Noesis Infotech · Thane, Maharashtra · India
We design and ship web platforms, mobile apps, cloud infrastructure and AI automation for companies that have outgrown off-the-shelf software — and we run WhatsApp Business API at production scale through our own products.
// 01 — capabilities
Not a list of everything we could theoretically attempt. This is the work we do week in, week out — with our own products as the proving ground.
Product-grade web platforms
Dashboards, portals, marketplaces and custom SaaS built on Next.js, React and TypeScript — typed end to end, server-rendered where it matters, and fast on a mid-range Android phone, not just on your laptop.
Apps that feel native and actually ship
iOS and Android from one well-factored codebase, with native modules where performance demands them. Offline-first data, push, deep links, payments and store submission handled end to end.
Infrastructure that survives your growth curve
We design for the traffic you will have, not the traffic you have. Containerised services, queues and workers, read replicas, autoscaling, structured logs and dashboards — with a cost model you can read on one page.
Agents and pipelines that absorb the repetitive work
Document extraction, retrieval-augmented answering, classification and multi-step agents wired into the systems you already run. Human-in-the-loop by default, evaluated against your real data, with guardrails and an audit trail.
WhatsApp as a real business channel
Official Meta Cloud API onboarding, number and display-name verification, template strategy that gets approved, campaign delivery, chatbots and two-way CRM sync. We build on this stack every day — and we sell it too.
// 02 — our products
Two WhatsApp Business API products, built and operated by us, serving businesses in India and beyond. Different commercial models, same engineering team behind them.

The full platform
Bulk campaigns, AI chatbots and automations on your own WhatsApp Business number — including coexistence mode, so your team keeps using the regular WhatsApp app on the very same number.

Pay per message
No monthly fee and no setup cost. Buy credits, run WhatsApp campaigns from your own business number, and pay only for what you actually send. Utility messages from ₹0.20.
Not sure which fits? Tell us your volume and we will point you at the cheaper one — even when that is the one we earn less from.
// 03 — how we work
The failure mode of software projects is not bad code. It is a long quiet stretch followed by a surprise. Our process exists to make that impossible.
We map the problem, the constraints and the blast radius before writing code. You get a written scope with testable acceptance criteria — not a vague estimate.
Data model, contracts and interfaces first. Decisions get recorded, so the third developer to touch this understands why it was built that way.
Working software every week, on a URL you can open on your phone. You steer while it is still cheap to steer.
Deployment, monitoring and handover docs. We stay on through the first stretch and leave you something you can run without us.
// 04 — the firm
Greek — understanding reached through intellect. We picked the name because the hard part of this work was never the typing.
Noesis Infotech is a proprietorship firm based in Thane, Maharashtra. We are a small, senior team that takes a business problem, argues about it properly, and then builds the thing — web, mobile, cloud or AI — and keeps it running.
We are not an agency with an account layer. The people you talk to are the people writing the code.
From the Postgres schema to the Play Store listing to the web server config — one team, no hand-off gaps to fall through.
WhatsBizAPI and WABAPI are ours, in production, with real customers. The integration you are buying is the one we run.
No junior churn, no learning on your budget. Fewer people, further along.
Specs, decision records and handover docs — so knowledge does not walk out the door with a contractor.
// 05 — straight answers
We build custom software: web platforms, iOS and Android apps, scalable cloud applications, and AI automations. We also provide WhatsApp Business API services — onboarding, template strategy, campaigns, chatbots and CRM integration — and we operate two WhatsApp API products of our own, WhatsBizAPI and WABAPI.
Our office is at FB 164, High Street Corporate Center, Kapurbawdi, Thane, Maharashtra 400607, India. We work with clients across India and internationally; most collaboration is remote, with overlap hours agreed up front.
Yes, and it is a large share of our work. We start with a read-only audit: architecture, dependency and security state, test coverage, and the riskiest areas. You get a written assessment and a prioritised plan before anyone changes a line.
WhatsBizAPI is the full platform on a subscription — campaigns, AI chatbots, a multi-agent inbox and coexistence mode, which lets you keep using the normal WhatsApp app on the same number. WABAPI is pay-per-message with credits and no monthly fee, with utility messages from ₹0.20 — better suited to lower or bursty volumes.
Three shapes: a fixed-scope project against written acceptance criteria; a monthly retainer for continuous product work; or a dedicated pod of engineers embedded with your team. We will tell you which one fits after the first conversation.
Send us a message on WhatsApp at +91 81699 52766 or email support@noesistech.com with a paragraph about the problem. The first call is a scoping conversation, not a sales pitch, and it is free.
// 06 — contact
Fill this in and it composes a WhatsApp message for you — no inbox, no auto-responder, no waiting. Fittingly, given what we do for a living.
