8 Best Open Banking Solutions for Businesses

The best open banking solution for you depends on one thing: what you actually need it to do. Do you want to initiate payments, pull account data, or both? Answer that first, and the shortlist gets short fast. In our experience working with fintechs and platforms, this is where most teams should start.

This guide compares eight leading open banking companies. I look at API depth, regulatory coverage, payment initiation, and scalability. Each one fits a different job, so I have flagged who each suits best and where each one falls short.

The market is moving quickly. Analysts expect open banking to reach $120 billion by 2031, and more than 76 million consumer accounts already use FDX APIs. That growth makes your choice matter. As you compare, weigh API quality, PSD2 compliance, payment initiation, data access, integration effort, and pricing. Here are the eight open banking solutions I would put on your radar.

Open Banking Solutions: Quick Overview

Short on time? Here are my top picks by category:

• Best overall open banking solution → ConnectPay
• Best for open banking API infrastructure → TrueLayer
• Best for account aggregation → Plaid
• Best for payment initiation → Token.io
• Best for enterprise open banking → Tink (Visa)
• Best for developer-first integration → Yapily

I break down each one below, with notes on API, compliance, and coverage so you can match one to your needs.

8 Best Open Banking Solutions

1. ConnectPay

Best for: European businesses and fintech platforms needing PSD2-compliant open banking infrastructure combined with a full embedded finance stack.

I will be upfront: this is our platform, so read this section with that in mind. ConnectPay suits teams that want more than raw API data. We give you compliant, API-first infrastructure that runs open banking payment flows, account management, and embedded financial services in one place.

Compliance sits at the core. We build PSD2 and PSD3 compliance straight into the platform, and we hold an EMI license under EU supervision. AML and KYC run natively, not as bolt-ons.

On payments, our API-first setup handles open banking payment initiation and account access. SEPA and SEPA Instant move money in real time. Multi-currency IBAN accounts let you collect funds locally and skip international fees. Take a marketplace paying out 500 sellers: it can trigger initiation calls programmatically, then reconcile each payout against its own IBAN.

What sets us apart from standard open banking API providers is scope. We pair payment initiation with the full stack those flows need: accounts, cards, wallets, and compliance. Most open banking companies stop at data or rails. We build the infrastructure around them.

This fits fintechs, SaaS platforms, marketplaces, and businesses scaling across Europe. See our banking APIs to explore how the pieces connect, and read how open banking drives high conversion at low cost for online businesses.

2. TrueLayer

Best for: Developers and fintechs building open banking payment and data products across Europe and the UK.

TrueLayer is a leading open banking API provider. I rate it highly for payment initiation and data access across the UK and Europe. Teams use it to build open banking payment solutions on rails they can trust.

Its bank coverage runs deep across the UK and EU. That matters more than people think. Open banking products succeed or fail on connection quality, and strong coverage keeps payments and data requests working. TrueLayer supports both payment initiation and account information, so it covers the two core jobs.

The developer experience is a real strength. The docs are clear, which cuts integration time for technical teams. Picture a lending app that needs to verify income: it can pull permissioned transaction data in one flow, then score the applicant. That speed is why major fintechs and neobanks rely on it.

Where it stops short is the wider stack. TrueLayer focuses on open banking APIs, not full financial infrastructure. If you also need accounts, cards, and compliance, you will add those elsewhere.

For teams building payment and data products across Europe and the UK, TrueLayer is a strong, trusted pick.

3. Plaid

Best for: Businesses needing account aggregation and financial data connectivity, primarily in the US market.

Plaid leads on account aggregation, and it owns the US market. It connects apps to thousands of banks, so you get reliable access to account and transaction data. If data is your priority, this is one of the best open banking solutions to shortlist.

Breadth of connectivity is its core strength. Plaid links to a huge network of institutions. That is why so many fintech apps use it to verify accounts, check balances, and pull financial data. Take a budgeting app onboarding a new user: it can connect their bank in seconds and start categorizing spend right away.

Plaid started US-first, but it keeps growing in Europe. That widens its appeal for teams working across both regions. Its strongest coverage still sits in the US.

The thing to watch is payment initiation. Plaid centers on data, not payments, so it trails European providers built around PSD2 payment flows. If you need account-to-account payments, a dedicated initiation provider will serve you better.

For US-focused teams that need solid account aggregation and data connectivity, Plaid is the market leader and a safe choice.

4. Tink (Visa)

Best for: Enterprise businesses and financial institutions needing open banking data and payment infrastructure at scale.

Tink is one of the top open banking solutions for enterprises. It brings strong European coverage and the weight of Visa behind it. Visa acquired Tink in 2022, which adds credibility and deep resources.

Its coverage is properly pan-European and spans banks across many markets. That suits large businesses and financial institutions that need consistent access across the continent, not just one country.

Tink handles both account aggregation and payment initiation. It also stands out on data enrichment. It turns raw transaction data into clean, categorized insights. A bank building a money-management feature can feed enriched data straight into the app, so users see their spending sorted by category from day one. For enterprises, that enrichment adds real value on top of basic access.

The trade-off is complexity and cost. Tink runs an enterprise pricing model with heavier onboarding. That points it at larger organizations, not early-stage startups. It is built for scale.

For enterprises and institutions that need robust, pan-European data and payment infrastructure with strong enrichment, Tink is a proven, credible choice.

5. Yapily

Best for: Developer-first teams building open banking integrations across Europe.

Yapily is a developer-friendly infrastructure provider. Among the open banking companies technical teams reach for, it stands out for a clean API and a strong developer experience. It fits teams building open banking products from scratch.

The API design is its defining strength. Yapily gives you a clean, well-documented interface that cuts friction during integration. Developers who want clarity and control will feel at home. A payments startup can wire up its first initiation flow in days, not weeks, then extend it market by market.

Coverage is pan-European and spans banks across many markets. That lets you build integrations that work across the region, not just one country. Yapily supports payment initiation and account data access, so it covers the core jobs.

Yapily positions itself as pure open banking infrastructure. That suits teams who want flexible building blocks rather than a packaged product. If you need a full financial stack alongside open banking, you will combine it with other providers.

For developer-first teams building integrations across Europe, Yapily is a clean, capable choice worth a close look.

6. Token.io

Best for: Businesses prioritizing open banking payment initiation and account-to-account payment flows.

Token.io is a specialist among the top open banking payment solutions. It focuses on payment initiation and account-to-account flows. Rather than chase every use case, it does bank-based payments well.

Payment initiation is its core strength. Token.io moves money directly between bank accounts and skips card networks entirely. Take a utility company collecting monthly bills: it can send each customer a bank payment request and receive funds straight to its account, no card details involved.

Cost is a key advantage. Account-to-account payments avoid card scheme fees, so Token.io usually charges less than card-based options. For high-volume businesses, those savings add up fast.

Where it does less is data. Token.io is not built for account aggregation and enrichment the way Plaid or Tink are. If your main need is rich financial data rather than payments, those providers fit better.

For businesses that put payment initiation first and want low-cost account-to-account flows, Token.io is a strong, purpose-built specialist worth shortlisting.

7. Nordigen (GoCardless)

Best for: Businesses needing open banking account data access with a focus on bank payment collection.

Nordigen is an accessible pick among the best open banking platforms, and it now sits inside GoCardless. It made its name with free account information API access. That lowers the barrier for teams that need open banking data without a big bill.

Free data access is still its headline. You can connect to bank accounts and pull account information without the fees many rivals charge. Startups and cost-conscious teams love this. Strong European bank coverage backs it up.

The GoCardless acquisition matters. GoCardless leads on direct debit and bank payment collection, so Nordigen slots neatly into recurring collection workflows. A subscription business can verify a customer’s account through Nordigen, then set up direct debit through GoCardless in the same journey.

The limit is scope. Nordigen does not handle complex payment initiation or full infrastructure needs. Treat it as an accessible data and collection provider, not a complete payments platform.

For teams that want affordable account data access alongside bank collection, Nordigen and GoCardless make a practical pair.

8. Aiia (Mastercard)

Best for: Nordic and European businesses needing open banking data and payment solutions with strong regional coverage.

Aiia rounds out my list of open banking solutions. It is a regionally strong provider with Mastercard behind it. Mastercard acquired Aiia, which pairs enterprise credibility with deep Nordic coverage.

Its regional strength is the standout. Aiia covers the Nordics and the wider EU well, so it fits businesses with a real presence in those markets. Where some providers spread thin, Aiia goes deep in the Nordics. A Nordic neobank can connect to local banks its customers actually use, rather than settle for patchy coverage.

The Mastercard link adds weight. It gives Aiia the resources and credibility of a global payments network. That reassures enterprises and institutions choosing a long-term partner, and it supports continued investment in the platform.

Aiia supports account data access and payment initiation, so it covers the core jobs. That makes it a well-rounded option for teams that need both data and payments inside its coverage area.

For Nordic and European businesses that want data and payment solutions with strong regional coverage and enterprise backing, Aiia is a credible, focused choice.

How to Choose the Best Open Banking Solution

Choosing among open banking solutions comes down to matching capability to your use case. Here is how I work through it with teams.

Define your use case first. Do you need payment initiation, account aggregation, data enrichment, or a full embedded finance offering? This one answer cuts the list of open banking companies fast, so start here.

Verify compliance. Check that the provider meets PSD2 and any regional rules in your markets. Compliance is not optional, and it protects you and your customers.

Assess the API. Test API quality, docs, and integration effort. A clean API saves you weeks of build time and cuts maintenance later.

Check bank coverage. Confirm the provider connects reliably to the banks your customers use. Coverage gaps cap what your product can do.

Decide on scope. Do you need a standalone API or full financial infrastructure? If you also need accounts, cards, and compliance, a full-stack provider serves you better.

Check pricing. Some providers hide fees that lift your real cost. Model your expected usage before you sign.

Plan for scale. Pick one of the best open banking platforms that grows as your volume rises.

Priorities shift by business type. Fintechs should lead with API depth, regulatory coverage, and payment initiation. Marketplaces should focus on aggregation and reconciliation. SaaS teams should value recurring initiation and developer experience. Enterprises and institutions should weigh regulatory standing, embedded compliance, and reliable euro zone payments.

Benefits and Challenges of Open Banking Solutions

Open banking brings real upside, but I want to be straight about the trade-offs too.

Start with the benefits. Open banking moves money directly between bank accounts, so payments and transfers run faster and cost less. It supports alternative credit scoring built on real-time data, which opens lending to more people. It pulls data from many institutions into one view, so you manage finances with a fuller picture.

It also lifts customer retention through personalized insights. A budgeting app can flag when a user overspends, then suggest a fix. That keeps people coming back. Open banking pushes fintechs and banks to innovate as they compete. And it can reach underserved groups. Consider this: 42% of adult Americans cannot access mainstream credit rates, and open banking data can help close that gap.

Now the challenges. Weak security can lead to data breaches, so connections need real protection. Stitching together several third-party APIs creates integration headaches and extra engineering. Compliance takes ongoing time and resources to maintain.

Operational risk is real too. Patchy quality among third-party services can break your flows. And when errors cross a chain of providers, accountability blurs. Pick a well-regulated, reliable provider and you cut most of this risk. To see how the models differ, read open banking versus banking-as-a-service.

Build Smarter Payment Flows With Open Banking

The best open banking solutions differ a lot. They vary in regulatory coverage, API depth, and whether they offer payment initiation, data aggregation, or both. There is no single winner. There is only the provider that fits your use case, markets, and growth plans. A data-first US app and a payments-first European platform need very different things.

If you run a European business and want open banking payment flows plus compliant financial infrastructure, I would point you to ConnectPay. We pair PSD2-compliant open banking with the full stack those flows need, from accounts to compliance, in one place.

Open banking drives competition and innovation across finance, and the opportunity keeps growing. Choose the right provider now, and you position your business for the $120 billion market expected by 2031. Think long term. Pick a solution that scales with your usage, not one you outgrow. Get the foundation right today, and you save yourself a painful re-platform as open banking becomes central to how money moves.
