A randomized controlled trial (RCT) was used to assess the impact of both cash grants and cash grants + mentorship support on programs on improving the economic and mental wellbeing outcomes of refugee and Kenyan business owners in Nairobi, Kenya. 

The study found that giving cash grants alone and giving cash grants combined with mentorship greatly improved business ownership, profits, productive assets and average monthly income for both refugees and Kenyan nationals. The greatest impact was observed on new business owners. Additionally, 1:1 mentorship was found to greatly benefit the mental wellbeing of participants, particularly Kenyan men. However, there were notable gender differences, as refugee women experienced minimal effects on business outcomes across both groups.
