About Aplazo

Aplazo, a Mexican BNPL startup, offers a unique solution for an underbanked Population. Unlike its international counterparts, Aplazo isn't just about debt - it's an alternative to cash for many Mexicans. Founded four years ago, Aplazo allows users to make fractionated payments online and in stores, even without a credit card. We are on a mission to unlock financial access, freedom, and opportunity for every Mexican. Now our users can have what they want and when they want. Aplazo allows its consumers to live their ideal lifestyle, making it easier to acquire the products they want. Through our platform, consumers can split their online and offline purchases into multiple installments without needing a credit card and avoiding the debt trap.

In-store transactions account for more than half of Aplazo's business, highlighting the limited reach of e-commerce in Mexico. Aplazo's success is attributed to its focus on data and technology. By leveraging AI, the company has been able to limit credit loss despite its rapid growth. Notably, 40% of Aplazo's users have no credit history, making traditional credit checks irrelevant. This is a major hurdle for international BNPL players who may struggle in the Mexican market.

Aplazo has recently received Series B funding of $70 Million USD and Series A+ funding of $27.5 Million USD in 2022 With a total of $110 million raised Aplazo is well-positioned for continued growth and innovation in the Mexican fintech landscape and its team is growing in each vertical. We are setting out to make an impact on an epic scale. Aplazo enables merchants to connect with consumers in a creative, purposeful way, building more loyalty and trust between them. Aplazo's integrated, tech-enabled platform offers merchants the ability to increase average basket size, conversion, and customer engagement.

About ML & AI Labs

At Aplazo, our ML & AI team is a cornerstone of our technological innovation and strategic decision-making. We pride ourselves on our technical maturity and high proficiency in addressing complex and critical business challenges. Our team is dedicated to solving high-stakes problems across various domains, including risk and payments, merchants, B2C, personalisation, growth and marketing, recommendation systems, customer support, collections, underwriting, credit life cycle management, and fraud detection.

Aplazo ML & AI lab has been instrumental in the development of state-of-the-art credit risk and fraud detection models. The risk and payment machine learning models suite has leveraged advanced data science and AI algorithms to achieve best-in-class prediction capabilities. Aplazo has adopted best practices in MLOps, creating a seamless workflow for model development, deployment, and monitoring. This includes automated CI/CD pipelines, version control for models and data, and robust monitoring and logging systems. We have built a sophisticated ML engineering infrastructure that supports scalable model training, testing, and deployment. This infrastructure ensures the high availability, reliability, and performance of our machine learning solutions.

Our expertise in developing advanced recommendation models has significantly enhanced user engagement, driving more personalised and meaningful interactions with our platform. We have also created sophisticated propensity and activation probability models, enabling us to optimise Customer Acquisition Cost (CAC) effectively. These models help us target the right customers with the right offers at the right time, maximising our marketing efficiency.

Moreover, we have engineered cutting-edge data science tools to deepen our understanding of the relationships within our consumer base. These insights have been instrumental in refining our referral programs, leading to increased customer retention and satisfaction. Our commitment to leveraging data science for continuous improvement and innovation ensures that Aplazo remains at the forefront of delivering exceptional value to our customers and stakeholders.
