ZipLogic
ZionChain Pte. Ltd. builds a PCIe accelerator card that runs AI inference and database queries on encrypted data, without ever decrypting it.
The decryption gap is the moment useful data must be decrypted to be computed on. Umbra closes it at production speed. We sell to institutional and government buyers: defence, finance, infrastructure, sovereign AI: and we do not operate customer data.
What we ship
Umbra U100 is the card: 40M encrypted operations per second, measured. N4 and N8 are configured nodes, with throughput labelled estimated until end-to-end node measurement completes. RainDB and ZChat run on the same Umbra runtime. Anything built on a card runs unchanged on a node.
Where we work
Leadership
Gen Chia
Chief Executive Officer
Founded ZipLogic to close the decryption gap for institutions that cannot expose data to use it. Previously built an all-female esports organisation in a category that did not yet exist: the same problem as encrypted compute hardware.
Lennise Ng
Chief Operating Officer
Y Combinator alumna (W20). Co-founded Borong (formerly Dropee), scaling B2B commerce and SME financing across ASEAN. Runs ZipLogic operations: deployment readiness, organisational execution, and evaluation through to installed systems.
David Zheng
VP of Encryption
Leads the cryptographic programme and is named inventor on nine granted Umbra patents. Architecture notes, documentation, and a second reader sit around the inventor: the research function is not a single-person dependency.
Jim Zheng
VP of Product
Owns the Umbra product surface: RainDB, ZChat, the SDK, and the roadmap from card to workload.
Deborah Gouineau
VP of Marketing
Decade-plus brand and marketing leadership (Warner Hotels, Three UK). Positions ZipLogic for institutional buyers, not consumer noise.
Hazman Hassan
VP of Business Development
Builds institutional partnerships and commercial programmes across Southeast Asia: architect by training, operator by practice.
