It’s way smarter than it sounds. Cowlar makes a special collar for cows that tracks their temperature, activity and other data, and makes it available to farmers. It can recognize a cow with an infected hoof from the change in its gait, or identify that a cow is pregnant and will eventually produce milk. Cowlar costs $69 per cow with a $3 per month subscription, and provides a solar-powered “cow router” that collects data from the collars. It already has 600 cows on the platform, with 7,200 on the waitlist, and has alerted farmers about 103 sick cows. It already has the opportunity to build an $11 billion business on milk cows, and could enter the 3X bigger beef cow market next. While the idea might seem ridiculous, cows are a huge part of the economy, and more data on them leads to more revenue from them.
