Zapata Quantum

Zapata Quantum, Inc. (OTCQB: ZPTA) is a Boston-based, publicly traded, hardware-agnostic quantum software company. Its Quantum Application Intelligence platform spans the full lifecycle of quantum application development, covering use-case identification and problem evaluation, algorithm and logical circuit design, and hardware execution, compilation, resource estimation, and benchmarking on real quantum machines. It is the only participant across all technical areas of DARPA's Quantum Benchmarking program and has worked with Fortune 500 enterprises including BP, BMW, BASF, BBVA, and Sumitomo Trust. The company completed a year-long restructuring in April 2026 with an oversubscribed $15 million Series D financing led by Triatomic Capital, having resolved $18.7 million of debt and preserved a portfolio of more than 60 patents.

The only public pure-play quantum software company, hardware-agnostic across all three layers of the stack (use case, algorithm, and hardware execution) rather than tied to one machine, backed by 60-plus patents and full-coverage participation in DARPA's Quantum Benchmarking program.
