Winston Weinberg and Gabe Pereyra transitioned from junior lawyers at O'Melveny and researchers at DeepMind/Meta in 2022, quickly securing seed funding from the OpenAI Startup Fund after a cold start, followed by multiple rounds led by Sequoia, a16z, Kleiner Perkins, Coatue, GIC, and others, with valuation rising from $3 billion in early 2025 to $11 billion, penetrating over half of the Am Law 100 and expanding into corporate legal and asset management clients.

This round of funding is primarily aimed at strengthening cloud-based agent infrastructure, expanding legal engineers embedded in client teams, and accelerating multi-model and custom agent deployment; the motivation is to upgrade validated workflows from auxiliary tools to core infrastructure for law firms and corporations, while reserving ammunition for international expansion and higher average transaction value modules, creating a positive cycle of "capital → product depth → seat expansion → higher valuation."

Similar paths can be seen in early Salesforce's vertical lock-in in CRM or Palantir's deep cultivation in government and enterprise data workflows; Harvey is currently transitioning from rapid customer acquisition to platform control, while competitors like Legora are still catching up in penetration and data flywheel.

Essentially, this represents a combination of capital concentration and technological substitution: the data and workflow barriers in vertical scenarios accelerate the concentration of funds towards a few players that can prove unit economics and customer lock-in, while AI is reconstructing the human leverage and pricing power of legal services, shifting from "selling time by the hour" to "selling structure by results and efficiency."
