Small Business Local AI Setup (2025): The Simplest Stack That Actually Works

The simplest local AI stack

For most small businesses, this is the highest-leverage setup:

• Inference: Ollama (developer-friendly, OpenAI-compatible API)
• UI: Open WebUI (ChatGPT-style interface)
• Knowledge: RAG documents (policies, SOPs, product docs, proposals)

Workflows that pay for the machine

• Sales: proposal drafts, objection handling, call summaries
• Ops: SOP generation, checklists, internal policy Q&A
• Support: response drafts grounded in your product knowledge
• Admin: email drafts, invoice/contract summarization

Hardware: what to buy (without overspending)

For most teams, you don’t need a datacenter GPU. You need enough headroom to keep the experience fast for a handful of staff.

• Project Infra A-Server: Startup Edition is designed for running 14B–24B class models with a strong CPU/GPU combo and fast storage.
• If you want a compact office machine, the Minisforum AI X1 Pro line is designed for local workloads and can be upgraded later via OCuLink eGPU.

LAN access without security drama

Small teams often want “one AI box on the network.” Do it safely:

• Keep it on a private subnet / VLAN
• Use authentication at the UI layer
• Log usage and limit who can access which models

When to upgrade to an “AI hub”

If your team grows or you want 3–5 concurrent users with heavier workloads, move from “single workstation” to “private server.” That’s where rack-mountable style systems start to make sense.
