INDUSTRY REALITY

Why US Financial Teams Are Paralyzed by Legacy Software

Disconnected spreadsheets, manual invoice reconciliations, and slow reporting burn expensive analyst hours.

Issue #1

Founders Waiting Days for Routine Financial Reports

Executive decision-makers waiting 3 to 5 business days for finance teams to export, clean, and format basic runway and cash flow updates.

→ Cost: Delayed strategic decisions and poor cash runway visibility
Issue #2

Manual Transaction Categorization Burning High Payroll

Accountants and bookkeepers spending 20+ hours weekly manually reconciling bank feeds and matching supplier invoices.

→ Cost: High accounting overhead and frequent reconciliation errors
Issue #3

Security Vulnerabilities in Disjointed Spreadsheet Chains

Passing unencrypted financial models and payroll data across email and consumer cloud drives creates severe SOC 2 compliance violations.

→ Cost: Security audit failures and client data exposure risks
