Harvey is a startup that sells AI-powered legal software. The firm was initially planning to raise $600 million in funding at a valuation of at least $2 billion to acquire vLex, a 25-year-old legal research firm majority-owned by private equity firm Oakley Capital. However, the acquisition fell apart, and Harvey is now expected to raise about $100 million in a round led by GV at a valuation of about $1.5 billion.
