PlotGTM launches free calculator to show startup costs before you spend

A new free web tool aims to take the guesswork out of startup spending. PlotGTM's go-to-market strategy calculator starts with a revenue goal, then estimates the leads, budget and cash required to hit it. The browser-based tool flips the common approach of picking channels and splitting a budget first, hoping revenue follows. For founders mapping out their next product launch, this gives a concrete cost picture before any real money changes hands.
