Founder note
Investigation work is rarely limited by a lack of information. The harder problem is keeping sources, reasoning, uncertainty, and review connected as a case develops.

01
An investigation gets harder as sources, documents, identities, relationships, and dates build up. A team must still preserve why each detail matters.
The work spreads across tabs, files, tools, notes, and reports. Soon the investigator spends as much time reconstructing context and checking prior reasoning as finding the next supported lead.
02
SIERRA is a local-first workspace for active investigations. It connects evidence, entities, timelines, notes, and tool output while the investigator stays in control of the working material.
Phantom Agent handles the research groundwork. Give it the question, review the sources and findings, then decide where the investigation goes next. Neither product replaces professional judgment.
03
Phantom Helix is for investigators, analysts, OSINT researchers, fraud teams, and due-diligence practitioners. Their work often moves between people, organizations, assets, disputes, infrastructure, and public records.
The tools keep evidence traceable and uncertainty visible. They also preserve enough source context for another professional to review or continue the work.
Working standard
The point is not to automate a conclusion or decorate a graph. It is to preserve enough context to understand, challenge, revisit, and hand over the work.
01
Keep claims next to sources
A finding should remain connected to the material and source scope that support it.
02
Separate findings from leads
Supported findings, candidate pivots, blocked checks, and open questions should stay distinct.
03
Keep context attached
Entities, relationships, dates, notes, and tool output should remain understandable together.
04
Make review possible
Another investigator should be able to inspect the evidence, challenge the reasoning, and continue the work.
Why it matters
I have seen how much clear information and real community support can matter when people are under pressure.
I want useful investigative tooling to be available to professional teams that cannot justify extremely expensive software. SIERRA and Phantom Agent are two ways I am testing that goal.
Real workflow feedback
Feedback from real, recurring investigation work is more useful than a generic feature list. Explain where source collection, review, or report preparation still breaks.
Choose the next step
Use SIERRA when you need to work the live case locally. Use Phantom Agent when you want the public-source research gathered and organized before your team takes over.
