Most SaaS companies spend weeks building elaborate forecasting models only to base projections on gut feelings, then act surprised when ARR comes in 15% below target because they forgot about that summer churn spike that happens every year.

Venture capital is heavily concentrated, with a small number of ultra-unicorns receiving the majority of funding, while mid-tier companies struggle.
