I worked on an idea for 4 months, found out it already exists
For context, if I were to finish building out my prototype (at least another 4 months of work) it would essentially be one feature of an existing language learning application. Maybe I could do that one feature better and differentiate on that, maybe not.
I'm just really flabbergasted that this happened, and I'm not sure how to proceed. I mean I learned a fair deal of engineering skills from my work thus far, but I'm unsure how to turn this into a business that I can approach investors with.
"Oh, so what you're building already exists as a part of this other application..."
"But I'm gonna make it much better, I swear!"
Like if I were to continue with this project, I'm not sure how I could convince anyone to invest in it. Given the circumstances, would nothing short of a full prototype (mobile app) that I could put in peoples' hands be sufficient to convince them of the potential?
Thanks for any advice, I've never run into this situation before.
