Building communications features and integrations in-house can be costly, time-consuming, and require ongoing maintenance, making it challenging to manage updates and security. Pre-built solutions, like those offered by Nylas, present a scalable and cost-effective alternative that allows companies to focus on core product development and customer satisfaction. By outsourcing infrastructure maintenance, businesses can allocate their technical talent to more impactful work, accelerating go-to-market timelines and improving customer experiences. Successful case studies, such as LionDesk, Pipedrive, Dialpad, and Clio, demonstrate the efficiency and security benefits of integrating pre-built APIs, which can save significant development time and resources while ensuring compliance with industry standards.
