Intentional Software was a software company that designed tools and platforms that followed the principles of intentional programming[1] in which programmers focus on capturing the intent of users and designers, and spend as little time as possible interacting with machines and compilers.[2] Its tools included language workbenches, tools that separated software function from implementation, and allowed 'language-focused' development.[3][4] This allowed automatic rewriting of code as expert knowledge of implementation options changed.[5] The company later began developing a platform for improving productivity of software groups.

The company was co-founded by Charles Simonyi and Gregor Kiczales in 2002, and later headed by CEO Eric Anderson. However, Kiczales left the company in 2003.[6] In 2017 it had almost 100 staff.[7] On April 18, 2017, it was acquired by Microsoft,[8][9] with many of its employees joining the Microsoft Office team.

Products and services[edit]

Intentional Software developed the Domain Workbench, a language workbench for building and working with domain-specific languages,[10] and designed custom languages for clients for their particular uses.[11] They also built the Intentional Platform,[12] a platform for group productivity software.
