Sand Technologies builds the intelligent platforms behind critical infrastructure: water, healthcare, telecommunications, energy, for enterprises and governments worldwide. Our AI systems help manage London's water supply and power digital health platforms serving tens of millions of people. We build what matters to shift perception. Symmetri is the platform underneath that work. It integrates heterogeneous operational data, models the entities and relationships of an entire domain, and lets operators of critical infrastructure understand the state of their world, reason about it, and act. It runs in multi-tenant cloud, in single-tenant customer environments, on premises, and in fully air-gapped installations at ministry and utility level. Around fifty environments today.
