Kevin Weil, the former OpenAI product chief, is raising $150 million for a new AI science startup, according to multiple reports. The venture is focused on collecting scientific data to train or improve AI models. Sources also say Weil is targeting a valuation of at least $750 million as part of the funding effort.

The outlets provide similar descriptions of the company’s early stage and lack of a public-facing product. Inc. and Business Insider both characterize the effort as ongoing fundraising discussions and note that details about the startup’s offerings have not been publicly established. Quartz likewise emphasizes the scale of the sought investment and the valuation target, describing the company’s core mission as building around scientific data collection for AI development.

While the coverage aligns on the fundraising amount, leadership, and valuation goal, the reporting differs mainly in emphasis—some highlight that the startup has no public product, while others focus more on the company’s data-gathering orientation and financing targets.
