We founded KinCards, an app that lets users create and share virtual business cards with personalized contact information. To manage complex relationships and data, we chose Neo4j, a robust NoSQL graph database that can handle large volumes of data while returning results in milliseconds. With Neo4j's intuitive platform and startup program support, our team was able to quickly learn and implement the technology, building KinCards from scratch within no time. As a result, KinCards is gaining popularity, handling load efficiently with fast response times, flexibility, scalability, and availability, making it easier for users to eliminate physical business cards.
