From Spreadsheets to Live FP&A
Taimur Abdaal, CEO of Causal, on the primitives of financial modelling
The wave of FP&A startups says finance was one of the last big business functions still running core workflows in spreadsheets and email. Engineering got modern developer tools, design got Figma, but finance teams still copied actuals out of QuickBooks, sent budget templates to department heads, and stitched plans back together by hand. That gap created room for products like Causal, Pry, and Runway to rebuild planning around integrations, collaboration, and faster modeling.

The old pain was concrete. Finance teams often exported accounting data, updated models manually, emailed blank budget sheets to sales or engineering leaders, then reconciled versions back into one master plan. New FP&A tools automate data imports and let each department edit controlled views without breaking formulas.

The timing was enabled by infrastructure. Better APIs from QuickBooks, Xero, payroll systems, and other back office tools made it much easier after the mid 2010s to pull live data into planning software, instead of rebuilding everything by hand every month.

Different entrants attacked the same lag from different angles. Pry focused on simple startup forecasting on top of QuickBooks and Xero. Runway emphasized browser based collaboration across departments. Causal positioned itself as a more flexible modeling engine, especially for custom revenue forecasting and scenario work.
The next phase is that FP&A stops being a finance only system and becomes the shared place where hiring plans, sales forecasts, product bets, and cash impact connect. The winners will be the tools that turn department spreadsheets into one live model of how the business actually runs.
