I’ve worked at one, but it required a PM who was ruthless about cutting scope and we focused on user stories after establishing a strong feedback pipeline, both technically through CI/CD/tests and with stakeholders. Looking back, that was the best team I’ve ever worked in. We split up to separate corners of the company once the project was delivered (12 month buildout of an alpha that was internally tested and then fleshed out).

Maybe I had greenfield glasses but I came in for the last 3 months and it was still humming.
