Guindo Design

Guindo is a digital product design studio founded by Carol Alonso and Sergi Sánchez Mancha. Our background spans all kinds of environments and devices (from early desktop software to today’s web, mobile, and AI-powered platforms) collaborating with startups, corporations, and consulting firms across sectors like banking, pharma, public services, and NGOs. We specialize in digital tools for productivity, where task efficiency and user performance are key. We’re strong partners for teams that need to shape ideas, align product and tech, and grow consistently. From early research and conceptualization to design systems, prototyping, and validation. We adapt to every stage. We’ve also taught interaction design in postgraduate programs at UAB, UPF-IDEC, BAU, and UOC, and co-organized UXSpain, Spain’s leading UX event. We're also behind StepAlong, an AI powered tool to create effective product instructions that improve the customer experience. Clients we've worked with include: CaixaBank, Telefónica, AXA, Repsol, Movistar, UN-Habitat, Barcelona City Council, Liberty Seguros, Endesa, UOC, and many more.
