AppZen

AppZen builds AI agents for finance teams that automate accounts payable, audit expense reports and check corporate card spend. It is used by large enterprises that want every transaction reviewed for fraud and policy breaches instead of sampling a few.

Products cover autonomous AP, an AI-managed AP inbox, e-invoicing compliance, expense audit, VAT reclaim and card audit for non-T&E transactions. The models are trained on enterprise spend data and keep an audit trail for each decision, and AppZen has released finance-specific language models under the ZenLM name.

The Mastermind platform adds a low-code AI Agent Studio, prebuilt apps and analytics for finance operations. Integrations connect AppZen to existing ERP, expense and card systems, and customers such as Intuit use it to audit all of their spend.
