Why we’re building our own bat sensor

M4P S1 is a knob-mounted bat swing sensor. We are designing and engineering it in-⁠house, under the CEJ Ventures name.

The problem

Movement 4 Power measures before it coaches. Every athlete starts with an assessment, gets a written evaluation and a 4-⁠week plan, and is then re-⁠tested against that baseline. The swing is part of that record. M4P measures it with Blast Motion and Diamond Kinetics.

Measured swings are how M4P coaches hitters. Access to that kind of data should not depend on what a family can spend. M4P S1 exists to put reliable swing data within reach of families, at a price they can afford.

Why build it

The sensors M4P uses today do their job. Building our own is not a verdict on them. It is how the house works. When a problem sits inside one of our own companies, we build the answer ourselves, put it to work there, and keep what we learn.

Building it ourselves also means we decide what it measures, how it is made and what it costs. For families, the last of those matters most.

Where it stands

The working prototype is complete. It is a prototype, not a product, and the final hardware may differ from it. We are not publishing specifications, measurements or a price until they are settled. There is no release date.

Who uses it first

Our method says what comes next. A product goes in front of real customers inside our own companies before it goes anywhere else. For M4P S1, those customers are Movement 4 Power’s players and coaches. They already work from measured swings, so they will tell us plainly where it falls short.

What happens next

Next, the prototype has to hold up in training, swing after swing. If a release date is set, the early access list hears it first.

If M4P S1 starts to earn revenue, it leaves CEJ Ventures and becomes a company of its own inside CEJ Holdings. If it does not earn its place, we shut it down.
