RainDB
Ask the database without opening the rows
Run queries on encrypted tables. Start on one U100; add cards when concurrency grows on your host.
Platform →Use the data without opening it.
Every institution hits the same wall: analytics and AI only work after decryption. Umbra removes that wall. RainDB and ZChat run on ciphertext, sized from one evaluation card to finished N4 / N8 nodes.
Two workloads. Every sector.
ZChat
Private AI that never sees the prompt in the clear
Encrypted prompts and outputs end to end. Entry on 1–2 cards beside existing GPUs; reference pack 6 × U100 + 2 × NVIDIA.
Platform →Who this is for
Pick the world you recognise. Each path maps the same packs to accreditation, privacy, and sovereignty constraints.
