Enterprise AI Platform Comparison — 2026

MAIA Brain vs Google Vertex AI
Purpose-Built Enterprise AI vs a Developer Platform You Still Have to Build Yourself.

Google Vertex AI is a powerful ML infrastructure platform — but it requires data science teams to build, maintain, and govern every pipeline from scratch. European enterprises need something that works out of the box, on-premise, with no ML expertise required. That is what MAIA Brain delivers.

The Plain-English Answer

Google Vertex AI is a world-class ML infrastructure platform — built for organisations with mature data science teams who need to build, train, and deploy custom machine learning models. It is not an enterprise automation platform; it is a toolkit. European enterprises comparing MAIA Brain and Vertex AI are often comparing two fundamentally different things: MAIA delivers ready-to-run AI automation for business operations, while Vertex AI gives data engineering teams the infrastructure to build AI solutions from scratch. The difference in time-to-value, engineering overhead, and regulatory compliance posture is significant. For a broader understanding of MAIA's automation approach, see Intelligent Automation and our AI Automation Platforms Compared 2026 overview.

Cost Advantage

Significantly Less. Everything Included.

The sticker price of Google Vertex AI is only part of the story. Building enterprise automation on Vertex AI requires ML engineers, data scientists, DevOps and MLOps infrastructure, model monitoring, retraining cycles, and ongoing Google Cloud consumption costs. MAIA delivers the same operational outcome — without any of that build cost.

Why Vertex AI Costs Far More Than It Appears

Google Vertex AI is infrastructure-as-a-service. Every operational capability — document processing, exception handling, compliance controls, enterprise connectors — must be designed, built, and maintained by your team. For European enterprises without large ML engineering departments, the true cost of a Vertex AI-based automation programme typically exceeds the all-in cost of MAIA Brain by 60–70%, before accounting for the 12–18 month delay to production value.

What MAIA Brain Does That Vertex AI Cannot — Out of the Box

Vertex AI is infrastructure. MAIA is a running platform. The distinction matters enormously for time-to-value. See our full AI Automation Platforms Compared 2026 for a broader market view.

Business-Ready From Day One

Vertex AI is infrastructure that needs building before it does anything. MAIA Brain is a running platform configured for your processes in weeks, not months. No pipeline to design, no model to train, no MLOps team to hire.

Live in 4–6 weeks
Vertex AI: 6–18 months to production value

Honest Advice

Which Platform Is Right for You?

We believe in honest comparison. Google Vertex AI is genuinely excellent for the right use case — but that use case is not enterprise operations automation for most European businesses. Also compare MAIA vs Blue Prism and MAIA vs UiPath if you are evaluating traditional RPA platforms.

Consider Vertex AI If...

  • Your team includes experienced ML engineers and data scientists with capacity to build and maintain production pipelines
  • You need to build custom AI models for highly specialised tasks that no off-the-shelf platform addresses
  • Your workloads require fine-tuned foundation models trained on proprietary data for competitive differentiation
  • Cloud-first Google infrastructure is your company-wide strategy and data sovereignty is not a constraint
  • You have 12 or more months to invest in build before expecting operational ROI

MAIA Brain Is Likely the Better Fit If...

  • You need enterprise automation running in weeks, not years, and cannot wait for a pipeline build programme to complete
  • Your operations team needs to configure and manage automations without ML expertise or specialist engineering resource
  • EU data sovereignty or GDPR obligations require data to remain on your premises — not on Google Cloud infrastructure
  • You need predictable, transparent pricing without consumption-based cloud billing surprises as automation scale grows
  • Document-heavy processes need intelligent automation without custom model training or Document AI configuration work
  • You need built-in EU AI Act compliance — audit trails, explainability, and governance controls — without custom engineering effort
Client Experience
"

We evaluated Google Vertex AI as part of our automation programme. The platform is genuinely impressive — but we quickly realised we were looking at an 18-month engineering project before seeing any operational impact. MAIA Brain was live in six weeks, running on our own servers, processing documents and handling exceptions without any data science team involvement. The difference in time-to-value was not incremental — it was transformational.
