Thesis mapping
Connect value creation logic, risks, underwriting questions, and assumptions in one deal map.
Where diligence breaks
Deal teams can find the file,
but lose the reasoning
Diligence moves across VDR folders, email threads, partner comments, memo versions, and IC updates. The source material remains searchable. The logic behind the deal often becomes tribal memory.
Reasoning thins at every handoff
First look, diligence, partner review, IC prep. Each transition loses context about why the case changed and who accepted the change.
Memos lag the live deal
Assumptions move faster than the document. Teams need a durable view of what changed, what conflicts, and what still needs judgment.
Evidence separates from conclusions
Source materials pile up, but the link between a conclusion, the evidence behind it, and the reviewer who approved it becomes fragile.
Changes are hard to explain
When the thesis evolves, teams spend valuable time reconstructing the delta instead of reviewing whether the new reasoning deserves conviction.
Not search. Not memo automation. A reviewed reasoning record for the live deal.
Parallax keeps thesis, evidence, open issues, reviewer decisions, and memo deltas in one source-backed workflow.

From live diligence to IC-ready judgment
Source-linked evidence
Attach conclusions to calls, reports, VDR documents, model excerpts, and reviewer notes.
Issues, gaps, contradictions
Track changed assumptions and unresolved diligence items without separating them from source context.
Human review
Review AI-proposed updates before they become part of the deal record.
Memo deltas
Show what changed since the last memo, why it changed, and what still needs judgment.
Built for high-stakes deal judgment
Parallax is designed for diligence where evidence, review, and accountability matter as much as speed.
AI proposes, humans decide
Parallax helps structure updates, but investment judgment stays with the team.
Evidence stays attached
Every material conclusion links back to the source materials and assumptions behind it.
Reasoning survives handoffs
The logic of the deal remains legible across deal teams, reviewers, memos, and time.
Reviewed state, not raw output
Proposed changes become part of the record only after review, context, and approval.
Built by people who lived the problem
We have seen how deal logic scatters across models, calls, memos, and people. Parallax is built for teams that need the reasoning to stay as durable as the decision record.
