FINTEX Exclusive Interview with Marc-Alexander Christen, CEO of SumUp

Summary: SumUp — company, products, history and vision

SumUp is a global payments company delivering end‑to‑end merchant solutions that cover in‑person and online card acceptance, online payments, and embedded finance capabilities. Led by CEO and co‑founder Marc‑Alexander Christen, SumUp has evolved from a standalone card‑reader provider into a broad payments platform that includes issuing services via partner banks, SEPA and instant payment capabilities, PIS/AIS interfaces, multi‑currency wallets, FX, onboarding and KYB/KYC tooling, fraud and AML controls, and an expanding open banking/open finance footprint. The company maintains a regulated, compliance‑minded approach and pursues partnerships with banks and licensed PSPs (payment institutions, EMI, acquiring entities) to operate within European and global markets. SumUp emphasizes a product‑driven, risk‑aware, platform‑level mindset aimed at serving marketplaces, SaaS platforms, platforms with embedded finance needs, crypto VASPs in compliant contexts, and other partner ecosystems such as affiliates and certain regulated verticals. The long‑term view centers on expanding SEPA Instant coverage, strengthening open banking capabilities, broadening card and wallet offerings, and scaling cross‑border, embedded finance use cases for partners and merchants of all sizes.

Key product pillars include IBAN issuance via partner banking rails, SEPA SCT Inst routing, PIS/AIS access for programmable payments, card programs (physical and virtual), multi‑currency wallets and FX, onboarding with robust KYB/KYC and risk tooling, fraud/AML controls, and embedded finance components integrated into partner platforms. SumUp’s strategy combines direct product development with strategic licensing and network partnerships to maintain a scalable, compliant model that can adapt to evolving regulatory regimes, including MiCA considerations in crypto‑related and digital asset contexts. The company positions itself against well‑established platforms by emphasizing openness through APIs, developer‑friendly tooling, and a modular suite that supports marketplaces, SaaS providers, and platform ecosystems seeking a compliant payments and embedded finance backbone.

Q&A with Marc‑Alexander Christen, CEO of SumUp

Q1: Tell us about your background and your current role at SumUp.

A: I’m a co‑founder and CEO of SumUp, leading the company since its inception. My focus is on setting the strategic direction, ensuring regulatory alignment across markets, and driving product‑led growth that helps merchants and platform partners scale payments and embedded finance capabilities. I oversee governance, risk management, and partnerships with banks and licensed PSPs that enable our multi‑jurisdictional footprint, while fostering a product culture that emphasizes reliability, security, and customer value.

Q2: How would you describe SumUp’s current regulatory setup and licensing approach?

A: SumUp operates in a regulated payments environment across multiple markets. We leverage a combination of local acquiring arrangements, payment institution (PI) licenses, and electronic money (EMI) frameworks through a network of licensed partners and directly where permitted. Our approach emphasizes compliance by design, with robust KYB/KYC, AML controls, transaction monitoring, and governance that aligns with EU PSD2 expectations and local requirements. We explore MiCA‑related governance where crypto and tokenized assets intersect with our embedded finance capabilities, and we maintain a flexible, partner‑led structure to ensure license viability in each market.

Q3: What are SumUp’s core products today, and how do they fit together for a merchant or platform partner?

A: Core products span several layers:
– IBAN issuance and account rails through partner banks, enabling merchant settlement and business banking workflows.
– SEPA payments, including SCT Inst for near‑real‑time euro transfers, with routing logic that favors instant rails where available.
– PIS/AIS access for programmable payments and data access under PSD2.
– Card programs (physical and virtual), wallets, and multi‑currency capabilities with FX tooling.
– Onboarding, KYB/KYC, and ongoing risk management, including fraud and AML tools.
– Embedded finance modules (e.g., payments, wallets, and financial rails embedded in partner platforms).
– Acquiring and payment processing across card schemes, with a market‑scaled processing backbone.
The stack is designed to be modular: partners and merchants can mix and match rails—payments, wallets, Open Banking, card issuance, and embedded finance—through APIs, dashboards, and sandbox environments to suit their business models.

Q4: Who are SumUp’s typical target clients and what use cases do you see most often?

A: Our targets include marketplaces, SaaS platforms, marketplaces with embedded payments, and platform ecosystems that require a scalable payments metalayer. Use cases span in‑person and online card acceptance, vendor onboarding via IBAN/account rails, payouts to sellers or affiliates, merchant cash flow via wallets and FX, and embedded finance experiences inside partner apps. We also engage with crypto‑related VASPs and regulated affiliates where permitted, applying stringent risk controls. We tailor solutions for small businesses and mid‑market platforms that need reliable, compliant payments with flexible onboarding and strong risk management.

Q5: How would you describe SumUp’s risk appetite and compliance approach?

A: We operate with a prudent risk framework that balances growth with compliance. This means rigorous KYB/KYC, continuous transaction monitoring, real‑time fraud detection, and robust AML controls. Our licensing and partner structure enable us to meet local regulatory requirements while maintaining a scalable, product‑led approach. We continuously assess risk by market and vertical, applying appropriate screening, data protection, and governance to protect merchants and users while enabling legitimate business models, including regulated use cases that require additional controls.

Q6: SEPA Instant coverage and routing logic—how does SumUp handle it?

A: We aim to route payments via SCT Inst where the rails are available, delivering near‑real‑time settlement for euro transactions. When SCT Inst isn’t available in a given corridor or merchant currency, we fall back to standard SEPA transfers or other supported rails, ensuring reliable settlement while optimizing for speed and cost. Our routing logic is driven by routing rules, regulatory constraints, and partner bank capabilities, with the goal of offering the fastest viable settlement option to merchants and platform partners.

Q7: What Open Banking capabilities do you offer?

A: Our Open Banking toolbox includes access to PIS (payments initiation) and AIS (account information) APIs under PSD2 frameworks, enabling programmable payments and rich dataset access for reconciliation, risk scoring, and platform‑level analytics. We provide developer tools, sandbox environments, and webhook notifications to keep partner platforms synchronized with payment events and account data as regulations allow and markets enable.

Q8: Do you hold acquiring licenses directly, or do you rely on partners?

A: We operate through a mix of direct licensing where allowed and strategic partnerships with licensed banks and PSPs. This hybrid approach enables broad market access while maintaining compliance and governance. In some markets, local acquiring arrangements are essential to optimize card acceptance and settlement processing, and we continuously evaluate the most efficient license structure per jurisdiction.

Q9: Onboarding timelines—what can a new merchant or platform expect?

A: Initial onboarding for a straightforward merchant profile typically ranges from a few days to two weeks, depending on data completeness, risk assessment, and KYC requirements. For higher‑risk verticals or large platform integrations, onboarding can extend to a few weeks. We provide a clear checklist: business registration documents, beneficial ownership information, financial statements (where applicable), business model details, and a description of typical settlement flows and use cases.

Q10: What is the tech stack like—APIs, webhooks, dashboards, sandbox?

A: We offer modern REST/SDK‑driven APIs with comprehensive documentation, event‑driven webhooks, and a developer dashboard for sandbox and live environments. Our sandbox mirrors production data models to streamline integration testing, and we provide sample code, client libraries, and integration guides to accelerate time‑to‑value for partners and merchants.

Q11: How is pricing structured at a high level?

A: Our pricing follows a merchant‑friendly model that typically combines a per‑transaction basis (card processing) with a fixed fee per settlement event and optional value‑add services (onboarding, KYC checks, FX, and wallet features). Rates generally reflect interchange‑plus or blended structures with transparent components, designed to be competitive versus major PSPs while aligning with the depth of features used by the merchant or platform. Exact numbers vary by market, vertical, and risk profile, and customers receive a clear quote with no hidden fees for core rails.

Q12: How does SumUp position itself against Stripe, Adyen, Banking Circle, Swan, and Lemonway?

A: We compete on a modular, platform‑friendly approach, emphasizing embedded finance capabilities, multi‑rail payment processing, and a governance‑driven regulatory model that supports partner ecosystems. Our differentiators include strong KYC/AML tooling, flexible routing for local and instant rails, and broad access to open banking and card programs via partnerships. While Stripe, Adyen, and others are formidable platforms, SumUp emphasizes product enablement for partner ecosystems, with clear focus on embedded payments, access to local rails, and a compliant, scalable architecture that can adapt to regulated use cases in various jurisdictions.

Q13: What is on the 12–24 month roadmap and the long‑term vision?

A: In the near term, we plan to expand SEPA Instant coverage and routing, deepen Open Banking capabilities, broaden card issuance and wallet tooling, and scale cross‑border payment rails through partnerships. We also expect to continue enhancing onboarding automation, KYB/KYC optimization, and risk tools, while enabling more embedded finance use cases for platform partners. Long‑term, the vision includes deeper embedded finance rails, broader crypto‑adjacent capabilities under MiCA‑friendly governance, and a platform that enables merchants and ecosystem partners to compose payments and financial services with minimal integration friction, all in a compliant, secure environment.

Q14: How does SumUp approach crypto or crypto‑adjacent services and VASP partnerships?

A: We assess crypto‑adjacent opportunities within a clearly defined regulatory framework. Our approach focuses on compliant interfaces, custody considerations, and risk controls aligned with MiCA‑like regimes in relevant markets. Any crypto or tokenized service would be offered through carefully structured partnerships and governance that ensure compliance, consumer protections, and risk management consistent with the rest of our payments rails.

Q15: How do you support regulated verticals like adult or affiliate programs?

A: We evaluate each vertical against our risk framework and regulatory exposure on a case‑by‑case basis. In regulated contexts, we apply enhanced KYC, ongoing monitoring, and tailored risk controls. When allowed, we provide the same platform capabilities—payments rails, onboarding, and anti‑fraud tooling—with additional safeguards to protect both the merchant and the platform ecosystem.

Q16: What about acquiring and processing—how do you handle cross‑border payments?

A: We rely on a network of acquiring partners and processing engines that support cross‑border card acceptance and settlement. Our architecture is designed to optimize routing, settlement currencies, and local compliance requirements. We continuously assess the most efficient paths for merchants in different markets, balancing speed, cost, and regulatory compliance.

Q17: How do you enable marketplaces and SaaS platforms to integrate with SumUp?

A: We provide developer APIs, webhooks, and a dedicated partner program with sandbox access, documentation, and reference implementations. This enables marketplaces and SaaS platforms to embed payments, open banking capabilities, and wallet features directly into their product workflows, including onboarding, settlement, and payout flows to sellers or affiliates.

Q18: How do you ensure data privacy and security across rails?

A: We implement robust data protection, encryption in transit and at rest, access controls, and continuous monitoring. Our risk and compliance teams work with engineering to adhere to regional data protection laws and payment security standards, while our architecture supports identifiable and pseudonymous data handling as required by market and product use cases.

Q19: What does success look like for SumUp in the partner ecosystem?

A: Success means scalable, compliant rails that empower partners to rapidly embed payments and financial services into their products with low integration effort and clear risk controls. It also means delivering reliable settlement, fast onboarding, strong fraud protections, and a platform that can evolve with regulatory changes while maintaining a superior merchant and user experience.

Q20: What should potential partners know about onboarding speed and required documentation?

A: Prospective partners should prepare corporate documentation (entity registration, ownership structure), business model details, anticipated payment flows, and a description of typical use cases. Timelines depend on the complexity of the integration and risk profile, but a well‑prepared submission typically leads to a streamlined onboarding process with clear milestones and point‑of‑contact support.

Q21: How do you communicate with customers and merchants during onboarding and after go‑live?

A: We maintain dedicated partner success teams, provide clear documentation, and offer dashboards for monitoring, reconciliation, and analytics. Ongoing communication includes product updates, risk reviews, and support channels designed to resolve issues quickly and keep merchants compliant and informed.

Q22: If a merchant or platform wants to start a conversation with SumUp, what should they do?

A: They should reach out through SumUp’s partner program channels or contact our merchant sales team to discuss use cases, rails, and integration requirements. We tailor proposals to fit the merchant’s business model, technical capabilities, and regulatory constraints, with a clear plan for onboarding, risk management, and scalability.
