Debt Placement Agent

Hey all - Looking for personal experiences or knowledge of a debt fund placement group that focuses on smaller placements. Our fund invests across the capital structure targeting mid-teens IRRs. We are already a decent ways through our fundraise and have a handful of folks coming into our next close. We are evaluating bringing on a group to help us raise an additional $100-$200M on the back end, if feasible. Most of my relationships are at big shops who start at a $500M raise. Any thoughts here? Thanks in advance.
