Heap's rebrand story is one of rapid transformation, where they successfully migrated their tech stack to a Jamstack platform within 21 days, while also rebranding and building a full website. The direction came from the top, with a focus on reevaluating Heap's entire tech stack and replatforming using a decoupled content architecture accommodated by metric-driven analytics. This led to a comprehensive approach that allowed them to get everything done at once, avoiding a drawn-out timeline. With their new Jamstack, they've improved site performance, increased productivity, and enabled agility for future changes. The choice of Jamstack was key to their success, as it met all of their requirements, including ease of use, flexibility, and integration with other applications. Heap's experience demonstrates the importance of focusing on what you do best and providing quality solutions that work well together.
