Are/were you in Austin? There was a building on Mopac with the drkoop.com logo.
The Austin company from that era that most sticks in my mind (or, craw) was Netpliance. The company where I worked did tech support for the i-Opener. More than a few co-workers plunked down their money for Netpliance’s IPO, which occurred on or around the same day that the i-Opener hack was published. (In other words, the stock tanked.) That company withered down to nothing and we had to lay off a large number of help desk staff.
(I also recall a large building with the Excite logo going up on South Congress. Excite was my search engine of choice for a minute, there.)
I’ve worked for a (different) company where (almost) everyone had been laid off, but they brought everyone back for a few hours one day to look like they were working while a prospective client toured the office. We did get a contract with that client, but it wasn’t enough to save the company.
