About The Company

We’re building the AI-native operating system for litigation. Today, legal teams face millions of siloed documents across PDFs, emails, and spreadsheets—making facts hard to connect and knowledge fragile. Our platform turns this chaos into knowledge graphs rooted in structured ontologies, compounding insights with every case. The result: faster strategy, stronger arguments, and a lasting edge in high-stakes litigation.

  • Coordinate and prepare materials for executive meetings and presentations, including client and investor presentations, ensuring clear communication.
  • Collaborate with the engineering team to deliver an outstanding product that satisfies the requirements of discerning financial institutions.
  • Manage and lead special projects with high visibility and impact across the company.
  • Analyze complex data to provide actionable insights and recommendations.

Qualifications

  • Bachelor’s degree from a top university.
  • 3+ years of experience in a fast-paced environment, including in a top law firm, legaltech company, consulting firm, or comparable professional environment.
  • Strong organizational and time management skills.
