How can you estimate market size and growth of a very niche industry?

Maybe hire a freelance market researcher to find out? ;) Generally, something like this is going to appeal to fortune 500 companies. Smaller companies and entrepreneurs are going to be doing market research themselves. From the question it is difficult to tell if you have come into possession of such a platform, or are thinking about building one. Regardless, to succeed it's crucial that you deeply understand who your target customer is and what pain you are solving for them. Most ideas for a business stem from the entrepreneur's discovery of a solution to a problem for a certain group of people. Since who has the greatest need is unclear to you at the moment, the best thing to do might be to contact people at companies who you think have the greatest need. Find a way to get in touch with someone at the company involved in hiring market researchers, and ask them what challenges they face. You can also talk with a few market researchers themselves to get an idea of where they see the greatest demand of companies looking to hire them. Hope this helps.

The best way to do validation on this idea would be to acquire customers through Facebook ads (rich targeting makes you able to cohort users nicely). Then, you could manually pair people via email or through a simple text messaging exchange facilitated by Twilio. In this scenario, you could prompt them to take the actions you think will be at the core of your app's functionality. Observing their engagement rate and what they do with each other would give you some insight into how viable this is. Happy to talk this through in a call with you. I've helped a lot of clarity members through similar customer development exercises.

Even if your competitor continuously capitalizes on your ideas, by imitating your product features, etc., and even if he grows exponentially faster than you, it shouldn't intimidate you. Similar product, less money, whatever else, doesn't matter. Get awesomely creative with your marketing. Focus on the user experience and forget the competition. That's one thing no competitor can ever take away from you. And, the only thing you've got to mediate risk. I'd love to share more with you over a 15 minute call. I can guide you through getting a better understanding of your customers, and developing an awesome user experience, by moving beyond conventional marketing. Looking forward to it. Adrian

As a tech marketer - I am always looking for the fastest, cheapest yet reliable research in order to create competitive intelligence internal documents, stats for blog posts, etc. Some people live by the "if it isn't on the first page, it doesn't matter" when it comes to leveraging search engines as a research tool. However, often when we are looking for value, we have to realize that anything REALLY worthwhile these days from a content perspective is typically gated behind a web form, or nestled inside a blog post. So, expect to spend a few hours in order to get through all the form gates, and also make sure you're using as specific and direct search terms as possible - then getting more generic if results are not ideal. Some other tips: -Have a few "burner" email addresses setup with gmail or hotmail, etc. - these allow you to get content when filling out forms to get White Papers, Reports, Case Studies, etc. without your primary inbox getting stuffed with marketing emails. -In the form fill process, if available put "student" or "researcher" as typically sales reps pass by these "leads" when the form gets dumped into the CRM queue. -Don't forget specialty search sites and tools like Wolfram Alpha for more "numbers" derived searches. -Also, like your question here - always seek the wisdom of crowds in addition to machine learning algorithms! Hope this is helpful! Search on!

Total Addressable (at least in the US) can be built based on market data sets, both free and for fee. For early child care centers, Market Data Retrieval and NCES (publicly available data set) are two recommended sources. For Serviceable, that depends on a) your own business / operating model and b) the current and projected penetration of comparable competitors in market. For the former, consider things like technology usage and implementation capabilities. For the latter, if you have identified clear competitors, it is unlikely that you will have access to accurate info. So, if you can estimate these numbers and reverse-engineer, that's a good starting point. This would also be a great time to consider how your SAAS product is differentiated and will give you a chance to think through different scenario models for customer "switching" (from an existing competitor product to your own).
