Work Experience

Note: With the exception of VaynerMedia, I have been a founding member and technical lead of every company listed in this section. As a founder and CTO, my responsibilities ranged from fundraising and investor relations to hiring, project management and software development.

September, 2011 - Present

Which Ventures, Inc. -

Technical Co-Founder & CTO is a social recommendation utility that allows consumers to make better informed purchasing decisions by leveraging the expertise of their social network. I originally co-founded Villij in 2006. One year later it was accepted into TechStars. The project was shelved for a few years while I worked on other ventures (see below). In 2012 Which Ventures Inc ( announced that it had acquired Villij. As the CTO at Which Ventures, I hired the entire development team, worked with management to rethink the product and eventually rebuilt Villij from the ground up. Business Insider later named Villij one of the most successful startups to come out of TechStars.

October, 2010 - Present

RevHarvest Media, LLC

Co-Founder & CTO

RevHarvest is a performance-based ad network co-founded by myself and Frankie Brannon. I assisted with business development and was also fully responsible for RevHarvest's proprietary ad serving and optimization technology. I architected and developed the technology from scratch to fulfill our specific requirements, which included serving millions of ads across multiple high traffic publishers. Needless to say, the project offered several unique technical challenges that were extremely rewarding to overcome. Incidentally, building on this experience, Frankie went on to join the Obama campaign's digital display ad team during the 2012 election.

October, 2010 - Present

Founder / Advisor is a music video discovery service and fan-driven promotional platform that is working to redefine the way fans gain access to and connect with their favorite artists. I started FanSignal as a side project in the fall of 2010 with a small seed investment from Gary Vaynerchuk. In 2011 Phase One Network took a 50% equity position in the project and has since agressively worked to mature and commercially launch the site. Although I do not currently maintain an official position at FanSignal, I am still actively involved in advising Phase One's management team as well as the development team, which I helped put in place.

June, 2010 - October, 2010

VaynerMedia, LLC

Entrepreneur in Residence / Software Engineer

VaynerMedia is a national social media agency co-founded by Gary Vaynerchuk and his brother AJ. In late 2009 VaynerMedia took an equity position in one of the companies that I cofounded (Olive Interactive, LLC - see below). Prior to selling Olive's consumer facing and enterprise solutions (see below) to a Canadian SEO company, I temporarily joined VaynerMedia as a software engineer and entrepreneur in residence. Between June of 2010 and November of that year I worked on multiple internal projects for the firm.

April, 2008 - Present

Olive Interactive, LLC

Co-Founder / CTO

Olive Interactive, LLC is an IP holdings company co-founded in 2008 by myself, Sara Czyzewicz and Anthony Dimitre. Orginally the company offered web-based services that helped businesses and individuals develop, manage, track and monetize their social media presence. Olive's primary offering was, a B2B paid service that proliferated a brand across hundreds of the most popular social media and social networking sites at once. Olive also offered a free consumer-facing service called Both DandyID and were acquired in 2011 by a Canadian SEO company (my NDA prohibits further disclosure).

June, 2006 - April, 2008

Localcents, Inc

Co-Founder / CTO

Between 2006 and early 2008 Localcents, Inc. created two consumer facing applications: and (now dormant) was a free classifieds and local deal site (a much more novel concept back in 2006). (acquired by Which Ventures, Inc. in 2012) started out as a people and content recommendation engine for the distributed web. In 2007 the company was accepted into the inaugural class of TechStars, a seed stage mentor-driven investment fund.

2003 - 2006

Kalbay Systems


I founded Kalbay Systems while attending Western Washington University in 2003. Kalbay was a consulting firm that specialized in creating custom web-based business process solutions. We had a wide variety of clients, including many in the real estate and manufacturing industries. We assisted Catholic Community Services with an early web-based fundraising campaign. We also did some interesting work for a boutique financial firm. In addition we built a remarkably successful proprietary data-driven sales solution for a local contracting firm. I shutdown Kalbay after Localcents received funding in 2006.
