Value proposition
Makes money programmable. Every transaction is checked with double-entry accounting (debit, credit, match) before it executes. This lets AI agents and engineering teams automate billing, payments, reconciliation and close without balance errors.
Products and solutions
Ledgers (configurable-schema, strongly consistent double-entry ledger API), Payments (move and track money in one API call), Recon (turns bank files, invoices, docs and code into reconciled financial objects), Typesafe schema-generated SDKs, FRAGMENT MCP server so agents can read and write payments, Roles & Permissions, multi-currency and custom currencies, reporting and S3 export, AWS regional deployments
Unique value
The control plane for financial code. The agent decides what to do, and Fragment's ledger enforces financial correctness, so every transfer is balanced and every balance is correct.
Target customer
Fintechs, vertical AI/SaaS companies, marketplaces, brokers and platforms that need to track customer balances and money movement. Primarily engineering and finance teams building agent-driven financial workflows.
Industries served
Fintech, Healthcare (patient billing, claims reconciliation), Logistics (fuel cards, driver payouts), Insurance, Marketplaces, Spend management, Retirement and wealth, Energy, Education
Technology advantage
A double-entry ledger built for engineers, with schema-as-code fund-flow modeling. It adds strong consistency, low-latency balance reads and high-throughput writes, entry conditions for authorizing transactions from the ledger, schema-generated typesafe SDKs, and native MCP integration for AI agents. The company is SOC 2 and HIPAA certified.
How they differentiate
Unlike Modern Treasury, which is payment-operations-led, or low-level ledger databases like TigerBeetle and Formance, Fragment pairs an engineer-friendly ledger with fund-flow schema design, payments and reconciliation. It has repositioned as agent-native financial infrastructure, using MCP and ledger-enforced guardrails so AI agents cannot mishandle money.
