Pre-launch · Early access list open

Open Banking,
opened up.

AperioFlow gives you direct Open Banking APIs for UK account data — balances, transactions and account verification — at fair, transparent prices. No gatekeeping, no five-figure minimums. Just the tools new developers need to break into FinTech.

01 — The problem

Open Banking was meant to be open.
The pricing never got the memo.

A

Priced for banks, not builders

A handful of aggregators control access. Sales calls, annual commitments and opaque per-call fees put real data out of reach for anyone without a funding round.

B

A skills gap that feeds itself

If you can't afford to experiment, you can't learn. If you can't learn, you can't get hired. FinTech ends up recruiting from the same small pool.

C

AperioFlow: fair by default

We connect straight to the banks' Open Banking APIs, with no aggregator in the middle, and pass the savings on at honest, published prices. There's a free tier so anyone can ship their first Open Banking integration this weekend.

02 — The platform

Everything you need to build.
Nothing you don't.

Direct to the banks. No middleman.

We build and run our own connections to UK banks' Open Banking APIs, behind one consistent interface. Write your integration once and get normalised data wherever the account lives.

// fetch balances with one call
const res = await fetch("https://api.aperioflow.com/v1/balances", {
  headers: { Authorization: `Bearer ${KEY}` }
});
const { data } = await res.json();
// → [{ account: "Current", amount: 1284.52, currency: "GBP" }]

Account information

Accounts, balances, transactions, standing orders and direct debits — normalised JSON.

Payments: 2028 roadmap

Bank-to-bank payment initiation is planned for 2028, subject to FCA authorisation. At launch, AperioFlow covers account information only.

Consent handled

Hosted consent flows and token lifecycle management so you can focus on your product.

Sandbox first

Realistic test banks and data. Build and demo without touching a real account.

Usage you can see

A live dashboard of every call, with hard caps per plan. No surprise overage bills — ever. When you hit your limit, you choose whether to upgrade.

05 — The mission

The next generation of FinTech
shouldn't need a funding round
to write its first line of code.

We're building AperioFlow for students, bootcamp grads, career-changers and indie hackers — the people who'll build the next great money app if someone just lets them in the door.

  • CappedHard limits, no bill shock.

  • EducationalGuides written for first-timers.

06 — Questions

Good questions.

When does AperioFlow launch?

We're pre-launch. Register your interest and you'll be among the first invited, with launch pricing locked in for early members.

How can you be cheaper than the big providers?

We don't resell another provider's API. We integrate directly with UK banks' Open Banking APIs, so there's no aggregator's margin built into your bill. We don't need enterprise contracts to make the numbers work. We need lots of developers building.

Are you regulated by the FCA?

Not yet. AperioFlow is a brand of Tweed Tyne Technologies Ltd, which has applied to the FCA for registration as a Registered Account Information Service Provider (RAISP). That application is pending. Tweed Tyne Technologies Ltd will be the FCA-registered firm, and live account data will only be available once registration is granted. We'll publish the FCA reference number here when it is.

What happens if I go over my plan's calls?

Your usage is hard-capped. Calls pause at your limit and we'll let you know — you decide whether to upgrade. No surprise overage charges.

Do I need to be a registered company?

Not for the Sandbox plan or for learning. Some live-data use cases carry regulatory requirements; we'll guide you through what applies to your project.

Is my data safe?

Account holder data only flows with their explicit consent, over the regulated UK Open Banking standards. We never sell data.
