Welzin

Full-stack AI & data firm

We build AI and data systems that move the number.

Welzin is a full-stack AI and data firm: data science, predictive analytics, AI engineering, MLOps/AIOps, and the product engineering to keep it running.

Startup or enterprise, we move your numbers - revenue, risk, uptime, margin. Senior engineers, in production from day one.

  • Data Science & ML

    Predictive analytics, Data Engineering, Statistical and ML modeling that turns messy data into decisions.

  • AI Engineering

    Generative AI and AI agent development - RAG, Tool use and Agents grounded with evaluation and guardrails.

  • MLOps & Operations

    Scale on Kubernetes with DevOps/MLOps services that keep systems healthy in production: pipelines, drift monitoring & retraining.

Proof from production.

Production systems for teams measured on the result. Each engagement starts with one metric; here is how far it moved once the system shipped.

What we do

Our services.

Everything a production AI system needs - built, shipped, and operated by the same senior engineers.

Numbers we answer for.

What it looks like when a senior team stays accountable - shipped systems, returning clients, uptime, and speed to first result.

Why teams choose Welzin.

The team you meet on the first call is the team that ships.

Discovery to a measured result.

From first conversation to a system you own in production - most clients see a measured result inside six weeks.

  1. 01

    Scope

    A senior engineer - not a salesperson - maps your metric, data, and constraints, then scopes the smallest build that can move the number.

  2. 02

    Ship

    We build in your environment and reach production early - evaluated pipelines, grounded GenAI, agents with guardrails - with you in the loop every week.

  3. 03

    Run & measure

    We operate what we shipped, report against the metric we agreed, and hand over a system your team can run without us.

Client results, in their words

Fraud losses fell 41% in the first quarter without adding review headcount. The engineers who scoped the model were the ones on call at launch.
Daniel BrooksVP Risk, Northbeam Pay (US fintech)
Forecast error is down 32% across 1,400 SKUs, and their pod still reviews drift with us monthly. The first vendor that put the metric in the contract.
Priya HalloranHead of Data, Calder & Vine (UK retailer)
ETA accuracy went from 71% to 93% in eight weeks. No discovery theatre - a senior engineer was in our warehouse data by day three.
Faisal MansourCOO, Gulfline Logistics (UAE)
They rebuilt our inference stack before Series A diligence - serving costs down 47%, eval pass rates doubled, and the runbooks were ours from day one.
Arjun MalhotraCEO, Neuraxis Labs (India deep-tech AI)

Answers to questions about

What does Welzin actually do?

We are a full-stack AI & data firm across five disciplines: data science, predictive analytics, AI engineering (RAG, copilots, agents), MLOps/AIOps, and the product engineering that ships it all. One senior team owns the path from the first model to a system running in production - not slideware.

What kinds of problems do you take on?

Anything where data should be driving a decision and is not yet: forecasting, risk and fraud scoring, churn, document and workflow automation, copilots and agents, and the data platforms underneath them. If it touches a number you care about, it is in scope.

Tell us the number you want to move.

A metric that’s stuck, a system that needs rescuing, or a build you want scoped - a senior engineer reads every note.
