What finance teams tell us

"Every month-end, we manually reconcile SAP data against three Snowflake tables. That alone takes three days — before close can even start."

CFO Listed manufacturing group GL Reconciliation

"We have four different Excel files tracking the same KPI. Every time the CFO asks which one is right, nobody in the room can give a straight answer."

Head of FP&A Internet company Data Consistency

"My analysts spend 60% of their time cleaning and formatting data. Less than 40% on actual analysis. That is not what I hired them for."
