What is TigerBeetle?

TigerBeetle is a database built from scratch for one use case: double-entry accounting ledgers. It offers deterministic simulation testing, Direct I/O, and benchmarks showing millions of financial transactions per second. Designed by engineers burned by building ledgers on top of general-purpose databases. Used by fintechs, payment processors, and neobanks who need guaranteed correctness on money-movement workloads.
