David Wilson, CTO at Become Education, uses FusionAuth for OAuth and user management, leveraging its ease of use and scalability to support their "careers education as a service" platform. He chose FusionAuth over competitors due to its affordability, human pre-sales support, and serverless deployment model, which would simplify hosting and scaling costs. Wilson praises FusionAuth's flexibility in supporting various identity protocols and frameworks, making it an ideal solution for startups like his company. Despite some minor issues with syncing data between their system and FusionAuth, the platform has greatly accelerated product release timelines by allowing them to focus on features rather than user management.
