Is this service a good fit?
Good fit if
Companies wanting internal assistants, ticket triage, or structured extraction with traceable LLM usage.
When we are not a fit
Magic demos without data or privacy policies, or “clone ChatGPT” without a measurable use case.
Typical deliverables
Prompt design, evaluation, connectors to your docs/CRM, and cost-per-use estimates.
Use case
Frequent win: faster first responses in support with consistent quality.
Quick questions
OpenAI or open-source? Depends on compliance and cost.
Fine-tuning? Only with a dataset and clear ROI; often RAG + solid prompting is enough.
First reply usually in under 30 minutes with feasibility and missing inputs.
How we put LLMs into production
- Measurable use case (time, quality, volume) before choosing models and architecture.
- Traceability and guardrails: data boundaries, retention, human review and minimal audit logs.
- Evaluation with a test set and estimated cost per use—not a one-off a demo without real data.
- Gradual rollout (internal pilot → small group → production) with a clear rollback path.
Compliance is your legal/DPO context; we implement technical controls agreed in writing.
What we measure in AI pilots (no hype)
A useful pilot should reduce uncertainty on quality, cost and risk. We avoid promising “full automation” without a process owner and clean data.
- Operational quality: precision/recall on a business-reviewed label set (with explicit disagreements).
- Latency and cost: p95 response time and cost per 1k tokens (or equivalent) with an agreed ceiling and alerts.
- Human-in-the-loop: when human review is mandatory and how it is audited (minimal logs, bounded retention).
Compliance for sensitive data is owned by your legal/DPO; we implement the technical controls you approve.
How we work with you
Goals, integrations, priorities and timeline or budget constraints.
Feasibility, phased scope and collaboration model via email.
Implementation, testing and deployment with clear milestones.
Post-launch fixes and iterative improvements as agreed.
Outcomes we optimise for
Stable production systems, less operational friction for your team and maintainable code. We judge success by real usage and time saved—not only by shipping files.
FAQs for bespoke projects
Fixed price or time & materials? We use fixed phases when scope is stable; T&M when discovery or changes are frequent—clarified in the proposal.
What do you need to start? Problem statement, sample flows or screenshots, technical access when relevant (repos, staging), and a single decision-maker contact.
Maintenance after launch? Yes—corrective support, small evolutions or monthly hour bundles depending on your needs.
