Ingest. Analyze. Seal. HammerLedger turns source material into a defensible evidence chain — cryptographically traceable from claim back to source. Live today for R&D tax credits and PCI compliance. Built for every regulated decision tomorrow.
How It Works
A single workspace where every file, finding, and claim traces back to its source — with full provenance at every step.
Create a ledger. Drag and drop your source files — code, documents, emails, PDFs, spreadsheets. Every file is hashed and timestamped at intake.
AI analyzes every file against your use case — R&D activity, PCI control evidence, or any regulated workflow. Findings carry model attribution and confidence scores.
Review AI findings. Your technical lead and financial officer sign off to confirm accuracy. Every claim traces to specific files and paragraphs.
The ledger is cryptographically sealed with a Merkle root hash. Tamper-proof evidence that your documentation existed at this point in time.
Platform Features
SHA-256 hashing on every file. Merkle-style sealing combines all evidence into a single root hash. Any change — even one character — breaks the seal.
Every claim in your report traces back to the exact file, page, and paragraph. Neo4j knowledge graph maps relationships between evidence, findings, and claims.
Per-file deep analysis identifies R&D activities, maps technologies and components, and scores evidence quality — with human oversight at every step.
Direct for companies filing their own claim, or multi-client for accountants and advisory firms. Invite reviewers, assign roles, control who sees what.
Catch issues before the auditor does. Simulated CRA review flags weak evidence, missing documentation, and inconsistencies in your claim.
Generate evidence-linked T661 claim sections. Technological uncertainties paired with proof of experimentation, all traceable to source files.
Who It's For
Stop handing 15–25% of your R&D credit to a specialist. Capture evidence at the source. Your existing accountant files with confidence.
Stop referring R&D and compliance files out to specialists. Keep them in your firm — file confidently with a cryptographically-sealed chain of custody attached.
Under audit, in litigation, or facing regulatory scrutiny — you need to show your work. Immutably. Across R&D, PCI, and every regulated workflow.
