David Koretz, a 28-year-old who started his first business when he was 14, grew up watching his family members struggle with technological issues at their companies. That's why BlueTie, the company Koretz founded in 1999, makes Web-based software that lets businesses send e-mail and share files without installing any equipment. BlueTie serves more than 230,000 small and midsize businesses, including his parents' Rochester-based collection agency, C&C Adjustment Bureau.
Things I can't live without:
"I like that Panerai designed watches for the Italian Navy in the 1930s. This one isn't for the dainty. I'm 6 feet 4, so it's in proportion." About $6,000, panerai.com
"I own more than 1,000 wine bottles, which I scan into a program, CellarTracker, that tells me when each will taste best." $250, serialio.com
"I'm way too OCD. Even though I have a housekeeper, I program three robots to clean my house in the morning." $399 each, irobot.com
What I covet:
"I race cars about 10 days a year. It's relaxing. When you're going 140 miles an hour into a corner, all you're thinking about is the corner. This Ferrari is a little too flashy for me, but the sound of the engine at full throttle is intoxicating. It's fast enough to race competitively and beautiful enough to drive on the street." About $200,000, ferrariusa.com
