Infonautics, Inc. was an information services company, founded in 1992 by Marvin Weinberger,[2] Lawrence Husick, and Josh Kopelman,[3][4] and had its headquarters in Wayne, Pennsylvania, United States.

The company's executives included Van Morris (CEO), Ram Mohan (COO/CTO),[6] Frederica O'Brien (CFO), and Gerard Lewis (General Counsel).

In 1990, Telebase founder Weinberger and outside counsel Husick conceived of Homework Helper, a $10 per month unlimited research service having a large multimedia database and a natural language user interface.

Working with Brewster Kahle, a protocol was developed to run on the Thinking Machines massively parallel computer system, but in late early 1991, Conquest Software demonstrated its semantic search engine and a change in direction ensued.

The company created online services Homework Helper on Prodigy,[11][12] Encyclopedia.com,[13] Electric Library,[14] and CompanySleuth.
