Legal-technology company Harvey has raised $300 million in a Series E financing that values the three-year-old startup at about $5 billion, up from $3 billion four months ago. The round was co-led by Kleiner Perkins and Coatue, with participation from Sequoia, GV, DST Global, Conviction, the OpenAI Startup Fund and others. Harvey sells large-language-model tools that draft and review legal documents and now counts 337 corporate and law-firm customers, including KKR and PwC, across 53 countries. Chief Executive Winston Weinberg said the New York-based company will use the capital to double its workforce and expand into adjacent professional-services markets such as tax and accounting. The deal underscores continuing investor appetite for generative-AI applications. In the 24 hours following Harvey’s announcement, voice-dictation maker Wispr Flow secured a $30 million Series A led by Menlo Ventures, data-infrastructure startup Eventual closed a $20 million Series A after a $7.5 million seed, and knowledge-sharing platform Delphi raised $16 million led by Sequoia.
