We are a B2B Growth Agency focused on scaleable high-expertise businesses

Why Choose a growth agency like P5?

We know mechanical equipment manufacturers and their representatives.  We have consulted in sales and marketing with Trane, Armstrong Pumps, and Aermotor Pumps.  We have owned and operated a manufacturer's representative business.  We manufactured our own chiller-boiler packaged system under the Hydronika brand and developed product selection software for engineered products.

We know consultants and experts for hire.  P5 has worked with many high-end consulting firms, often in highly specialized niches.  These firm's offerings were all considered purchases involving research and due diligence on the part of their prospects and customers. These experts included software companies, financial services, and business consultants. We operated our own consulting business for many years.  Most of the industry experience we acquired in the HVAC and plumbing equipment industry we gained by installing sales and marketing tools while turning around both sales and marketing operations.

We understand the value of utilizing software to simplify and amplify sales and marketing in the digital world.  As both sales and marketing experts, consultants, and experienced members of the mechanical equipment industry, we are uniquely positioned to help both audiences acquire new customers.  It is what we do.
