Haystack Development in Cardiff
Building search and retrieval systems on Haystack for Cardiff organisations, where the pipeline is declared rather than implied. Components are wired into an explicit graph you can inspect, swap and measure a piece at a time — which matters because retrieval quality problems are almost always located in one component, and finding out which one is most of the work.
Why this comes up
The problem
Answer quality is poor and there is no way to tell whether the retriever, the ranker or the prompt is responsible.
What you get
What we deliver
- Pipelines defined explicitly, with each component measurable in isolation
- Retrieval and generation evaluated separately, since they fail differently
- Classic keyword search used alongside embeddings where precision matters
- Rankers applied and their contribution actually measured, not assumed
- Document preprocessing tuned to the formats you genuinely hold
- Pipelines versioned, so a quality change can be traced to a specific alteration

Working in Cardiff
Wales
Cardiff has a significant broadcast and media sector alongside a large public-sector presence, and Welsh-language provision is a genuine requirement on public-facing work here rather than a nice-to-have.
Public sector and broadcast work is common, and bilingual provision is usually a requirement rather than an option.

Haystack Development in Cardiff — common questions
- Why evaluate components separately?
- Because an end-to-end score tells you the system is worse without telling you where. If the retriever never returned the relevant passage, no prompt change will help — and teams routinely spend weeks on prompts when the answer was never in the context.
- Is keyword search still useful?
- For exact terms, very. Part numbers, case references, names and codes are matched precisely by keyword search and approximately by embeddings, so systems handling that kind of query benefit from running both rather than choosing.
- Do rankers earn their cost?
- Frequently, and it should be measured rather than assumed. Reranking adds latency and expense, and whether it improves your results depends on your corpus and query patterns — which is exactly the sort of thing a component-level evaluation answers.
- How much does preprocessing matter?
- More than most of the pipeline. Text extracted badly from a PDF, tables flattened into unreadable rows and headers lost from their sections limit everything downstream, and no amount of retrieval sophistication recovers information the ingestion discarded.
- Do you work with businesses across Cardiff?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Wales, including Cardiff and the surrounding Cardiff area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Cardiff businesses do you usually work with?
- Public sector and broadcast work is common, and bilingual provision is usually a requirement rather than an option. Beyond that we work across Media & Broadcasting, Financial Services, Public Sector, Higher Education and Sport.
- Do you cover the areas around Cardiff?
- Yes — we work throughout Wales, including Bristol, Swansea. Cardiff is an urban area of roughly 490,000+, and we take on work across the wider Cardiff region rather than the city boundary alone.
