Est. 2020 DPIIT Recognized Startup

Who We Are

A Team of Engineers & Product Builders

Founded in 2020 by Krishnendu & Kajal Karmakar, Zusta Autonetic Pvt. Ltd. is a full-stack software development agency headquartered in Kolkata, India. We started with a simple belief: most agencies over-sell and under-ship. We set out to be the opposite.

Today we've shipped 150+ production builds for 50+ clients across India, the US, UK, UAE, and Singapore — websites, iOS & Android apps, SaaS platforms, custom backend software, and AI integrations using Claude, GPT, and RAG pipelines. Every build comes with real architecture, real tests, full source ownership, and an honest ship date.

Our Mission

To build software that earns its keep — production-grade websites, apps, SaaS platforms, and AI integrations that ship on time, scale cleanly, and hand off without drama. We measure success by what makes it to production, not by pitch decks.

Our Vision

To be the software agency that founders recommend to other founders. An engineering team that talks to clients like peers, writes code like the person maintaining it next year is a friend, and treats every build as if our name is in the git log. Because it is.

Our Values

What Drives Us Every Day

Ship or Say So

If a deadline is slipping, you hear it from us before it does. No hiding bad news behind status emails. Every sprint ends with a working demo — or an honest reason why it didn't.

Code Quality First

Every PR gets reviewed. Every feature gets tested. We'd rather ship one clean feature than five half-working ones. Your future self (or future engineering team) will thank us.

No Vendor Lock-in

You own the code, the repo, the credentials, and the infrastructure. We give you the keys on day one. If you ever want to walk away, you can — we build for that.

Git-Level Transparency

You get commit access, CI/CD dashboards, and weekly demos from day one. You always know exactly where your project stands — down to the pull request.

Right Tool, Not Trendy Tool

We don't force Next.js on a brochure site or Laravel on a 10-user dashboard. We pick the stack that fits your project and your team — then defend that choice with real reasoning.

Founder Empathy

We've shipped our own products. We know runway pressure, investor demos, and the cost of shipping late. Your constraints are our constraints — we work inside them, not around them.

Our Team

Meet the Experts Behind the Magic

A diverse team of strategists, creatives, analysts, and technologists united by a passion for digital excellence.

Krishnendu Karmakar

Co-Founder & CEO

Full-stack engineer and product builder. Leads architecture, engineering hiring, and delivery. Writes code alongside the team — still reviews critical PRs himself.

Kajal Karmakar

Co-Founder & Creative Head

Leads UI/UX, design systems, and brand for every project we ship. Makes sure engineering-led products don't look engineering-led.
