Custom AI Agent Build

Generic AI tools are built for generic use cases. Your specific workflow — your data, your customers, your business logic — needs an agent trained and configured specifically for it. We design, build, integrate, and hand over custom AI agents that work in your world.

Pricefrom £8,000 / project
Timeline4–8 weeks to production
Ideal forBusinesses with a specific high-volume, rule-based, or knowledge-intensive workflow currently handled manually.
[ Outcome ]

A production-grade AI agent handling a specific workflow in your business — with full documentation and a trained team.

Custom AI agents are the highest-leverage form of AI deployment — because they’re built around the specific task, the specific data, and the specific quality standard that matters to you.

They don’t hallucinate about your products because they’re trained on your product data. They don’t give wrong policy information because they’re constrained to your policy documents. They don’t respond in the wrong tone because they’re trained on your brand voice.

✓ Who it's for

For businesses with a specific identifiable workflow that meets three criteria: it’s high volume (hundreds or thousands of times per month), it’s currently handled manually, and it has a definable quality standard.

Common use cases: customer service triage, lead qualification agents connected to portals and CRMs, internal knowledge retrieval, automated proposal generation, lease and contract abstraction.

✗ Who it's not for

Vague briefs ("we want an AI agent that does everything") or use cases without a definable quality standard. If you're not sure what the workflow is, start with the AI Launchpad.

The AI Agent Use Case Library: 25 Proven Builds by Function

25 real-world AI agent use cases organised by business function — customer service, sales, operations, HR, finance, marketing. Each entry includes: workflow description, data requirements, estimated build complexity, and typical ROI metrics.

Used as the starting point in every Zinerge agent discovery conversation.

[ FAQ ]

Common questions.

What AI models do you build on?

Primarily Claude (Anthropic) and GPT-4o (OpenAI), chosen based on the specific task requirements. For retrieval-heavy knowledge agents, we often use Claude for its large context window.

How do you handle data security and GDPR?

All agent builds operate under a signed Data Processing Agreement. We use model APIs with business tier privacy guarantees — client data is never used for training. For sensitive data, we can architect for on-premise or private cloud deployment.

What happens when the agent gets something wrong?

Every agent has defined escalation triggers — edge cases or confidence thresholds that route to a human. The runbook documents every escalation path. During the 30-day support period, we review output quality weekly and retrain on failure cases.

Is £8,000 the full cost including API usage?

The £8,000 build fee covers design, development, training, integration, testing, and handover. Ongoing API costs (typically £50–£500/month depending on volume) are billed directly to your account.

Can we expand the agent's capabilities after launch?

Yes. Agent expansion is typically scoped as a separate project once the initial build is stable. Most clients return for a second phase within 3–6 months.

You have a workflow that should be running itself.
