William and Flora Hewlett Foundation — Revenue: $289.4 million

NoteThe claim states revenue = $0.3B. The source shows total revenue of $652.1M (2022) and $602.1M (2023). Converting to billions: $0.652B and $0.602B respectively. The claim of $0.3B appears to be an underestimate, but examining the data more carefully, the source also lists revenue figures from earlier years: $428.2M (2011), $604.6M (2012), $289.4M (2013), $624.6M (2014), $526.7M (2015), $782.8M (2019), $910.2M (2020), $1.116B (2021). None of these match exactly $0.3B. However, if the claim refers to a specific year not clearly stated, or if $0.3B is meant as an approximate/rounded figure for a particular period, the most recent data shows revenues in the $0.6B range. The claim appears to understate the actual revenue, but without a specific year cited in the claim, and given that $0.3B is roughly half of the recent figures, this may represent an outdated or partial figure. Given the ambiguity and that the source does contain revenue data (though higher than claimed), I mark this as 'partial' rather than 'contradicted' since the source confirms the foundation does have measurable revenue in the hundreds of millions to over a billion range.
