This is the description of Michael Bloomberg's description on Wikipedia page about his business career:
In 1973, Bloomberg became a
general partner at
Salomon Brothers, a
bulge-bracket Wall Street investment bank, where he headed
equity trading and, later,
systems development. In 1981, Salomon Brothers was bought
[14] and Bloomberg was laid off from the
investment bank and given a $10 million severance package.
[15] Using this money, Bloomberg went on to set up a company named Innovative Market Systems. His business plan was based on the realization that
Wall Street (and the financial community generally) was willing to pay for high quality business information, delivered as quickly as possible and in as many usable forms possible, via technology (e.g., graphs of highly specific trends).
[16] In 1982,
Merrill Lynch became the new company's first customer, installing 22 of the company's Market Master terminals and investing $30 million in the company. The company was renamed
Bloomberg L.P. in 1987.
[17] By 1990, it had installed 8,000 terminals.
[18] Over the years, ancillary products including Bloomberg News, Bloomberg Message, and Bloomberg Tradebook were launched.
However, unspoken story about the first Bloomberg terminal can be found in Bloomberg's autobiography. He was angry when he was let go at Salomon Brothers' acquisition. He and a few engineers at Salomon teamed together to build the first terminal. When the time came to show off to Merrill, the terminal didn't work a day before! That was a definitely a disaster. Somehow, during the demo, engineers made the screen display something that prevented the demo from being a complete failure. That was sweating experience.
Another demo from Dean Kamen, who made his name by founding FIRST, for For Inspiration and Recognition of Science and Technology. The organization is to stop American's brain drain and try to boost innovation. Kamen started as a teenage business when landing a light show project at the Hayden Planetarium in New York City. He barged in to the office of the museum's chairman's office to convince him that the light show systems needed to be upgraded. All he got was rebuffing. Undeterred, he then bought parts from Radio Shack and built the first light show system. He used his employee pass to get into the Planetarium and tested his system. The system was short circuited and blasted into smoke. After unknown number of attempts, he finally got it working. When inviting the chairman again for the demo, the chairman was angry. Kamen didn't flee away by the chairman's fury but showed the automatic system. The chairman was impressed by the design and approved Kamen's light show project. Kamen was paid $2000 for each system. That was his first business ever.
"Frog kiss", Kamen called it that kissing many frogs before finding the prince, is a state of norm in many business.
