ALTIUS Rolls Out Firm-Wide Legal AI After Testing 15 Tools

Belgian law firm ALTIUS has chosen Legora as its firm-wide AI platform after piloting over 15 tools, beginning full deployment in January 2026.

ALTIUS, one of Belgium's leading independent law firms, selected Legora, a collaborative AI platform built for legal professionals, to support both its lawyers and non-lawyers across the firm. The decision came after an extensive evaluation process and a structured pilot involving roughly 20 lawyers. The move marks a shift from informal, individual AI use to a single shared environment across the entire firm.

The decision signals how law firms are moving beyond small-scale experimentation toward structured, firm-wide AI adoption, with implications for how legal work is staffed, priced, and delivered.

The Evaluation Process

ALTIUS reviewed more than 15 AI tools before selecting Legora. The evaluation was led by an internal legal tech team made up of lawyers from across the firm who had a voluntary interest in legal technology. The team held regular meetings, ran demos, and tested tools over an extended period.

When Legora entered the shortlist, ALTIUS ran a dedicated pilot with around 20 lawyers. Participation required giving structured feedback, making the pilot a direct input into the firm's final decision. Lawyers tested the platform on live matters during the pilot period.

Bregt Raus, Managing Associate in IP and EU Regulatory Law, described what set Legora apart: "Lawyering is a language game, and large language models are a language tool." He also noted that feedback given during the pilot was quickly incorporated into the product, including work to make Belgian legal sources more accessible within the platform.

Why Legora Won

Three criteria shaped the selection: ease of use, confidentiality and data handling, and the quality of legal output. Alongside these, the firm placed weight on the platform's ability to show its reasoning.

Legora's citation and source-grounding system allowed lawyers to move from an answer directly to the underlying source material and inspect how the platform reached its conclusion. For a firm trained to question outputs, this feature proved significant.

Thijs Herremans, Counsel in Corporate M&A, pointed to clause review as a clear early use case. In transactional work, lawyers face tight deadlines and dense contractual language. Legora allowed them to get a first-pass analysis of complex provisions, identify negotiation positions, and suggest revisions. Jan Clinck, Counsel in ICT and Data Protection, used it to surface relevant regulatory authority decisions from large public databases, narrowing the research field while keeping the reasoning tied to source material.

Firm-Wide Rollout

Since January 1, 2026, ALTIUS has been rolling out Legora across the entire firm, covering both legal and non-legal staff. The firm made a deliberate choice to avoid a situation where a small group adopted AI while others fell behind.

Adoption support includes monthly town halls where staff share one practical example of how they used the platform. Department-level know-how meetings now include Legora, with teams exchanging prompts and lessons learned. The firm also paid attention to integration details: Word and Outlook integrations, single sign-on, and a desktop app icon were all cited as factors that reduce friction and help the tool feel like part of daily work rather than a separate system.

Next steps include building shared prompt libraries and standardised workflows for repeatable legal tasks, as well as expanding internal databases that teams can access together.

What AI Means for Legal Work

ALTIUS is deliberate about how it describes AI to staff. The message is that AI supports legal thinking rather than replacing it. Lawyers remain responsible for framing the problem, evaluating the output, and deciding what advice to give.

Valerie Struye, General Manager at ALTIUS, offered a direct framing of the opportunity: "It's the lawyer's bionic powers." She also acknowledged the larger business question: AI disrupts not just tasks but the assumptions behind legal pricing and service structure. The firm's position is that AI should increase value for clients, whether through better work in the same time, new service formats, or more tiered offerings based on client needs.

The firm also addressed training for junior lawyers. As AI takes on some of the labour-intensive tasks that traditionally shaped early legal careers, ALTIUS expects to place greater emphasis on recruiting for curiosity and critical thinking alongside academic credentials.
