Large distributors manage extensive product catalogs while operating with their own terminology, processes and requirements, making it important for suppliers to understand how each operates. When distributor sellers need answers or product information, even a small delay in navigating these requirements can derail an order.
Industrial Source, Inc. (ISI) bridges these gaps by helping suppliers work effectively within the distributor ecosystem while equipping distributor sellers with the product information and subject-matter expertise they need.
A manufacturers’ representative agency specializing in industrial distribution, ISI helps suppliers build product awareness through ongoing marketing and seller engagement with MRO distributors like Grainger, Fastenal, MSC, HD Supply and Chadwell Supply.
“We want to consistently keep our suppliers’ products and messaging in the minds of the distributors,” says Doug DiVenere, senior managing partner.
The ISI team turns that awareness into sales activity by working with distributor sellers to identify applications, solve challenges within customer facilities and drive pull-through with end users. Beyond field sales, it supports onboarding, logistics scorecards, national account programs, customer service and various operational needs.
At ISI, its people are central to the value suppliers receive. Its team of approximately 40 people brings over 500 years of collective experience in industrial distribution.
ISI dedicates employees to key distributors, enabling them to master each organization’s processes, terminology, and requirements. This distributor-specific expertise helps suppliers deliver content completely, accurately and on time.
That fluency helps ISI quickly connect distributor sellers with the right information and subject-matter expertise. When a Grainger sales representative asks whether a product is available through ‘sourcing,’ for example, ISI understands the terminology and can quickly provide the information needed to keep the opportunity moving.
Making Supplier Messages Distributor-Ready
ISI applies its distributor expertise to marketing, helping suppliers translate product messaging into tools that distributor sellers can use with their customers. It maintains a brochure portal that gives distributor sellers and customers 24/7 access to current, distributor-specific materials designed to help them understand product applications, communicate solutions, and influence purchasing decisions.

When creating materials, ISI follows each distributor’s branding and formatting requirements, incorporating distributor part numbers and links to distributor product pages, making it easier to move from identifying a product solution to purchasing it.
Beyond the portal, ISI sustains product awareness through email, social media, lunch-and-learns, district meetings, and field calls, keeping suppliers’ products and solutions top of mind when customer needs arise.
Building Value for Every Stakeholder
ISI builds its team around people who genuinely want to help others win. That supports a mission to drive value across three connected relationships—the supplier, the distributor and the end user—helping each achieve its individual goals.
“We’re in the business of creating heroes. When suppliers sell to distributors and distributors sell to end users, everyone wins. Customers win by finding solutions that save them time and money,” says Steve White, managing partner.
That approach has helped ISI become a two-time Grainger Manufacturer Rep Agency of the Year.
Looking ahead, ISI plans to invest in areas that create additional value for its supplier and distributor partners. The company is tripling its marketing resources while dedicating business development managers to distributor inside sales. It is also investing in experienced talent while developing early-career professionals.
Its recognition as the Top Industrial MRO Sales Representative Agency 2026 reflects the distributor-specific expertise, full-service support and ability to consistently connect suppliers with the people and processes that move products through industrial distribution.
