Our mission is to increase the GDP of the internet and we have a staggering amount of work ahead. That means you have an unprecedented opportunity to put the global economy within everyones reach while doing the most important work of your career.
Machine Learning at Stripe
Machine learning is an integral part of almost every service at Stripe. Key products and usecases powered by ML at Stripe include merchant and transaction risk payments optimization and personalization identity verification and merchant data analytics and insights. We are also using the latest generative AI technologies to reimagine product experiences and are developing AI Assistants both for our customers and to make Stripes more productive across Support Marketing Sales and Engineering roles within the company.
Stripe handles over $1T in payments volume per year which is roughly 1 of the worlds GDP. We process petabytes of financial data using our ML platform to build features train models and deploy them to production. We use a combination of highly scalable and explainable models such as linear/logistic regression and random forests along with the latest deep neural networks from transformers to LLMs. Some of our latest innovations have been around figuring out how best to bring transformers and LLMs to improve existing models and enable entirely new product ideas that are only made possible by GenAI. Stripes ML models serve millions of users daily and reduce financial risk increase payment success rate and grow the GDP of the internet. We work on challenging problems with large business impact and seek to foster creativity and innovation.
About the team
Stripe Capital provides access to fast flexible financing to smallandmedium businesses on Stripe to accelerate their growth and we lent over $1B in 2024. Businesses use the funds for marketing team growth geographic expansion working capital new equipment purchases and much more.
Machine learning is core to Stripe Capitals businesswe use information about businesses from their activity within and outside of Stripe and our models to automatically underwrite uniquely tailored financing offers to their needs which banks are often unable to do. We are doing so through models with an established performance history data infrastructure that is Stripe scale and a strong feedback loop that includes explainability anomaly detection and a risk portfolio management layer. Were an endtoend team going from ideas to models to shipping in production.
