Do the work before you commit
Most business ideas die on things nobody checked: a price that never covers costs, a launch budget that runs out three months early, a name someone else already owns, a pitch that loses the room on slide two. These tools answer the questions every founder should settle before spending a dollar — how many sales you need to break even, how much cash your launch actually takes, what to call the thing, and whether your name, colours, and deck are ready to show someone.
Everything runs in your browser. There is no account, no email gate, and no data collection on what you enter — type your numbers, build your deck, download a palette, and keep it. When you are ready to act on it, SoGood builds the business around it.
