Door Devil Vision

Change the homeowner’s minimum expectation of a home security system; by...making available a defensive component which is so easy- to- install, effective & affordable that it defies common sense to exclude it from any home security package or preparation.

Sales & Product Development: Tom Fairless/Pioneer Products, LLC

Tom Fairless (owner of Pioneer Products, LLC) has been instrumental in nearly every facet of the Door Devil’s evolution which includes but not limited to product development and building a network with Law enforcement agencies, Locksmiths & handymen.

Finance: Gilhang Financial Group

Door Devil Financial Partner Gilhang & Hays

When other Investment groups would not listen; Gilhang Financial Group’s leadership listened and had the ability to see the market potential and Door Devil’s vision; and how it could materially impact the $100B Home Security industry. They provided guidance and investor contacts in our period of greatest need. I will be eternally grateful for their trust and belief in me, personally. We would have never succeeded without them.  Their ability to see the value where others do not is just one of the reasons to trust The Gilhang Group.
