Q.  We own a company that deals with recruiting and employment contacts. We would like to expand to other fields of establishing contacts, since in essence, we already have the infrastructure and computing services to do so.
Is it permitted to engage in marriage matching and dating services for Non Jews?
A. Poskim disagree if there is a prohibition on arranging dating and matching of couples for Gentiles, especially for those that do not comply with the Seven Noahide mitzvos.
Beth Sheorim (Y.D. 227) and others mention that the prohibition of ‘Lifnei Iver’ or placing a stumbling block in front of the blind likely applies, since they may not be careful with observing moral and other rulings.
However, Chavas Yoir (185) and others permit.
There are other issues of modesty involved, since usually, this type of services involves the publicizing of attractive pictures to promote the interest of the clients, so it is better to avoid engaging in it.
