RJ Scaringe, founder and CEO of Rivian, says his three startups have collectively raised more than $12.3 billion in total funding, according to TechCrunch and The Next Web. Both outlets describe Scaringe as having raised capital repeatedly through multiple companies, with investors continuing to show interest. The Next Web adds that the fundraising pace is accelerating, framing Scaringe as running several ventures at once and attracting investment for each. It also notes that Scaringe holds a doctorate in mechanical engineering from MIT. The outlets describe Scaringe as leading an electric vehicle manufacturer, an autonomous micromobility company, and an industrial AI robotics startup, with each receiving funding. While the specific terms and timing of individual fundraising rounds are not detailed in the excerpts provided, the two sources converge on the overall total—over $12 billion (more precisely, more than $12.3 billion)—across three startups, and on the point that investors remain interested in additional funding.
