Ingest your client's data. Understand the research. Connect the evidence. Produce audit-defensible R&D tax credit reports with full traceability — cryptographically sealed.
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 client's files — source code, documents, emails, PDFs, spreadsheets. Every file is hashed and timestamped at intake.
AI analyzes every file for R&D activities, technological uncertainties, and systematic experimentation. Component and technology mapping with confidence scoring.
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.
Works for consultants managing multiple clients and for companies filing directly. 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
When your client says "we did R&D" — prove it. Every claim in your report traces to the exact source file and paragraph.
