How Retailers Can Fight Back, Survive and Thrive in a Digital World

Online shopping continues to rapidly grow in the U.S. and global markets, yet most retailers are still figuring out how to do business in an omnichannel world.

More than half of every $1 of retail e-commerce growth in the U.S. is already earned by Amazon, according to a recent report by Macquarie Research.

Stakeholder Experience Design

Because Rangle is a consultancy, we have the opportunity to work with many different clients over a relatively short period. Over the last two years, we've been able to refine a lean discovery process that allows us to rapidly align our teams with our clients and lay the groundwork for establishing clear communication channels on day one.
