What's with the name?
...and a bit of history

"A hypothetical particle that always travels faster than the speed of light."

San Diego based Tachyon Networks was founded in 1997 by Dr. John E Koehler, a native of Olympia, WA (and Star Trek fan).  He was a 1963 summa cum laude graduate of Yale University, where he also received a doctorate in economics.

Recruited to work in the economics department of the Rand Corporation, he worked on policy analyses in national and international security before becoming Assistant Director of the Congressional Budget Office, establishing its national security and international affairs division.

From 1978 to 1982, Dr. Koehler served as CIA deputy director and director of the intelligence community staff during which time he oversaw procurement of advanced satellite communications and computing systems for the federal government.  Before founding Tachyon, he served as Chief Operating Officer of Titan Corporation, maker of satellite equipment for commercial and government customers. 

Tachyon Networks was the first company to offer two-way, high-speed Internet access over satellite. Transporters were to be next.  Declining health forced him to resign as president and chief executive in December of 2000. 

Dr. Koehler died of cancer on the 14th of December 2001 at his home in Carlsbad, CA.  Our continuing mission at Tachyon honours Dr. Koehler's legacy.

Our Team


Peter Carides

President & Chief Executive Officer

Peter was born in South Africa and spent his early years in Johannesburg and Lourenço Marques, Moçambique. As a teenager, Peter revelled in outdoor sports.


Through a bursary programme at Standard Telephones & Cables, Peter was able to secure an apprenticeship whilst studying electrical engineering. His first experience was to repair long-range microwave communications systems whilst camping in the bushveld amongst Africa’s then abundant wildlife. Only later did Peter realize how useful those skills would be for urban jungles. After his engineering education, Peter served in the South African Marine Corps’ elite Amphibious Boat Squadron during the Angolan war..

After his military service, Peter relocated to the (then) British Colony of Hong Kong to take advantage of the cellular communications boom. Whilst there, his lifelong passion for rugby and skydiving engendered invitations to play for the national squad and skydiving with the Hong Kong Formation Skydiving team. At the World Air Games held in Turkey in September 1997, the skydiving team showed up expecting to represent Hong Kong. However, thanks to a technicality of geopolitics, they were politely directed to the China tent. Search: “midnight july 1 1997”.

While in Hong Kong, Peter was recruited to operate a Qualcomm spin-off called Boatracs, providing satellite communications for the commercial maritime and oil exploration industries. Initially based in Amsterdam, Peter later relocated to San Diego to serve as Chief Operating Officer. After Boatracs, Peter moved to France to join Equant, operator of the world’s largest data network. France Telecom acquired Equant so, after four enjoyable years in Paris, Peter, sadly, returned to San Diego.


Peter has been with Tachyon the past 18 years collaborating with many talented colleagues to develop advanced C5 solutions. An avid pilot, photographer, and rower, Peter enjoys San Diego with his two dogs and seeks to practice the languages he’s picked up over the years: Greek (his heritage), Dutch, Chinese and Spanish…mainly with restaurant staff and tourists.

David Inmon


In 2008 David founded Redhorse Corporation and served as CEO through 2021. He was actively involved in all areas of the business, with a focus on strategic direction of the company. He currently serves as Chairman of the Board of Directors.  Before founding Redhorse, he was recalled to active duty in the Marine Corps in support of Operation Iraqi Freedom. For a year, David ran Besmaya Range Complex, an 85-square-mile live-fire training base in central Iraq. He led the effort train more than 4,000 Iraqi soldiers and established or managed four separate training programs during his tour. He was directly responsible for the supervision and safety of more than 150 military and contractor personnel and was awarded the Bronze Star Medal for his service in Iraq. He retired at the rank of Colonel in 2013 after 32 years of active and reserve service. 

Prior to returning to active duty, David was a partner in a boutique investment banking firm, where he helped small businesses raise capital and make divestitures and acquisitions. Earlier, he worked for a technology start-up company as Vice President of International Sales. The company was acquired by Oracle, where David spent a year in the wireless application server group working with international wireless carriers. Previously, David spent 8 years with Ericsson, delivering wireless voice and data systems to local, state, and federal governments. He led a team that was awarded the largest public safety radio system contract in Hawaii state history. He began his professional career as an artillery officer in the U.S. Marine Corps, spending 4 years on active duty before he joined the Marine Corps Reserve. He began his Marine Corps career at the Marine Corps Recruit Depot, San Diego, in the summer of 1981, where he was Series Honorman and meritoriously promoted to Private First Class. 

He holds a B.S. in Mathematics from the University of Oklahoma and a Masters in Business Administration from Arizona State University.


David Sadler

Chief Operating Officer

David Sadler is Tachyon Network’s COO. At a small company, this means he’s responsible for keeping customers and partners happy, scaling operations, and mowing the lawn.

David was born in southeast Asia and raised by his Vietnamese mother and American stepfather. Despite growing up an Air Force brat, David decided to join the Navy. That cross cultural exposure (East/West, Navy/Air Force) and other experiences gave him an appreciation for how varied the world is and its complexity. After eight years in the Navy, David hung up his Lieutenant bars and entered the business world. With his rank frozen in time, this has resulted in Peter regularly referring to him as “The Young Lieutenant”. If only that entire moniker was true.

Being equal parts left brain and right brain (a blessing and a curse), David likes varied challenges, resulting in his gaining experience in analytical disciplines such as strategic sourcing and supply chain, then counterbalancing that with roles in software development and marketing. Having worked with talented people in both large organizations (IBM, SAIC, Jacobs Engineering), and small (R3 Strategic Support Group, Cardinal Point Captains, Training Resources Limited), David has learned that with ingenuity, creativity, and effort, it is possible to solve difficult problems even, on occasion, fitting a round peg into a square hole.

A 1989 graduate of the U.S. Naval Academy, David was selected as a Cox Scholar and studied in France before his commissioning in the naval service. He holds a Master of Business Administration from the University of San Diego.
