Europe's new privacy rules, called the General Data Protection Regulation (GDPR) are officially in effect. To comply with them, some small businesses and startups have had to put other work on hold while they make sure they’re not in violation. The GDPR requires companies that have European customers to get clear consent to gather their information and make data available to correct and even delete it, if the customer asks. And the fines for not complying are huge. Lawrence Coburn is CEO of a company called DoubleDutch that makes mobile apps for conferences. The apps collect location information, demographic data and sometimes contact and job information from attendees from all over the world. Coburn spoke with Marketplace Tech host Molly Wood about how much stress the GDPR has caused him.
