Building a space-based laser communications network in Medium Earth Orbit to replace undersea fiber cables for intercontinental data transit Endeavor Optical Networks was founded in 2026. The company is led by Charlie Horowitz. Based in Los Angeles, California, United States. Team size: 11-50. Total funding raised: $10.75M. Latest round: Seed. Key investors include General Catalyst, Andreessen Horowitz (a16z), Main Object, XYZ Venture Capital, Upfront Ventures.

Founded: 2026
Headquarters: Los Angeles, California, United States
Team size: 11-50
Total funding: $10.75M

Value proposition

Replace vulnerable undersea fiber cables with a dedicated, secure, space-based laser network that delivers fiber-level throughput (2.4+ Tbps per link) across oceans in months instead of years, at 1/10th the cost per bit

Products and solutions

EON Data Relay — dedicated point-to-point multi-Tbps data transfer via free-space laser optics through MEO satellites, Intercontinental Long-Haul routes, Path Redundancy (backup for subsea cables), Intra-Region Replication, New Region Bootstrapping

Unique value

First commercial space laser network targeting 2.4 Tbps per link (10x+ current demonstrated space-to-ground laser speeds), using MEO bent-pipe architecture with off-the-shelf satellite buses, deployable in months vs 5-7 years for subsea cables

Target customer

Hyperscalers (cloud providers), AI labs, content delivery networks (CDNs), telecom operators, enterprises with large intercontinental data transfer needs, sovereign governments

Industries served

Cloud Computing, AI/ML, Telecommunications, Financial Services, Government/Defense, Enterprise Data Infrastructure

Technology advantage

Free-space laser optical communications in MEO (Medium Earth Orbit) with bent-pipe architecture; targeting 2.4 Tbps per link (vs 2.5 Gbps demonstrated by competitors); proprietary atmospheric distortion compensation; off-the-shelf satellite buses from Apex Space reducing cost and timeline; ~20 satellite constellation (vs 5,000+ for competitors like Blue Origin TeraWave)

How they differentiate

Smaller, faster-to-deploy constellation (~20 satellites vs 5,048 for Blue Origin TeraWave); MEO bent-pipe architecture (no inter-satellite links needed); dedicated point-to-point capacity (not shared); targets 2.4 Tbps per link from day one; can bring capacity online in months vs years for subsea cables; 1/10th the cost per bit vs traditional long-haul capacity

Main competitors

Blue Origin TeraWave (5,048-satellite network targeting 6 Tbps), Traditional subsea fiber cable providers (SubCom, Alcatel Submarine Networks), Other space laser comms companies (York Space Systems, Kepler Communications, Cailabs)

Key partnerships

Apex Space (satellite bus supplier — Horowitz's former employer), Ian Cinnamon (Apex CEO, personal investor)

Major milestones

Founded May 2026, Emerged from stealth August 2026 with $10.75M seed round, Plans to launch demo satellite by end of 2027 targeting 800+ Gbps (potentially 1 Tbps) optical downlink — highest ever, Building optics lab and hiring engineering team

Market positioning

Early-stage disruptor in the space-based data transit market, positioning as a faster, cheaper, more secure alternative to subsea fiber cables for hyperscalers and AI labs, with a more pragmatic and achievable constellation size than competitors

Geographic focus

Global — initial focus on underserved/long-haul intercontinental routes (e.g., France to Australia, Africa to South America, transatlantic, transpacific)
