My father worked for Sperry, who changed their name to Unisys in the mid 80s... He was a tech and when the company was shifting because of big blue and the Reagan administration not protecting monopolies, switched over to Commodore repair.
Mid-80s....My first modem was a 300 baud that I connected a few times to QLink. It was long distance, so that wasn't a common thing for me to do since I wasn't paying the bill. I had a stack of C64s...
Because computers were somewhat expensive, I had a 286 after that and used lynx, but it really wasn't until the 486 days that I was truly online because I had a friend who's brother worked for Compudyne and sister who worked for Prodigy. I got on with Compuserve and we also burned through a lot of AOL time... Not pioneers by the time we were on because the pioneers had already laid the groundwork.
The same time I was on Qlink and just getting my feet wet, a future coworker of mine was writing BITNET Relay using REXX... He was probably the closest thing to a founder that I worked with professionally because his work was said to have inspired the development of IRC.
(Another founder I could mention is Linus Torvalds....but that doesn't count because I've only met him and not worked with him on any projects.) I only consider him an internet founder because his platform has been adapted to the appliance side of cloud computing due to its open source roots.
