Excel and Google Sheets rather than a proprietary modeling language.
Cube positions itself against legacy FP&A suites by staying spreadsheet-native: models remain in the spreadsheets finance teams already use, while Cube keeps the underlying data current and traceable. At its 2021 $10M Series A, led by Mayfield with Bonfire Ventures and Operator Collective, the company described its focus as mid-market growth companies, with a handful of unicorns and public companies among its customers (VentureBeat). Its website now describes it as an "agentic finance layer for FP&A," with AI agents for data management, analysis, planning, and business partnering, and lists customers from startups to enterprises across software, retail, healthcare, financial services, manufacturing, nonprofits, and real estate. Its users are FP&A analysts, controllers, and CFOs who manage a company's budget and forecast.
I first filed Cube as a tool for the FP&A people who manage the budget of a Series B company. 📝Weekly Accounting provides this service to its larger clients through 📝Bottoms up Budget Facilitation.
