Buildt AI is generative AI to write iOS or Android native apps from some simple text requirements written by a customer - no code or technical information or experience required. This is not just a web app or a spreadsheet with a layer of UI. Buildt will automatically ‘write’ real code based on the simple requirements provided by the customer.Wealso interviewed technical executives/managers from companies such as Robinhood, Uber, and Cazoo and they were also extremely positive about using Buildt to build internal MVPs, product prototypes and quickly build their "CRUD" apps. Their existing experience with "no code" apps is that they are extremely limited to web apps only and can't satisfy their requirements accurately. | $500K / Pre-Seed / Nov 01, 2022 | |
