OptimumHQ is for mid-sized and serious small businesses that are struggling with packaged software and spreadsheets to run their business. OptimumHQ is the leading business solution platform that allows customers (or a partner) to rapidly create custom business solutions for complex business problems. Unlike custom development and hefty enterprise software, OptimumHQ delivers powerful, tailored solutions in days or weeks, not months or years at a much lower cost and with no custom code. We believe that custom software is critical to business success, but companies are getting ripped off by high-end software and custom dev shops. OptimumHQ is a disruptor in the industry, an emerging middle ground between off-the-shelf solutions that don't serve the customer's needs and monstrously expensive and clunky custom software.
