2/24/2018 S-1 Table of Contents Brandt Brandt is a large mechanical, electrical, and plumbing contractor that services facilities like schools and hospitals across Texas. Before adopting Dropbox, Brandt’s field technicians relied on paperwork, scanners, printers, and fax machines to communicate with their company headquarters and customers. In 2014, Brandt purchased 120 Dropbox Business licenses and deployed them on tablets for technicians on job sites to update forms and work orders in shared Dropbox folders. Brandt also integrated its own digital signature app with Dropbox to make the process even easier. Signed forms save automatically to the appropriate Dropbox shared folder, which notifies the approving supervisor. Brandt has since expanded its deployment to 250 Dropbox Business licenses, and estimates that each field technician saves up to one hour per service call on document processing. With 120 technicians each completing two service calls per day on average, Brandt calculates savings of $400,000 per year—or more than three times the annual cost of the company’s Dropbox Business subscription. “Our technicians are more efficient, our customers are getting what they need more quickly, and we are delivering to the bottom line in ways that were unforeseeable when we began this process.” Jim Stagg Vice President of Service Brandt 114 https://www.sec.gov/Archives/edgar/data/1467623/000119312518055809/d451946ds1.htm 122/235
