He was indeed a business man, he took early retirement from Navy, in Navy he was an engineer. After retirement he invested his pension funds and savings into a small ship.
Back in those times Global economy was about to boom and India was going to expand the trade with Iran in a significant way. So Kulbhushan invested lots of money in the Boat. I can't recall the name of his boat as of now, but It was supposed to ship goods between India and Iran.
Then came American sanctions on Iran and all the prospects of trade with Iran went up in smoke. Kulbhusan among many other suffered a great loss.
He had some contacts in Navy and approached RAW to get an entry. He told officers of RAW that he would help them by spying on Gwadar and Chinese development there, If paid well. RAW refused his application and sent him back.
And that's the closest Kulbhushan came to intelligence gathering agency. He was kidnapped in Iran, after Pakis or I should say the Chinese picked him talking to his home in Marathi. They traced him in Iran and baited him to an isolated place and kidnapped him through Pakistani smuggling gangs. Weather he was there for some deals with those smugglers or other motive is unclear.
He was kidnapped in Iran is what even German ambassador to Pakistan confirmed.
It is not that ISPR or ISI doesn't know who he really is, but they are making a show of him. As to warn any Indian officer and Indian Government who would be sent on sabotage and subversive operations in Baluchistan area, about which they are more paranoid than what the reality is on ground.
