What 7 Arbolus experts think of Pydantic

NPS scores in the provided data are strong, with ratings of 7, 8, and 10. Both influencers and experienced users report high renewal intent and satisfaction, reflecting a robust long-term fit for production use and maintainability. Stickiness is significant, as most users report adoption for over one year, with only one in pilot stage. Key expert feedback highlights the importance of explicit validation, integration into modern Python/AI stacks, and ongoing schema maintainability as primary drivers of satisfaction. Main concerns are manageability of schema/versioning over time, particularly in evolving workflows.Overall Customer Sentiment: Positive
