Which Pet Tech startups make the most revenue today?

Whisker is the clearest Pet Tech revenue leader today, while Rover, PETKIT, Halo Collar, Tractive and Fi make up a second group ranging from roughly $100 million to well above $200 million in disclosed revenue or ARR.

The ranking gets messy because those numbers do not all measure the same thing. Whisker gives us current annual revenue. Rover's last clean public number comes from before Blackstone took the company private. PETKIT has reported annual revenue. Halo has recent annual revenue plus a higher current-year target. Tractive and Fi disclose ARR, which is useful for measuring current subscription scale but cannot be treated as recognized annual revenue.

Even with those differences, the top tier is fairly clear. Whisker generates more than $300 million annually. Rover's last public annual revenue was around $235 million. PETKIT reported roughly RMB1.1 billion for 2024. Halo made nearly $100 million in 2025. Tractive crossed €100 million ARR in 2024, while Fi says it is now approaching $100 million ARR.

After that, the numbers fall quickly. Wag! reported $70.5 million for 2024. Provet's veterinary business ended 2025 at €26.8 million ARR. Woofz generates about $20 million annually. Many other important Pet Tech companies disclose clinics, users, products sold or pets served rather than revenue.

Company	Best public scale figure	Metric	How we read it
Whisker	>$300M	Annual revenue	Strongest current direct revenue disclosure
Rover	~$235M	Historical annual revenue	Large, but the figure predates private ownership
PETKIT	~RMB1.1B	2024 revenue	Large global smart-device business
Halo Collar	Nearly $100M	2025 revenue	Recent actual revenue; current trajectory is higher
Tractive	€100M+	ARR	Large subscription business; total revenue is higher because hardware is excluded
Fi	Approaching $100M	ARR	Very fresh recurring-revenue disclosure
Wag!	$70.5M	2024 revenue	Filed revenue, although the business has changed since
Provet	€26.8M	Veterinary ARR	Strong veterinary-software disclosure
FirstVet	Tens of millions	Group revenue scale	Established tele-vet business
Woofz	$20M	Annual revenue	Rare eight-figure consumer pet app

Is Whisker really the biggest Pet Tech startup?

Yes. Whisker currently has the strongest public case for being the largest private Pet Tech company by revenue.

Whisker says it generates more than $300 million annually. That number is especially useful because it describes company revenue directly rather than ARR, marketplace volume or cumulative product sales.

The company has also kept adding scale around the financial figure. Whisker said in its recent retail expansion announcement that more than two million robots have now been sold worldwide. Its business has expanded beyond Litter-Robot into connected products for food, water and pet-health insights.

The interesting part is how far a once-niche product category has gone. An automated litter box became the starting point for a company with hundreds of employees, U.S. manufacturing, several connected products and nine-figure revenue.

Among Pet Tech companies for which we found current and reasonably comparable financial evidence, Whisker sits at the top.

Could Rover actually be bigger than Whisker now?

Rover could be much bigger than its last reported figure suggests, but current public evidence is too thin to move Rover ahead of Whisker.

Before Blackstone took Rover private, the pet-care marketplace had reached roughly $235 million in annual revenue. The acquisition then removed the regular financial reporting that made Rover easy to track.

Rover's merger documents show why this creates a real blind spot. Management's long-term plan projected revenue of $278 million for 2024, $338 million for 2025 and $403 million for 2026. Those were forecasts prepared before the transaction, so we cannot treat them as achieved revenue.

They do tell us something useful: Rover expected the business to keep growing substantially after the buyout.

That leaves Rover in an unusual position. The company may currently operate much closer to Whisker's scale than the last disclosed revenue suggests. We simply do not have a recent actual figure strong enough to prove it.

How big is PETKIT today?

PETKIT has already become a roughly mid-$100-million Pet Tech company, putting the Chinese smart-device business among the largest companies we found.

China Daily reported that PETKIT generated around RMB1.1 billion in 2024 revenue. More than 90% came from smart litter boxes, feeders and water fountains.

That product mix makes PETKIT particularly useful for understanding the economics of Pet Tech. The company did not reach scale through one experimental gadget. It sells technology around three things pet owners deal with every day: feeding, drinking and litter.

PETKIT is also much more international than its Chinese roots might suggest. Nearly half of its sales came from exports, with products sold across more than 40 countries and regions. Its connected app had more than five million users, with some paying for additional digital services.

PETKIT therefore belongs much closer to Whisker, Halo and Tractive in a revenue discussion than to the long tail of smaller connected-pet-device startups.

Is Halo Collar now a $100 million Pet Tech company?

Yes. Halo Collar has effectively entered the $100 million revenue tier after generating nearly $100 million in 2025.

Halo's growth has been unusually fast. The U.S. Chamber of Commerce previously reported that revenue climbed from roughly $3 million in 2020 to $75 million in 2024. Founder Ken Ehrman later told Entrepreneur that Halo generated nearly $100 million in 2025.

The company says it is heading toward about $140 million this year. We treat that higher number as a target rather than achieved revenue, but it shows how quickly Halo's current scale is moving.

Halo has also expanded the installed base behind that growth. The company says its GPS-powered collars have now protected more than 500,000 dogs.

This puts Halo in a different category from most pet wearables. It has already built a large revenue business around GPS fencing, safety and subscriptions rather than merely demonstrating that pet owners like connected collars.

How big are Tractive and Fi now?

Tractive and Fi are both around the $100 million ARR level, making GPS pet wearables one of the few Pet Tech categories with multiple companies at nine-figure recurring scale.

Tractive passed €100 million ARR in 2024. CEO Michael Hurnaus told GlobalPETS that total revenue was actually higher because the ARR figure covers subscriptions and excludes hardware sales.

Fi is following the same broad path. Founder Jonathan Bensamoun recently said Fi is approaching $100 million ARR and is on track to reach that level this year. The company has also expanded to 38 countries.

The two businesses look similar from a distance, but the recent moves are different. Tractive has broadened its position through health monitoring and acquired Whistle. Fi is pushing satellite connectivity through its Starlink-enabled Ultra collar.

What used to look like a small GPS-tracker niche has produced two subscription businesses around the $100 million mark. That is already enough to make wearables one of the most commercially proven parts of Pet Tech.

Why do Pet Tech hardware companies make so much money?

Pet Tech hardware companies reach large revenue quickly when an expensive device solves a problem owners deal with every day.

Whisker sells a premium home appliance. Halo sells a safety and containment system. Tractive and Fi combine connected hardware with paid subscriptions. PETKIT can sell several devices into the same household.

The first transaction is much larger than an app subscription. A consumer can spend hundreds of dollars before any recurring service begins.

Distribution also helps. Smart-pet products can sell through direct websites, Amazon, specialist pet retailers and international distributors. Veterinary software usually has to win clinics one by one, while consumer apps compete for subscriptions in crowded app stores.

The clearest pattern in our ranking is straightforward: connected hardware dominates the top end. Five of the six companies in the leading cluster sell a physical device as a core part of the product.

Which Pet Tech software companies make the most money?

Rover remains the biggest software-led Pet Tech company for which we have meaningful historical revenue, while veterinary software and consumer subscriptions currently sit much lower.

Rover reached roughly $235 million before going private, although its marketplace model is different from traditional SaaS.

Among current veterinary-software disclosures, Provet stands out. Nordhealth reported €26.8 million of implemented veterinary ARR at the end of 2025, up 10.9% from a year earlier. The business had scaled Provet to 13,500 veterinarians by the end of the year.

Woofz shows a different route. The dog-training app generates about $20 million annually, with around 120,000 active subscribers and more than 20 million downloads when its founder discussed the business.

Digitail says more than 10,000 veterinarians use its platform and that it serves more than four million pets. MoeGo says more than 10,000 pet businesses use its software. Neither company publishes a sufficiently clear revenue figure for us to place it alongside Provet with the same confidence.

Pet Tech software business	Best public scale evidence	Model
Rover	~$235M historical revenue	Pet-care marketplace
Wag!	$70.5M 2024 revenue	Marketplace / wellness platform
Provet	€26.8M veterinary ARR	Veterinary practice software
Woofz	$20M annual revenue	Consumer training subscription
Digitail	10,000+ veterinarians, 4M+ pets	Veterinary practice software
MoeGo	10,000+ pet businesses	Pet-business software

Is veterinary software becoming a big Pet Tech business?

Yes. Veterinary software is still smaller than the leading consumer hardware companies, but it is becoming one of the clearest recurring-revenue businesses in Pet Tech.

Provet gives us the best financial view. Veterinary ARR rose from €24.2 million to €26.8 million during 2025. Nordhealth also reported particularly strong growth in the U.S., UK and Southern Europe.

The customer base is becoming more enterprise-heavy. Provet has been rolling out across large veterinary groups, including deployments involving hundreds of clinics.

The software is also getting deeper into the clinical workflow. Provet has added AI-generated medical documentation and other AI features, while newer companies such as HappyDoc and Scribenote are building directly around veterinary notes and workflow automation.

Once practice-management software sits at the center of scheduling, records, billing and clinical operations, replacing it becomes painful. That makes veterinary SaaS slower to sell than a consumer gadget, but potentially much stickier once installed.

How big is tele-vet Pet Tech today?

Tele-vet has grown into a real commercial Pet Tech category, although the available revenue figures remain far below the biggest hardware companies.

FirstVet is the most established example in our research. The company operates across several markets, and its service has completed around one million video calls. Current FirstVet materials say the company works with millions of pet owners worldwide.

Dutch says it reaches more than 900,000 pet parents. Vetster works with thousands of veterinarians. Airvet has built a sizeable telehealth footprint through consumer and employer channels.

The tricky part is that tele-vet companies often disclose reach more readily than revenue. A pet parent who has registered for a platform is different from a paying annual subscriber, and a completed consultation says little about how much revenue the company keeps.

So tele-vet is clearly past the experimental stage, but the public numbers still make the category look smaller financially than smart hardware and marketplaces.

Can pet-training apps really make serious money?

Yes. Woofz shows that a pet-training app can become an eight-figure business without needing the scale of a hardware company.

Founder Natalia Shahmetova told Business Insider that Woofz had grown to $20 million in annual revenue, with roughly 120,000 active subscribers and more than 20 million downloads.

That conversion is the interesting part. Pet apps regularly publish millions of downloads, but very few disclose comparable revenue.

Dogo, Zigzag and other training platforms have accumulated large audiences. Those user totals are useful for measuring reach, yet they do not tell us how many people pay, how long subscriptions last or how much the company keeps after app-store fees and acquisition costs.

Woofz gives us a cleaner answer. A consumer pet app can become a sizeable company, but the scale currently visible in public disclosures remains well below the largest connected-hardware businesses.

Why are Pet Tech apps still smaller than smart pet devices?

Pet Tech apps can reach millions of users, but the revenue gap with premium hardware remains huge because each paying customer is worth much less upfront.

A Litter-Robot, GPS fence or connected pet system can bring in hundreds of dollars at purchase. An app may need to keep the same customer subscribed for years to collect a similar amount.

Apps do have big advantages. They can launch globally with little physical infrastructure, margins can be high, and new features can be distributed instantly.

Customer acquisition is the hard part. Consumer subscription apps compete with entertainment, fitness, education and thousands of other mobile products for the same attention and advertising inventory.

The current ranking reflects that difference. Woofz has built an impressive $20 million business, while the leading hardware companies operate at several times that scale.

Is Pet Tech turning into pet health tech?

Yes. Connected Pet Tech is increasingly built around health data rather than convenience alone.

Tractive now tracks health indicators alongside location and activity. Fi is pushing further into continuous monitoring through its collars. PETKIT uses connected litter boxes, feeders and fountains to identify changes in eating, drinking and bathroom behavior.

Whisker's newer products are moving in the same direction. The company has added technologies such as individual-cat identification and deeper behavioral tracking around litter-box use.

Embark approaches the market from diagnostics rather than hardware. The company passed two million dogs tested through its DNA platform.

Veterinary software adds another layer by bringing AI into clinical records, notes and practice management.

These businesses are starting from different products, but they are converging on the same valuable asset: a continuous stream of information about an animal's behavior or health.

Which Pet Tech revenue numbers should we trust the most?

Rover, Wag!, Nordhealth and other companies with filed financial statements give us the cleanest evidence, while direct company disclosures from Whisker, Halo, Tractive and Fi are also strong enough to anchor the ranking.

Source quality changes how we read a number.

Wag!'s $70.5 million figure comes from an SEC filing. Nordhealth publishes audited accounts and detailed investor reports. Rover's historical numbers come from its public-company filings and transaction documents.

Whisker's revenue is disclosed directly by the company. Halo's latest actual revenue comes from a founder interview. Tractive's ARR was stated by management and subsequently reported across industry sources. Fi's ARR trajectory comes directly from its founder in recent interviews.

Further down the market, comparability deteriorates. Some companies only have third-party web-sales estimates, app downloads or customer counts.

We therefore give a clean $25 million filed or company-disclosed number more weight than a larger-looking estimate built from incomplete external data.

Which Pet Tech companies are probably bigger than their published numbers?

Rover, Tractive, Provet and several private veterinary-software companies probably have more current commercial scale than their headline figures show.

Rover is the obvious example because its last public revenue figure predates the Blackstone acquisition. Its internal forecasts anticipated continued growth, although we cannot substitute those projections for actual results.

Tractive's €100 million ARR milestone was reached back in 2024. Management said at the time that total revenue was already higher because hardware sales sit outside ARR.

Provet has also moved beyond the year-end figure used in the ranking. Nordhealth's more recent reporting shows the veterinary business continuing to expand, alongside larger enterprise deployments and additional AI products.

MoeGo and Digitail present a different problem. Their published customer footprints are large enough to suggest meaningful SaaS businesses, yet exact revenue remains private.

The ranking therefore understates some fast-growing private companies by design. We prefer an older defensible number to a current figure we would have to invent.

Which big Pet Tech companies still do not disclose revenue?

MoeGo, Digitail, CATLINK, Embark and several other sizeable Pet Tech companies have enough commercial adoption to matter even though public revenue evidence remains limited.

MoeGo says more than 10,000 businesses use its pet-business software, covering more than 11 million pets. Digitail reports more than 10,000 veterinarians and more than four million pets on its platform.

CATLINK says more than one million products have been sold worldwide and that the company has reached one million users. Embark has tested more than two million dogs.

Those figures show real scale. They still cannot be dropped into a revenue ranking as dollar amounts.

A million users could sit behind a very large business or a heavily freemium one. Two million products sold could have generated substantial cumulative sales while telling us little about this year's revenue.

Keeping those companies visible without fabricating revenue gives a more accurate picture of Pet Tech than simply excluding them.

Is Pet Tech revenue concentrated in just a few companies?

Yes. Publicly disclosed Pet Tech revenue is heavily concentrated in a small group, with a clear drop after the leading companies.

The top tier contains several businesses around or above the $100 million scale. Once we move below Wag!, most clean financial disclosures fall into the tens of millions.

That drop looks too large to dismiss as ranking noise. The Pet Tech market has a relatively small number of businesses that have already broken through to major commercial scale and a much larger group whose public evidence still points to smaller revenue or only operational adoption.

The pattern also explains why lists based on fundraising can feel misleading. A heavily funded company can appear prominent without showing strong revenue, while a less fashionable or bootstrapped company may quietly build a much larger business.

Commercial tier	Examples	What we see
$300M+ current revenue	Whisker	Extremely rare private-company scale
~$200M+ historical revenue	Rover	Marketplace model reached major scale before going private
Mid-$100M range	PETKIT	Global smart-home pet hardware
Around $100M	Halo, Tractive, Fi	Connected safety and wearable cluster
~$50M–$100M	Wag! historically	Few clean current disclosures
~$20M–$30M	Provet, Woofz and peers	Much denser group
Revenue undisclosed	MoeGo, Digitail, CATLINK, Embark and others	Operational metrics become more common

Can Halo, PETKIT, Tractive or Fi catch Whisker?

Halo, PETKIT, Tractive and Fi are now large enough to make the gap interesting, but none has publicly demonstrated current revenue above Whisker.

Halo is moving fastest on recognized revenue. The company went from a few million dollars earlier in the decade to nearly $100 million last year and is aiming substantially higher now.

PETKIT already has a broad international device portfolio and a large export business, giving it more ways to grow inside the same household.

Tractive and Fi have subscription economics on their side. Their recurring revenue can compound as the installed base grows, and both companies are adding more health features around the core GPS product.

Rover remains the wild card because current results are private.

For now, Whisker still has the clearest lead. The more interesting question over the next few reporting cycles is whether one of these challengers can turn roughly $100 million scale into several hundred million.

What Pet Tech business models scale the best?

Connected hardware currently produces the largest private Pet Tech revenue figures, while marketplaces and veterinary SaaS offer two very different ways to build large recurring businesses.

Whisker, PETKIT and Halo show how far a high-value physical product can scale. Tractive and Fi make the model more attractive by attaching subscriptions to the device.

Rover shows the marketplace route. The company takes a fee when pet owners book care, so growth depends on repeated transaction volume rather than manufacturing products.

Veterinary SaaS produces smaller headline numbers today, but the revenue is highly recurring. Provet sits inside the clinic workflow, while MoeGo and Digitail are building similar software depth in their respective parts of pet care.

Consumer apps have the lowest infrastructure requirements, though their current revenue ceiling looks lower. Woofz is a strong business precisely because reaching $20 million from a pet-training subscription is already unusual.

Funding does not map neatly onto any of this. Whisker reached huge scale without following the classic mega-round startup playbook, and Woofz built its current business without traditional VC funding. Revenue tells us much more than capital raised about which Pet Tech models customers are actually paying for.

How much of Pet Tech revenue is recurring now?

Recurring revenue is becoming a central part of Pet Tech, especially in wearables and software, even though the biggest company in the ranking is still hardware-led.

Tractive and Fi make subscriptions fundamental to the product. Provet sells SaaS to veterinary practices. Woofz earns recurring app subscriptions. Rover benefits from customers repeatedly booking pet-care services.

Halo mixes the initial device sale with ongoing service revenue. PETKIT and Whisker have more transactional hardware-heavy models, but both are building connected ecosystems that create more opportunities after the first purchase.

This changes how we should compare companies at similar revenue levels. A $100 million recurring subscription base can behave very differently from $100 million of one-time hardware sales.

For a ranking by revenue scale, we still keep the metrics separate. For understanding the businesses behind those numbers, the shift toward subscriptions is one of the biggest things happening in Pet Tech.

Where is Pet Tech going next?

Pet Tech is moving toward products that combine a physical device or professional workflow with recurring software, AI and health data.

Whisker is adding smarter identification and behavioral insights to connected cat-care products. PETKIT is pushing its devices toward continuous health monitoring. Halo, Tractive and Fi are making collars more useful beyond simple location tracking.

Veterinary software is changing at the same time. Provet now embeds AI directly into practice-management workflows, while newer companies focus on automatic clinical notes and other repetitive veterinary tasks.

The common thread is easy to see across those companies. The product gets installed once, then becomes more useful as it collects information and stays involved in daily pet care.

That creates a better business than selling an isolated gadget and hoping the customer comes back several years later.

So, what are the top Pet Tech startups by revenue today?

Whisker is the clearest Pet Tech revenue leader from the evidence available today, with Rover, PETKIT, Halo, Tractive and Fi forming the main group behind it.

Rover deserves the biggest asterisk because its current revenue disappeared from public view after the Blackstone acquisition. PETKIT has already built a major international smart-device business. Halo has moved into nine-figure territory unusually quickly. Tractive and Fi show that pet wearables can support subscription businesses around the $100 million ARR level.

Below that group, the market changes fast. Wag!'s last annual revenue sits below the leaders, and the strongest veterinary software, tele-vet and consumer-app companies mostly operate in the tens of millions or disclose operational scale rather than revenue.

The ranking also tells us something bigger about Pet Tech. The companies making the most money are solving ordinary, expensive and repeated pet-owner problems: litter, safety, tracking, feeding and care. Increasingly, they keep earning after the first transaction through subscriptions, software or connected services.

For now, Whisker has the cleanest claim to the top spot. Rover's private financials are the biggest missing piece, while Halo, PETKIT, Tractive and Fi are the companies making the next tier much more competitive.
