Greg Crouse is a globally-renowned technical implementation and software development expert advising clients in complex intellectual property and systems implementations across industries, including financial services, energy, healthcare, manufacturing, and the public sector. With more than 40 years of experience, he supports clients in navigating critical technology-related litigation and pre-dispute advisory matters, helping them understand how and why technologies fail or breakdown, assess performance, and identify practical solutions.
A systems implementation practitioner by background, Mr. Crouse brings deep expertise in computer software and hardware, including software development and systems engineering. Leveraging this knowledge, Mr. Crouse regularly leads complex global technology implementations involving both commercial off-the-shelf and custom-developed solutions, with particular experience advising on program remediation and technology-related disputes and pre-litigation matters. Mr. Crouse is actively leading multiple complex systems implementations, bringing valuable, real-time execution insights to each engagement.
As organizations increasingly deploy artificial intelligence technologies and systems across business operations, Mr. Crouse is frequently engaged to assess how these technologies perform in practice, including where implementation, integration, or execution issues impact expected outcomes.
Mr. Crouse has extensive experience leading and evaluating complex systems implementations, with a focus on diagnosing and remediating failed or underperforming programs. He has successfully delivered more than 50 large-scale initiatives ranging from $250,000 to $550 million, many of which involved multi-vendor, global delivery environments, and the integration of custom and commercial software. This experience forms the foundation of his work in services disputes, where he is frequently engaged by global organizations — including governmental entities and public companies — to determine how and why implementations fail, breakdown, or underperform.
Mr. Crouse has been retained on numerous engagements to assess broken or at-risk programs, including seven formal project remediation efforts and 26 system assessments focused on identifying gaps in delivery, architecture, and execution. He has led initiatives to develop implementation methodologies and driven transformation efforts directly tied to system failures, including modernizing paper-based banking operations, redesigning compliance processes, and restructuring back-office operating models. His work centers on assessing execution, identifying root cause, evaluating performance against expectations, and providing clear, data-driven perspectives on complex implementation failures.
Mr. Crouse advises on matters involving outsourced technology delivery models, with particular expertise in evaluating vendor performance, governance structures, and multi-party execution failures. He has led operational and process improvement efforts, including business process outsourcing initiatives, where delivery performance and service outcomes were central issues.
Mr. Crouse has designed and built outsourcing capabilities for organizations across industries, giving him direct insight into how these models are structured — and how they break down. Combined with his experience in large-scale, multi-vendor environments, Mr. Crouse provides a practical perspective on accountability, service delivery failures, and the root causes of breakdowns in outsourced technology engagements.
Through more than 40 years of solving unique business problems with enabling technologies, Mr. Crouse has developed deep insight into how technologies are naturally or unnaturally created — and has filed several patents in this space. From this experience, Mr. Crouse has developed a practical, authoritative understanding of originality and how novel concepts translate into functioning systems — enabling him to opine on high-stakes questions of authorship, derivation, and misuse, particularly in complex software and systems environments.
Mr. Crouse has dedicated experience in technology intellectual property disputes and proactive advisory support across patents, copyrights, trade secrets, and trademarks, primarily in software-related matters. His work includes supporting both plaintiffs and defendants in disputes involving patented software concepts, copyright and trade secret issues, and alleged misuse of proprietary technology. He has also been involved in trade secret matters related to data center operations and financial services software, as well as a trademark dispute concerning software and solution infringement.
