Startup Idea: Language Learning and Host Family Network System
I worked in the private language learning field in the past and it would be nice if there were a system put in place where host families could host language learners in a foreign country while they are learning the native language.
Typically the hardest logistical factor for people trying to immerse themselves in a different culture and learn a language is where they are going to live. If some sort of system or network were already put in place (affordable but also a lot of room to make a profit) then this would encourage those people to take advantage of the program/opportunity and take that step to go abroad.
It would also make that person feel more comfortable to do so if they felt like they had a native family there for support (even though that family would probably just enter the program to try to make money. Obviously the program would screen the families for the best possible outcome).
There is definitely a market for this and it has the potential to make some money.
