Umso, formerly called Landen, is a no-code website builder designed specifically for startups and small businesses that need to get a professional site live fast without hiring a designer or developer. It pairs a drag-and-drop editor with AI-assisted generation that can produce a tailored landing page or full site in seconds from a prompt, and its templates and prebuilt sections are oriented toward startup use cases like product launches, waitlist and early-access sign-ups, investor and pitch pages, and simple marketing sites. Umso includes the practical features a launching company needs, including contact and signup forms with submission handling, basic analytics, SEO controls, custom domains, and multi-language support, and it keeps the editing experience deliberately simple so a founder can make changes themselves. It is positioned against both heavier professional tools that take longer to learn and generic small-business builders that are not tuned for tech startups. Umso is a small, independently run product. It is sold as a paid subscription, typically billed monthly or annually with a short free trial, that covers publishing a site with a custom domain, removing branding, and the forms, analytics, and multi-language features, with higher tiers for more sites and pages.
