Last year was monumental for the AI industry in the U.S. and beyond.
There were 49 startups that raised funding rounds worth $100 million or more in 2024, per our count at TechCrunch; three companies raised more than one “mega-round,” and seven companies raised rounds that were $1 billion in size or larger.
