"The companies that win are the ones that align technical capability with commercial execution. Most organizations have one or the other. I've spent 30 years building the bridge between them."
He Didn't Learn Business in a Classroom.
He Built It in the Wild.
In 1985, when most kids were watching cartoons, John was running a bulletin board system called Sesame Street BBS, managing hundreds of users from around the world, understanding protocol stacks and building systems automations before the commercial internet existed. By 14, he was “troubleshooting” network security vulnerabilities that major corporations wouldn't encounter for another decade.
That technical foundation didn't go to waste. When Netscape launched SSL encryption in 1994 and made secure online commerce possible for the first time, John was already there, founding ReferralNet, his first online startup. After that he went on to found Kirker & Associates which evolved into The Stirling Bridge Group where he assembled a team that built digital infrastructure for companies that had no idea what they were buying, but knew they needed something.
Over the next seven years, the company served hundreds of clients and over 100 Fortune 500 companies, many through a partnership with TMP Worldwide where his team hosted PizzaHut.com, RyderTruck.com, Sun.com, among others. John personally built the first versions of most of the core products: JobViper, the precursor to ZipRecruiter, the first closed-loop direct mail attribution system (a decade before marketing automation existed), LoanLink.com (the first online loan application tied to automated underwriting), and MortgageSites.com (the first SaaS platform for mortgage banking). His team later went on to refine and scale many of them. Earlier, a formative period working for Jay Abraham sharpened John's understanding of direct response marketing, leverage, and what actually moves revenue.
In 2001, John's company was acquired. He stayed through 2003, then stepped into startup investing and angel deals during the mid-2000s boom. The 2007 crash wiped most of it out. But instead of retreating, he reoriented. The leverage point had shifted. The highest-impact place to apply decades of cross-domain expertise was not inside one company. It was across many of them, at the moments that mattered most.
