Withum Fully Adopts DAS Powered by the Caseware Verity AI Platform to Drive its Future-Ready Audit Practice
Top 25 U.S. accounting firm uses DAS to equip professionals with intelligence, confidence and the tools to grow into trusted advisors from day one
TORONTO – June 3, 2026 – Caseware, the leading AI platform for assurance and financial reporting software, today announced that Withum, one of the most innovative and technology-forward accounting firms in the United States, has built its audit practice on the Dynamic Assurance Solution (DAS). As an early adopter of DAS, the firm is harnessing the platform’s transformative methodology, engagement-aware intelligence and integrated platform to drive efficiency, develop its professionals, and deliver higher quality audits.
Withum has deployed the DAS Suite, including DAS, DAS PCR and DAS EBP, to support the firm’s audit and assurance practice transformation. The firm currently has more than 1,000 active users on the platform and has completed more than 6,000 engagements to date.
DAS operates within the Caseware AI ecosystem, where workflow-native intelligence, methodology and engagement data are unified across the end-to-end audit lifecycle. It delivers a fully integrated solution that connects risk assessment and responses to audit workflows within a single system of record. Powered by a transformative methodology, developed by the AICPA in partnership with audit professionals from leading firms, DAS enables a data- and risk-driven audit approach that eliminates the need for disconnected tools, while enabling greater efficiency, audit quality and client value.
An AI platform built for firms that lead
Across Withum's audit practice, team members recognized the power of DAS immediately — and the results have been measurable from day one. Tasks that once took hours are being streamlined, allowing for gains in both efficiency and effectiveness. Professionals at each level are spending time on what matters most, enabling a higher-value auditor and client experience.
Equally important to Withum is how DAS helps develop its people. By embedding contextual, engagement-aware intelligence directly into the workflow, the platform enables practitioners to build genuine understanding from their earliest engagements, learning not just what to do, but why and how it relates to the professional standards. A first-year auditor can now understand disclosure checklist requirements, trace outputs to supporting evidence, and develop the judgment that makes them a trusted advisor, faster.
“Embracing new technology is part of the Withum way. The team’s response since day one has been overwhelmingly positive. Tasks that used to take hours are being streamlined, and professionals at every level are signing off with real confidence. DAS gives our staff the tools to grow into trusted advisors earlier in their careers.” — Kevin McElgunn, Audit Partner and Team Leader Digital Audit Solutions, Withum
David Marquis, chief executive officer at Caseware said, “Withum has long set the bar for what a technology-forward audit practice looks like. They need a platform that can match their ambition and deliver intelligence embedded directly in the engagement, delivering value from the moment it’s deployed. DAS was built for exactly that standard. We’re thrilled that Withum has chosen to build their agentic future on the Caseware Verity AI Platform and look forward to partnering with them as they continue to lead the profession forward.”
Dedicated training and implementation support Withum’s audit transformation journey
CPA.com partnered closely with Withum throughout the adoption journey, bringing the implementation rigor and training expertise needed to translate the firm's readiness into immediate results.
Kalil Merhib, executive vice president, Growth & Professional Services at CPA.com, commented, "Withum came in knowing exactly what they wanted. Our role was making sure they could get there fast and get there right — building a program that matched their pace and ensured every professional was confident from day one. When a firm is this prepared, the focus shifts from change management to velocity."
Looking ahead, Withum plans to expand its use of Caseware’s Verity AI platform. They participated in the testing of the recently launched Verity Disclosure Checklist Agent which automates the review of financial statements, generating citation-backed suggestions auditors can review, refine, accept or override directly within the DAS audit engagement workflow, saving 2.7 review hours per workflow on average. Additional AI-powered tools, including award-winning Extractly and Validate, will extend its use of embedded intelligence across its end-to-end engagement workflow.
