Full-stack AI & data firm
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.
DevOps/MLOps & Operations
Scale on Kubernetes with DevOps/MLOps services that keep systems healthy in production: pipelines, drift monitoring & retraining.
Production systems for teams measured on the result. Each engagement starts with one metric; here is how far it moved once the system shipped.
Everything a production AI system needs - built, shipped, and operated by the same senior engineers.
We turn messy, real-world data into models and insight you can act on - rigorous, validated, and tied to a business question that matters.
Forecast demand, churn, risk, and revenue - wired into the decisions they drive.
Production GenAI and agents, grounded with evaluation and guardrails.
Pipelines, monitoring, and observability that catch drift before your users do.
APIs, apps, cloud, and data platforms - the product engineering around your AI.
What it looks like when a senior team stays accountable - shipped systems, returning clients, uptime, and speed to first result.

The team you meet on the first call is the team that ships.
From first conversation to a system you own in production - most clients see a measured result inside six weeks.
Talk to a senior engineerA senior engineer - not a salesperson - maps your metric, data, and constraints, then scopes the smallest build that can move the number.
We build in your environment and reach production early - evaluated pipelines, grounded GenAI, agents with guardrails - with you in the loop every week.
We operate what we shipped, report against the metric we agreed, and hand over a system your team can run without us.
A firm that ships products is a firm you can check up on - here's what we run ourselves, in production, under our own name.

“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.”
“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.”
“ETA accuracy went from 71% to 93% in eight weeks. No discovery theatre - a senior engineer was in our warehouse data by day three.”
“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.”
What running AI in production teaches us each week - written by the engineers doing the work, for the people measured on it.
AI Models
Anthropic's most capable model is the first from its Mythos tier, a rung above Opus. The positioning, the specs that matter, the benchmarks, and the practitioner's rule for when its 2x price is actually worth paying.
AI Tooling
Karpathy's LLM wiki reverses the second brain: the model builds and maintains it, you only add sources. The three-layer architecture, the ingest-query-lint loop, why it beats RAG at personal scale, and the advanced moves that make it production-grade.
GenAI & Agents
Large Language Models (LLMs) like GPT-4, LLaMA, and Claude now power critical real-world applications - from customer support bots that might accidentally...

GenAI & Agents
Like explaining a project to a friend, you give background not 200 pages of docs. AI models face the same challenge with context length.
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.
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.
Welzin is based in Chandigarh, India, and works remotely with startups and enterprises across the United States, United Kingdom, United Arab Emirates, and India.
Yes. Welzin builds production GenAI and retrieval systems and structures its own and clients' content so it is accurate, well-marked-up, and citable by AI answer engines like ChatGPT, Perplexity, and Google's AI surfaces.
A metric that’s stuck, a system that needs rescuing, or a build you want scoped - a senior engineer reads every note.
