Pathway is headquartered in Palo Alto, California with additional offices in Paris, France and Wroclaw, Poland.

In 2015, OptiSigns emerged from a straightforward observation: digital signage was too complex, too expensive, and too technical for the businesses that needed it most. Small retailers, restaurants, and corporate offices struggled with clunky interfaces and proprietary hardware that required IT teams to manage. The founders saw an opportunity to democratize digital signage - to build something that anyone could set up in minutes, not hours, and that could transform any ordinary screen into a powerful communication tool. Today, OptiSigns powers over 30,000 customers across 120 countries with a cloud-based platform that balances sophistication with simplicity. Headquartered in Houston with a growing engineering presence in Vietnam, the company has expanded from transforming TVs and tablets into dynamic displays to offering interactive kiosks, AI-powered audience analytics, and enterprise-grade platform services. What started as a mission to make digital signage accessible has evolved into a broader vision: helping organizations of all sizes communicate more effectively with their audiences, whether that means boosting retail sales, engaging employees in corporate offices, or enhancing experiences in healthcare facilities. The platform now supports 190,000+ active screens globally, proving that when you remove technical barriers, businesses will find creative ways to connect.
