Withum & Aiwyn Launch Portal to Reshape Client Engagement

PRINCETON, N.J. – March 30, 2026 – In a significant move to modernize client interactions, top-25 advisory and accounting firm Withum, in partnership with technology innovator Aiwyn, today announced the launch of Aiwyn Experience. The new platform is a unified, custom-branded client portal designed to streamline the entire service lifecycle, from initial engagement to final payment.

The collaboration marks a pivotal moment in the professional services industry's ongoing digital transformation, addressing a long-standing gap between rising client expectations and the fragmented, often cumbersome technology traditionally used by firms.

The Digital Imperative in Professional Services

The launch arrives at a critical juncture for the accounting and advisory sectors. A recent Forrester CX Index revealed that overall customer experience quality has fallen to its lowest point in years, largely driven by disjointed digital interactions. Simultaneously, client expectations have soared, with studies showing that over 70% of consumers now expect digital self-service options from their professional providers. This creates a challenging environment where firms must innovate or risk being left behind.

Industry data underscores this pressure. According to research from Aiwyn, a staggering 76% of accounting firms rate client experience as their top priority. Yet, many still rely on a patchwork of disparate systems for document exchange, communication, e-signatures, and billing. This fragmentation creates friction for clients and imposes a significant administrative burden on firm professionals, diverting their time from high-value advisory work.

The market for solutions is expanding rapidly to meet this demand. Projections show the client portal market is set to grow from approximately $1.76 billion in 2023 to nearly $8 billion by 2032. This explosive growth highlights a clear industry consensus: integrated, secure, and user-friendly client platforms are no longer a luxury but a necessity for survival and growth.

A Unified Vision to Close the Experience Gap

Aiwyn Experience is engineered to directly address these challenges by consolidating the entire client journey into a single, intuitive interface. The platform replaces the chaotic web of email threads, multiple login credentials, and separate third-party tools with one centralized hub.

"Our collaboration with Aiwyn reflects our commitment to meeting clients where they are in an increasingly digital environment," said Mike Yarrow, Partner at Withum, in the official announcement. "We didn't just want to adopt technology; we wanted to shape the future of client engagement across tax, audit and advisory services."

The platform’s architecture is both modular and comprehensive. Core components include:

• Centralized Messaging: A secure alternative to scattered emails for all client-firm communication.
• Request Management: Streamlined intake and tracking of client requests and information.
• Document Organization: A secure, organized repository for sharing and storing sensitive files, eliminating the need for insecure email attachments or separate file-sharing services.
• Integrated E-Signatures: Seamless execution of engagement letters and other critical documents within the portal.
• Deliverables Distribution: A clear and simple way for firms to deliver final reports and work products.
• Integrated Payments: A built-in payment system that simplifies invoicing and collections.

By integrating these functions, the platform aims to eliminate the manual coordination and system-switching that plagues many firms, freeing up teams to focus on substantive client work and strategic advice.

A Strategic Partnership Validating a New Standard

This launch is more than just a product release; it represents a deep strategic partnership that validates the market's direction. Rather than purchasing an off-the-shelf solution, Withum actively collaborated with Aiwyn, involving its firm leadership, client service professionals, and innovation teams in the development process. This hands-on approach ensures the platform is not just technologically advanced but also grounded in the practical realities of a large, multifaceted professional services firm.

For Aiwyn, the partnership with a nationally recognized firm like Withum provides powerful validation in a competitive technology landscape. "Working with Withum validates our vision of a connected client ecosystem in professional services," noted Justin Adams, CEO at Aiwyn. He added that Withum's collaboration was instrumental in shaping a platform that can genuinely differentiate firms.

This model of co-creation between a technology vendor and a major industry player serves as a powerful case study. It demonstrates a move away from the traditional vendor-client relationship toward a more integrated partnership model, where technology is co-developed to solve specific, complex industry problems. This synergy is crucial for building tools that deliver meaningful and measurable improvements to both firm operations and the end-client experience.

Beyond the Portal: The Client-Centric Future

From the client's perspective, the impact of such a unified platform is transformative. The new standard promises an end to the frustration of managing multiple passwords, searching through old emails for a specific document, or wondering about the status of a request. Instead, clients are presented with a single, secure, and professionally branded digital front door to their advisory firm.

This client-centric approach empowers users with greater transparency and control. They can easily upload documents, communicate securely with their service team, sign agreements, and pay invoices—all from one location, accessible via desktop or mobile device. This level of convenience, security, and simplicity is fundamental to building and maintaining client trust in a digital-first world.

Ultimately, the launch of Aiwyn Experience by Withum and Aiwyn is a clear indicator of a broader industry shift. Professional services firms are increasingly recognizing that their technology stack is a core component of their service delivery model and a critical driver of client satisfaction. By simplifying technology and unifying the client journey, firms can not only enhance operational efficiency but also strengthen client relationships, improve scalability, and build a foundation for sustainable growth.
