The AIF demands detailsthey forgot.

Clients speak in features. HMRC demands "uncertainties".
We bridge the gap by forensically extracting the evidence from their git history.

HMRC's new standard is forensic.

The Additional Information Form (AIF) ended the era of generic narratives. Advisors now face three structural risks that manual interviews cannot solve.

Algorithmic Scrutiny

HMRC now deploys automated risk profiling. Narratives containing boilerplate phrasing or lacking specific technical details are flagged instantly. "Agile development" is no longer an explanation.

Evidence Decay

Retrospective interviews are fundamentally flawed. By year-end, engineers have forgotten the specific concurrency issues or algorithm failures that prove the claim. You are left with vague recollections.

The Technical Gap

Your clients optimize for shipping features. The tax code rewards technical failure. Bridging this semantic gap manually requires hours of senior partner time per claim.

Forensic extraction.
Zero interviews.

We don't write generic descriptions. We extract the exact technical hurdles your client faced directly from their engineering logs.

What We Analyze

  • Git History (Commits & Diffs)

    We spot "churn" and "refactors" that signal uncertainty.

  • Issue Tracking (Jira/Linear)

    We identify tickets labeled "Bug", "Performance", or "Blocked".

  • Pull Request Reviews

    We read developer discussions debating technical approaches.

Zero friction for your client.

Eliminate the bottleneck of chasing engineers for documentation.The entire process is automated, secure, and completed in minutes.

STEP 01

Invite Client

Send a secure magic link to the CTO. No accounts to create, no passwords to manage.

STEP 02

Connect Repo

Client authorizes read-only access to their git provider (GitHub/GitLab) in two clicks.

STEP 03

Receive Draft

We analyze the commit history and generate a forensic, audit-ready AIF draft.

Compliance Protocols

Model Safety

Strictly Factual

Our models are constrained to evidence found in git logs. They cannot generate claims without a linked commit hash.

Data Privacy

Ephemeral Processing

We process code in-memory to extract metadata. Source code is never persisted to disk and is discarded immediately after analysis.

Governance

Advisor Controlled

You retain full editorial control. Review evidence links, edit narratives, and approve the final output before it touches a tax form.

Partner with us.

We are looking for a small number of pilot partners to shape the future of automated R&D claims.

If you have a client with complex tech and poor documentation, let's fix it together.
