Generalist AI or Vertical AI: which to pick
A general assistant like ChatGPT for the whole company, or agents built for a specific process. What actually fits a B2B SME.
In brief
For most B2B SMEs, use generalist AI (horizontal, e.g. ChatGPT or Copilot) for broad productivity and early experiments, and move to vertical AI (industry-specific, a custom-built agent) when a single core, repetitive process burns more than ~5 hours a week: at that point the custom-built agent pays back. Generalist AI is cheap and instant but stays generic; vertical AI costs more upfront but executes the process with precision on your data. It is not either-or: they almost always coexist.
Option A
Generalist AI (horizontal)
General purpose tools like ChatGPT, Claude or Microsoft Copilot, used by people to write, summarise, search and reason on any topic.
Pros
- +Low, immediate cost: licences from a few euros per person per month
- +Zero setup: people start today, no project needed
- +Covers a thousand different use cases, from email to brainstorming
- +Great to get the team AI-literate before investing more
Cons
- −It does not know your processes, data and rules: generic answers
- −Output depends heavily on who writes the prompt
- −It does not run tasks end-to-end in your systems (CRM, ERP)
- −Data and compliance risk if used without governance
Best for
- Broad individual productivity across the whole company
- SMEs early in their AI journey wanting low-risk experiments
- Creative and research work that is not standardised
Option B
Vertical AI (industry-specific)
AI agents built for a specific process (CV screening, reconciliations, lead qualification), integrated with your data and systems.
Pros
- +Executes the process end-to-end, not just suggests
- +High accuracy because it works on your data and rules
- +Measurable ROI on a process (e.g. hours saved per week)
- +Built-in governance and audit trail, useful for GDPR and the AI Act
Cons
- −Higher upfront cost (Assessment ~2,000 euro, Sprint 10-50k)
- −Only makes sense on repetitive, high-volume processes
- −Needs an internal owner to follow the project
- −Must be maintained when the process or systems change
Best for
- Core, repetitive, high-volume processes
- B2B SMEs wanting measurable ROI, not just vague productivity
- Companies with compliance and decision-traceability needs
| Criterion | Generalist AI (horizontal) | Vertical AI (industry-specific) |
|---|---|---|
| Starting cost | A few euros/person per month | Assessment ~2,000 euro + Sprint 10-50k |
| Time to start | Today | First delivery in 4 weeks |
| Knowledge of your processes | None (generic) | High (your data and rules) |
| What it actually does | Suggests and assists | Executes the process end-to-end |
| ROI | Broad but hard to measure | Measurable on a process |
| Compliance and audit | Must be governed separately | Built-in audit trail |
The verdict
It is not a binary choice: the two coexist. Generalist AI is the cheapest, fastest way to get the team AI-literate and cover a thousand micro-tasks, but it stays generic and does not run your processes. Vertical AI costs more upfront, yet on a core, repetitive, high-volume process it pays back with measurable ROI and precision. The right question is not 'which AI', but 'which processes deserve a dedicated agent and where a generic tool is enough'. For most B2B SMEs: generalist for everyone, vertical on the 2-3 processes that weigh most.
