Enterprise Technology Sales Leader

MartyManwiller

I sell enterprise technology into the world's largest retailers —
and I know exactly how they buy it.

15+ years. Both sides of the table. Nearly a decade inside Walmart managing $829M in spend, followed by vendor-side success growing national accounts at Honeywell and Johnson Controls. AI platforms, SaaS, RFID, and managed services.

About

The Buyer Who Became the Seller

Most enterprise technology salespeople learn to sell to large retailers. I spent nearly a decade being the customer — managing hundreds of millions in indirect spend inside Walmart across construction, facilities, technology, and building systems. I sat in the exact seat your salespeople are trying to reach.

That dual perspective is rare. I understand how enterprise technology decisions get made at scale — the procurement cycles, the stakeholder dynamics, the ROI frameworks, the internal politics — because I lived it from the inside. When I moved to the vendor side at Johnson Controls and Honeywell, I applied that institutional knowledge to grow national accounts, expand program footprints, and close complex multi-year deals.

I've sold AI-driven energy management platforms, SaaS solutions, RFID-enabled inventory systems, managed services, and enterprise building automation technology to C-suite and senior operations leadership at Walmart — including integrating an AI monitoring solution directly into Walmart's data lake and scaling it nationally to 3,100 locations.

I know what moves the needle and what doesn't. I build executive relationships that last, and I align technology to the business outcomes that matter to the buyer.
