The Challenge | Finance

When growth outpaces financial resources

As companies scale or prepare for a significant transaction, finance often lags behind momentum. Forecasts drift from reality, reporting is inconsistent across systems, and leaders may lose confidence in the numbers exactly when management, boards and investors need confidence.

Common patterns we see:

  • Runway and unit economics aren’t trusted (or even defined consistently).
  • Revenue quality (pricing, collections, churn, ARR/NRR) is unclear.
  • Control environment can’t keep pace – close cycles slip, audits get noisy.
  • Management, Board and investor readiness is reactive: KPIs change from meeting to meeting, diligence turns into a fire drill.

Without strategic financial leadership, teams make decisions in the dark, slowing growth, weakening negotiating leverage, and increasing execution risk.
