How to Sell to Marathon Petroleum in Texas

Marathon Petroleum operates in the Texas energy and industrial sector with a presence that touches multiple disciplines. ExecGraph tracks 319 professionals across 19 departments at this company, providing visibility into the organizational structure that most vendors spend months trying to piece together.

What vendors actually face

Like most Texas energy operators, vendor relationships here are built through a combination of procurement qualification, engineering approval, and operations buy-in. The procurement team manages the formal process, but the real influence often sits with the people who write the scope and the people who live with the equipment every day.

The departments that matter

Selling into Marathon Petroleum usually involves more than one department. The person who identifies the need, the person who writes the spec, the person who qualifies the vendor, and the person who signs the PO are rarely the same individual. Here is how the organization breaks down.

ExecGraph has mapped 9 procurement and supply chain contacts, 47 engineering contacts, 38 maintenance and reliability contacts, and 123 operations contacts at Marathon Petroleum. Each of these groups plays a different role in the buying process.

How the organization works

With 319 mapped contacts across 19 departments, the organizational structure at Marathon Petroleum includes the typical functional areas you would expect — operations, maintenance, engineering, procurement, and HSE. Understanding which individuals sit in each function and how long they have been in their role gives you context that a cold call cannot provide.

Who you need to reach

The right entry point depends on what you are selling. Commodity MRO might start with a maintenance supervisor. A new technology platform starts with engineering leadership. A major services contract goes through procurement with sign-off from operations. Knowing the seniority structure tells you how many layers sit between your contact and the decision.

When to engage

Engagement timing varies, but the general principle holds: get into the conversation before the budget is set, before the spec is locked, and before the shortlist is finalized. New hires in key positions create natural openings.
