Salient Software

Extracted from the Wikipedia article DiskDoubler.
Realizing they needed real marketing muscle, they approached Symantec, who agreed to include it in their Symantec Utilities for Macintosh (SUM) package for a pittance. Unimpressed by the offer, they instead asked Guy Kawasaki to front them a $25,000 development loan, raised a similar amount on their own, and formed Salient Software. After four months sales were over $50,000 a month. When System 7 shipped in June 1991 sales took off, as the new system was rather hungry for drive space. The company was eventually sold to Fifth Generation Systems in 1992. They also repackaged it in a suite as SuperDoubler 4.0, including AutoDoubler, DiskDoubler, and a file-copy speedup known as CopyDoubler. For some time, DiskDoubler was the second-best selling product on the Mac, second only to After Dark, the popular screen saver. Fifth Generation was later sold, somewhat ironically, to Symantec, who re-released it as a fat binary as Norton DiskDoubler Pro 1.1. Symantec "sat" on the product and it slowly disappeared over the next year.
