Gregory Thane Wyler is an American tech entrepreneur, engineer, and inventor. He was the founder and executive chairman of OneWeb^[1] and the founder of O3b Networks.

Wyler spent four years developing telecommunications in Africa in rural locations. In 2003,^[2] he built a local team and connected over 200 schools to the Internet, providing the first 3G and fiber connections to residences on the continent.^[3] In 2006 his company Terracom acquired 99% control of Rwandatel,^[4] although the government of Rwanda then bought Rwandtel back in 2007.^[5][6]

In 2007, he founded O3b Networks, Ltd.^[1] The idea for creating a medium Earth orbit satellite network to provide voice and data communications to remote locations was first conceived while working on a project to provide a nationwide telephone service in rural Rwanda, attempting to wire the post-war and economically shattered country.^[7] O3b has launched 12 satellites.

In 2012,^[8] Wyler founded OneWeb with the mission of "enabling Internet access for everyone".^[9]

On 1 August 2016, satellite operator SES S.A. completed the acquisition of O3b Networks.^[10]

In March 2020. OneWeb entered Chapter 11 bankruptcy after failing to raise enough capital to complete the build and deployment of its satellite constellation.^[11] OneWeb exited bankruptcy with new investment, but Wyler was no longer involved with the company.^[12]

Wyler founded satellite communications company E-Space in 2022, to create a network of satellites providing services targeting governments and businesses.^[13][14][15]

In January 2026, newly unsealed Epstein files showed that Wyler had a business and social relationship with sex offender Jeffrey Epstein. Wyler didn't deny the accuracy of the files but said his interactions with Epstein “at all times were professional,” and that they “did discuss investing, but no investment ever occurred. To state this more broadly, I never accepted any offer or request he made to invest or support any company I was associated with.”^[16]

The documents show Wyler corresponding and visiting Epstein multiple times, and Epstein advising Wyler on fundraising for OneWeb.^[17][18] The files also show Wyler attending a meeting with Epstein and Richard Branson on Branson's Necker Island. Epstein brought three of his victims to the meeting. ^[19]

In 2015, Wyler received the Arthur C. Clarke award for Innovation^[20] and the 2B AHEAD Innovators Award.^[21] In 2017, Wyler was voted the Top Rising Star in Wireless by Fierce Wireless^[22] and later that year, The Most Powerful Person in Telecommunications.^[23] In 2018, he was inducted into the French Legion of Honour.^[24]
