Fiori, a Munich-based AI startup, aims to make personalized soft skills coaching more accessible by offering AI-driven communication and thinking skills training through a public beta platform. The platform provides users with negotiation strategy lessons and practice opportunities with virtual AI opponents, alongside feedback and performance evaluations. To support its agile development needs, Fiori integrates EdgeDB within its tech stack, benefiting from a mix of NoSQL-like flexibility and Postgres-like typing, which aids in managing data schemas and queries without the need for a dedicated backend engineer. EdgeDB's features, such as a declarative data schema, query language, and computed properties, allow Fiori to incorporate business logic directly at the database level, reducing redundancy and error-proneness while simplifying code. The startup has leveraged these capabilities to dynamically compute completion dates for its educational lessons, ensuring consistency and efficiency. As Fiori continues to evolve, it anticipates further enhancements in its application through upcoming EdgeDB features like EdgeDB Auth and performance improvements in version 5.0.
