Category Standard

Nextdoor Holdings is a major publicly traded entity with verifiable mass-market adoption and significant real-world utility in hyperlocal networking. While the platform's reach and traction are undeniable (serving millions of neighborhoods globally), the specific submission provided was low-effort, citing 'space-technology' and vague user metrics. Consequently, while the score reflects the high value and scale of the actual business, it is penalized in Response Quality and Technical Innovation due to the poor inputs provided.
