Start-up-box

Start-up-box

To launch a company, I published nine open-source assistants that share the work: strategy, brand, pricing, writing, user experience. A tenth chains them together phase by phase, from framing the idea to launch. At each step I validate before the next one starts: the assistant proposes and puts numbers on it, I decide whether the company moves forward.

Nine assistants, one specialty each

Nine assistants share the work: strategy, brand, pricing, writing, user experience, art direction, interface, philosophy, gamification. A tenth chains them in order, from framing the idea to launch.

A validation before each step

No phase moves on to the next without my approval. The assistant proposes, puts numbers on it, executes; I decide whether the company moves forward. This validation isn't a limit placed on the machine, it carries the tool's value.
