Jupiter Lex is a specialised legal technology firm operating at the forefront of the Environmental, Social, and Governance (ESG) and climate litigation sector.
Their core mission is to leverage cutting-edge artificial intelligence (AI) to empower legal professionals and accelerate the pursuit of climate justice globally. By digitising and streamlining the most complex aspects of ESG lawsuits, Jupiter Lex aims to provide a powerful advantage to law firms tackling increasingly sophisticated legal challenges against corporations and governments.
ESG and climate-related litigation are growing rapidly, characterised by immense data volumes and highly technical evidence. Traditional legal practices struggle to efficiently handle this complexity due to several key factors:
Massive data scale: Identifying viable cases requires scanning and analysing colossal, diverse datasets (corporate reports, scientific literature, regulatory filings, internal communications). This process is slow, costly, and prone to human error.
Fragmented plaintiff connection: Identifying and connecting with plaintiffs, especially on a global scale, remains a logistical bottleneck that severely limits the scope and impact of potential class actions or mass tort cases.
Complex evidence synthesis: Building a winning strategy demands the constant integration of the latest legal precedents, evolving scientific consensus, and cutting-edge research, a task that exceeds the capacity of conventional research methods.
Jupiter Lex directly confronts these challenges with an integrated, AI-powered platform designed to streamline and enhance the entire ESG litigation workflow. The solution is built on three core pillars:
AI-powered case discovery: At the heart of the platform is a sophisticated AI engine that automates the discovery process. It scans and analyses massive, diverse datasets to identify high-quality potential cases that align with a legal firm's specific strategy and practice areas. This transforms a manual, resource-intensive task into an efficient, data-driven process.
Digitised plaintiff connection: The platform provides tools to connect with and manage plaintiffs on a global scale. This digital approach removes geographical barriers and streamlines communication and engagement, making it easier to build and coordinate large-scale class-action lawsuits.
Intelligent evidence building: Jupiter Lex strengthens legal cases by providing access to the latest legal intelligence, winning strategies, and relevant scientific research findings. The platform integrates this information, allowing legal teams to build more compelling, evidence-based arguments for corporate and ecological accountability.
