The full AI & data stack, one senior team

Five disciplines, one accountable team - from the first model to autonomous agents and the platforms that run them. Pick a starting point; we take it from discovery to a measured result.

AI development services are the design, build, and operation of production machine-learning and generative-AI systems on top of a company's own data. Welzin delivers them end to end across five disciplines: data science that turns raw data into decisions, predictive analytics, AI engineering (retrieval-augmented generation, copilots, and autonomous agents), MLOps and AIOps that keep models reliable in production, and the product engineering that ships the resulting interface to users. One senior pod owns the path from the first model to a monitored system running in production, with no hand-offs to juniors along the way, and every engagement is scoped to a single business metric the work is accountable for moving. Welzin is based in Chandigarh, India, and works remotely with startups, SMEs, and enterprises across the United States, United Kingdom, United Arab Emirates, and India, handing over systems the client's own engineering team can run and extend without Welzin in the loop.

Data Science

We turn messy, real-world data into models and insight you can act on - rigorous, validated, and tied to a business question that matters.

  • Exploratory data analysisProfile and visualize raw data to surface patterns, gaps, and the questions worth modeling.
  • Statistical & ML modelingRigorous, validated models that turn the signal in your data into reliable predictions.
  • Experiment design & A/B testingDesigned experiments that measure real causal impact, not noise.
  • Customer & revenue analyticsSegmentation, LTV, and cohort analysis that explain what actually moves the business.
  • Feature engineeringEngineered, reusable features that lift model accuracy and stability.
  • Data storytellingClear narratives and dashboards that turn analysis into decisions.

Predictive Analytics

Forecast what happens next - demand, churn, risk, revenue - and wire those predictions straight into the decisions that depend on them.

  • Demand & revenue forecastingForecasts that plug straight into planning, inventory, and budgets.
  • Churn & propensity modelsSpot who will leave or convert in time to act on it.
  • Risk & fraud scoringReal-time scoring that flags risk before it costs you.
  • Recommendation enginesPersonalized recommendations that lift engagement and basket size.
  • Time-series & anomaly detectionCatch trends and outliers across your metrics as they happen.
  • Decision intelligenceWire predictions straight into the decisions that depend on them.

Services, answered

What AI development services does Welzin offer?

Welzin works across five disciplines: data science, predictive analytics, AI engineering (RAG, copilots, and agents), MLOps/AIOps, and the product engineering that ships them. One senior pod owns the path from the first model to a system running in production.

Does Welzin work with startups or with enterprises?

Both. Welzin builds for startups scaling on AI, SMEs automating with data, and enterprises taking GenAI to production. The engagement is scoped to the metric that matters, so the team size and depth match the problem rather than a fixed package.

Where does Welzin operate?

Welzin is based in Chandigarh, India, and works remotely with clients across the United States, United Kingdom, United Arab Emirates, and India.

How is a Welzin engagement scoped and priced?

Every engagement opens with a short scoping step where a senior pod maps the metric, the data, and the constraints, then scopes the smallest build that moves the number. Pricing is tied to that outcome and milestone rather than open-ended hours.

What is the difference between AI engineering and MLOps at Welzin?

AI engineering builds the system: production RAG, copilots, and autonomous agents grounded with evaluation and guardrails. MLOps/AIOps keeps it running: CI/CD for models, feature stores, drift monitoring, a model registry, and scalable inference.

Who does the actual work on an engagement?

Small pods of senior engineers, with no hand-offs to juniors. The engineers who scope your system are the ones who build and operate it, and the work stays visible the whole way.
