We built Maxwell to change the game for small and midsize mortgage lenders — whether you originate $300M or $3B. Today our digital mortgage platform powers hundreds of mortgage lending institutions nationwide, from non-depository mortgage banks, to credit unions, to brokers, to community banks. We work to make them, and their employees, the real heroes who enable homeowners to achieve the American Dream. And we’re just getting started. Maxwell was founded in 2015 by homebuyers who were shocked by the complexity of the mortgage process for borrowers and lending teams alike. Somehow, in the mix of paperwork, points and process, the humanity and emotion of the largest financing decision of a person’s life had been lost. After spending a year with over 1,000 mortgage professionals, the founding team realized we needed to focus on making the people who make a difference really shine. Now, we employ a world-class team of software experts and mortgage professionals who pull up our socks every morning to do just that. We’re privileged that our company has been recognized by HousingWire, Progress in Lending, MReport, and others as a leading innovator in our industry. At the end of the day, we are a committed team doing honest work that really matters in the real world — one lender, one borrower, one homeowner at a time. And it works.

Stack Lighting created a spatial intelligence platform to track activity for indoor spaces. The platform was an end-to-end system based on embedding Doppler radar into light bulbs, then aggregating and analyzing the data in the Stack Lighting cloud. With both control and machine learning layers, the insights were available through a robust set of APIs allowing real-time and responsive applications to be created. Applications were developed for home and building automation, as well as services such as security, space usage analytics and healthcare. Stack Lighting shipped multiple consumer and commercial products as well as enabled partner manufacturers and service providers to expand their offerings with the technology. Stack Lighting was acquired by Philips Lighting in 2017.
