Neptune, an AI-powered concierge service aiding couples in navigating complex financial decisions like prenuptial agreements, successfully streamlined its operations by transitioning to a serverless backend with Neon and Vercel. Previously reliant on Google Cloud SQL, which required significant infrastructure management, Neptune embraced Neon's serverless architecture to reduce operational complexity and enhance development efficiency. This transition, completed with minimal downtime, allows for isolated, testable database environments through Neon's branching model, akin to Git, facilitating rapid and safe development cycles. Integration with Vercel's preview deployments further enables real-time testing without affecting production environments, allowing Neptune's lean team to focus on product innovation rather than infrastructure maintenance.
