Use cases
The same record.Wherever knowledge is made.
Labs, R&D, product, and strategy teams work in different tools. Proofline is the system of record underneath — so the thinking behind the work compounds instead of disappearing.
The substrate
Capture. Connect. Compound.
C³
- 01CaptureReasoning as the work happens.
- 02ConnectEvidence into a living record.
- 03CompoundKnowledge the next project can use.
Who it's for
The same problem, wherever teams create knowledge.
Different environments. Same underlying issue — the work is recorded, the reasoning is not.
Researchers
When the experiment ends, the reasoning should not.
- Research & DiscoveryDiscovery that builds on itself.
- R&D InnovationLess repetition, more breakthrough.
- Strategy & IntelligenceStrategy that can explain itself.
Enterprise R&D
When the project ships, the thinking should remain.
- R&D InnovationLess repetition, more breakthrough.
- Product DevelopmentSmarter decisions, faster iteration.
- Engineering & ArchitectureBetter systems, fewer repeats.
- Investment ResearchStronger theses, better investments.
Where it applies
One substrate. Six forms of knowledge work.
Select a case. Capture, connect, and compound stay the same — the work around them changes.
A paper keeps the result. The question, the dead ends, and why this experiment came next usually do not.
- 01CaptureQuestions and results as they happen, including the ones that fail.
- 02ConnectEvidence to hypotheses so a finding is never an orphan claim.
- 03CompoundThe next investigation starts from what this lab already knows.
Discovery that builds on itself.
Experiments produce data. The decision that followed, and the failure that taught you something, live in chat and someone's head.
- 01CaptureRuns, observations, and failed paths as the work unfolds.
- 02ConnectThose traces to the hypotheses and decisions they changed.
- 03CompoundInstitutional memory so teams stop re-running last year’s work.
Less repetition, more breakthrough.
Signals arrive. The assumption that shaped the call is gone by the next quarter.
- 01CaptureAnalysis, meetings, and scenarios as they unfold.
- 02ConnectAssumptions to options and outcomes.
- 03CompoundSo the next decision can see why the last one was made.
Strategy that can explain itself.
Feedback, experiments, and roadmap calls scatter across tools. The decision survives. The evidence does not.
- 01CaptureResearch and metrics as they land, not after the review.
- 02ConnectInsights to the hypotheses and decisions they produced.
- 03CompoundProduct knowledge so iteration starts from evidence, not a new slide deck.
Smarter decisions, faster iteration.
Design docs and incidents exist. The trade-off that produced the current system does not.
- 01CaptureDecisions, PRs, and incidents while the context is still attached.
- 02ConnectArchitecture to the rationale and the outcome.
- 03CompoundEngineering memory so the same regression is not paid for twice.
Better systems, fewer repeats.
Notes, models, and IC discussion live in different places. The thesis is hard to reconstruct a year later.
- 01CaptureResearch, calls, and memos as the case is built.
- 02ConnectTheses to the evidence and the decision.
- 03CompoundFirm knowledge so judgment improves instead of resetting with each analyst.
Stronger theses, better investments.
Make organizational intelligence compound.
Proofline. The reasoning infrastructure for the age of AI.
