We built Hirundin to help design, marketing, product and UX teams and professionals. It's designed for people who need to understand customers and users, and make decisions based on their needs and goals. We've designed a suite of tools which radically improve how you think about what you build, ensuring you only create work with provable value, cut the amount of reporting you do, automatically log your thinking, and show value to stakeholders all the way through your process.
