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.

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.

01 / 05

  • 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.

02 / 05

  • 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.

AI Engineering

Production Generative AI and autonomous agents - RAG, copilots, and tool-using workflows, grounded with evaluation and guardrails.

03 / 05

  • RAG & knowledge assistantsAssistants grounded in your documents, with retrieval and citations you control.
  • Copilots & autonomous agentsTool-using agents that plan and complete real workflows.
  • LLM fine-tuningTune and adapt models to your domain, voice, and tasks.
  • Evaluation & guardrailsMeasured quality and safety checks before anything ships.
  • Document & workflow automationAutomate document-heavy and repetitive workflows end to end.
  • Vector & semantic searchFast, meaning-aware search across your knowledge and data.

MLOps / AIOps

Keep models and AI systems healthy in production - automated pipelines, monitoring, and the observability that catches drift before your users do.

04 / 05

  • CI/CD for modelsAutomated pipelines to train, test, and ship models safely.
  • Feature storesA single, governed source of features for training and serving.
  • Drift & quality monitoringCatch model decay and data drift before your users feel it.
  • Model registry & governanceVersioned, audited models with clear ownership and approvals.
  • Scalable inferenceServe models reliably at the latency and scale you need.
  • Cost & incident observabilityFull visibility into spend, health, and incidents in production.

Engineering Development

Full-stack product engineering around your AI - APIs, web and mobile apps, cloud infrastructure, and the data platforms that ship and scale it.

05 / 05

  • Web & mobile applicationsPolished, production web and mobile apps built around your AI.
  • API & backend engineeringRobust APIs and services that scale with your product.
  • Cloud & DevOpsCloud infrastructure and automation built for reliability.
  • Data platforms & lakehousePipelines, warehouses, and lakehouse foundations that feed it all.
  • System architectureArchitecture that holds up as data and traffic grow.
  • Platform modernizationModernize legacy systems without stalling the roadmap.
