Meebo, Inc. – User Experience Designer & Engineer

Meebo was an instant messaging application started in the early days of web 2.0 acquired by Google on June 4, 2012. The original Meebo product line is no longer available but the team still works under Google.

Krieger’s first full-time role after attending college was working as a UI Experience Designer and Developer at Meebo, Inc. His duties at Meebo included prototyping and testing various new products and later designing and developing the internal and external statistic and visualization tools for Meebo’s partners.

Instagram – Developer, Co-Founder, CTO

Krieger was instrumental in the original creation of the Instagram user interface and codebase. In 2010, working with Kevin Systrom, they started a small photo sharing and editing application. The idea came from another application they were working on that had photo-sharing aspects along with other features.

In the early stages of the company’s growth, Mike was the primary technical employee. Instagram was a small startup that began its life as Burbon which allowed users to check-in, post plans, and share photographs. Krieger was the first employee to join the startup after Systrom gained initial funding for the venture.

Krieger and Systrom previously knew each other from Stanford University. They decided to pivot the direction of Burbon and focus on the photo-sharing aspect of the application. Photo sharing and filtering photos in a mobile app weren’t commonplace at that time.

After Instagram was conceptualized, created, and launched it grew very rapidly. Users flooded onto the app and two years after Instagram was born Facebook acquired it. Krieger was the pioneering developer for the application and leader of the technical side of the business.

Mike served as the CTO, growing the engineering team to over four hundred employees until leaving the company with Systrom in 2018. When Instagram was purchased by Facebook it only had six developers, Krieger transformed from a first-time manager to tech mogul CTO in just a few short years.
