Clio has appointed Pablo Arredondo as senior vice president, judiciary, marking the company’s first dedicated move to extend its technology into the courts.
Arredondo cofounded Casetext in 2013 after working as a patent litigator at Kirkland and Ellis and Quinn Emanuel, building some of the earliest AI-driven tools for legal practice.
At Casetext, he helped develop CARA, described as the first brief analyzer, and later CoCounsel, a product credited with bringing generative AI into everyday legal workflows.
Thomson Reuters acquired Casetext in 2023 for $650 million in cash, after which Arredondo joined that company before leaving at the end of last year to consider his next move.
His official start date at Clio is August 31, and he will be tasked with building a dedicated judiciary product line designed around the distinct needs of courts and judges.
“For nearly two decades, Clio has been building toward an ambitious and expansive vision for the role technology can play across the legal system,” Jack Newton, Clio’s cofounder and CEO, said in a statement.
Newton added: “We transformed how law firms run their businesses, expanded into the substantive work of law, and are now bringing that same focus to the judiciary.”
Arredondo’s interest in the judiciary deepened over recent years, including a project at Cornell’s Legal Information Institute using large language models to annotate the US Code of Conduct for Judges with centuries of thinking on judicial ethics from rabbinic, Islamic and Roman Catholic traditions.
That work left him with a heightened appreciation for the long history of tensions surrounding judging, tensions he believes technology must confront directly rather than ignore.
“The judiciary long precedes AI, long precedes computer science,” he said. “A lot of those tensions are still here, are still just as real. And so how we design things needs to not ignore those or wish those away, but rather embrace them head on.”
The scale of the problem he is setting out to tackle is considerable, with Arredondo estimating that enormous volumes of material are landing on court dockets every single week.
“On Monday, somewhere on the order of three billion tokens are going to hit court dockets,” he said, adding that the central question is what can be done helpfully without causing intended or unintended harm.
He pointed to research suggesting a double-digit increase in pro se filings, driven in part by generative AI lowering the barriers to creating and submitting court documents, as a factor increasing that burden further.
Arredondo was direct about why tools built for lawyers cannot simply be transplanted into a courthouse, arguing that what courts require is a fundamentally different category of technology.
“You hear ‘fiduciary grade’ talked about,” he said. “Well, I think ‘judiciary grade’ is its own system.”
He stressed that the judiciary is not a monolith, with appellate courts, trial courts and magistrate judges each facing different needs, and state courts operating under very different constraints to their federal counterparts.
Part of Clio’s appeal for Arredondo lies in its Clio Docket product, now part of Clio Work, which traces its lineage to Docket Alarm, the docket-data company founded by Michael Sander that came to Clio via Fastcase and vLex.
Clio’s $1 billion acquisition of vLex in 2025 brought authoritative legal content including case law, dockets and court records to a platform the company says is now used by more than 400,000 legal professionals across more than 130 countries.
He was unambiguous that none of this work is aimed at replacing judges. “Short answer is absolutely not,” he said. “I don’t see this fully replacing judges.”
Newton called Arredondo “one of the most important builders in legal AI,” saying: “Courts demand the highest standard, and Pablo understands both the potential of AI and the responsibility that comes with applying it in this environment.”
“Clio has the technology, legal data, scale, and long-term ambition to build this the right way,” Arredondo said in the announcement. “We have a chance to define what responsible AI for the judiciary should look like, and I’m incredibly excited to help shape it.”
