About Welzin

A team of Forward Deployed Engineers built for the AI era

Startups scaling on AI, SMEs automating with data, enterprises taking GenAI to production - one senior pod deploys, builds, and runs it end to end.

Welzin is a full-stack AI and data firm that designs, builds, and operates production AI systems for startups and enterprises. Its work spans five disciplines: data science, predictive analytics, AI engineering with retrieval-augmented generation, copilots, and agents, MLOps and AIOps, and the product engineering that ships them. Welzin was founded by Aman Mundra, a machine-learning engineer with more than 10 years of experience at PayPal, Koch Industries, TransUnion, and HPE. The firm runs each engagement with one senior pod that owns the work from discovery through to a system in production, with no hand-offs to juniors, so the same engineers who scope a system are the ones who build and operate it. Welzin is based in Chandigarh, India, and works with clients across the United States, the United Kingdom, the United Arab Emirates, and India. Every engagement is accountable to the single metric it agrees to move.

Why production-first

A deck never moved a metric. Production does.

Most AI consulting stops at a slide deck or a proof of concept. Welzin’s founders are ML engineers from PayPal-scale production systems — authorization-rate, retry, and payment-routing models — where a model that isn’t live isn’t real.

So the firm is built the way those systems were: senior engineers only, no juniors, no hand-offs between strategy and shipping. We’re not a staffing shop — one compact pod owns each engagement from discovery to a monitored system in production, with data science, predictive analytics, AI engineering, MLOps, and product engineering working as one discipline, accountable to the metric we agreed to move.

Chandigarh-based and remote-first, we’ve shipped 40+ production systems for startups and enterprises across the US, UK, UAE, and India — and most clients return for the next build.

Our values

How we show up

Your metric, not our menu

Engagements start from the number you need to move, not a service catalog. The right answer is whatever moves it.

Senior pod, no juniors

Senior engineers only, with deep craft in data and AI. The size of the team is why the quality holds.

Production from day one

We ship early and iterate with evaluation and observability built in - a measured result beats a polished deck.

On the hook, in writing

Clear scope, honest trade-offs, clean systems handed back - and accountability for the outcome we signed up for.

What makes Welzin different from a typical AI consultancy?

Most AI consulting stops at a slide deck or a proof of concept. Welzin's founders are ML engineers from production systems, so the firm ships live systems accountable to a metric the team agreed to move, and stays on the problem until it is delivered.

Have a metric that has to move?

Bring the number and the constraint. A senior engineer - not a salesperson - will scope the path to a measured result in production.
