Mike Markkula entered Apple because Jobs needed money to get the Apple II built. They needed to build inventory, and they needed to develop a marketing strategy, and distribution in order to build a business plan. Markkula worked in computer chips, and was excellent at finance, and price measures, Markkula was very successful already. When Markkula showed up he had a convertible. He wrote a business plan that centred on guesstimates of how many people would own a computer in their home. Markkula wanted Apple to balance check books, and keep receipts. The spirit of Markkula’s prediction was true.
Markkula co-signed a bank loan of $250,000. They owned 25% of the stock, and Apple was incorporated on April 1, 1976. He believed that Apple was at a start of an industry. Apple Computer was growing at an incredibly fast rate. The numbers were mind-blowing: from 2,500 Apple IIs sold in 1977, 8,000 were sold in 1978, and up to 35,000 in 1979. Remember there was no market for personal computers before! The company earned $47 million in revenues in fiscal year 1979, making Steve Jobs a millionaire on paper (he owned $7 million worth of private stock). Markkula believed that Apple would go public within 2 years, it went public on December 12, 1980 at $10 per share making over 300 people millionaires. Several VCs cashed out reaping billions in long-term capital gains. Through Markkula, Jobs learnt about marketing and sales. Importantly, Markkula did not want to start a company just to get rich.
