GroundWork Open Source Closes $5 Million in Series D Financing Led By Canaan Partners

SAN FRANCISCO--(Business Wire)--
GroundWork Open Source, Inc. (GWOS, www.gwos.com), the leader in commercial open
source systems and network management software, today announced it has secured
$5 million in its fourth round of venture capital financing. The series D
financing, which was led by Canaan Partners, includes past investors Mayfield,
JAFCO Ventures and SAP Ventures. The latest investment will be used to help
further execute on GWOS` vision of delivering a disruptive solution that
eliminates IT administration isolation, providing a unified platform based on
open source, open standards and a thriving community as viable resources.

"GWOS has matured greatly in the last five years, and has completed some
substantial programs that are required to build an impressive business," said
Deepak Kamra, general partner of Canaan Partners. "We look forward to GWOS`
continued success and growth."

Over the past year, GWOS has made huge strides as a market leader in the
commercial open source IT monitoring arena. Just this past month GWOS reached
two milestones that will change the face of the company -- the development and
launch of www.MonitoringForge.org and a complete platform switch to JBoss in its
flagship product, GroundWork Monitor 6.0. These major successes flank the
seeding of new executive leadership, and participation in the Microsoft System
Center Alliance program. GWOS was featured in this year`s Gartner Magic Quadrant
for IT Event Correlation and Analysis and was recognized in Gartners` Hype Cycle
for IT Operations Management.

"We are pleased to provide our community with a powerful solution that matches
their diverse data center management need," said Peter Jackson, CEO of GWOS.
"Our team is committed to delivering the best solution to our users by
leveraging the center point of open source - the transparent and accessible
knowledge. Look for more great things from GWOS that will change how IT
monitoring will be done."
