ROI Hunter
Since 2014, we’ve been building a SaaS platform for large online retailers. Our solution makes digital advertising easier and more effective by turning product data into actionable insights. Today, we influence every 43rd online purchase worldwide, working with leading brands such as Adidas, M&S, Hugo Boss, Sports Direct, and many more. Since 2026, ROI Hunter has been part of part of Pattern, a US-based global ecommerce accelerator. Together, we are building the most complete ecommerce acceleration platform in the world.
Most of our team is based in Brno, covering engineering, product, finance, BI, and people operations. Our commercial colleagues are spread across the UK, Dubai, Brazil, South Africa, and the Czech Republic. We’re 89 people in total, working in a flat structure where openness matters. Everyone can easily connect, even with Karel, our founder and CEO.
“I like working here because I know that my job has an impact. I have a good space to learn new things and I work with amazing colleagues in a very friendly environment. ”
At ROI Hunter, we look for proactive people who aren’t afraid to roll up their sleeves and bring new ideas to the table. In return, we offer freedom without micromanagement, built on trust and support - whether through mentoring, coaching, learning opportunities, or simply having teammates who are always ready to help. As Hunters, we value an open, supportive, and friendly environment, and we expect every newcomer to help us nurture it.
At the very beginning, it was just a project among a few friends. A decade later, ROI Hunter has a global presence, yet its unique atmosphere continues to thrive throughout the company. One of the greatest benefits is flexibility - impact and delivered outcomes matter more than spending the entire day in the office with minimal results.
ROI Hunter influences every 43rd online purchase in the world.
We listen to everyone in the company, and when something is broken, we fix it. That goes for technical things like the architecture or code style, but also for processes or cultural things.
„At ROI Hunter you can always rely on people around you. You are never alone, colleagues here are friendly and helpful.” Honza, Java Developer
„People matter most. We love to learn, take ownership, and build cool stuff together. We’re serious about what we do, but never too serious about ourselves.”
Real impact comes from combining expertise with a curiosity for the needs of the customer. Add in the drive to discover solutions for those needs and your impact will be noticed.
At ROI Hunter, we don’t sit around waiting to be told what to do. We identify what’s important, we suggest solutions, and we focus on executing those tasks.
We are on a continuous path toward improvement. There are always opportunities to make ROI Hunter, and even e-commerce, better. The more we explore, adapt, and experiment with new tools and technology, the bigger impact we will have.
Our transparency and vulnerability are what allows us to move into uncertain, often demanding situations, and expose ourselves to risk. We believe that this moves us forward.
We are open to receiving feedback, as it helps us grow, and we are open to new ideas from anyone who has them.
