Profile bio

About David Brennan

An accomplished entrepreneur and a Fortune 100 executive with a long track record of innovation and first-to-market solutions. I brought the first online booking website for consumers from property owners that offered private homes, apartments, or rooms for a short-term rental, which was recognized as one of the top 10 travel sites in the world. Additionally, I launched the first energy rate comparison website in Texas that became the standard data source for consumers and companies (even for energy companies). I pioneered the first SaaS solution for the first real-time, personal property valuations for adjusting homeowner insurance claims (22 pending patents for Business Process Reengineering BPR). As an executive, I have experience running multi-billion dollar channels, as well as start-ups leading to acquisition. My prior experience includes joining a VC-backed mobile software company with zero revenue, Quickoffice, to lead in its market launch, achieving #1 app ranking for business for iOS/Android, and eventual acquisition by Google - repurposing the acquired company’s IP into Google Sheets, Docs, and Slides. Afterward, I joined T-Mobile as their VP of eCommerce to transform the digital business for the MetroPCS brand. I've been recognized by industry publications, requested by my alma mater to become a professor for entrepreneurship, and industry leaders for my expertise in e-commerce, innovation in technical solutions, and go-to-market strategies.H9 Technologies is my next endeavor in digital transformation.
