About Strongsuit

Strongsuit is a legal technology company that provides an AI-powered platform for litigation tasks. The company, which recently rebranded from Callidus Legal AI, offers tools designed to automate and speed up legal research, document drafting, and discovery analysis. The platform aims to augment the work of attorneys, allowing them to remain in control of strategic decisions while the software handles time-intensive tasks. The CEO of Strongsuit is Justin McCallon.

The service integrates a proprietary database of U.S. case law with AI workflows capable of understanding legal precedents and facts specific to a case. Key features include legal research with automated citation and authority identification, analysis of large document sets for discovery, and the drafting of motions and briefs. A significant capability added during its rebranding is automated case validation, also known as "shepardizing," which verifies that cited cases have not been overturned. This feature addresses a traditionally manual and time-consuming process for lawyers. The company states that its tools can help legal professionals close cases three to five times faster and that customers have reported doubling their weekly output.

In 2025, Strongsuit announced it had raised $10 million in funding to advance product development and market expansion. The company serves a range of clients from solo practitioners to large law firms and enterprise legal departments. That same year, Strongsuit was named "Overall Legal Research Solution of the Year" by LegalTech Breakthrough, recognizing its work in legal technology.
