In this episode of the REWORK podcast, the founders of 37signals highlight the crucial role of managing business costs as a key competitive edge, rather than just concentrating on external rivals. They argue that by prioritizing internal cost control—such as keeping expenses in check and ensuring healthy profit margins—businesses can enjoy greater flexibility, take their time to explore new ideas, and create a more fulfilling work environment. They share their own strategies, which include managing their product portfolio effectively (categorizing products as cash cows, dogs, or shooting stars), cutting unnecessary costs (like cloud services and office space), and maintaining a streamlined team.
