Poseira (formerly Plastic-i) uses satellite imagery and AI models to transform complex water signals into auditable, continuous insights for decision makers navigating water-based ecosystems.

Our capabilities extend to a growing set of applications, including plastic debris tracking, harmful algal bloom prediction, blue carbon monitoring, aquaculture oversight, and insurance risk modelling for water-based hazards - each requiring continuous observation over infrequent, in-situ checks.

We serve clean-up operators and NGOs prioritising intervention efforts, water utilities monitoring catchments,  and government bodies overseeing water quality and licensing, blue carbon project developers verifying restoration outcomes, and aquaculture operators managing site risk. We also support insurers and brokers with objective triggers and indices for pricing underserved water perils.

We are a UK-based, 2x Earthshot Prize-nominated, Lloyd's Lab-incubated company. Follow Poseira for updates on our work, or visit poseira.com to get in touch.
