Stephano Slack and Seekr: Building a Trusted AI Workflow for 401(k) Plan Audits
Overview
Stephano Slack is an accounting and advisory firm providing audit, tax, and consulting services. In this video, the firm’s team describes how they worked together with Seekr to bring agentic AI into 401(k) plan audit work, a process that had historically been manual.
Explainable AI agents on SeekrFlow ingest, validate, and structure benefit plan documentation. Auditors get their hours back, and every finding traces to its source.

The challenge
Client data at an accounting firm is sensitive, which shaped how Stephano Slack approached AI. The firm had used ChatGPT Enterprise, but security concerns and the risk of hallucinated output meant it had not built in-house agents. For auditors and CPAs who must attest to their work, every answer has to trace back to a verifiable source document, calculation, or report.
The approach
Stephano Slack and Seekr agreed on a strategic collaboration to deploy secure, explainable AI agents across the firm’s core advisory and audit workflows, starting with 401(k) plan auditing and financial data extraction. Starting with a 12-week phased implementation plan, Seekr engineers worked on-site with the firm’s team to understand the audit process and co-develop the solution, rather than handing over an off-the-shelf product. Within approximately 21 days, the firm’s team had a working tool they could use to accelerate their work.

“Seekr is a strong partner in this effort, bringing secure, explainable AI capabilities that support our teams in delivering accurate, compliant, and scalable assurance and advisory services.” – Mike Stephano, Managing Partner
The outcome
Built on SeekrFlow, the solution lets the team trace outputs to their source documents quickly and repeatedly, giving auditors a basis to rely on the results. The firm sees it as a way to address the talent shortage in accounting: staff spend less time on manual data entry, take on more plan audits, and gain experience across a wider range of plans and issues. It also supports the firm’s advisory work with clients.
“They weren’t just selling us an AI demo… They actually helped us build it.” – Jay Brooks, CPA, Partner.
