In this episode, Lucas and Luna explore how bootstrapped software founders can use a profit margin filter to make smarter decisions about which products to build, which customers to chase, and which features to prioritize. They dig into the story of a solo founder who turned down a $200,000 enterprise deal because the margin didn't fit, and how that decision freed them to build a $30,000-per-month product with an 85 percent margin. They discuss why gross margin matters more than revenue for bootstrapped companies, how to calculate contribution margin for a feature, and how to apply a margin filter to pricing, customer support, and hiring. Tune in for a practical framework that can help you avoid the trap of high-revenue, low-margin growth and focus on what actually builds wealth.
