JB Mason's entrepreneurial journey is a masterclass in preparation and execution. The owner of O'Keeffe and O'Malley (M&A Advisory) shares how his career progression, from the high standards of a high-traffic sandwich shop to the corporate precision of Deloitte Consulting, set the stage for his leap into the startup world.   JB explains why his time at DoorDash was his true "MBA," teaching him how to "roll up your sleeves" and solve problems from first principles, like figuring out why Oklahoma City restaurants wouldn't sign up. This unique combination of structure and hustle prepared him to become a searcher and ultimately acquire his M&A advisory firm.   Hear JB’s insights on the peaks and valleys of buying a business, what the due diligence process really looks like, and why being dialed in on your "why" is the single most important factor for success whether you are buying, selling, or simply looking to grow.
