Refugees need job opportunities, they have skills and would love work, but can't find jobs. Create an app or website to connect refugees with local businesses who need their skills. No resumes - just the skills they have and employers looking for them.
A more specific idea is that refugees would be able to list what languages they speak and what skills the have. Employers could then select the relevant language and skill and be matched with a candidate that fits their hiring needs.
Revenue stream for this startup could be a small fees charged to the business per hire or subscription. This business model is repeatable and has no boundaries.
