For Entrepreneurs, created by David Skarok (former Matrix Partners VC), is an exceptional resource for SaaS founders and startup operators. The site offers deeply researched, data-driven content on critical topics like customer acquisition costs, churn metrics, and scaling strategies. What sets it apart is the practical frameworks and actual formulas you can apply immediately—the SaaS metrics posts alone are worth their weight in gold. The content skews toward B2B SaaS and venture-backed companies, so bootstrappers or non-tech founders may find less directly applicable material. While the design feels dated and navigation could be improved, the substance more than compensates. A must-bookmark for anyone serious about building and scaling a subscription business.
