A mobile CRM application built for businesses of all sizes, Perx aims to help merchants acquire, engage and grow their customer base through mobile. Businesses use Perx’s suite of marketing tools, which includes promotions, customer surveys, scratch cards, and loyalty programs, to harvest customer data like email addresses and Facebook accounts, along with birthdays, gender, and NPS. This information is then funneled into the mobile CRM system and used to power follow-up promotions and social campaigns. Perx differentiates itself from competitors with its focus on mobile and its emphasis on working with businesses of all sizes, including smaller merchants. The free download is available on the website. A demo is also available.
