He is an Egyptian mogul who is little known outside the region.

The tycoon, Ibrahim al-Organi, chairman of Organi Group, oversees a vast network of companies involved in construction, real estate and security. He maintains close connections to top Egyptian officials, three people who have tracked the relationship and who spoke on condition of anonymity to protect their work in the region.

But it is Hala — a company that Organi Group has listed as one of its own — that has drawn the most scrutiny. Hala has emerged as a lifeline for Palestinians who are trying to escape war-torn Gaza but has also been accused of squeezing desperate people with exorbitant fees. In an interview this month, Mr. Organi spoke at length and in detail about Hala’s activities, though he said that his role in the company was limited and that he was just one of many shareholders.

Officials at Hala did not respond to questions sent by email.

Hala had long been listed on Organi Group’s website as one of the conglomerate’s companies, but the reference appeared to have been removed recently. Organi Group did not respond to a request for comment about why it had removed Hala from the website.

Organi Group has at least eight businesses. The company lists Mr. Organi as its chairman and his son, Essameldin Organi, as the chief executive.

The older Mr. Organi, according to the company’s website, has built “a diverse business empire acting as an inseparable backbone to the Egyptian economy in countless fields.”

In the interview in his office in Cairo, Mr. Organi described Hala as a tourism company, “just like any company that exists at an airport.” It was set up in 2017, he said, to provide V.I.P. services to Palestinian travelers who wanted an upgraded experience crossing through Rafah, the southernmost city in Gaza.
