Early life

Mashinsky was born in 1965 in the Soviet Union to a Jewish family. His family obtained permission to leave the country in the 1970s and later moved to Israel. From an early age, he was a tinkerer, like his father, and would tap into and use public phone lines in Israel. As a teenager, he bought confiscated goods from Ben Gurion Airport at auction and resold them for a profit.

Mashinsky attended a few different universities where he majored in electrical engineering but did not graduate. He served in the Israeli Army, where he trained as a pilot and served in the Golani Brigade, from 1984 to 1987. In 1988, he left Israel and moved to the United States.

Career

Mashinsky has worked in a variety of different industries, often focusing on popular technologies. The Wall Street Journal described him in 2022 as "a brash, confident serial entrepreneur with a constant stream of big ideas". On several occasions, Mashinsky has left his companies after a period of conflict or tension.

After relocating to New York City, Mashinsky ran a business trading contracts for delivery of chemicals such as urea, gold, and sodium cyanide. However, after the Tiananmen Square protests of 1989, the business slowed as exports of sodium cyanide from China fizzled. Mashinsky then worked at A+ Systems, a computer-based voicemail software company for phone carriers.

Telecommunications companies

Mashinsky was an early developer of voice over Internet Protocol (VOIP). In the early 1990s, he founded VoiceSmart, one of the first companies to offer computer-based VOIP phone service. By 1993, Mashinsky had realized the potential for a commodity market for international telephone capacity. So, in 1996, Mashinsky founded Arbinet, a marketplace for VoIP telephone service. The platform was one of the first to allow telecommunication companies to trade minutes. In November 1997, Arbinet began offering a similar service for data connectivity, allowing the more than 400 T1 lines connected to its New York hub to exchange their unused bandwidth.

In 2005, he sold his stake in Arbinet and used part of the profits from the sale to start GroundLink. The company allowed people to book limousine and car service from a smartphone or computer. Mashinsky was inspired to start the company after a car he had reserved for himself and his wife failed to pick them up, along with a business associate he was trying to impress, from the airport. In 2010, Mashinsky organized a joint venture between GroundLink and several limousine and car service companies. These companies with LimoRes Car & Limo Service, a company Mashinsky also founded, installed free Wi-Fi service funded solely by sales of advertising. He also partnered with Gogo Inflight Internet to offer the free service on US flights.

Mashinsky's company Q-Wireless is one of the four companies that made up Transit Wireless, a joint venture to install wireless cellphone and free Wi-Fi internet service in the New York City Subway system. It took Mashinsky three years to convince the MTA to determine if there was a demand for cell phone service inside the subway system, and two more years for the authority to request a proposal. By 2010, his company had received a contract to install the service at 277 below-ground subway stations in New York City.

In April 2014, Mashinsky was named to the board of directors of Novatel, a provider of Wi-Fi hotspot products. He was appointed CEO in June of that year. In October 2015, Mashinsky left his position at Novatel after a year and a half as CEO of the company. In a 2018 deposition, Mashinsky said that he was terminated from his post because he refused to move from New York to Novatel's San Diego headquarters.
