John Kleb

John Kleb is a partner with a focus on Strategic Technologies. He began his career building a six-person CPA firm to handle small business accounting. Being part of a small firm, John gained exposure to issues facing other small businesses that blended his CPA background with his passion in technology.

He joined Sikich in 1995 when his accounting practice of 13 years was acquired to lead a newly formed Small Business Unit. In 2000, John was assigned the role of creating a Microsoft Dynamics NAV (Navision at the time) practice. His energy and visibility within the Microsoft ecosystem helped cement Sikich as a global leader in ERP implementation. John also was instrumental in starting the hugely popular Directions Conference for those in the NAV tech community all over the world.

In 2015, John migrated from ERP software to Business Intelligence applications and formed the Strategic Technologies team within Sikich’s technology division. This has allowed John to engage in the exploration of emerging technologies and their practical applications for the firm’s clients.

In his current role, John is a thought leader in new technologies such as Robotics Process Automation, Cognitive Intelligence, Machine Learning, Analytics and Blockchain.
