It's been a while since a startup has impressed me with such a mature approach to product development. No promises or a million features. Just a smooth, fast, and perfectly functioning application. I've been using content management applications for over a decade. Notion is perfect; I always come back to it. I have a dozen similar tools purchased from LTD, but Notion's simplicity and effectiveness always draw me back, even though I've grown completely bored with the UI/UX. Buildin is just a copy of Notion with additional gigabytes of space and aspirations to add practical features (Mind Map, Finder, Gumroad). It makes sense, and it's also created in a very pleasant and refined way. It's all I need - clean, not expensive tool to be effective. I love it and hope that they will continue this adventure for long time
