Feature gating is a selective access system in software that enables controlled introduction of features, perfect for A/B testing and gradual rollouts. It allows businesses to create tailored pricing plans catering to different customer segments, encouraging upgrades as their business needs expand. This approach not only focuses on customer satisfaction but also acts as a scalable monetization strategy. Despite the challenges involved in feature gating, solutions like Togai offer dynamic pricing and billing tools to streamline the process.
