Hummingbird Ltd. (previously NASDAQ: HUMC, TSX: HUM) is a subsidiary of OpenText and is a provider of enterprise software products including Exceed.

Initially founded as a consulting business in 1984, Hummingbird moved into the connectivity market.

Customers include IBM, NASA, Morgan Stanley, Boeing, The Walt Disney Company, and the Government of Canada[citation needed].

Hummingbird was one of many vendors of X server and Unix connectivity solutions for Windows-based computers, with its eXceed product being regarded as "an excellent all-round product" in the form of eXceed/W at version 3.3.3 in one 1994 review.

The product provided an X server alongside other traditional TCP/IP-based applications such as FTP and telnet clients, supporting the wide range of TCP/IP stacks available for Windows at that time, requiring a minimum system specification of Windows 3.0 running on an Intel 80286-based PC with 2 MB of RAM.
