Peter Thiel Is Betting Big On Solar-Powered Cow Collars (inc.com) 87

Halter, a New Zealand agtech startup now valued at $2 billion, has raised $220 million to expand its AI-powered cattle management system. "Halter is now valued at $2 billion following the Series E, which was led by Peter Thiel's Founders Fund with participation from Blackbird, DCVC, Bond, Bessemer, and several others," reports Inc. From the report: Halter plans to use the funding to expand its existing footprint in the U.S., Australia, and New Zealand, as well as to grow into new markets such as Ireland, the U.K., and parts of North and South America. The round is one of the biggest to-date in the industry, and comes amid growing adoption of the technology among U.S. ranchers. According to Halter, U.S. ranchers have erected some 60,000 miles of virtual fencing since the company's launch in 2024.

Halter's technology works through a system of solar-powered collars and in-pasture towers that collect data -- some 6,000 data points per collar per minute -- from grazing cattle and feed it into a cloud-based platform and app for farmers. The collars are ergonomically designed to be comfortable for the cattle wearing them, and leverage AI to play audio cues or vibrate when it is time to move to a different grazing location or if they step outside of a predetermined zone. The collars can also deliver an electric pulse if an animal does not respond.

Halter's app also creates a digital twin of a ranch, which essentially means a digital replica that leverages real-time data to accurately reflect conditions. Farmers can consult the app to check on their herd, or fence, and move cattle with just a few clicks. Halter also has a proprietary algorithm that it calls a "Cowgorithm" trained on seven billion hours of animal behavior. Altogether, this technology is meant to make ranchers' lives easier when herding cattle, help them save money on building physical fencing, and provide insights about pasture management to improve soil health and pasture productivity. Halter says some 2,000 farmers and ranchers currently use its tech worldwide.

      The real question is it cheaper and easier to slap a collar on something than put up fences, train dogs, and hunt down strays. Manual labor is expensive and ranchers aren't exactly the type of folks to spend on new fangled tech that doesn't work. There's plenty of other ag tech that's been adopted over the years from milking machines to GPS-enabled tractors getting data on fertilizer placement. And the farmer's that haven't been pushed out of business have enough sense to do the calculations on return on investment on how tech investments will affect their bottom line.

      • Farmers have been using GPS collars to manage cattle grazing in a way that supports the restoration of fragile environments. Essentially mob grazing but without the need to put physical fences in areas here the terrain would make that prohibitively expensive. It's not the cheapest thing in the world but it does work well.

      • I'd say the other real question with adopting this solution is what happens to the AI-driven cloud-dependent Enterprise farming operation when the internet or AI service goes down. Hard. And they're flying blind.

        Once the farmer has "maximized efficiency" with a click-and-deploy wrangler team activated via text message, I'm guessing they'll do what everyone else does. Fire everyone else deemed "extra". Making downtime very expensive.

        Border collies generally work with sheep, cows not as much simply because cows don't really give a damn.

        But sheep you have to be careful with - an entire flock in the UK had to be euthanized because they figured how to escape their fencing, and if that knowledge spread, it would basically render all farms using that fencing to keep sheep worthless. They apparently are very good at teaching fellow sheep things like that, and it was only a matter of time before the one or two that figured out how to escape taught the rest of the flock, and that flock would then teach neighboring flocks on neighboring farms and so on. It was cheaper to euthanize the flock than to have the entire country's farms re-fenced.

      Nothing to do with herding them, it's to do with cattle management when you've got them spread over a large area. You can record where they are, whether they're getting enough food/water, whether they're sick or injured, etc. It's a huge improvement over either having no idea until you run across the carcass several months later or having farm hands spend several days each month going around guesstimating whether there are problems.
      • by caseih ( 160668 )

        Great points. I forgot about those other aspects. E-sheperd sends a warning to the phone if an animal doesn't move for a while.

        That said, herding definitely is a part of it. These systems can actually move cattle around a pasture. The cattle learn pretty quickly what the collar is trying to get them to do.

        • The herding portion is actually relatively new, originally it was purely a cattle-management solution and they were running their trials in places where where you had cattle spread out over an impractical-to-keep-an-eye-on area. They spent a lot of time figuring out how to make the things both cow-proof and outdoors-environment-proof, making something IP54 isn't too hard when it's bolted onto a wall and there are no size constraints but doing it when it's strapped to a cow and as small as possible was a hu

      I can tell you are not a rancher.

      There's a Canadian company doing something similar called e-shepherd. It's more than a virtual fence. It's part of an integrated grazing plan. Currently there's a certain number of acres required for a certain number of cattle. The cattle don't graze randomly, so you end up getting areas that are overgrazed and the grass damaged. With e-shepherd or a system like this one, the cattle can be slowly moved around the pasture. This basically allows you to keep the same amount of cattle in a much smaller area, as you can move them more frequently without a lot of gates and fences. It doesn't take long for the cattle to figure it out, and it's quite remarkable how the collars can train them to move when you (or the AI!) want them too. It really does work.

    I’ve got plenty of gripes about Thiel, and the 2-billion dollar valuation is the standard I-estimate-my-company-as-being-worth-all-teh-mmmoonnaayyy.

    But this idea seems solid and worth pursuing. It’s a real market, for real goods, that probably could benefit from some tech. There’s use case is extremely low on buzzwords. No AI. No blockchain. No crypto. Just a solid case for a hardware/software system that could probably improve actual physical productivity in an easily measurable way. The argument for using cloud infrastructure is pretty compelling.

    The kicker is if costs can be low enough to justify, that’s a LOT of fairly advanced hardware to purchase, install, and deal with wear and tear in an aggressive outdoor physical environment, in order to get my cows to grow 20 percent better. Is it worth it? I have no clue, but that’s gonna be the main question to answer. Agriculture is a very-low-bullsh&t industry.

    To the people who are griping about Thiel planning to use this on humans. Your worries are 5 years too late.

      But this idea seems solid and worth pursuing. It’s a real market, for real goods, that probably could benefit from some tech.

      Agreed. I live in the mountain west, and our forest and mountain landscapes are just covered with fencing, even though most of it is public land, because it's BLM "multi-use" land -- a lot of cattle graze on it. Fences are expensive to build and expensive to maintain. If you think a fence is something you build once and then ignore, you've never dealt with cattle.

      Cowboys (and sheep herders) have a term "ride fence" as in "Bob, you're gonna ride fence today", and it's a regular and tedious task that means "get on your horse (or ATV) and ride past miles and miles of fenceline, looking for places where the fence is broken or going to break, and fixing them". It's necessary and expensive drudgery and having all of those fencelines is bad for other uses, and bad for wildlife. I've put down a few deer that jumped a barbed wire fence and didn't quite clear it, slicing their guts open and leaving them in agony as they slowly die.

      In addition, there's an obvious tension between the cost of building and maintaining fences and the cost of rounding up cattle when it's time to move them. Obviously if you slice the land up into lots of small fenced areas, the cattle will be easy to find -- but they're also going to graze it out fast, so you're going to have to move them more often. If you use very large enclosures (common on BLM land), then your cows may have hundreds of square miles to roam and feed... but when it's time to move them you have to find them. Luckily they're herd animals so when you find a few you've found them all, but still. And occasionally, singles get separated from the herd and you just lose them, which isn't great since a cow is worth about $2k.

      So... if we can replace those miles of expensive and constantly-breaking fences with virtual fences, that's good news for everyone. Wildlife and outdoorsmen can roam unimpeded, cattle can be far more tightly controlled, strays quickly identified, located and reunited with the herd -- via remote control!. This is an innovative idea that is worth quite a lot.

      Agreed also. Cattle rancher here in Central Texas with certified organic ranch and cattle. Another advantage is implementing rotational grazing, in which the herd(s) are moved every day or so to fresh grass. Doing so with fencing requires either a lot of fixed fencing or movable electric fencing. The first is expensive in materials and upkeep, the second in labor (moving the fencing every time the herd is moved). Virtual fencing is an excellent solution.
      Another advantage to rotational grazing for organic ranching is that the life cycle of worms requires reingestion of fecal material into a new host within 30 days. By making sure the herd never returns to a given area within that interval removes the need for de-worming agents (which we can't use-we accept decreased growth or treat and then sell severely infected animals). This is good for non-organic ranchers also because routine use of de-worming agents leads to parasite resistance.
      Another advantage for all ranchers is tracking cattle. Cows about to deliver will often go off from the herd into isolated parts of the pasture. If they run into trouble and need help with delivery, the rancher first has to find them. With this technology, the rancher can set up a separate virtual paddock and give the cow(s) separation from the herd while retaining the ability to keep an eye on her/them.
      For me, the issues are cost and proprietary software. The cost is naturally high, about $350-500 per animal for the equipment and an annual monitoring fee. That's pretty steep for me since my profit margin is low (organic certification alone is expensive). And, the devices communicate with a proprietary service. If the company goes out of business or decides to stop the service, the hardware becomes useless. I don't think I'll be buying the equipment until I find a work-around for that problem.

      Not stupid. Cattle are quite clever when it comes to finding food to feed the bacteria in their fermentation vats (the rumen, their first stomach).
      The issue is that each pasture has grasses of better and lesser quality. The cattle will eat the better grass before eating the poorer grass. The rancher wants the cattle to eat just the better grasses about 50% of the length of the leaves. If the cattle are moved elsewhere at that point, the better grasses will grow more vigorously so there will be more of them
