We are facing a global crisis where bacterial infections are becoming increasingly deadly due to antibiotic resistance. The health and economic consequences are staggering, with bacterial disease predicted to be the #1 cause of death by 2050. Alternatives are urgently needed, but nature already has its solution: phages, the natural predators of bacteria. At Phagos, we are bringing back phage technology by combining advances in microbiology with cutting-edge artificial intelligence. Our patented technology makes large-scale, customized phage-based veterinary medicines possible for the first time. And soon well universalize the technology for human health too. Our mission is to end bacterial disease.

At Odin Space, we’re transforming space safety and risk management by delivering the only intelligence on lethal, non-trackable debris. This sub-centimetre debris is capable of causing significant damage to spacecraft, but too small for conventional tracking systems. By pairing real-time debris insight with targeted insurance solutions, we make on-orbit coverage significantly more affordable and effective for satellite operators. Odin’s Nano Sensors are proprietary on-orbit impact detectors that provide instant failure attribution and collision diagnostics, giving spacecraft operators clarity when something goes wrong in space. Combined with our Scout Satellites, which monitor debris risk across key orbital environments, Odin delivers a new layer of real-world intelligence that improves decision-making, strengthens resilience, and unlocks more affordable, targeted on-orbit insurance. Our customers can now access a new collision-focused insurance product underwritten with Lloyd’s of London that is ~100× more affordable than traditional space insurance — lowering barriers for spacecraft operators and accelerating innovation in space. What we do: • Advance on-orbit safety with real-time, high-precision debris detection • Deliver actionable collision diagnostics and failure attribution powered by our proprietary Nano Sensors • Provide a new class of on-orbit insurance that’s affordable, streamlined, and designed for the realities of today’s rapidly growing space ecosystem What sets us apart: • Industry-leading debris detection that identifies threats standard systems miss • Data-driven insights enabling faster, smarter decisions for operators and partners • Innovative insurance solutions that align risk with real-time observability We’re building a safer future in orbit — and inviting partners, customers, and talent who want to be part of the next wave of space innovation.
