The source confirms the Series C funding amount ($450M) and the lead investor (Spark Capital) in May 2023, matching the claim's context. However, the source text does not explicitly state the post-money valuation of $4.1B. While the claim references this as a 'Series C post-money valuation,' the actual announcement does not disclose this figure. To verify the $4.1B valuation would require external sources beyond this announcement text.
