He was a faculty member at the University of Pennsylvania. He was elected as a member of the American Philosophical Society in 1797, and a Fellow of the American Academy of Arts and Sciences in 1824.

In 1809, Seybert was elected to the 11th United States Congress as a Democratic-Republican representative for Pennsylvania's 1st congressional district to fill the vacancy caused by the resignation of Benjamin Say. In the fall of 1811, he reassured President James Madison that his state had military gear and production to meet war needs. He was reelected to the Twelfth and Thirteenth Congresses.

Mineralogy Seybert established the first mineralogy collection in the United States in the 1790s. The collection contained over 1,725 crystals and rocks. The noted mineralogist, Benjamin Silliman, was known to have traveled to Philadelphia to view the collection,

The University of Pennsylvania philosophy department named a chair in the department the Adam Seybert Professor in Moral and Intellectual Philosophy. The chair was funded by Adam's son, Henry Seybert. The duties of the chair included hosting the Adam Seybert committee which investigated the possibility of the spirit world. The committee met from 1883 to 1887 but was unable to discover any evidence and subsequent holders of the chair were freed from continuing the investigations.
