Open stage: AI in products, development, and business: one perspective — three realities [ukr]
In technology companies, AI is already going beyond the trend and influencing products, engineering, and daily business processes. Along with opportunities come challenges: working with sensitive data, security requirements, and the complexity of integration into existing systems. In such conditions, it is important to understand where AI really creates value and where it just adds noise.
During the discussion, participants share their practical experience: how they implement AI in their products, adapt engineering processes, and restructure operations for new tools. This is a conversation about real pain points, opportunities, and solutions that help teams move forward.
