A former Wall Street analyst made a $145 million trade of a lifetime to join Snap

Snapchat's parent company Snap Inc. has set in motion what could be the biggest tech flotation in years.

The filing for its initial public offering revealed the compensation of Imran Khan, a former JPMorgan research analyst turned Credit Suisse technology banker, who moved the company in January 2015 as chief strategy officer.

Now, for a bit of background, Khan made the kind of move many on Wall Street dream of, swapping a job in finance for a big role at a fast-growing startup.

Others have done the same. Anthony Noto, a Goldman Sachs banker became Twitter's CFO in 2014, and Ruth Porat became Alphabet's finance chief last year.

But for Khan, who worked on the IPO of Alibaba Group, Groupon and China's Weibo before he moved to Snap, this trade is going to pay off like no other.

Khan received $145.3 million in stock awards in 2015, according to the filing, in addition to $230,000 in salary. In 2016, he received a $5.3 million bonus, in addition to $241,539 in salary.

Khan is sure to be the envy of Wall Street.
