Built for fintechs, banks, and compliance teams that need fast programmatic verification without paying enterprise KYC suite prices.

Built for

  • Fintechs and banks doing partner / introducer / customer onboarding
  • Compliance teams at SME professional services firms
  • Marketplaces verifying financial professionals
  • Consumer apps doing point-of-purchase advisor verification

Data sources

How we compare

ProviderEntry priceWhere they fall short
SmartSearch~£200/monthBundled into a full KYC suite, no standalone FCA-only tier
Credas~£250/monthIdentity-verification focused, FCA lookup is incidental

Reliability you can build on

Built on the same AWS infrastructure that runs UK banks and government services. Engineered for the kind of always-on availability your compliance workflow expects.

Target 99.9% uptime

Stack uptime is governed by AWS API Gateway (99.95%), Lambda (99.95%) and DynamoDB (99.99%) SLAs. We target 99.9% end-to-end, which works out at roughly 8 hours of downtime per year, worst case.

Hosted in London (eu-west-2)

Single-region UK hosting for low latency to UK customers and predictable data residency. Median response under 250ms; 5-minute response cache absorbs upstream blips.

Idempotent + cached

Repeat lookups within 5 minutes are served from cache, so transient FCA upstream issues don't propagate to you. Bulk endpoint runs with bounded concurrency to never overrun the source.

Contractual SLA on Pro

Pro plan includes a 99.9% uptime commitment, priority support with response in under 4 hours (UK business hours), and a private Slack channel for incident escalation.

Live status visibility lands with the public dashboard. Full incident history available to Pro customers on request.

Why this pricing?

At £19/month, the Starter tier sits below the threshold where most B2B buyers spend time evaluating alternatives. You get a normalised JSON response, sensible status semantics for complex regulated entities, cross-reference against the SRA register for solicitor-led firms, and consistent uptime backed by AWS. Larger KYC and AML suites such as SmartSearch and Credas start at £200 to £500 per month and bundle in identity verification and broader screening you may not need.

Missing something?

Need a field we don't return, a regulator we don't cover, or a workflow our pricing tiers don't fit? Tell us. We're small enough to ship custom changes quickly: sometimes free, sometimes for a one-off fee, always with a fast yes/no on whether we can do it.

We respond personally within 2 business days.
