Lorraine Cline DeShiro
CO-FOUNDER & CHIEF STRATEGIST
For nearly four decades, Lorraine has helped construction leaders transform their companies from well-kept secrets into market authorities. She is the strategic architect behind the Contacts to Contracts Framework™.
Lorraine's career has been dedicated to understanding the unique challenges that commercial contractors face in business development. She has worked with hundreds of firms, from specialty subcontractors to large general contractors, helping them build sustainable, repeatable systems for growth.
Her expertise spans strategic positioning, client relationship management, proposal strategy, and building high-performing business development teams. She brings a rare combination of deep industry knowledge and proven marketing methodology that has generated hundreds of millions in new contract value for her clients.
Corinne Lapan
CO-FOUNDER & CHIEF TECHNOLOGIST
Corinne brings a modern, data-driven approach to construction marketing, specializing in building the technology systems that turn strategy into measurable results. She is the architect of the Petra platform.
With a background spanning software development, digital marketing, and business intelligence, Corinne recognized that the construction industry was being underserved by generic marketing tools built for other sectors.
She designed Petra from the ground up to address the specific workflows, relationship dynamics, and sales cycles unique to commercial construction. Her vision is to give every contractor access to the same caliber of marketing technology that Fortune 500 companies use—purpose-built for the way construction firms actually win work.
