How to find and validate business ideas from 75+ SaaS Marketplaces
The best SaaS ideas are often hiding in plain sight.
Case in point.
You can find many ideas in the third-party marketplaces of existing SaaS products from building a better mouse trap to a third-party app that already exists to creating a new third-party app that addresses a problem that you stumbled into mining platform and third-party app reviews.
Regardless of which approach you take, building on top of a third-party marketplace can be a great step one business, since you already have a built-in potential customer base.
While this strategy brings more platform risk, it also makes customer acquisition simpler (in the early days), since you just have to figure out app store SEO to get your product ranking in front of more of your ideal customers.

Finding founder - idea fit
You’ve heard of product-market fit. However, if you are going to invest a significant time on a SaaS idea, you need to make sure it is something you can get behind. That’s because if it is something you believe in, you’ll be more likely to stick it out when you hit a roadblock, experience a growth stall, or times get tough.
Here are some questions to ask yourself to evaluate your new idea.
Does this idea solve a clear problem?
How big is the target market?
Is there a way to reach your target market? How will you acquire new customers?
Do you enjoy - or can you learn to enjoy - hanging around your target customers?
What's the competition like?
What are the technical requirements for building and maintaining the SaaS product?
Do you have relevant experience in the industry or market?
Do you have a passion for the product and the problem it solves?
Do you have the necessary skills to build and maintain the product?
Does the founder have a strong understanding of the target customer base and their needs?
Does this vision you have for this product excite you?
Do you understand the challenges and risks associated with launching and scaling this product?
Does this product fit the type of business you want to run? Think lifestyle business vs. ambitious bootstrapper vs. a unicorn startup.
How to validate your SaaS business idea
Validating your new SaaS idea early is the smartest first step you can take as a founder. In particular, the longer it takes you to build and ship the product, the more important it is to validate the idea early. This prevents you from spending weeks, months, or years building something that no one wants.
The approach you take to validating your idea can look different.
Sometimes, it is as simple as creating a simple landing page and collecting emails.
Other times, it is doing detailed idea validation interviews.
And for some, it may require taking pre-sales from customers.
