Alex Mashinsky

Alex Mashinsky (born 1965) is a Ukrainian-born Israeli-American entrepreneur, business executive and alleged fraudster.

He is a cofounder and former CEO of Celsius Network, a bankrupt cryptocurrency lending platform.

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.

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.

Mashinsky was an early developer of voice over Internet Protocol (VOIP).

In the early 1990s, Mashinsky founded VoiceSmart, one of the first firms to offer telecommunications switches to handle ordinary voice as well as Voice over IP call routing.

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.

Mashinsky founded GroundLink in 2004 as a service to book an on-demand limousine and car services from a computer or smartphone.

He was also the founder of Q-Wireless, which later became part of Transit Wireless.

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 a complimentary in-flight WiFi pass to travelers who booked a GroundLink limousine while aboard their US flight.

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.

From 2014 to 2015, Mashinsky served as CEO of Novatel.

Mashinsky is the defendant in a civil lawsuit brought in January 2023 by the Attorney General of New York, who accuses him of committing securities fraud during his time as Celsius CEO.

On July 13, 2023, the Securities and Exchange Commission charged Mashinsky and Celsius with violating federal security laws.

On the same day, he was indicted and arrested by federal authorities in the Southern District of New York for alleged fraud and market manipulation.

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.
