Start-up founder, experienced executive, coach, and advisor. Passionate about getting people from stuck to thriving.
I am assuming you have validated this with your target audience? That being said, I believe you will need at least 2x that much to build and market the application effectively. Crowd sourcing may be a route, but it will be combined with some boot strapping, personal savings and investment from your network as few investors will put anything in until you have an MVP.
You ca do this for certain and agree with the other answer that you do not have to have the skills to create the product. If you are going to bring on a co-founder for the tech side, legal agreements can be to ensure both of you are protected.
You can also think about outsourcing the technical work to one of many companies who can architect and build out your product, meaning that you maintain ownership.
There is surely more than one way to approach, but do not give up on your concept due to a lack of technical skills.
Happy to discuss more if I can be of help to you.
There are most likely many answers to this question depending on the various situations. Having raised four teenagers, all adult and thriving, I would be happy to discuss further if you desire as without any other context, it is hard to answer the question.
I applaud your ambition to wanting to start something new and build it to make a living. Have started two digital marketing agencies before I can attest to some of the challenges and rewards. There are a few places you can look for education like MarketingProfs and Content Marketing World as well as eMarketer. Additionally, you will learn by doing and also recommend you get a mentor who can help you along the way. Best of luck in your journey and let me know if I can help in any other way.
