Evidence first
Findings retain source-file and source-row lineage so reviewers can see where the numbers came from.
Screen target companies at scale. Follow the evidence. Decide what deserves a closer look.

Addback is Finsider's free pre-QoE screening layer, built to help deal teams decide whether a target merits deeper financial diligence.

Findings retain source-file and source-row lineage so reviewers can see where the numbers came from.
Start with an initial financial screen before committing resources to a full diligence engagement.
Apply a consistent set of ten checks across target companies, while keeping each company's evidence and limitations distinct.
Unsupported evidence is marked not assessable, not silently estimated. Candidate adjustments remain candidates for professional review.
Diligence workflow
Addback organizes an initial financial screen around deterministic calculations and traceable evidence. It is not an audit, CPA assurance engagement, or replacement for financial due diligence.
The Addback workflow
Bring spreadsheets, accounting exports, bank statements, and supporting documents into a target's data room.
Map financial records while retaining the original file and row.
Surface candidate adjustments, financial risks, and evidence gaps across ten checks.
Inspect the findings and choose CPA-led Advisory or deeper work in Platform.
