UpKeep empowers hard-working technicians to be more productive through the adoption of cloud-based, mobile-first technology. Our SaaS solution is modernizing the way businesses manage and repair their facilities and equipment. Customers love our application because it gives them the ability to manage projects and work orders on-the-go. We also provide advanced reporting tools and IoT devices which enable managers to make data-driven decisions that save their businesses time and money. The first version of UpKeep was developed in 2014 by our Founder & CEO, Ryan Chan, while living in his parent's garage. He was frustrated with the outdated desktop software being used in the manufacturing plant where he worked— so he quit that job, leaned to code, and focused all of his energy on creating UpKeep. Today, we’re a Series B startup that's raised $50M in venture capital and recently surpassed 100 team members. We proudly serve important industries like manufacturing, energy, agriculture, healthcare, hospitality, transportation, public works, and building management. We have become the top-rated Computerized Maintenance Management System (CMMS) and Enterprise Asset Management (EAM) solution by constantly innovating and always putting our customers first. We believe people are our greatest asset. We strive to promote diversity, equity, and inclusion in everything we do. Fostering a welcoming and supportive work culture is major focus— which is why we've been named a "Best Place to Work" several years in a row. UpKeep has proudly taken the hard work out of 10 million work orders, and we're just getting started! Visit our website to learn more: upkeep.com
