Question
I'm developing a new service about content analysis all by myself and being alone isn't the best environment in which to develop a business service.
2 people working together are always better because they share feedback, insights and find issues more quickly. From creating the MVP, collecting users data, choosing together towards which direction the development should be eventually focused on.
That's a workflow I'm eager to build but being a solopreneur would give me only a "limited set of elements" to develop my idea (knowledge, time, tools, etc.).
Long story short: how can I fully grow this project when I can't find a co-founder?
Answer
It's hard to vet non technical co-founders. Really hard. Unlike developers they can't always (though sometimes can) show you, "here's what I did." They don't benefit from the same kinda portfolio like a designer/artist or developer.
That said, you could go to meetups in your area (if there are any). Network a bit. You gotta put yourself out there and you can't be afraid to talk about your idea. You might even find someone else with the same idea.
More importantly, figure out what you need a co-founder for. It'll be easier to find one then. You'll know what questions to ask and what to look for. Are they helping you find finding? Find customers? Market the idea?
As far as how you do it alone? Self-education. Both programming and design lend themselves well to self-education. Marketing does as well. Especially these days with the internet and social media. You don't necessarily need an MBA, but if you can pick up just a tiny bit of the skills you need to market and push an idea out there, you're going to run into someone to be your business co-founder a whole lot easier. You'll also better be able to evaluate them.
