70% lower project costs

Zero ramp-up time

AI agents supervised by senior leads

Lean methodology. No bloat.

Traditional ESNs sell you junior consultants at senior prices. q4o trains AI agents on lean methodology and pairs them with senior human leads. You get faster delivery, zero ramp-up time, and 70% lower project costs.

Key Expertise

Lean. Specialized. AI-first.

✦

Data Engineering

Pipelines, lakehouse architectures, real-time streaming. Our agents build production-grade data infrastructure using dbt, Spark, Airflow, and modern tooling.

✦

AI / ML Engineering

From fine-tuning LLMs to deploying inference pipelines. We ship models to production, not PowerPoint decks. MLOps, RAG, agents, evaluation.

✦

Full-Stack Development

Web apps, APIs, cloud infrastructure. Python, Rust, TypeScript. Our agents write code, our humans review it. Ship faster with leaner teams.

✦

AI Strategy & Lean Transformation

Where to apply AI for maximum ROI. We audit your workflows, identify waste, and deploy agents that eliminate it. Lean methodology, applied to AI adoption.

Our Process_

From your brief to deployed agents.

Define scope

You explain the project. We map it to lean work units.

Configure agents

We train and configure AI agents specific to your stack and domain.

Ship iteratively

Agents deliver. Senior leads review. You get production code, not slides.

Scale or stop

No lock-in. Scale agents up when it works, shut them down when done.

Frequently Asked Questions

Answers to the most common questions about the q4o model.

Are the AI agents fully autonomous?

No. Every agent is supervised by a senior human lead. AI handles the volume work (code generation, data pipeline scaffolding, testing, documentation), while humans handle architecture decisions, code review, and client communication.

How do you guarantee quality at 70% less?

Traditional ESNs bill for time, not output. Most junior consultant time goes to learning the stack, writing boilerplate, and sitting in meetings. Our AI agents eliminate that overhead. You pay for deliverables, not headcount.

What's the lean methodology angle?

Every project is broken down into value streams. We identify waste (waiting, context switching, rework) and configure agents to eliminate it. Short iterations, continuous delivery, no bloat.

Can I start with a small pilot?

Yes. Most clients start with a 1-month, 1-agent pilot on a contained scope. No long-term commitment required. If it works, scale. If not, stop.

What technologies do you cover?

Python, Rust, TypeScript, SQL, dbt, Spark, Airflow, Terraform, AWS/GCP/Azure, React, FastAPI, LangChain, and most modern data/AI stacks. Our agents are trained on your codebase and conventions.
