We Launch
Tech-Driven Businesses
Graylok is an operator-led holding company. We don't just invest—we build, scale, and run businesses at the intersection of technology and human expertise.
Operators First. Investors Second.
Graylok builds and operates businesses that combine human expertise with intelligent systems. Our portfolio spans publishing infrastructure, talent platforms, literary representation, and real assets—each company designed to scale through operational excellence and AI-augmented workflows. We're not passive investors. We're in the trenches: setting strategy, deploying capital, and building the systems that turn good businesses into great ones.
How We Build
Every Graylok company runs on three principles—each designed to compound over time.
Capital + Leadership
We deploy patient capital alongside hands-on leadership. No absentee ownership. We're accountable for outcomes.
AI-Augmented Operations
We integrate intelligent automation into every workflow—from customer service to financial modeling—multiplying what small teams can accomplish.
Distribution Infrastructure
We build the channels, relationships, and platforms that turn great products into market leaders.

Publishing, talent, real estate: these are relationship businesses transformed by intelligent systems. We build for decades, not quarters.

Tony DiCostanzo
Founder & CEO
Three-time Inc. 500/5000 founder. Former Forbes contributor. Successful exit. Tony built his first company while finishing his MBA at UC Irvine, navigating a healthcare turnaround before founding BookPal—now the leading bulk book distribution platform in North America. He's operated at Disney, scaled companies through acquisition, and written about building businesses for over a decade. Graylok is the culmination of that experience: a holding company designed by an operator, for operators.
