    Bilberrry

    Founded in 2010 in Seattle, Billberry is a software development studio creating custom software, web apps, and digital products in partnership with some of the world's biggest brands. They have a veteran team of fewer than 50 strategists, designers, and developers who work in partnership with clients to help them grow, innovate, and move their businesses forward. Clients include businesses of all sizes in various industries, including business services, consumer products and services, and financial services.

    Notable Project

    A wedding registry company wasn't satisfied with its developers and needed to get its website out of beta quickly. Bilberrry built a custom PHP website and updated the old website. The new website has a feature that syncs with large national retailers to provide registry information. Bilberry now maintains and updates both websites. 

    "Other developers we’ve seen have said they could build something, but never completed it, giving us 'maybes' or reasons why they shouldn’t be building it. That’s never happened with Bilberrry." – CEO, Wedding Registry Company

Their company consists of a team of 22 people who specialize in web development, mobile app development, and e-commerce development.

    Notable Project

    New Normal provided design and development services for a gamification platform. The client needed to create the platform to increase sign-up for their airline client’s frequent flier program. New Normal created the platform, and integrated multiple features that the client wanted. After the company developed the platform, the airline received thousands of sign-ups, and the client launched more campaigns. 

    “With New Normal’s help, we were able to help the airlines get over 80,000 new sign-ups to its loyalty program in the month that contest ran. The success of this project allowed us to run two more similar campaigns for the client with New Normal as the software team.”
