Exa Corporation was a developer and distributor of
computer-aided engineering (CAE) software. Its main product was PowerFLOW, a
lattice-boltzmann derived implementation of
computational fluid dynamics (CFD), which can very accurately simulate
internal and
external flows in low-
Mach
Mach may refer to Mach number, the speed of sound in local conditions. It may also refer to:

regimes. PowerFLOW is used extensively in the international automotive and transportation industries.
On November 17, 2017,
Dassault Systèmes completed acquisition of Exa Corporation. Exa became part of Dassault's SIMULIA brand.
History
Exa was founded in November, 1991
in
Lexington, Massachusetts.
Exa raised about $2.4 million in a series of
venture capital investments from April 1993 though 1994 from
Fidelity Ventures and individuals.
More funding was obtained in 1994, 1996, 1998 and 2005, including Boston Capital Ventures as an investor.
In 1999, Stephen A. Remondi became chief executive.
The company filed for an
initial public offering in June 2012.
On September 28th, 2017,
Dassault Systèmes announced the signing of a definitive merger agreement to acquire Exa, valuing the company at about 400 million USD.
For fiscal year 2012, Exa recorded total revenues,

of $45.9 million, $14.5 million and $7.1 million, respectively.
Since generating its first commercial revenue in 1994, Exa's annual revenue had increased for 18 consecutive years.
The company was profitable in fiscal years 2011 and 2012 after recording net losses in the three preceding fiscal years.
Exa's total revenues and Adjusted EBITDA in fiscal year 2012 increased 21% and 51%, respectively, compared with fiscal year 2011.
Exa reported $61.4 million in total revenue for the full year fiscal 2015.
The company's total revenue was expected to be in the range of $64.7 million to $67.0 million for the full year fiscal 2016.

Massachusetts. The company also had U.S. offices in
Livonia,
Michigan and
Brisbane,
California, along with offices in
Europe and
Asia. Exa's European headquarters were located in
Paris,
France, and it also had European offices in
Germany,
Italy and the
United Kingdom. Exa's Asia headquarters were located in
