AI data startup Snorkel AI is raising $350 million in a Series E and is valuing itself at $3.5 billion, according to reporting. The new funding is presented as support for the company’s “data-as-a-service” model, which focuses on preparing and managing complex training data for artificial intelligence systems.

Both outlets describe a broader market shift in which demand for AI training data is increasing, particularly for more complex use cases. The coverage frames the funding and valuation change as tied to that surge, rather than a single product launch or market event. Where the sources differ in emphasis, one focuses more directly on the size of the valuation jump and the funding amount, while the other highlights the valuation in the context of rising needs for specialized training data.
