Category Standard

The project 'Exa' (exa.ai) is a high-utility AI search engine with significant external traction, including a recent $85M Series B funding and ~$700M valuation. However, the submission quality is extremely poor; the description erroneously details the history of 'Exa Corporation' (a CFD company acquired by Dassault in 2017) rather than the current AI entity. Despite the user's hallucinated description and inflated 'everyone' reach claim, the actual project's real-world utility, technical innovation, and market timing are exceptional.
