Guindo Information

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