A name that survives the four tests and a logo that works tiny, both locked before lunch.
Until now your product has had a working name. In the next forty minutes you storm real ones, put each through four brutal tests, and generate a logo that still reads at the size of a fingernail. At noon you lock the name; after that, nobody relitigates it.
A name is the first thing every stranger, judge, and parent meets, and the logo is what they remember. Founders who lock these fast get an afternoon of production; founders who debate them lose the day.
