Anyone heard of Rainstar Capital Group?

I got added on Lindedin by someone who works there and after doing some research I'm confused about what they do. The website describes them as "a multi strategy private equity firm based in Grand Rapids, Michigan that makes investments in consumer distressed debt portfolios, small business merchant cash advances, distressed mortgages, high growth companies and residential and commercial real estate", but they have all kinds of sketchy marketing material and most of the MDs only have small business lending experience. At best, I think this company is a small asset based lender calling themselves a private equity company. I couldn't find anything else about them online so I was wondering if anyone had heard of them.
