Has anyone done a GTM agent platform evaluation?

The GTM agent category is getting more attention but when I look at what's actually in production at teams I respect versus what's in demos, the gap is significant. A lot of what's being called an agent is an LLM making one decision based on one input and calling that orchestration. That's not an agent in any meaningful sense. What's actually production ready from a GTM agent standpoint right now? Specifically looking for things running in real workflows at scale rather than working in controlled demo environments.
