Our Story

CEO Dustin D. Trammell and Chief of Operations Christina Johnson-Sullivan launched Trammell Ventures in 2011 to manage investments in engineering project incubation and external enterprises.

Dustin brings over 15 years of experience in advanced information security research and architecting secure networks and systems. Having long held an interest in cryptography and privacy he became one of the initial contributors to and adopters of Bitcoin. His early involvement led him to need to make a public statement in 2013 that he was not Satoshi Nakamoto. His knowledge of blockchain and information security technologies, along with his passion for the bodyhacking movement, serve as a wellspring that inspire and inform his investment and inception decisions.

Christina has been heavily involved with the business side of information security since 2009 and is a welcome presence at major industry conferences. As part of Trammell Ventures she leverages her extensive network of government and corporate cybersecurity contacts to secure partnerships and harnesses her extensive business management experience to oversee the day-to-day business of the enterprise.

Drawing on their deep network of connections in the cybersecurity space, Dustin and Christina brought a new conference to Austin, Texas. Currently in its sixth year, InfoSec Southwest has been sponsored by household names including Amazon, Cisco, and Trend Micro. The Trammell Ventures events production portfolio expanded in 2016 to include BodyHacking Con, which brings together doctors, artists, scientists, and experimenters in the domain of human augmentation and modification technologies. Both conferences are produced by Rogue Signal, an events production and gamification company incubated by Trammell Ventures.

Christopher S. Calicott concentrates on the venture capital side of the enterprise as Managing Director of the company’s first venture fund, with special focus on information and cyber security, blockchain technology, and machine intelligence venture investments.

Product development and incubation are the core of Trammell Ventures engineering labs. Scott Boone brings twenty years of experience in systems, network and software research, engineering, and management to oversee the development of the company’s portfolio of incubation products and leads Flannel Division, the professional services arm of Trammell Ventures.
