Lineal Taps DISCO IPO Architect to Supercharge AI Strategy

KANSAS CITY, MO – February 04, 2026 – Lineal Services, a global provider of eDiscovery and digital investigation services, has made a significant move to bolster its technological leadership, appointing Keith Zoellner as its new Chief Information Officer. The strategic hire brings a titan of legal technology into Lineal’s fold, signaling an aggressive push to accelerate its AI-driven platform capabilities and expand its global market share.

Zoellner is a well-known figure in the legal tech industry, celebrated for his role in transforming startups into market powerhouses. His appointment is widely seen as a statement of intent from Lineal as it seeks to dominate the increasingly competitive eDiscovery landscape.

A Strategic AI Power Play

Zoellner’s primary mandate at Lineal is to lead product strategy and engineering, with a clear focus on scaling the company's AI-enabled platform, Amplify™. This move is not just about adding a high-profile executive; it's about acquiring a proven playbook for growth and innovation.

His most notable achievement is his seven-year tenure as EVP of Software at CS DISCO. Joining as the first non-founder executive when the company was generating less than $1 million in revenue, Zoellner was instrumental in building the product, design, and engineering teams from the ground up. Under his technical leadership, DISCO’s revenue skyrocketed to over $135 million, culminating in a successful and highly publicized IPO in 2021. He is credited with pioneering AI-driven review capabilities that have since become standard across the industry.

Before his success at DISCO, Zoellner honed his skills at the forefront of data management innovation. At StoredIQ, which was later acquired by IBM, his team developed one of the industry's first integrated eDiscovery appliances, addressing complex information management and early case assessment challenges long before they became mainstream concerns. He also held leadership roles at Spredfast, which was acquired by Vista Equity.

Lineal’s CEO, Major Baisden, emphasized that this hire is about practical results, not hype. “Keith built one of the most successful legal technology products in the market, and he did it by focusing on what actually works for legal teams,” Baisden stated. “We’re not interested in AI for AI’s sake. We’re focused on delivering measurable workflow improvements and cost visibility for our clients. Keith’s track record of taking products from concept through scale, combined with his specific eDiscovery technology background, makes this the right hire at the right time.”

The Hybrid Advantage: Marrying Services and Software

Zoellner’s appointment also shines a spotlight on Lineal’s unique business model, which he will now be responsible for scaling. Unlike many competitors who are either pure software vendors or traditional service providers, Lineal operates on a hybrid model, deeply integrating its proprietary technology with expert-led managed services.

This approach is embodied by its Amplify™ platform, a suite of AI-powered applications designed to work seamlessly within the Relativity eDiscovery environment. With tools like ChatCraft for reviewing complex chat data, Lineal Images for analyzing visual evidence, and PrivFinder for identifying privileged content, Amplify™ is designed to drive efficiency and accuracy throughout the entire discovery lifecycle. The company claims its layered AI model, which combines filters, modeling, and Generative AI, can reduce review cycles from weeks to days.

This integration of software and service is a core part of the company's value proposition. It allows Lineal to offer what it calls "hybrid managed services programs" that provide not just powerful tools, but also the deep operational expertise required to leverage them effectively.

Zoellner himself is a vocal proponent of this strategy. “Most legal technology companies are either selling software or selling services. Lineal is doing something different by combining both with deep operational expertise,” Zoellner said in the announcement. “That integration is hard to execute, but when done right, it delivers outcomes software alone can’t match. I’m excited to help scale platform capabilities that power Lineal’s service delivery and give clients the workflow efficiency and cost transparency they’re not getting elsewhere.”

Navigating a Competitive eDiscovery Landscape

The eDiscovery market is both lucrative and fiercely contested. Valued at nearly $15 billion in 2023, it is projected to more than double to over $31 billion by 2030, fueled by an explosion in digital data and increasingly stringent regulatory requirements. In this environment, standing still is not an option.

Lineal is positioning itself against established giants and agile newcomers alike. The industry is undergoing a significant transformation, with a clear shift towards cloud-based solutions and a growing reliance on managed service providers to navigate the complexity of modern data challenges. AI is no longer a novelty but a foundational technology for organizing, culling, and analyzing vast datasets.

By bringing in Zoellner, Lineal is not just keeping pace with these trends but aiming to set the agenda. The company is already a Relativity Gold Provider Partner and claims to be the "fastest-growing and largest global provider of RelativityOne," giving it a strong foundation. Zoellner’s experience in scaling a platform to IPO-level success provides Lineal with a strategic advantage as it competes for a larger share of the market. His expertise is expected to enhance the Amplify™ suite, ensuring it remains at the cutting edge and continues to deliver the defensible, cost-effective results that corporate legal departments and law firms demand.

Zoellner's Next Act and the Future of Legal Tech

Beyond his corporate roles, Zoellner has established himself as a thought leader on the practical application of artificial intelligence. As an operational advisor with Austin-based Live Oak Ventures, he guided portfolio companies on AI product strategy and even hosted a podcast dedicated to AI implementation for startups. His leadership philosophy centers on building autonomous, cross-functional teams that can innovate rapidly without sacrificing quality—a methodology he will undoubtedly implement at Lineal.

His career represents a clear trajectory, from developing foundational eDiscovery tools at StoredIQ to commercializing advanced AI at DISCO. His new role at Lineal appears to be the next logical step: leveraging that accumulated experience to perfect a hybrid model that combines the best of software innovation with the nuance of expert human service. For Lineal, which has been steadily growing since its 2009 founding through organic expansion and strategic acquisitions, Zoellner's arrival marks a pivotal moment. It is a clear signal that the company is ready to transition from a fast-growing provider to a definitive market leader, with a vision to redefine how the legal industry manages its most complex data challenges.
