Glitch, Inc.

Glitch, Inc. (previously known as Fog Creek Software, Inc.) was a software company specializing in project management tools. Its products included project management and content management, and code review tools. Fastly acquired the company in 2022, however, the company announced it was shutting down in July 2025.

The company's original name was Fog Creek. Based in New York City, Fog Creek was founded in 2000 as a consulting company by Joel Spolsky and Michael Pryor. As the consulting market started to dry up due to the collapse of the Dot-com bubble, Fog Creek moved to a product-based business. In December 2016 Anil Dash was appointed CEO. Fog Creek's offices are located in the Financial District of Manhattan. On September 25, 2018, the company was officially renamed Glitch after its flagship product. Glitch staff announced intentions to unionize with the Communications Workers of America in early 2020 as part of the Campaign to Organize Digital Employees. The company voluntarily recognized their union. Around the same time, the company laid off a third of its staff during the COVID-19 pandemic. In February 2021, Glitch workers signed a collective bargaining agreement with the company. According to the Communications Workers of America (CWA), this is the first agreement signed by white collar tech workers in the United States.

Cloud services Fastly, known for its content delivery network, acquired Glitch, as announced in May 2022. CEO Anil Dash became Fastly's VP of developer experience. Glitch's staff had declined since 2020 from 50 to 14 employees, all of whom joined Fastly. The union dissolved prior to the acquisition when its collective bargaining agreement expired and the union's three remaining members decided not to pursue another agreement.

Fog Creek Copilot was a remote assistance service offered by Fog Creek Software. It launched on August 8, 2005.

Originally known as Project Aardvark, Fog Creek Copilot was developed by a group of summer interns at Fog Creek Software. Fog Creek's founder, Joel Spolsky, wanted to give his interns the experience of taking a project through its entire lifecycle from inception, to mature released product. The interns set up a blog, called Project Aardvark, where they posted updates on the progress of their project, even though at that time the details were still secret.

On July 1, 2005, the Project Aardvark team revealed that they were working on a remote assistance system for consumer use.
