Data Analytics Companies in Cardiff: 30 Active Firms (2026)
Data analytics companies in Cardiff turn business, operational and customer data into reporting, insight and decision tools for the city region.
Buying centres in Cardiff tend to sit with finance, operations, customer teams and digital change leads rather than a single analytics function. The commercial pattern is mostly business-to-business, with some public-sector work where reporting, forecasting and service-performance evidence matter. Engagements appear to be departmental in scope: data engineering to clean up fragmented sources, dashboards for management reporting, forecasting for planning, and managed analytics retainers where clients lack in-house capacity. Sales are likely to depend on domain familiarity, governance comfort and the ability to turn mixed operational records into decisions a budget holder can use.

Cardiff has 30 actively trading data analytics companies in this cohort, making it a compact city-market rather than a broad supplier base. Reported employment across the cohort is 286 people, which points to small delivery teams and founder-led service firms as much as productised analytics vendors. Only 2 firms sit above £5M turnover, while 6 have been incorporated since 2022. That mix suggests a market with a visible early-commercial layer, a narrow upper end by revenue, and enough recent formation to keep the local supplier base in motion.
Most Cardiff analytics providers do not need a sector licence simply because they analyse data, but UK GDPR and the Data Protection Act still shape routine delivery. The ICO is the relevant UK regulator where personal information is collected, cleaned, profiled, retained or shared. Work involving special category data, automated decision-making or profiling carries additional safeguards, particularly around fairness, purpose limitation, minimisation, accuracy, retention and security. Cross-border personal-data transfers also need a lawful route, such as International Data Transfer Agreements, Standard Contractual Clauses, Binding Corporate Rules or adequacy regulations.
Procurement pressure appears likely to favour providers that can combine practical data engineering with governance evidence, rather than firms selling dashboard design alone. Cardiff’s cohort tends to look service-heavy, so progression may come through managed analytics, embedded reporting support and sector-specific decision tools for clients that lack internal teams. Scarcity at the larger revenue end also points to a market where consolidation, partnerships or specialist niches may matter more than broad platform plays. Regulatory scrutiny around personal data should keep documentation, audit trails and model explainability close to the sales process.

Key facts
About 6% of the trading cohort reports turnover above £5M (2 of 30 firms) — the rest sits below that revenue band.
20% of the cohort was incorporated since 2022 (6 firms), so a sizeable share is in its first few filing cycles.
Data and analytics providers are not generally subject to a single sector licence, but personal-data work falls under UK GDPR and the Data Protection Act 2018.
The ICO regulates UK data-protection compliance, including principles covering fairness, purpose limitation, data minimisation, accuracy, retention and security.
Cross-border personal-data work may require International Data Transfer Agreements, Standard Contractual Clauses, Binding Corporate Rules or adequacy regulations.
GOV.UK estimated 9,600 active, registered data-driven companies, split between 5,500 specialised data infrastructure or software-development services and 4,100 broader data consultancy or management services.
The 2024 UK Business Data Survey found that 9% of businesses handling digitised data transferred data internationally, rising to 36% for large businesses and 26% for medium-sized businesses.

How Cardiff Data Analytics companies work and how to sell to them
What they do
Cardiff analytics providers usually earn revenue through project delivery, retained advisory work and recurring managed reporting. The service shape is often a blend of data engineering, dashboard build, forecasting model set-up and interpretation for non-specialist teams. Pricing tends to follow fixed-scope project fees, day-rate delivery, monthly retainers or subscription access to maintained reporting environments. Product-led firms may package dashboards or decision tools around a particular workflow, but many still sell expert time and delivery confidence. The useful distinction for sellers is whether the firm behaves like a consultancy, a managed-service provider or a software vendor with services attached.
Who they sell to
Most buyers are SMEs, lower-mid-market organisations, local public-sector bodies and departmental teams inside larger employers. Finance directors, operations leads, customer directors, heads of digital, CTOs and procurement teams commonly shape the brief, while the budget holder may be outside the technical function. Contracting is typically direct for commercial work, with referrals and existing relationships carrying weight. Public-sector work is more likely to involve framework access, formal procurement documents and evidence of delivery controls. Sales cycles tend to lengthen where personal information, service performance reporting or cross-departmental ownership is involved.
What they buy
Most analytics firms tend to spend on cloud hosting, storage, integration tools, data quality software, business intelligence environments, workflow automation and secure collaboration systems. As delivery teams mature, they may also need observability, access control, backup, endpoint security, documentation tools and project management systems that help keep client work auditable. Service spend often covers UK GDPR advice, commercial contracts, accountancy, insurance, recruitment and specialist contractors for engineering or visualisation. Marketing suppliers can be relevant where firms are moving from referral-led selling to more defined propositions for finance, operations or public-sector buyers.
Why and how to sell to them
Buying triggers usually appear when a firm wins larger client work, moves from ad hoc projects to retained delivery, hires senior commercial or technical leadership, or faces more questions on governance and audit trails. Pain points tend to sit around delivery capacity, messy source systems, margin leakage on fixed-scope work and proving that reporting outputs can be trusted. Outbound messages are more credible when they connect to a specific bottleneck: faster onboarding of client records, lower rework, clearer documentation, safer handling of personal information or better visibility of project profitability.
How this list is built
Data sources
This list is built from UK Companies House filings, XBRL accounts data, and semantic analysis of each company's public website. Revenue and headcount figures come from the most recent filed accounts; where the company has not filed, values are estimated using a model trained on filed history and peer benchmarks and are labelled as estimates.
Classification
Rather than relying solely on SIC codes, Firmbase classifies each company semantically: the company's website is crawled, an AI model reads what the company actually sells, and the company is placed into the relevant industry and subsectors. SIC codes are used as one signal but not the only one. This means a company that registered under a generic SIC code but pivoted into (for example) fintech is correctly identified as fintech, not as its original SIC category.
Freshness
The underlying company data is refreshed from Companies House continuously; filings appear in the list within days of submission. The curated list ordering is regenerated when the underlying data moves meaningfully (company count changes by more than 5%, a new company enters the top-ranked segment, or the filed-revenue numbers for the top firms change). You can see the last-updated timestamp near the top of the page.
