A startup needs to move fast - quick and dirty prototypes in JS / Python turn into MVPs. dynamically typed, low barrier of entry, high velocity. Startups that survive to the point of needing to rewrite for stability and performance, will usually opt for Rust or Go. They often dont need the bloated enterprise-specific baggage that comes with C# / Java - transactional models, IoC, ORMs, complex inheritence models - YAGNI.
