Harvey raises $550M at $15.5B valuation, nearly doubling in nine months
↗
Legal AI startup Harvey raised $550 million at a $15.5 billion valuation, co-led by Diffusion and Lightspeed Venture Partners, bringing total funding to over $1.55 billion.
The rapid valuation escalation, from $8B in December to $11B in March to $15.5B now, signals intense investor appetite for legal AI, but the capital intensity raises questions about unit economics and sustainability. Harvey's shift toward in-house and open-weight models also charts a path for vertical AI companies to reduce dependency on frontier labs.
