Green Line Analytics, LLC · Massachusetts
Research-driven solutions that protect consumer privacy, safety, and autonomy.
Green Line Analytics, LLC monitors consumer technology for the vulnerabilities and overreach that go unnoticed by the people affected — then builds what is missing. Patented detection technology, security research, and quantitative analysis, with every conclusion held to evidence.
Recent impact · March 2025
A flaw in millions of living rooms.
Green Line research identified a security vulnerability in Amazon Fire TV's web-based virtual remote and keyboard. The flaw could have allowed an attacker to install malware on affected devices.
Following disclosure, Amazon suspended the feature entirely. It was later restored with improved security. The finding was covered by technology and consumer press across the United States, the United Kingdom, and the Netherlands.
This is the work in its clearest form: a widely deployed consumer device, a flaw its owners had no way to see, and a fix that reached them because someone went looking.

Holdings
Three ventures, one thesis.
Green Line Analytics, LLC is a holding company. Each venture operates independently, but all three address the same problem from a different side: people cannot protect themselves from risks they cannot see.
Vulnerability disclosure
We examine widely deployed consumer devices for security weaknesses and report what we find to the manufacturer, so it can be fixed before it is exploited.
The work is unglamorous and mostly invisible. It matters because the people using these devices have no practical way to evaluate them, and no recourse when something is wrong.
Passive radio detection and signal correlation
Nearly every powered device now broadcasts something — a beacon, a probe, a periodic signal. Those transmissions are public, unencrypted, and continuous. B-Hound is a passive receiver and correlation engine that reads them and answers a deceptively simple question: which of these signals has been travelling with this person, or lingering in this place, for longer than it should?
The method is general because the question is. Distinguishing a device that follows from one that is merely present is the same computation whether the subject is a tracker in a bag, a sensor on a job site, or equipment that has left a building. What changes is which answer matters.
Applications under evaluation:
- Personal safety — detecting hidden trackers and covert recording devices
- Family and caregiving — consented awareness for households and memory care
- Asset and equipment tracking — locating tools, inventory, and hardware without a fixed installation
- Worksite safety — proximity awareness and evacuation accountability
- Counter-surveillance auditing — surveying a space for devices that should not be present
- Aggregate measurement — occupancy, flow, and dwell analysis with no individual record retained
The same signals that make surveillance possible make detection possible. The difference is what happens next: surveillance stores what it sees; detection does not. That distinction is architectural, not a matter of policy.

Statistical consulting, dissertation and research support, curriculum design, and corporate analytics training for institutions, researchers, and teams.
This is the methodological backbone of the group. Detection is a classification problem before it is a hardware problem, and the standards that govern peer-reviewed research — study design, error control, reproducibility — are the same ones that decide whether a safety product can be trusted.

Findings are only useful if they can be trusted.
Security work invites overstatement. A finding that cannot be reproduced, or a product whose safeguards exist only in its marketing, does more harm than doing nothing. These are the constraints we hold ourselves to.
The manufacturer hears first
When we identify a vulnerability, we report it to the company that can fix it and give them the time to do so. Public attention comes after a remedy exists, not before. The purpose is a fix, not a headline — and reports about our own work reach us at security@greenlineanalytics.com.
Claims carry their limits
Every finding is documented, reproducible, and stated alongside what it does not establish. Where a method has a known failure mode, we publish it. Overstating what a safety tool can do is its own kind of harm.
Safeguards built in, not promised
Our detection technology cannot be repurposed into surveillance, because it never gathers what surveillance would need. Data that is never collected cannot be leaked, subpoenaed, or sold. That is a design decision, not a policy.
Leadership
Who we are.
A small group combining quantitative research, criminal law, enterprise sales, and financial operations — a mix suited to work that has to be technically sound, legally careful, and viable as a business.
Two decades in statistical analysis, consulting, and instruction, and a Senior Lecturer at the Isenberg School of Management, UMass Amherst, with peer-reviewed research in emergency medicine and higher education outcomes. Leads the group's quantitative research and directs its analytics practice.
More than thirty years as an assistant district attorney in West Hartford, Connecticut. Advises on the legal boundaries that shape what the group builds.
Two decades in telecommunications and cloud contact center software, and Vice President of Sales Strategy at Five9, where he is a five-time President's Club recipient. Leads revenue strategy and partnerships for the group.
Financial operations for small and mid-sized businesses — bookkeeping, custom reporting, inventory and fixed-asset tracking, and the analysis owners rely on to make decisions. Advises on the commercial and operational side of the group's ventures.
