Mecka AI is nearing a valuation of $500 million in a Sequoia-led deal, the TechCrunch AI report says. The startup is about two years old.

According to a source, the new round is forming several months after Mecka AI announced its Series A round. Details of the deal in the provided materials are not disclosed.

Why this matters: the deal points to investor interest in infrastructure and data for training robots. But confirmation is based on a single independent report and its metadata, not on statements from the company or the full text of the publication.
