Enabling efficiency, collaboration, and transparency

About Xcential Legislative Technologies

We transform the drafting, amending, publishing and codification of legislation, regulations and other critical government documents from antiquated 19th and 20th century technology – pencils, paper, word processors and PDFs – into the machine-processable, cloud-ready and digitally efficient platform required by today’s government counsel and citizens.

Our products enable greater efficiency, collaboration and transparency in the creation of content at the core of government.

Xcential Legislative Technologies has helped solve legislative and regulatory drafting challenges around the world since 2002. That’s when Xcential’s co-founders, Grant Vergottini and Bradlee Chang, began work on modernizing the California Legislature’s drafting system.

Starting in 2004, every legislative proposal moving through the California legislature has been drafted, amended and, if approved, published and codified on systems and software designed by Xcential.

Today – while continuing to support and help the California Legislative Counsel Bureau stay at the forefront of legislative technology, creating ever greater transparency for citizens and better work processes for drafters, representatives and staff – Xcential is bringing its consulting expertise and LegisPro product line to projects at the U.K. and Scottish Parliaments, the U.S. House, the U.S. Government Publishing Office and elsewhere around the world.

We believe in the promulgation of the international XML standard for legislative and regulatory documents, Akoma Ntoso (also known as LegalDocML, and its related U.S. standard, USLM). Vergottini, who drives the company’s technical vision, has been an active participant in the creation of Akoma Ntoso and led our work on the creation of USLM for the U.S. House.

With headquarters in Encinitas, Calif., our team of experts in XML, JavaScript and related development tools is spread around the globe, from Palo Alto to Montreal,

Washington D.C. to Bonn. We have partnerships with the top-level providers of both government workflow tools – Azeus Ltd. – and government and legal information products – LexisNexis AU.
