How to evaluate b2b saas ideas

Use these filters before investing serious development or marketing time.

01

Start with a painful, recurring problem in saas & tech rather than a feature looking for an audience. The strongest concepts have an obvious buyer and a reason that buyer needs a solution now.

02

Validate demand before building by interviewing potential customers, reviewing competing products, and testing a focused landing page. Treat market-size figures as directional context, not a substitute for direct evidence.

03

Choose the smallest version that can deliver one valuable outcome. A narrow first release makes pricing, distribution, and customer feedback easier to test without committing months to an unproven product.
