Romanow launched her first Business, The Tea Room, a zero consumer waste coffee shop, in 2006 while studying at Queen's University. Romanow then partnered with two colleagues from her engineering class, Anatoliy Melnichuk and Ryan Marien. Together, they founded Evandale Caviar, Buytopia.ca, and SnapSaves without raising any external capital. Romanow graduated and started Evandale Caviar, a vertically integrated fishery that distributed high end sturgeon caviar to luxury hotels and restaurants. She then became the Director of Strategy for Sears Canada. In 2011, Romanow started Buytopia.ca which, by 2013, had 2.5M subscribers and had provided over $100M in savings through deals for products, services, events, and travel, with merchants including brands like Cirque du Soleil, Porter Airlines, and Staples. Buytopia also grew by acquiring six competitors. Romanow started SnapSaves, a mobile couponing app that gives shoppers cash back when they buy certain items in the grocery store by partnering with consumer packaged goods companies. Groupon purchased SnapSaves in June 2014, relaunched in the U.S. as Snap by Groupon.
