Richard Holt initially ran the business that Eleanor Coade acquired. It's likely there was a handover period or continued association, as Holt possessed prior knowledge of the artificial stone production methods. The precise nature of this relationship is unclear, but he likely provided initial training or support.

John Sealy, a skilled sculptor and architect, became Coade's partner. This was a significant development as Sealy brought expertise in design and sculpture, complementing Coade's business acumen and production knowledge. The firm was known as Coade & Sealy during this period.

Coade cultivated relationships with prominent architects of the time, such as Robert Adam, James Wyatt, and Sir John Soane. These architects specified Coade Stone in their projects, contributing significantly to the company's success and widespread recognition.

Coade employed skilled sculptors and craftspeople to create the molds and models for Coade Stone products. These artisans played a crucial role in the quality and aesthetic appeal of the company's output. Names such as John Bacon the Elder and John Rossi are associated with Coade.
