Named customers and case studies include Equity Residential, LeFrak, TWG, Summit Property Management and BLDG Partners. Equity Residential is quoted reporting more than 1.5 million customer interactions a year, 90 per cent of prospect workflows automated and about 14 million dollars in payroll savings. The company also says it has more than 40 engineers.
