How can I validate an app in market that offers a premium service, for which people often use free tools for?

Validation and monetization - two great questions. See some great tips on how to do validation in this answer: https://clarity.fm/questions/6423/how-do-you-do-market-research (happy to help you plan your specific validation process) Regarding monetization - the most suitable business models in this case would be commission / intermediate fee taken from either the advertisers or the owners of the advertising spaces (spas, coworking spaces) or both of them. Good luck I've successfully helped over 350 entrepreneurs, startups and businesses, and I would be happy to help you.

The easiest answer to this is something a mentor told me a few years ago when I was working on a niche app....she said "do you honestly feel like you could be passionate about this for the next 10 years"? That may not sound like it's relevant but it is...honestly that's the only thing that matters when starting a compay (besides the obvious of is this valuable)...That's the first thing to figure out. Then when I answered and said maybe, she said "do you think that this is the biggest thing you could be doing with your time? Why stop at helping a few thousand people, why not pour 10 years of your life into something that can help millions".....so reframe your question, is my product only helping a few people? Is there something else I could be doing that will help more people? If the answers are obvious then you know what you need to do...back to the drawing board.

Create an ideal customer profile. Create some questions that will allow to you survey a potential tester to determine if they fit your profile. Design simple landing page with very clear value proposition that speaks to your ideal customer. Ask for a minimum of information up-front (email), but ask for more info after they commit by submitting the first piece of info. (KISSmetrics does a good job of this on their current website trial signup). Use the their answers to these profiling questions to put the applicants into buckets. Let in the most ideal bucket first, or split them into groups if they're big enough. Try and measure engagement the best you can. Measure qualitative and quantitative data. Schedule calls with your beta testers to find out more, especially with the ones who's user behavior seemed to indicate that they didn't get value from your product. Find out why. Make sure they are indeed your ideal customer. Pick up the phone and get to know your customers inside and out. Meet them in person if possible. Incorporate their feedback quickly and get more feedback. Rinse repeat.

Look on Google Communities for technology focused BETA testing groups... Look on Linkedin Groups for business focused potential testers... Look on Facebook Pages for people who like apps/companies like what you are trying to bring to market... That should get you started.

If you are really thinking about building your product you should first do the alpha and beta. There is a strong community of tech people on Hacker News, ProductHunt and Reddit that will support your idea and even pay in advance if you can show a demo first. Give you an example: Dropbox. Drew (CEO) made this short video https://www.youtube.com/watch?v=7QmCUDHpNzE about how Dropbox was supposed to work. He send it to all the community and it becomes viral. Everyone started to sign up. He had a fremium model at start, but look at it now. So I will encourage you to do two things: Follow this order 1-Go and build your alpha/beta and create a demo that everyone can see and feel excited about 2-Share it with the community 3-If you want to "sell it" in advance you can use selz.com or payloadz.com And rethink you business model and moentization strategy so it adapts to your product and not the other way. :) If this helped let me know!
