The premise
Not another
government
conference.
There is no shortage of conferences, trade shows, webinars and product demonstrations.
What is harder to find is a place to actually understand the technology.
TECH FOR GOVIES was created to make those conversations possible. Each IMMERSION takes one technology problem and brings a small group of public-sector practitioners together with the scientists, engineers and companies working at the edge of the field.
- Q01How does it work?
- Q02What is genuinely new?
- Q03What has been proven?
- Q04What are its limitations?
- Q05What should a technically sophisticated evaluator know before taking it seriously?
No exhibition hall.
No booths.
No sponsorship presentations.
No sales pitches.
Just serious technical exchange.
Immersion 01 · Topic
On-person screening:
what's next?
The December 9 Immersion will examine the next generation of walk-through technologies for detecting threats carried on the person.
Radar-Based Walk-Through Screening
RF / mmWave-adjacent sensing
Emerging radar approaches to detecting concealed threats in motion, at throughput.
Scope note
This Immersion is not focused on millimeter-wave body scanners or backscatter systems.
Objective
The objective is not to select a winner or conduct a procurement. It is to help sophisticated government professionals understand what is emerging, how the technologies work, what they can and cannot do, what evidence exists, and how close they are to meaningful operational deployment.
Protocol
The technical
exchange framework
Every selected company participates through the same six-stage framework. Not an agenda — a protocol. Marketing language has nowhere to hide inside it.
STEP 01
The Science
How does it actually work?
First principles. Physics, sensing modality, signal chain, processing. Explained by the people who built it.
STEP 02
The Capability
What can it detect — and under what conditions?
Detection envelope, materials, geometries, concealment, motion, environment.
STEP 03
The Evidence
What has actually been tested, independently validated or deployed?
Demonstrated performance separated from projection. Who ran the test, and under what protocol.
STEP 04
The Limitations
Where does it struggle? What are the tradeoffs?
Failure modes, boundary conditions, and the engineering compromises behind the design.
STEP 05
The Operational Reality
What does it take to actually run it?
Throughput. Nuisance alarms. Footprint. Integration. Calibration. Maintenance. Staffing.
STEP 06
The Questions
What does the room want to know?
Government participants interrogate the technology and its claims directly with the people who built it.
Same framework · Every technology · Every Immersion
For government
Come curious.
Leave better informed.
Attendance is limited and curated to keep the discussion technically substantive. The room is built for people who will be asked hard questions about this technology by someone else later.
CostGovernment participation is free.
LogisticsExact DC-area location and detailed logistics are provided directly to confirmed participants.
AdmissionSubmitting interest does not automatically guarantee admission.
Who is in the room
Government professionals involved in:
- 01Technology evaluation
- 02Testing
- 03R&D
- 04Requirements
- 05Acquisition
- 06Operations
- 07Deployment
- 08Security policy
Curated for relevance, not headcount.
For technology companies
More than access
to the room.
Selection is technical, not commercial. What you get is harder to buy than a meeting: an accurate read on how expert government evaluators think about your technology.
Engage with sophisticated government practitioners
Explain the technology directly to people involved in evaluation, testing, requirements, operations, deployment and acquisition.
Understand the government technical lens
Learn which performance claims, evidence, limitations, integration issues and operational considerations government professionals need to understand when assessing emerging technology.
Use a common technical framework
Every participating technology is explored through the same substantive framework rather than competing through marketing language.
Create a durable technical resource
Participating companies will have the opportunity to create a standardized TECH FOR GOVIES Technical Brief capturing the key information government professionals need. Subject to company approval and appropriate access controls, these materials may remain available after the Immersion to qualified government users.
Hear the questions
Direct exposure to the questions, concerns and operational realities that sophisticated government users bring to emerging technology.
This isn't a booth. It isn't sponsorship. And it isn't lead generation.
It's an opportunity to have a serious technical conversation with the people government relies upon to understand emerging technology.
Applications reviewed on a rolling basis · Participation is limited
Beyond December 9
Technical
Briefings
TECH FOR GOVIES is designed so that useful technical exchange does not necessarily disappear when the Immersion ends. Each participating technology can eventually have a secure, government-facing profile.
Technical Brief
Structured technical information using the TECH FOR GOVIES framework.
Technical Briefing (Audio)
A short, curated 8–12 minute audio conversation with the scientist, engineer, founder or technical lead behind the technology. Audio is the standard format — fast to produce, easy to approve, listenable anywhere.
Optional Demonstration Video
Companies may attach a short video clip showing the product in operation — hardware, interface or field demonstration — as supporting evidence.
Supporting Evidence
Approved testing, validation, technical papers and other supporting material.
Briefing prompts
- Explain the technology in plain English.
- What's actually novel?
- What can it detect?
- What evidence supports the claims?
- What's the biggest limitation?
- What would a government evaluator misunderstand from looking at your website?
- What still needs to be solved?

Rules of the room
The rules are simple.
No sales pitches.
Technical exchange, not sales theater.
Bring the people who know the technology.
Scientists, engineers, technical founders and product experts.
Talk about the limitations.
What a technology cannot do matters.
Back up the claims.
Separate demonstrated performance from projections.
Use the common framework.
Every technology is examined through the same core questions.
You control your technical materials.
Post-event materials are subject to agreed company approval, access and confidentiality rules.
No pay-to-play government access.
Participation does not constitute government endorsement, testing, certification, procurement preference or approval.
Respect the room.
No attendee lists for solicitation. No unauthorized photography or recording.
A small room.
One technology problem.
The people who actually understand it.
