Helping bars and restaurants work smarter

After over a decade managing one of Seville’s most iconic terrace bars, Antonio Bustamante saw a recurring pain point in hospitality: long wait times and inefficient service. Inspired by the post-lockdown boom in digital payments and QR code usage, he envisioned an app that would let diners order and pay directly from their tables. With no technical team but a strong vision, Antonio turned to Z1 to bring his idea to life—fast, lean, and focused.

Together, Antonio and Z1 co-created Qamarero: a digital ordering and payment solution designed to boost customer satisfaction and operational efficiency. Through structured scoping sessions and a rigorous MVP process, Z1 helped narrow the product to its essentials, combining clean UX, scalable tech, and a fresh brand identity. The result was a product ready for real-world testing within weeks, allowing the founder to focus on sales, talent, and funding from day one.

Since its launch, Qamarero has positioned itself as the digital layer modern hospitality businesses need, offering an outstanding user experience.
