About
Enterprise AI, engineered end-to-end — in India.
Sigma Tech India is a Bengaluru AI engineering company that designs, trains and deploys production AI in-house. We never resell or white-label another vendor's model — every engine we ship is owned, auditable and reproducible, from consumer apps at scale to enterprise systems behind a VPC.
Philosophy
Built in-house — you pay only when it's live.
We start with a free on-site audit of your operations and target bottleneck, then propose a costed architecture and build it end-to-end. There is no reselling and no white-labelling — the same team that scopes the problem writes the code and stands behind the deployment. You pay only when the system is live and you are satisfied.
Engineering
Deterministic, auditable, DPDP-aligned.
For regulated industries, plausible is not enough. Our systems are deterministic — the same input produces the same output — so every decision can be reproduced and explained. We engineer for traceability and data minimisation, aligned with India's Digital Personal Data Protection (DPDP) Act, rather than bolting compliance on afterward.
Team & culture
A small team that owns the whole stack.
We are deliberately compact — hardware and silicon engineers, ML researchers and app builders who work across the whole stack rather than in handoff silos. That breadth is what lets one team take a problem from birth-detail privacy design to a shipped app on two stores, or from a data pipeline to a VPC-hosted engine.
What we hold to
Values that shape every build.
In-house, end-to-end
From data pipeline to deployed engine, every layer is built by our own team. No reselling, no white-labelling, no third-party black boxes.
Deterministic by default
The same input yields the same output. Systems are reproducible and their decisions can be explained — not merely plausible.
Auditable & DPDP-aligned
Engineering that regulated industries can trust: traceable decisions, data minimisation and alignment with India's DPDP Act.
Outcome-based
You pay only when the system is live and you are satisfied. Our incentive is a working deployment, not billable hours.
Meet the founder
Shubham Raj
Founder & CEO
An ex-Bosch hardware and silicon engineer with an MBA from NMIMS and IRDAI certification, Shubham founded Sigma Tech India on one conviction: enterprise AI should be engineered the way silicon is — deterministically, verifiably and end-to-end. As a serial founder, he has repeatedly taken products from first principles to live in the market.

Tell us the problem. We'll audit it, propose an architecture, and you pay only when it's live.
