Allaire was founded by Jeremy Allaire and Joseph J. Allaire in Minnesota, and was later headquartered in Cambridge, then Newton, Massachusetts. Allaire first released Cold Fusion 1.0 in 1995.[1] In March 1997, Allaire acquired HomeSite,[2] which became the foundation of ColdFusion Studio, an integrated development environment for the ColdFusion platform. On June 15, 1999, Allaire announced the acquisition of Live Software, the developer of JRun.[3]

Macromedia absorbed Allaire Corporation through a merger that was completed on March 20, 2001.[4] Jeremy Allaire became Chief Technology Officer of Macromedia from 2001 to 2003,[5] and remained involved with the company as founder emeritus.[6] Macromedia itself was acquired by Adobe Systems in December 2005.[7]
