About
QSTM Ai Systems Private LimitedAI you own outright, not AI you rent by the token.
QSTM Ai Systems Private Limited is the legal entity behind the CustomAi.in brand: a Chennai-based bespoke AI studio building sovereign, client-owned AI systems across three products — Salient 1.0, Umpire and Verity.
Salient 1.0 runs on the client’s own weights, fine-tuned on their own corpus, with no OpenAI, Anthropic or Google in the loop and no outbound calls at runtime. That distinction — owned, not rented — runs through everything we build.
Salient 1.0 reasons, Umpire checks every action before it happens, and Verity puts both to work across the apps a company already runs.
Sovereign AI. Governed. Custom-orchestrated.
One line, one word per product: Sovereign is Salient 1.0, Governed is Umpire, Custom-orchestrated is Verity.
Brand pillars
| Pillar | What it means in practice |
|---|---|
| Ownership | Own weights, escrowed or perpetually licensed — never a subscription to someone else’s model. |
| Sovereignty | On-prem or in-country deployment; regulated data never leaves the client’s tenancy. |
| Evidence | Cites sources, states when evidence is missing — no confident fabrication. |
| Governance | Guardrails, human-in-the-loop escalation, and confirmation before irreversible actions. |
| Proof before purchase | Performance benchmarked on client-designed, rerunnable tests before commercial terms are agreed. |
