The San Francisco Bay Area, long the dominant region for startup investment, took a step back in this week’s tally of the largest funding rounds. The biggest investments went to companies based in the Seattle area, Southern California, New York and Austin, Texas, while only two of this week’s top 10 are Silicon Valley startups.
But while the geography may look different this week, investors’ appetite for AI remained a dominant theme. One exception, however, was the week’s largest round, for Group14 Technologies, a developer of advanced silicon battery materials.
