INSIGHT

Recurring Revenue Reduces Risk

Recurring revenue is superior because it smooths cashflow and reduces monthly volatility.
Rob says B2B SaaS is more repeatable and less luck-dependent than many startup models.

INSIGHT

Niche Beats Broad By Making Customers Visible

Vertical targets a specific industry while orthogonal targets a specific role across industries.
Rob argues orthogonal and vertical niches simplify marketing and improve product-market fit.

ADVICE

Bootstrap When Unit Economics Work

You don't need venture capital to start many B2B SaaS businesses because of high gross margins.
Consider bootstrapping unless funding is necessary to accelerate proven unit economics.
