By connecting employees to over 1,000 internal tools and skills, it enables secure, enterprise-scale productivity across the organization. Authors: Anna Mason, Sharadh Krishnamurthy, Anupam Upadhyay Topics: Engineering AI Read 2026.7.16 How Stripe uses graph search and state machines to auto-remediate a global database fleet Summary: Discover how we modeled our MongoDB infrastructure as a traversable graph and then use pathfinding algorithms to dynamically compute and execute recovery plans. This automated approach reduced pager volume by 30% (~200 pages/year), eliminated 12 days of unhealthy shard states annually, and supports new shard layouts with zero manual effort. Authors: Pragya Mehta, Sai Samant Topic: Engineering Read 2026.6.22 Extending Stripe’s network with stablecoins Summary: Most of the world's money still moves in batches. A wire submitted at 2pm might settle by end of day, if you made the cutoff. ACH takes one to three business days. Cross-border payments touch correspondent banks, each adding lag and a fee. Stripe has spent over a decade building the Global Payments and Treasury Network (GPTN), a programmable infrastructure for global money movement that batches transfers to reduce cost, nets opposing flows to minimize actual cash moved, and routes through the optimal path between accounts. Under the hood, it's a graph with accounts as nodes, and payment rails as edges.
