Mastercard’s SVP of Global Products on How to Enter New Markets

Expanding internationally is more complex than ever, with economic uncertainty, shifting regulations, and unpredictable tariffs creating constant challenges. While overseas opportunities can be tempting, businesses must navigate a landscape full of blind spots and evolving risks that demand careful planning and adaptability.

Simone Tamussin, SVP of Product Management at Mastercard Gateway, shares valuable insights from his experience working with companies facing these hurdles. He discusses common pitfalls growth-focused leaders encounter, proactive strategies for entering new markets safely, and practical tips for managing the overwhelming paperwork that comes with global expansion.

Interview Highlights

  • Common Pitfalls in Global Expansion [01:22]
    • Leaders often assume global success translates easily into new markets, leading to missteps.
    • A failed market entry occurred due to underestimating local payment infrastructure requirements.
    • Assumed global payment standards (e.g., Visa, Mastercard) would apply, but local systems were significantly different.
    • The oversight caused delays, high costs, and ultimately, customer loss.
    • Regulatory and technological standards also vary; what works in one country may be non-compliant elsewhere.
    • Pushing foreign best practices on local regulators often backfires.
  • Navigating Regulatory and Technological Hurdles [03:43]
    • Scaling into new regions involves complex and evolving risks.
    • Key risk factors include technological readiness, regulatory environment, and data governance.
    • Nationalism and localization trends can create resistance to foreign products and data transfer.
    • Economic pressures, tariffs, and global dynamics can rapidly shift market conditions.
    • Past assumptions may become obsolete quickly; constant monitoring is essential.
    • A dedicated, multidisciplinary team is needed to anticipate country-specific challenges.
  • Strategic Partnerships and Compliance [05:35]
    • Flexibility and adaptability are key when entering heavily regulated markets.
    • Partnering with local players—even competitors—can ease market entry.
    • Business models may need to be adjusted for specific regional conditions.
    • Invest in legal, regulatory, and data privacy expertise early in the process.
    • Conduct thorough risk assessments to evaluate current and future regulatory impacts.
    • Monitor political and regulatory shifts that could quickly alter the business landscape.
    • Partnering with local competitors can ease entry into regulated markets.
    • Local partners may have existing integrations, regulatory relationships, and market access.
    • Collaborating with such players helps navigate complex infrastructure and compliance needs.
    • Large companies can offer “compliance as a service” to smaller firms lacking resources.
    • Even competitors can benefit from mutual support in different markets based on strategic alignment.
  • Key Mistakes When Scaling Internationally (for Startups) [09:37]
    • Startups often underestimate compliance, delaying it in favor of rapid growth.
    • This can backfire if regulations change unexpectedly, disrupting operations.
    • Entering a new market means integrating into the local ecosystem, not just launching a product.
    • Gathering local intel and understanding the regulatory landscape is crucial.
    • Agile startups can gain an edge by being faster and more adaptable than incumbents.
    • Compliance should be seen as a strategic advantage, not a secondary concern.
    • Compliance-as-a-service can be a valuable strategy for startups and smaller enterprises.
    • Similar to banking-as-a-service or embedded finance, it helps businesses scale by offloading regulatory burdens.
    • Identifying reliable and trusted partners is key to managing compliance effectively.
    • This allows companies to focus on their core strengths while staying protected from regulatory risks.

From a startup perspective, if you are agile and nimble, able to address compliance while improving inefficiencies that incumbents have, you can turn that into an opportunity. You cover compliance, adapt to regulatory changes, and move faster than most incumbents. Use that to your advantage, but don’t underestimate some components of it.

  • Leveraging AI for Geopolitical and Regulatory Research [12:19]
    • Large language models (LLMs) are useful for initial geopolitical and regulatory research, especially for startups prioritizing market entry.
    • They help map threats and identify where deeper local investment is needed.
    • LLMs can process vast volumes of regulatory documents and mandates efficiently.
    • This supports faster impact analysis on systems, products, and customers.
    • Human expertise combining tech, business, and legal knowledge is rare and hard to scale.
    • LLMs can help preserve institutional knowledge and reduce reliance on individual experts.
    • Regulatory changes often come with short implementation deadlines (e.g., 4–6 months).
    • Delays in processing mandates can hinder timely compliance.
    • LLMs can help speed up initial analysis, but outputs must be carefully validated.
    • Relying solely on LLMs without proper checks risks serious compliance failures.
    • Ensuring accuracy in LLM outputs for complex, nuanced regulations is challenging.
    • The process involves continuous training, review, and refinement of the models.
    • Better to over-implement than risk missing critical compliance requirements.
    • Human supervision and quality checks remain essential.
    • LLMs can accelerate work but do not replace expert oversight.

It’s almost better to implement something that may not be needed than to skip it and then be hit by a compliance regulator that stops you from doing business. So focus on those areas. Is it right? If it’s wrong, retrain the model, continue, and apply quality checks. You will always need supervision from a human point of view.

  • Aligning Cross-Functional Teams in a Global Market [18:02]
    • Aligning cross-functional teams requires educating them on local market dynamics and regulatory differences.
    • Training and cross-functional collaboration help teams understand the need for flexibility and adaptability.
    • Identify common scalable factors while allowing tailored implementations per country or region.
    • Local partnerships are crucial for navigating regulatory and market-specific nuances.
    • Continuous communication, cross-training, and knowledge sharing improve alignment.
    • Avoid assuming one solution fits all markets; customization is essential to avoid failure.
  • Scaling Internationally: Collaboration & Cultural Awareness [19:49]
    • Exercise an abundance of caution when working across global teams and markets.
    • Cultural differences impact communication and setting objectives.
    • Collaborating and co-creating with local rule-makers can ease market entry.
    • Building strong relationships with key domestic players improves relevance and influence.
    • Partnering with trusted local entities facilitates scaling and compliance.
    • Scaling is complex and requires new leadership mindsets.
    • Old processes emphasizing heavy standardization and bureaucracy no longer work.
    • Long-term, rigid planning frameworks are impractical due to rapid changes.
    • Products must be embedded in local systems, not just deployed globally.
    • Technology and processes need flexibility to adapt by region.
    • Teams can be regional or centralized but must adjust approaches per market needs.
