<p><strong>ABOUT BASELAYER</strong></p> <hr> <p>Every business in America needs a bank account to exist. The system that decides whether they're real, who's behind them, and whether they're a risk, runs on infrastructure from the 1980s. We're rebuilding that layer from scratch.</p> <p>Baselayer is the identity layer for institutions across the United States — the most complete business graph in America and every human tied to it. We fuse public records, IRS data, sanctions lists, web signals, and fraud telemetry from 2,200+ financial institutions into a single graph that resolves any business and the humans behind it in milliseconds. The legacy credit bureaus took 50 years to build something that gets 60% match rates. We've built something that gets 98% in under two years.</p> <p>Today we're trusted by over 20% of financial institutions in America — including FIS, Rho, Socure and leading loan infrastructure providers. But the graph is becoming infrastructure for anyone who needs to know if a business is real and worth trusting: gig platforms, marketplaces, AI companies, and commerce infrastructure at scale.</p> <p>Trust is the substrate of every financial transaction. We're rebuilding it.</p> <p><strong>ABOUT THE TEAM</strong></p> <hr> <p>We're solving real-time entity resolution at a scale no one else has cracked — fusing dozens of data sources into a single business identity graph and resolving any entity in milliseconds. It's a graph AI problem, a retrieval problem, and a fraud-modeling problem stacked on top of each other. The technical depth is real.</p> <p>You'd be joining a small team where the data moat is defensible, the research problems are open, and the infrastructure you build becomes load-bearing for businesses. Ownership is real. Velocity is real. There's no layer of process between an idea and shipping it.</p> <p>We're at an inflection point — the graph is built, the match rates speak for themselves, and the hardest problems are still ahead: graph embeddings, fraud propagation models across the business network, real-time traversal at sub-100ms latency, and expanding the identity layer beyond finance into every platform that needs to trust a business.</p> <p>If you want to work on something foundational — the kind of infrastructure that gets built once and everything else runs on top of — this is it.</p> <p><strong>ABOUT THE ROLE</strong></p> <hr> <p>Baselayer is building the most comprehensive, accurate, and continuously-current identity graph of US businesses — fusing public records, IRS data, sanctions lists, web signals, and fraud telemetry from thousands of financial institutions into a single graph that resolves any business in milliseconds. None of that works without world-class data infr
