Fintech Companies in Cardiff: 33 Active Firms (2026)
Fintech companies in Cardiff build financial software, payments, lending, compliance and data services for FCA-regulated UK markets.
Buying centres in the Cardiff cohort sit around finance operations, payments integration, lending administration, risk and compliance teams, rather than retail consumer acquisition alone. The typical buyer is a regulated financial-services firm, a software platform embedding payment or account-access functions, or a mid-market business with treasury and credit workflows to automate. Sales cycles tend to be evidence-led: security review, conduct-risk ownership, integration work and operating resilience matter before procurement signs off. Engagements are usually departmental or platform-level deployments, with implementation work shaped by whether the service touches client money, regulated lending, account data or payment initiation.

Cardiff has 33 actively trading fintech firms in this list, a compact city cohort by UK standards but one with a clear B2B and regulated-services bias. Reported headcount totals 206 people, so the employment footprint is modest and concentrated in specialist product, engineering, compliance and commercial roles rather than mass operations. A small subset reports larger turnover, while newer incorporations keep the local pipeline replenished. The Cardiff and wider South Wales setting matters commercially: proximity to public-sector buyers, financial-services operations and university-linked technical hiring tends to favour specialist infrastructure and compliance tools over consumer brand-building.
UK obligations attach to the activity, not to the fintech label. Payment-account operation, card payments, acquiring, money remittance, account information and payment initiation fall within the FCA perimeter when offered as a regular UK business activity, with authorisation or registration routes depending on the model. E-money issuance sits under a separate FCA authorisation or registration regime unless an exemption or existing permission applies. Cardiff firms working in cryptoasset infrastructure face a moving perimeter: the FCA has said new regulated activities will bring in-scope cryptoasset business under its remit, so product design and compliance planning need to allow for authorisation rather than only anti-money-laundering registration.
Cardiff’s fintech outlook appears shaped less by consumer-app land grabs and more by regulated workflow depth. The cohort tends to suit buyers that need account access, payment execution, credit operations or compliance evidence embedded into existing systems. That favours patient sales motions and domain expertise, but it also limits the number of firms likely to scale through broad self-serve adoption. Consolidation may come from larger financial-technology and software groups looking for regulated capability, while local start-ups are likely to keep forming around narrow pain points where financial-services operations, data handling and conduct obligations overlap.
What’s in the file
One row per company, 50+ columns — everything below plus each company’s verified directors, from Companies House filings.
Company data
Verified directors — included
Active director count is the full Companies House board, so it can be higher than the number of names listed — we leave out nominee and formation-agent directors, who aren’t worth contacting. It’s blank for the small number of companies whose officers we haven’t fetched yet.
You’re charged per business, not per row. Where a business trades through several registered companies you get every one, and the Group Primary column marks one row per business — filter to those and the count matches your invoice. Rows sharing a website are not automatically one business: franchises and multi-site operators each count separately, and where names don’t prove a relationship we count them apart rather than guess.

Key facts
About 15% of the trading cohort reports turnover above £5M (5 of 33 firms) — the rest sits below that revenue band.
18% of the cohort was incorporated since 2022 (6 firms), so a sizeable share is in its first few filing cycles.
Payment services fall under the Payment Services Regulations 2017, covering payment-account operation, card payments, acquiring, money remittance, account information services and payment initiation services.
E-money issuers must be authorised or registered by the FCA under the Electronic Money Regulations 2011 unless exempt or already permitted under FSMA.
The FCA expects the new cryptoasset regime to come into force on 25 October 2027, after which in-scope cryptoasset businesses will need FCA authorisation to operate in the UK.
HM Treasury stated in April 2026 that over 3,000 fintech firms operate across the UK and attracted over £2.6 billion in investment last year.
Innovate Finance reported that the UK retained second place in global fintech investment rankings in 2024.

How Cardiff Fintech companies work and how to sell to them
What they do
Cardiff fintech firms usually earn revenue from a mix of recurring platform fees, transaction charges, implementation work and regulated support services. Payment and account-access providers tend to price by usage, while lending, treasury and compliance tools more often use annual subscriptions with onboarding fees and support tiers. The product is normally software plus integration: APIs, dashboards, risk engines, workflow tools and reporting layers that sit inside a bank, finance team or software platform. Smaller engagements may begin as a paid pilot or integration sprint, but production use usually depends on security review, operational ownership and evidence that the service can handle regulated money, credit or account information without creating avoidable conduct risk.
Who they sell to
Customers are usually regulated financial-services firms, embedded-finance platforms, lenders, payment intermediaries, accounting-led finance teams and mid-market businesses with treasury or credit operations to manage. Buying committees tend to include a commercial sponsor, a CTO or engineering lead, a compliance owner, finance leadership and procurement where the buyer is larger. Contract size is typically tied to operational risk rather than headcount alone: a narrow reporting tool may be bought by one department, while a payment or lending workflow can become a platform procurement. Sales cycles often run through direct sales, partner introductions and formal review, with RFP-style processes more common where client money, customer data or outsourced operations are involved.
What they buy
Most Cardiff fintech firms tend to spend on infrastructure and controls before broad front-office expansion. Useful categories include cloud hosting, API management, data warehousing, monitoring, identity and access management, security testing, incident response, compliance workflow, audit evidence, customer support tooling, CRM, billing and revenue operations. Specialist services can also fit: FCA authorisation support, legal review, financial modelling, accounting, tax, recruitment for engineering and compliance roles, and content or demand generation aimed at regulated buyers. Teams selling into this segment usually need to show how their offer fits procurement, risk ownership and implementation capacity, rather than relying on generic productivity claims.
Why and how to sell to them
Fintech buyers tend to evaluate vendors when regulation, integration load or customer growth exposes a gap in their operating model. Useful triggers include a new regulated activity, a payment or lending product moving from pilot to production, a senior finance or compliance hire, a funding event, a security review, or a larger customer asking for audit evidence and service-level commitments. Outbound works better when it is specific about the workflow being improved: faster onboarding, cleaner reconciliation, lower manual review, clearer incident reporting, more reliable integration testing or simpler evidence packs for regulated customers. Claims need proof, because these buyers are paid to distrust vague assurances.
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.
