Mark Fernandes

Managing Director

“My first VC investment was in an open source (long before it was popular) security company. It was an absolute thrill to help build Sourcefire from a small team of developers in Maryland, to its IPO and then a $2.7B acquisition by Cisco. As an investor I have to play many roles and adapt with the entrepreneurs to the many ups-and-downs, but the theme stays the same – let’s do what it takes to build a great company together.”

Mark began his career as part of the founding team of a display company, followed by product roles at Seagate and Cisco. After his MBA, he then spent four years as a research analyst covering the software sector at Robertson Stephens and Merrill Lynch. He joined Sierra in 2002 and focuses primarily on software. Some of his prior investments include Sourcefire (IPO; M&A - Cisco $2.7B), Frontbridge and Opalis (M&A - Microsoft) and DynamicOps (M&A - VMware). Mark holds a BS from Mangalore University (India), a MS from UC Berkeley, and a MBA from Harvard University.

Tim Guleri

Managing Director

“It takes blood, sweat and tears to build a company...it is a journey I have been on personally as an entrepreneur. At a very visceral level I feel fortunate and humbled to support the visionary entrepreneurs I meet every day. I relish being a resource for my CEOs—the ‘doctor on call’ as they go through the ups and downs of building a successful company. I'm 24x7, like my entrepreneurs.”

A serial entrepreneur, Tim built two software infrastructure companies: Scopus Technology, which went public in 1995, and Octane Software, where he was Founder/CEO which he sold to Epiphany for $3.2 billion in 2000. In 2002 he became a Managing Director at Sierra. At Sierra, he's taken two companies public, Sourcefire (FIRE) and MakeMyTrip (MMYT), and has been responsible for several M&As. Tim holds a BA in Electrical Engineering from India and an MS in IEOR/Robotics from Virginia Tech. His passion (outside of his family and companies) is soccer.
