Peter Cahill   |   Founder

Peter Cahill is the Founder of Clandestine Development, LLC. He was inspired to create LifeLine Response after several of his family members fell victims to assault and attack. In 2011, Peter funded research to assess how sexual and violent crimes occur. Using this data, he led a team of skilled engineers and psychologists in developing new technology that would be effective in the critical moments of a life-threatening situation. This technology was the driving force behind LifeLine Response and Peter led the charge with his tireless focus on product design. The result is a mobile application that will change the way people look at personal safety.

In addition to his work on LifeLine Response, Peter was a founding partner of TransCapital Partners, a 14 year old international, Merger and Acquisition Investment Bank with offices in Hong Kong and based in Chicago, Illinois. Over his 14 year career, he advised on transactions and divestiture strategies equaling an aggregate value of $1.3 billion. Peter has assisted several Fortune 100 companies to accelerate growth and increase market share by evaluating economic patterns in various industries, including technology, manufacturing, and transportation.

Peter studied Political Science at the University of Tennessee and multi-cultural development at Depaul University.
