OPEN SOURCE DOES NOT WIN BY BEING CHEAPER

In the world of open source software, it's not enough for a project to simply position itself as an open-source alternative to a commercial product. To succeed, open-source companies must have a clear reason for being open source or surpass their competitors. Projects like PostHog, Medplum, and Minio succeed by providing transparency and trust in data handling, while others thrive by allowing community-driven integrations and enhancements, ultimately striving to be better than closed-source alternatives.

HOW LINEAR BUILDS PRODUCT

Unlike many tech companies, Linear doesn't employ product managers or cross-functional teams. Instead, it has a single head of product. Rather than setting metric-based goals, it prioritizes a company-wide north-star objective. In contrast to common practice, it doesn't rely on A/B testing for decision-making. Furthermore, its hiring process includes a paid work trial, and the company operates entirely remotely. Impressively, Linear has maintained profitability for over two years, spent a mere $35,000 on marketing, and experienced minimal employee turnover.
