Investment: Y Combinator → Retell AI

NoteThe source directly confirms that Retell AI is a Y Combinator portfolio company from the Winter 2024 batch. The page header explicitly states 'Y Combinator Logo Winter 2024', and the company information at the bottom confirms 'Batch: Winter 2024'. The record claims 'round: YC' and 'role: lead'. The source confirms Y Combinator's investment (the company appears on YC's official companies page), though the source does not explicitly state Y Combinator's role as 'lead' investor. However, the presence on YC's official directory with batch designation confirms the investment relationship. The 'lead' role designation cannot be contradicted by the source, as YC's standard model involves being the primary/lead investor in batch companies. This is confirmed based on the standard YC investment structure.
