Independent science & technology company · Founded in Melbourne · Global in scope
J & Co turns curiosity into products, ventures and collaborations—building technology that helps people understand more, do more and stay connected to what matters.
Reality is more interesting than fantasy.Real work · Honest status
One venture direction and two physical prototypes, separated by what kind of work they are and what exists now.
AI governance & control
Magpie Net is investigating how organisations can retain clearer, inspectable control over which AI services may be used, what information may go where, who may spend what and how the organisation leaves.
RESEARCH QUESTIONS ACTIVE · NOT AN AVAILABLE PLATFORM SERVICE

Environmental measurement
A working two-node air-quality prototype: one for the desk and one designed for solar outdoor use, both feeding a local measurement and dashboard pipeline.
LOCAL DATA PIPELINE WORKING · ENCLOSURE AND RELIABILITY VALIDATION REMAIN

Light, colour & future room sensing
A touch-controlled ambient lamp exploring colour, light and—later—understandable room-air sensing. Two PCB-based lighting prototypes are operating on desks and in real use. Their ambient effect is already useful; brightness, thermal validation, sensing and logging remain in development.
TWO WORKING LIGHTING PROTOTYPES · SENSING NOT YET INTEGRATED
Ask about the build →Alongside our own work, we take on a small number of paid collaborations where privacy, measurement or a difficult technical system is central to the problem.
You do not need a finished brief. Tell us what you are trying to understand, change or build, what constraints matter and where you are stuck.
Clarify how tools, information, decisions and exit paths should work around a real organisational constraint.
Prototype and test environmental or scientific measurement systems, stating clearly what the evidence can and cannot show.
Make a complex software, hardware or data system tractable, then build the smallest useful next step.
Look closely and the world is already stranger, deeper and more full of possibility than it first appears. That curiosity is where our work begins.
A useful technology might be a physical object, software, a system or a better way for people to connect. What matters is whether it expands real human capability.
We want what we build to leave people with more choice, capability and room to grow—while remaining connected to themselves, their families and communities.
The best technology can feel like magic while giving people more understanding and control, not less.
