Halter
Halter builds solar GPS collars that herd and fence cattle by app, no wires needed.

The call
Halter leads a young virtual fencing market with real hardware and regulatory footholds, while Merck and Gallagher build competing collars nearby.
Halter sells electronic collars that train cattle to stay in invisible fenced areas using location data from satellites and vibration or sound signals. The company has built something hard to replace quickly because it combines physical hardware (the collar itself), years of training data on how animals actually behave, and satellite technology all working together, so a software-only competitor or an AI system cannot do the job remotely. However, two large farming companies, Merck (through its Vence product) and Gallagher (through eShepherd), are already selling competing collars and have deep pockets to improve them, so Halter's advantage is real but requires constant defense. The thing that could change everything is if either Merck or Gallagher decides to cut prices sharply or bundle their collar with other farm products farmers already buy, which would force Halter to compete on cost rather than just technology.
Why
01
AI pressure: None apparent. Halter uses its own AI to train animal behavior; no outside AI product currently threatens the collar business itself. Could AI do the core job? Unlikely.
02
Bigger players: Merck Animal Health (Vence) and Gallagher Group (eShepherd). Both sell live virtual fencing collars backed by large animal-health and farm-equipment balance sheets. Could a giant copy it? Probably.
03
What protects it. Over 1,000,000 collars already trained on animals across 2,000+ farms, plus satellite deals and state-level regulatory approvals.
What would change this call
Vence announces satellite-connected collars matching Halter's Starlink launch. Would show Merck closing the technology gap and directly contesting Halter's edge.
Gallagher reports eShepherd unit sales or new-market expansion in 2026-2027. Would show Gallagher scaling enough to pull ranchers away from Halter.
UK, Ireland, or South America regulators restrict electrical-stimulus virtual fencing. Would show regulatory risk blocking Halter's planned geographic expansion.

Key numbers
- $220M Series E at roughly $2B valuation
- Over 1,000,000 collars sold worldwide
- 250,000+ US collars across 25+ states
Named risks
- Merck (Vence) or Gallagher (eShepherd) could price-compete aggressively using far larger balance sheets.
- UK, Ireland or South American regulators could restrict electrical-stimulus virtual fencing before planned entry.
- Champion Station extensive-grazing trial in Australia could fail to prove collar scalability on vast rangeland.
- Revenue figures across aggregators conflict wildly ($27.8M to $89.4M), no audited financials exist.
Rivals, as read in July 2026
| Rival | Direction | Evidence |
|---|---|---|
| Vence (Merck Animal Health) | contesting | Merck-owned Vence ships competing US virtual fencing collars, no reported share loss for Halter as of 2026 |
| eShepherd (Gallagher Group) | contesting | CSIRO-derived eShepherd competes in Australia where Halter holds 2025-2026 state approvals |
| Nofence | contesting | Norway's Nofence covers sheep and goats via cellular mesh, a niche Halter's collar does not target |
Questions people ask
- Is Halter profitable in 2026?
- Halter has not disclosed profitability; it is private and closed a $220M Series E in March 2026 at a $2B valuation, with funds earmarked for global expansion rather than reported profit, per the company's own March 24, 2026 announcement.
- Could AI replace Halter's product?
- No. Halter's core offering is a physical solar-powered collar on a live animal requiring multi-year behavioral training and satellite or cellular links; AI is built into the collar's guidance system, not a substitute for the hardware, as of 2026.
- Who owns Halter?
- Halter is privately held, founded in 2016 by Craig Piggott. Its March 2026 Series E was led by Founders Fund with Blackbird, DCVC, Bond, Bessemer and others, valuing the company at $2B, per Halter's own release.
- Who is Halter's biggest competitor?
- Halter's main rivals are Vence, owned by Merck Animal Health, and eShepherd, owned by Gallagher Group and derived from CSIRO research; both already ship competing virtual fencing collars with large corporate balance sheets behind them.
- Has Halter expanded to the United States?
- Yes. Halter launched in the US in August 2024 and by June 30, 2026 reported over 250,000 collars sold across more than 1,000 ranches in 25-plus US states, per Halter's own product announcement.
- What is Halter's current valuation?
- Halter was valued at approximately $2B USD following its $220M Series E round, announced March 24, 2026 and led by Founders Fund, according to Halter's own press release.
