In 2019, he published his fourth book, "From the Ground Up: A Journey to Reimagine the Promise of America". The book was widely seen as a candidate memoir as it was published right before the 2020 United States presidential election. His book received 1.9/5 stars on Amazon, after some Democratic voters gave negative reviews, due his possible candidacy splitting the Democratic vote. "Rolling Stone" called the book "stunningly boring" and an "autobiography of a pretentious oligarch." A book promotion stop at Harvard University led to a small student protest. "From the Ground Up" was featured on "The Wall Street Journal"'s bestseller list in February, and was listed as a "New York Times" bestseller for 2019. "Reuters" rated the book highly, yet called it "caffeine free" for its inability to "harness his business success" in a potential White House run.
