What HLK Ventures does
HLK (legal name HughesLeahyKarlovic Advertising) is a St. Louis-headquartered, independently owned creative brand consultancy that was founded in 1977 and has operated continuously under partner ownership for 47 years. The firm is held by seven partners, all of whom remain active in client engagements, and is led by Eric Karlovic (CEO), Joe Leahy and Shelby Georgis (CCOs), Alison Berry (COO), Ben Bocklage (CSO), Emily Kircher (CMO), and Brad Overby (CFO). It serves enterprise clients in complex and regulated industries including agriculture, healthcare and insurance, financial services, hospitality, consumer products, and emerging fintech, with named engagements spanning Channel, Bayer Traits, Envu, Ambetter, Marriott, BOK Financial, Pivot Bio, Masterbrand, and Coinstar.
The agency's offering is organized around three core service pillars: Connected Experiences (brand strategy, creative development, strategic communications, scalable technology, and performance media integrated into a single continuum), Account-Based Marketing (full-funnel ABM strategy, data and intelligence, creative and content, performance media, sales enablement, martech deployment, and measurement), and AI Services. The AI Services pillar covers custom AI agent development, AI search optimization, data integrity and operational readiness, unstructured intelligence, behavioral intelligence and audience analytics, AI-driven audience modeling, visual intelligence systems, strategic brand agents, predictive sentiment modeling, concept realization platforms, adaptive experience engines, intelligent asset management, and AI-enhanced quality assurance, supported by integrations with 6sense, Demandbase, RollWorks, and CRM/analytics systems.
HLK operates on a project-based professional services revenue model, with pricing not publicly disclosed. It goes to market through direct enterprise business development, an in-house sales motion, and industry reputation, targeting complex industries with difficult brand challenges. It maintains two offices (St. Louis headquarters and a Chicago office that opened in approximately early 2024 and scaled from about 10 to 28 employees), serves the U.S. Midwest market, and has won multiple NAMA Best in Show and first-place regional awards for agricultural marketing campaigns.
