Early career

Prior to 2001, Weiss was the managing director and entrepreneur in residence at Idealab, a business incubator.[4]

Weiss was vice president and general manager of Cisco's Security Technology Group, a position he assumed following Cisco's acquisition of email appliance provider IronPort Systems.[3] Weiss co-founded IronPort Systems in 2001 with Scott Banister,[2] with whom he had worked at Idealab. Over the next six years, IronPort Systems grew from two people into a company with 450 employees and a $200 million run rate.[2]

Andreessen Horowitz

Whilst at Andreessen Horowitz, Weiss has blogged on such topics as corporate transparency for All Things D[5] and enterprise startup best practices for GigaOM.[6] He serves on the boards of Distelli, Platfora, Silver Tail Systems, Bluebox, and Jumio[4] as well as Skout,[7] App.Net,[8] and Return Path.[9]

Weiss is credited with bringing to the firm 360-degree feedback performance reviews of partners by other partners, venture firms and entrepreneurs of the companies in Andreessen Horowitz's portfolio. This type of performance review is an unusual practice for venture capital firms.[10]
