Automating monthly finance workflows
Taimur Abdaal, CEO of Causal, on the primitives of financial modelling
The key point is that Causal had to start where Excel pain was obvious and costly, not where Excel loyalty was strongest. Bankers, consultants, and private equity teams are expert spreadsheet users, so a new tool has to prove itself for years before they will trust it with core models. By contrast, startup finance teams at roughly 100 to 500 employees were losing one or two days each month to manual imports, budget checks, and variance reviews, which made the switch easier to justify.

Causal found that its first wedge was not better formulas alone, but automating monthly finance work. The product connected to systems like QuickBooks, Xero, NetSuite, Salesforce, and data warehouses, mapped those records into model variables, and let teams refresh actuals instead of rebuilding spreadsheets by hand.

This is why the early buyer was a modern FP&A team, not a legacy finance institution. Causal said its typical paid contracts were $18K to $36K per year for about 70 mid market customers, and it specifically targeted Series C companies with around 100 to 500 employees where planning complexity had outgrown spreadsheets but processes were not fully locked in.

The broader market split along adoption style. Tools like Vena, DataRails, and Cube let companies keep Excel and layer on integrations and dashboards, which fits conservative spreadsheet heavy buyers. Causal, Runway, and Equals aimed to replace more of the spreadsheet workflow outright, which worked better with younger companies building finance systems from scratch.
Going forward, the winners in FP&A will keep moving up from startup finance teams into larger companies by first owning the painful monthly workflow, then expanding into planning, dashboards, and cross functional collaboration. The hardest accounts will adopt last, once modern tools look familiar enough to trust and have become an accepted system of record alongside Excel.
