MODULE

Setu eKYC

Digital client onboarding — Aadhaar-based eKYC, PAN verification, liveness checks and CKYC registry fetch, wired into your journey.

MODULE

Setu Re-KYC

Periodic KYC refresh on autopilot — scheduled journeys, reminders, document refresh and registry sync for brokers and NBFCs.

OCR

Setu OCR

Rust-powered document intelligence — PAN cards, Aadhaar, cheques and bank statements extracted to clean, validated JSON in milliseconds.

BOTS

Automations

Back-office bots that never sleep — reconciliations, regulatory report prep, file drops and data pipelines across your stack.

API

Bank Integrations

Production integrations with leading Indian banks — payments, virtual accounts, ASBA blocks and statement feeds on live API suites.

Superior, Modern Tech

Rust cores. React cockpits. Edge deploys.

Every SetuLab product runs on a superior, modern stack —Rust backends for deterministic, memory-safe speed under market-hours load, React and Astro front ends teams actually enjoy using, deployed to the edge for latency that feels local everywhere in India.

How We Engage

Three steps from hello to production

01

Scope

A working session on your problem — we map the product, the rails and the regulatory edges, then propose a fixed, honest scope.

02

Build

A senior, founder-led team ships in weekly increments — Rust and React, demos every Friday, no surprise rewrites.

03

Run

We deploy to the edge, wire up monitoring and stay on — operating, integrating and iterating as your volumes grow.

FAQ

Questions, answered

What is SetuLab?

SetuLab is a fintech product studio and holding company. We build and operate our own products — like BidFlow, an IPO application and form-printing platform for brokers — and we engineer eKYC journeys, back-office automations, bank API integrations and full platforms for financial-services clients.

Do you take client projects?

Yes. Alongside our own products we take on select client engagements — product engineering, platform and website builds (we designed and built trustnetsecure.com for TrustNet Secure), and fintech integration work.

Which banking rails do you integrate with?

We build on the API suites of leading Indian private banks — covering payments, virtual accounts, ASBA blocks and statement feeds — and we add rails as client roadmaps demand.

What does your eKYC and re-KYC work cover?

Digital onboarding journeys built on Aadhaar-based eKYC, PAN verification, liveness checks and CKYC registry fetches — plus scheduled re-KYC flows with automatic reminders, document refresh and registry sync for brokers and NBFCs.

Do you offer OCR for PAN cards and bank statements?

Yes. Setu OCR is our Rust-powered document-intelligence engine — it extracts PAN cards, Aadhaar, cheques and bank statements into clean, validated JSON in milliseconds, and plugs into eKYC journeys, loan-processing flows and back-office automations.

What is your technology stack?

Rust for backend cores where determinism and speed matter, React and Astro on the front end, and edge-first cloud deployment. Small, senior, founder-led teams ship every project.
