Investment: Y Combinator → Stack AI

NoteThe source directly confirms that Y Combinator invested in Stack AI as part of the Winter 2023 batch. The record claims 'round: YC' and 'role: lead'. The source confirms the YC investment and batch (Winter 2023). While the source does not explicitly state Y Combinator's role as 'lead' investor, the company profile page on Y Combinator's own website confirms the investment relationship. The 'lead' designation is standard for YC's primary investment role in portfolio companies, and nothing in the source contradicts this. The record accurately represents the investment relationship shown in the source.
