About
Paxton is an AI legal research and drafting platform built to give attorneys fast, accurate access to case law, statutes, and regulatory materials without the hallucination risks that have plagued general-purpose AI tools in legal contexts. Founded to address the specific reliability and citation requirements of legal practice, Paxton trained and benchmarked its models against legal accuracy standards that general LLMs consistently fail to meet.\n\nThe platform enables attorneys to research case law, draft motions, summarize contracts, and generate legal memos through a purpose-built AI interface that integrates into standard legal workflows. Unlike general AI assistants, Paxton's outputs include verifiable citations and are optimized for the precise, consequential language legal work demands. It targets solo practitioners, boutique firms, and mid-market law firms looking to compete with larger firms' research resources at a fraction of the cost.\n\nPaxton achieved 94% accuracy on Stanford's hallucination benchmark for legal AI — a critical differentiator in a sector where fabricated citations can result in sanctions or malpractice claims. The company raised $28M including a $22M Series A in January 2025, and its 14x MRR growth demonstrates rapid market adoption. As AI legal tools proliferate, Paxton's benchmark-verified accuracy and purpose-built legal focus position it as a trusted platform in an industry where reliability is non-negotiable.
