The Founder
Marcell Hlavács is the founder behind the Grand Stores group — a growing portfolio of premium e-commerce brands built for global markets. Based in the Czech Republic, Marcell started with a simple belief: every product category deserves a store that actually cares about quality.
Miroslav Bednář is the driving force and founder of Vortex AI, a specialized agency operating under the Grand Stores umbrella. Focused on high-performance AI chatbots and advanced web automation, Miroslav is redefining how businesses interact with the digital world. Based in the Czech Republic, he launched Vortex AI with a clear mission: to transform static websites into intelligent, 24/7 digital powerhouses. By bridging the gap between cutting-edge AI and seamless automation, Miroslav ensures that every brand he touches doesn't just exist online, but actively grows through smart, automated customer engagement.
