Black Mountain Systems - Financial Software

Founded in 2007, Black Mountain Systems developed innovative, tailored solutions for data aggregation, process management, and business reporting.

Partnered for growth

“We’ve established ourselves as the market leader in workflow software for credit, structured credit, and alternative asset managers, and now we have a partner in Vista who will help us build upon that leadership position,” said former Black Mountain co-CEO Andy Horwitz.

State of the art platform
