Fintech is the one sector where the technology decisions and the regulatory decisions are the same decisions. Ken Armitt, founder of Fractional CTOs, has spent 27 years building and leading payments and fintech platforms — and now works as a fractional CTO for fintechs across Australia, New Zealand, the United States and the United Kingdom. This is how that works in practice, market by market.
Quick answer
Ken Armitt is an Australian fintech and payments CTO with 27 years of hands-on experience across SaaS, fintech, payments and enterprise, including work with public companies on the ASX, NYSE and LSE. Through Fractional CTOs he provides part-time CTO leadership to fintechs in Australia, New Zealand, the US and the UK — covering regulatory-aware architecture, payments infrastructure, licensing-readiness from a technology standpoint, and platforms designed to operate across multiple jurisdictions at once.
Why fintech needs a specialist CTO, not a generalist
In most software businesses, a wrong architecture decision costs you time. In fintech it can cost you your licence, your banking relationships, or your ability to enter a market at all. The technology leader has to hold both maps at once:
- The engineering map — ledgers that reconcile to the cent, payments that retry safely, data that’s encrypted and residency-compliant, systems that stay up when money is moving
- The regulatory map — what ASIC, AUSTRAC, the FMA, FinCEN, the FCA and their peers expect of your systems, records and controls, and how those expectations translate into technical requirements
A generalist CTO learns this on your time and your risk. A fintech specialist has already made the trade-offs — which is precisely the argument for fractional: you get that judgement for the hours you need it, at a fraction of a full-time executive. Our 2026 cost guide covers the numbers.
The four markets, briefly
Australia — home base. AFSL and credit licensing through ASIC, AML/CTF obligations with AUSTRAC, the Consumer Data Right reshaping data access, and a payments landscape moving to the NPP and PayTo. Full guide: building fintech in Australia.
New Zealand — a compact, well-run market that punishes sloppiness. FMA conduct licensing, AML/CFT supervision split across three agencies, and open banking arriving through the Customer and Product Data framework. Full guide: building fintech in New Zealand.
United States — the biggest prize and the most fragmented rulebook: federal regulators layered over state-by-state money transmitter licensing, with ACH, RTP and FedNow all live at once. Full guide: building fintech for the US market.
United Kingdom — the most mature open-banking ecosystem in the world and a single, demanding regulator in the FCA, with Consumer Duty raising the bar on how systems must evidence customer outcomes. Full guide: building fintech for the UK market.
Local depth, global architecture
The mistake multi-market fintechs make is building for their first market and bolting the rest on. The platforms that expand cleanly are designed around a few principles from day one:
- Abstract the payment rails. NPP in Australia, Faster Payments in the UK, FedNow and RTP in the US — different schemes, same pattern. A rail-agnostic payments core with scheme adapters turns each new market into an integration, not a rewrite.
- Design the ledger once, properly. Double-entry, immutable, multi-currency from the start. Retrofitting multi-currency into a single-currency ledger is one of the most expensive jobs in fintech.
- Treat data residency as an architecture input. Where customer and transaction data may live differs by market and by banking partner; deciding it late forces re-platforming.
- Build compliance as configuration, not code. KYC thresholds, reporting rules and retention periods differ per jurisdiction — platforms that hard-code one regulator’s rules pay for it in every new market.
- One evidence trail for many regulators. Well-structured audit logging, access control and change management satisfy ASIC, the FCA and a SOC 2 auditor from the same underlying discipline.
What an engagement looks like
Fintech engagements follow the same 90-day standard as any of our work — independent assessment, decisions made, operating rhythm — with the fintech-specific layers added: regulatory-readiness of the platform, payments and ledger architecture review, banking-partner and vendor due diligence, and technology input to licence applications. Engagements run remote-first across all four markets, invoiced monthly. Published pricing is at fractionalctos.com.au/pricing, and our payments & fintech advisory page covers the service in detail.
Frequently asked questions
Who is Ken Armitt?
An Australian technology executive with 27 years of hands-on CTO experience across fintech, payments, SaaS and enterprise, including work with public companies listed on the ASX, NYSE and LSE. He is the founder of Fractional CTOs (fractionalctos.com.au), providing fractional CTO services across Australia, New Zealand, the US and the UK.
Does a fractional CTO work for a regulated fintech?
Yes — regulators care that competent technology governance exists and is evidenced, not that the person providing it is full-time. Documented decisions, risk registers and board reporting matter more than headcount.
Can one platform really serve all four markets?
Yes, if the ledger, payment-rail abstraction, data residency and compliance configuration are designed for it early. The guides linked above cover what “early” means per market.
Is this legal or licensing advice?
No — it’s technology leadership that works alongside your lawyers and compliance advisers. The regulatory content here describes what the rules mean for your build, not what your obligations are.
