Equity Private Placement Platforms?

[Meg Epstein]

I am a commercial real estate developer in Nashville, doing "boutique" commercial deals between $10m- $50m, with equity placements between $1.5m- $5m. In the past I have raised equity through individual investors with a private placement structure. Now, that I am scaling-up, I am looking to expand my network. I have come across several online broker-dealer platforms, and wondered if anyone has any experience using them? 

I am considering Wealthforge.com or www.militellocapital.com - these apparently open your investments to their network while creating a platform for people to manage their investments from. This is NOT crowdfunding. I just wanted to see if anyone had any experience in online equity platforms before I chose one or make the investment. Thank you!
