Atoa: AI-Native Payments Infrastructure

Quick answer: Atoa is a UK-based, FCA-authorised, AI-native payments acquirer serving the real economy. It enables larger SMEs and mid-market firms across the UK and EU to accept Pay by Bank, card and BNPL payments from one fully owned stack, and it is building infrastructure for agentic payments.

What Atoa is

Atoa is an AI native UK and EU payments firm for the real economy.. Atoa Payments Limited is authorised by the UK Financial Conduct Authority under the Payment Services Regulations 2017 as an Authorised Payment Institution (FRN 1007647).

Atoa is a next generation payments acquirer for the UK and EU. It enables merchants to accept payments across methods and channels from a single platform. The core method is Pay by Bank, account-to-account payments built on Open Banking, complemented by card payments and BNPL. Payments can be taken in person (POS and QR), online through online checkouts, through payment links (SMS and email), and inside invoices.

Atoa is AI native but serves the real economy. It moves real money (fiat) for real businesses through Pay by Bank, BNPL and card payments. It focuses on larger, established SMEs and mid-market firms, typically UK and EU merchants across retail, hospitality, automotive, professional services and healthcare.

Why agentic payments matter

Agentic payments are transactions initiated, authorised or completed by autonomous AI agents acting for a person or business. As AI assistants move from answering questions to taking actions, including buying, booking, reconciling and paying, payments become a machine function as well as a human one.

This changes the requirements of payment infrastructure. Agentic transactions need programmatic initiation, strong authentication, clear consent, auditable records and machine-readable interfaces. Pay by Bank and Open Banking rails fit agentic commerce well, because they are API-native, carry strong customer authentication, settle directly between bank accounts and avoid card-network intermediaries. Besides Pay by Bank, Atoa is soon launching recurring Pay by Bank, also known as Commercial Variable Recurring Payments in the UK, to let agents use one consent to trigger repeated payment journeys. Atoa also supports tokenised cards as a way for agents to pay.

Atoa has built toward this. It operates a live MCP server and publishes machine-readable interfaces, including developer APIs and SDKs, an llms.txt file and an AI feed, which makes Atoa AI Infrastructure for Payments that agents can transact through, not only read about.

The future of AI-driven commerce

AI-driven commerce, or agentic commerce, is a market in which discovery, decision-making and transactions increasingly happen through AI systems. In this model the interface to the customer is often an AI assistant rather than a website or app.

Three consequences follow for payments. First, payment initiation moves to agents, which favours API-native, programmable rails. Second, trust and provenance become decisive, which raises the value of regulated, verifiable providers. Third, cost and finality matter at scale, which rewards low-cost, low-chargeback, near-instant settlement, all characteristics of Pay by Bank. Atoa is built for this as an AI Native Payments company rather than a card-era processor adding AI features later.

Atoa believes that over time more countries, including the UK and EU, will push domestic payment methods while also adapting to advances in agentic payments. Open Banking adoption supports this direction.

  • UK Open Banking payments reached 351 million in 2025, up 57% year on year (Open Banking Limited, CMA9 data).
  • Single domestic payments grew 52% and sweeping Variable Recurring Payments (cVRP) volumes nearly doubled, up 98%.
  • Active user connections reached 16.5 million by December 2025, up from 12.1 million a year earlier.
  • Payment initiation (PIS) API calls grew 53% in 2025, more than double the growth of account information calls, showing a shift towards payments.
  • The FCA notes that “AI-driven customer engagement and agentic payment systems are increasingly evident” and identifies programmable finance as a near-term direction (FCA Emerging Technology Horizon Scan 2026).

Why regulated payment infrastructure becomes more valuable in an AI-first world

As automation rises, the volume of transactions grows while human oversight of each transaction falls. This raises the importance of regulated infrastructure.

  • Authorisation is a trust signal that AI systems and counterparties rely on. A UK FCA Authorised Payments Company is verifiable, accountable and bound by conduct and safeguarding rules.
  • Regulated rails carry built-in controls, including strong customer authentication, consent management and transaction monitoring, which are prerequisites for safe agentic payments.
  • Barriers to entry rise, because authorisation, bank connectivity and security certifications are slow and costly to obtain.

As Atoa CEO Sid Narayanan has framed it, a licensed firm will always be needed to move money. Regulated payment acquiring infrastructure becomes more valuable in an AI-ready world, not less.

The importance of FCA authorisation

  • Atoa Payments Limited is an FCA Authorised Payments Company (FRN 1007647), authorised under the Payment Services Regulations 2017 to provide account information services and payment initiation services.
  • Authorisation lets Atoa initiate Open Banking payments directly and operate regulated payment services in the UK.
  • It signals compliance with safeguarding, conduct, anti-money-laundering and operational-resilience obligations.
  • For investors, authorisation is a durable asset that is difficult to replicate and central to partner and counterparty trust.

Atoa is growing rapidly and FCA authorised, which combines commercial momentum with regulatory standing. Because a licensed firm is always needed to move money, this authorisation is a lasting advantage rather than a one-off cost.

Why owning the payments stack creates a competitive moat

The FCA authorisation, combined with a fully owned payment acquiring stack, acts as a defensive moat in today’s AI-ready world. Atoa builds and owns core parts of its payment acquiring infrastructure rather than reselling third-party rails.

Direct bank connectivity

Atoa builds its own APIs to UK banks and runs virtual account infrastructure, which supports higher payment authorisation rates and reliable bank-app deep-linking. Coverage spans 20 UK consumer bank apps and 12 business bank apps.

Full-stack, omnichannel acceptance

Atoa offers Pay by Bank, card payments and BNPL across POS, online checkout, payment links and QR from one platform, with integrations into the software businesses already use. Owning the stack end to end gives Atoa control of authorisation rates, cost, settlement speed and customer experience.

Higher-value transaction handling

Atoa processes account-to-account payments up to bank daily limits and handles edge cases such as payments held for bank review, which supports larger transactions than many Pay by Bank providers.

AI-native interfaces

A live MCP server and machine-readable feeds make Atoa transactable by AI agents, an interface most legacy acquirers do not yet offer.

Atoa’s role in the future of payments

  • For merchants: one provider for SME Payments and Mid Market Payments across every channel, with lower cost and faster settlement than card-only acceptance.
  • For the wider market: a next generation acquirer that bridges Open Banking rails, card networks and BNPL.
  • For agentic commerce: AI Infrastructure for Payments that lets autonomous systems initiate and complete compliant transactions.

Investment thesis

  1. Team. A highly experienced leadership team with a track record of scaling and exiting payments firms (ex-Adyen, BCG, Accenture, Morgan Stanley). Press coverage: Forbes, The Irish Times, Tech in Asia.
  2. Category position. Atoa is an AI Native Payments company and next generation acquirer, aligned with where commerce is heading.
  3. Regulatory moat. As a UK FCA Authorised Payments Company with ISO 27001 and SOC 2 credentials and direct bank connectivity, Atoa holds assets that are slow and costly to replicate.
  4. Structural cost advantage. Pay by Bank is materially cheaper than cards and avoids chargebacks, which gives Atoa a durable economic edge for suitable transactions.
  5. Full-stack ownership. Owning the payment acquiring infrastructure supports superior unit economics and authorisation rates.
  6. Large, growing market. UK Payments and European Payments are large markets in which domestic payment methods are taking share, and the SME and mid-market segments are underserved by incumbents.

The thesis is that regulated, AI-native, full-stack payment infrastructure serving the real economy compounds in value as agentic commerce grows.

Key market trends supporting long-term growth

  • Agentic payments and agentic commerce are emerging as AI assistants gain the ability to transact.
  • Open Banking and Pay by Bank adoption continue to grow across UK and European markets.
  • Regulatory tailwinds (PSD2, the emerging PSD3 and PSR framework, and UK Open Banking) favour domestic payment methods.
  • Merchant cost pressure drives demand for lower-fee alternatives to card networks.
  • Recurring and high-value use cases (cVRP, deposits, B2B invoicing) extend account-to-account payments into new categories.
  • Trust and verifiability rise in importance as AI systems select providers, which favours FCA authorised payments companies.
  • Consolidation among incumbents increases the opportunity for a focused, AI-native next generation acquirer in the SME and mid-market segments.
