VICTORIA, British Columbia — Sidian Technologies Corp. ("Sidian"), a Victoria-based data-protection software company, and Caseway AI Inc. ("Caseway") of Vancouver today announced a master partnership to co-develop, co-sell, and distribute an integrated document-automation and data-protection offering for the legal market, beginning in California.

The partnership brings together two complementary products built on Vancouver Island and the Lower Mainland. Sidian's Data Guard is a Microsoft 365-native add-in that detects and removes sensitive content from documents before they are shared or filed, applying true burn-in redaction rather than annotation overlays that can later be reversed. Caseway's CaseForm automates the completion of court forms and case documents, and is already live in the 8am/MyCase marketplace used by U.S. law firms. Integrated, the two create a single fill-and-protect workflow: a firm can generate a court document and confirm that protected personal information has been permanently removed before it leaves the building.

The companies are targeting filer-side compliance with California Rule of Court 1.201, Federal Rule of Civil Procedure 5.2, and California public-sector redaction obligations, requirements that expose firms and public agencies to real liability when personal identifiers, medical record numbers, immigration A-numbers, or minors' initials are inadvertently disclosed. The initial rollout focuses on personal-injury practices running CASEpeer and Docketwise, with a paid pilot already scoped around demand- and settlement-package redaction.

Why It Matters for Victoria and the Island

This is a Victoria-built solution aimed squarely at the largest legal market in the world. Sidian is a British Columbia corporation rooted in the Island's technology community, with founding ties to Victoria's Intlabs. The agreement is a working example of a Vancouver Island company competing on compliance and trust, not price, in a U.S. market that increasingly treats data protection as a procurement requirement rather than a feature.

That positioning matters at a moment when British Columbia is pushing to commercialize its research base and export technology in regulated sectors. Redaction and data governance sit at the intersection of legal services, privacy law, and, increasingly, national security and defence procurement, areas where Island and B.C. firms have historically built strong intellectual property but struggled to scale internationally. A revenue-share partnership that keeps both companies independent and B.C.-owned, while giving each a credible route into the U.S. market, is the kind of capital-efficient model that lets Island technology companies grow without surrendering ownership or relocating south of the border.

Leadership Commentary

"Caseway and Sidian are solving the same problem from two directions: how do you make a regulated workflow fast without making it unsafe? Data Guard was designed to remove sensitive content at the source, inside the tools lawyers already use. Putting it alongside CaseForm gives firms an answer they can actually deploy, and gives us a partner that understands the legal market from the inside. We are proud to be building this from Victoria."

— Ben Reichwein, Sidian Technologies Corp.

"I have spent my career watching organizations underestimate how hard it is to remove sensitive information cleanly, and how expensive it is when they get it wrong. What makes this partnership credible is that the redaction is verifiable, not cosmetic. These are two B.C. companies building exactly the kind of defensible, audit-ready technology that travels well into demanding markets."

— Karl Swannie, Advisor, Sidian Technologies Corp. (CEO, Intlabs)

"Law firms do not have a redaction problem because they are careless. They have it because the tools were never built for the way legal documents actually move. Pairing CaseForm with Data Guard means a firm can fill out a court document and know the sensitive content is gone, permanently, before anyone hits send. That is the standard regulated work should be held to."

— Al Vigier, Chief Executive Officer, Caseway

"Trust is the hardest thing to engineer and the easiest thing to lose. In defence and in law alike, the question is never just whether a system works, but whether you can prove what it did after the fact. This partnership reflects that discipline: human-in-the-loop, audit-ready, and accountable. It is encouraging to see B.C. companies setting that bar for themselves."

— Sean Midwood, Advisor, Caseway

Partnership Structure

The companies have entered into a phased master partnership beginning with co-sell, marketplace distribution, and technical integration, alongside a focused paid pilot in California. Caseway will list Data Guard adjacent to CaseForm in the 8am/MyCase marketplace and fund the integration between the two products. Sidian will maintain Data Guard's production availability, provide API and SDK access, and is targeting SOC 2 Type II posture by September 30, 2026. Each company retains full ownership of its own technology, with revenue shared on jointly sourced customers. Government, institutional, and OEM engagements are reserved as future options, activated only by mutual agreement.

About Sidian

Sidian created Data Guard, software that prevents confidential client information from leaving any firm. It finds sensitive details (client records, personal data, health and financial information) across every document your team touches, and permanently redacts them before anything is sent, shared, or filed. There is no system to integrate and nothing to wire up: you install it, point it at your files wherever they live, and one company policy runs automatically across all of them. So a team member sharing a document cannot accidentally expose data that puts you on the wrong side of CCPA or HIPAA or any other privacy law. Learn more at sidian.io.
