For Greek strategic investments, what is the rule for bringing people with me to the country to run the business?

One measure is the investment amount. Another way would be bringing people by providing them a work permit due to your business enterprise.

Every investor applying for a resident permit under the Greek Golden Visa program, according to the article 16 of 4251/2014 Law, as recently amended, is eligible for the privilege of permanent residence permit for investment activity, under the condition that he will contribute to the investment with an amount of at least 250,000, available through own funds. In addition, the number of permits for executives allowed for each investment project depends on the amount of the total investor contribution. The following is a total investment cost and the maximum resident permits allowed for executives: 300,000 to 1 million, 0; 1,000,001 to 3 million, 2; 3,000,001 to 5 million, 3; 5,000,001 to 10 million, 4; 10,000,001 to 15 million, 5; 15,000,001 to 20 million, 6; 20,000,001 to 25 million, 7; 25,000,001 to 30 million, 8; 30,000,001 to 40 million, 9; over 40 million, 10.
