We build the AI
in 3-6 months.
You keep the infrastructure.

Westover Labs brings a decade of US big tech engineering to European companies. Custom AI infrastructure that keeps running after the engagement ends — better ROI than a five-year hire.

You need AI infrastructure.
You don't need a five-year hire to build it.

Most companies hire a staff engineer to build AI once, then keep them on indefinitely. There is a faster, cheaper, and more reliable model.

01

The Problem

Senior AI engineers command EUR 150–250k in total compensation. Companies hire them to solve a specific architectural problem, then keep them on to justify the headcount. The system never ships. The dependency never ends.

02

Our Approach

A focused 3–6 month engagement. We assess your stack, design the AI infrastructure you actually need, build it in production, document every decision, and train your team to own it.

03

What You Keep

Systems that keep running. Runbooks your team can follow. AI agents handling work that used to require constant human hours. Infrastructure that maintains itself. ROI that shows up in year one.


Three ways we work with you.

Each engagement is scoped to outcomes, not hours. You know what you are getting and when.

Most Popular

AI Transformation Sprint

Full AI infrastructure buildout tailored to your domain. Custom agent teams for your workflows, production ML pipelines, infrastructure as code, documentation, and team training for a clean handoff.

Ideal for companies that know they need AI but are not sure where to start — or have started and got stuck.

3-6 months / Fixed scope
Ongoing

Fractional CTO

Strategic technical leadership without full-time overhead. Architecture decisions, technical roadmap, hiring guidance, vendor evaluation, and AI strategy — 10-20 hours per week.

Ideal for funded startups without a technical co-founder, or companies scaling their engineering function.

Ongoing / 10-20 hrs/week
Urgent

Rescue Mission

Fix broken systems, unblock teams, clean up technical debt. Root cause analysis, hands-on fixes, automated testing and CI/CD setup, and AI-assisted maintenance so it stays fixed.

Ideal for companies where something critical has broken down and needs a senior engineer, not another meeting.

1-3 months / Fixed scope

An AI Agent Team That Ships Code Around the Clock

Challenge
Build a solo-founder operation producing team-level output across iOS, backend, and infrastructure simultaneously
Scope
Two App Store apps, two FastAPI inference backends, ONNX runtime serving, full CI/CD, self-hosted infrastructure
Result: Deployed a 9-persona AI agent team operating as a virtual engineering organization — planning, coding, reviewing, and deploying continuously. Two iOS apps live. ONNX inference backend serving real users. This is the system we build for clients, customized to their domain.
Claude AI ONNX Runtime FastAPI React Native Ansible

The combination no other firm offers.

German national. Physics background. Ten years in US big tech. Now building AI infrastructure for European companies at exactly the moment they need it.

Silicon Valley Scale, Not Silicon Valley Assumptions

We have built systems handling 10M+ requests per second. We know the difference between a demo and a production system. European companies deserve the same engineering rigor — without the lock-in, the complexity, or the cultural mismatch of US-first software.

GDPR by Design, Not by Afterthought

Privacy compliance was a constraint we engineered around at Uber — not a legal checkbox at the end. Every system we build starts with data minimization, retention policies, and deletion strategies. DSGVO compliance is not an add-on. It is the architecture.

German Entity, Berlin-Based

Westover Labs operates as a German UG. Contracts are straightforward for European companies. No currency risk, no cross-border complexity. We are in your timezone, in your regulatory environment, and aligned with how European businesses operate.

We Leave. The System Stays.

Most consultants create dependency. Our engagement model is designed to do the opposite. We build AI infrastructure that keeps working after we leave — documented, trained, and handed off. You own everything. No retainer required. That is the whole point.


How a 3–6 month engagement works.

No retainers, no ambiguity. A fixed arc with defined deliverables at every phase — and a clean handoff when we are done.

What Your Team Keeps After the Engagement

  • Production AI infrastructure, fully deployed
  • Architecture decision records with rationale
  • Runbooks for every system we build together
  • CI/CD pipelines with automated testing
  • Monitoring and alerting configuration
  • Trained team capable of owning everything

One month. €10K. You know exactly what you are getting.

Instead of a months-long hiring process: engage us for a trial month. We assess your architecture, start building, and mentor your team. After 30 days you have actual output, not a pitch deck.

01

The Recruiter Math

A recruiter charges 15–20% commission. On an €80K hire, that is €12,000–16,000 just for the introduction — and you still do not know if the hire will work out. A trial month costs less and delivers real output you can evaluate directly.

02

What Happens in the Trial Month

Weeks 1–2: architecture assessment and stack audit. Weeks 3–4: first production systems built, team mentoring running in parallel. At the end of 30 days you have tangible deliverables and a clear read on fit.

03

What You Keep Either Way

Systems that run. A team that understands how they work. If it is a fit, we continue. If not, you are out less than you would have paid a recruiter — and ahead on architecture regardless.

The Berlin market is correcting. Staff engineers at FAANG companies earn $750K–1M+ total compensation. The same title in Berlin pays €110–140K. Google just opened their AI Center in Berlin-Mitte with €5.5B committed through 2029. Senior engineers know what their work is worth — and the gap to the US market is narrowing. Don’t take our word for it: levels.fyi/Berlin.

Every engineer James Westover hired at HERE Technologies and Uber is still there — in the Bay Area where average tenure is 18 months. That is not luck. It is the result of leveling correctly, paying fairly, and actually mentoring people. That comes with the engagement.


I’m Done With Recruiters.

A recruiter reads a CV. We know what good engineers actually look like — because we hired and retained them at Uber and HERE Technologies across a decade and thousands of microservices.

New

“I’m Done With Recruiters”

Direct hiring, no commission. We source, screen, and hire your engineering team. No middleman. No keyword matching. Someone who understands what strong engineering performance actually looks like — and has the track record to prove it.

Recruiters charge 15–20% per hire. For an €80K salary, that is €12K–16K per person, just for an introduction. For €20K you get an experienced hiring manager personally evaluating every candidate. For multiple hires, the math works out immediately.

€20,000 / Hiring package
