I run an app development agency UXHYPE and I'm starting a new program where I'll work with different founders in a 1 month sprint to validate or build their products in exchange for a percentage of equity. Depending on where the idea and company is at we'll have 2 options.
Option 1: Validate the product and get first customers
Option 2: Build a working prototype (Only if the product is already validated)
This is very experimental but the goal is to have a validated product ready to pitch investors or a working prototype ready for customers to test and experiment with.
