EON Plans Laser Satellite Network to Replace Undersea Fiber
Endeavor Optical Networks (EON), a startup founded in May, emerged from stealth with $10.75 million in seed funding from General Catalyst and Andreessen Horowitz to build a network of laser-equipped satellites for high-capacity links between data centers. Co-founders Charlie Horowitz (CEO) and Tyler Pressler (CTO) say the company aims to deliver terabit-class space-to-ground optical links and intends an initial constellation of about 20 satellites to provide dedicated continent-to-continent connections and 24-hour coverage for early customers. EON will use the seed round to build an optics lab, hire engineers, perform ground tests and pursue a demo satellite launch targeted around the end of 2027 (expected downlink 800 Gbps–1 Tb). The startup is targeting hyperscalers, AI labs and underserved or expensive routes as customers while competing with larger proposals such as Blue Origin’s TeraWave.
The story describes a tech startup raising seed funding to pursue a potentially impactful alternative to undersea fiber for high-capacity intercontinental data transit; it could affect data-center connectivity, CDNs and hyperscaler routing on underserved routes, but the project is early-stage and technically challenging.

EON: Laser-based Space Links to Replace Subsea Cables
The article argues that subsea fiber — which carries roughly 95% of intercontinental data — is increasingly fragile and slow to expand, citing recent cable cuts and logistical limits of cable-laying. Endeavor Optical Networks (EON) proposes a space-based alternative: ground-to-satellite optical laser relays into Medium Earth Orbit (MEO) using a bent-pipe architecture to deliver multiple terabits per second between continents. The piece describes how cheaper commercial spacecraft, standardized components, and established supply chains now make high-throughput space links economically viable. EON targets hyperscalers, enterprises, and sovereigns, claiming capacity can be deployed in months and providing route-diverse intercontinental bandwidth that avoids the seabed.
Blue Origin proposes 50,000+ satellites as space data centers
Blue Origin filed documents with the U.S. Federal Communications Commission on March 19 seeking permission for “Project Sunrise,” a network of more than 50,000 satellites designed to perform advanced computation in orbit and offload energy- and water-intensive compute from terrestrial data centers. Blue Origin said it intends to use another proposed constellation, TeraWave, as a high-throughput communications backbone. The filing gave few technical details; TechCrunch notes similar plans from SpaceX (a proposed million-satellite data center), startup Starcloud (60,000 craft) and Google’s Project Suncatcher (demo spacecraft via Planet Labs). The article highlights major technical, economic and environmental challenges—cooling, radiation effects on chips, laser inter-satellite communications, launch costs and orbital congestion—and experts expect such projects to be realistic only in the 2030s.
Ex-SpaceX Engineers Raise $50M to Revolutionize Data Centers
Three former SpaceX engineers — Travis Brashears, Cameron Robinson and Serena Grown-Haeberli — founded Mesh Optical Technologies, a Los Angeles startup that raised $50 million in a Series A led by Thrive Capital. Mesh plans to mass-produce optical transceivers for data centers (targeting a production rate of 1,000 units per day within the year) to serve high-performance GPU clusters used for large AI model training and inference. The company aims to build supply chains outside China and qualify for bulk orders in 2027–2028. Mesh’s design removes a power-hungry component that its founders say could cut GPU-cluster power use by 3–5%. Investors frame the company as addressing interconnect bottlenecks and national-security risks tied to reliance on Chinese suppliers.
