INB, formerly Illinois National Bank, provides personal and commercial banking products

Though founded in 1999, Jim Antonacci says you have to go back to 1986-87 to start the story of today's INB. Bank acquisitions were common then. Bigger banks were buying the smaller banks, and that included community banks like Illinois National Bank, known even back then simply as "INB." Even though a major force in Springfield from the late 1800s, INB was a small national bank. In 1988, the bank became part of a multi-bank holding company. That holding company was eventually sold to a large bank. That large bank was purchased by a larger bank in 1998. Though Jim and others were talking about starting a bank in the 80s, it wasn’t until the 1998 buyout that he and his colleagues decided it was time to start a new type of community bank.
