A fast-reading ebook for early SaaS founders who need a topic people will actually pay for. Instead of starting with feature ideas, it shows you how to spot repeated workflow pain: the hidden workarounds, duplicate tools, and weekly manual fixes that reveal where budgets already exist. In under an hour, you will learn how to separate noisy complaints from real buying signals, identify the same pain showing up across interviews, and turn those repeats into a sharper SaaS thesis. Built around a simple Pain Pattern Filter, this guide helps you move from vague curiosity to a clearer build direction before you waste months on the wrong product idea.
