How Startups and New Entrants Are Reshaping the Animal Health Landscape

What 500+ Animal Health Startups Mean for the Industry

Insights from Joseph Harvey, Head of Animal Health at S&P Global (Agribusiness Intelligence), who has covered animal health M&A, startup ecosystems, and industry rankings since 2012. Shared during Prelude’s Animal Health Insights webinar series.

A decade ago, you could count the number of animal health startups on one hand. Today there are more than 500. The funding is real, the categories are diversifying, and the Big 4 are paying attention. But the industry is still in the early stages of figuring out what startup success actually looks like in animal health.

Joseph Harvey has been watching this unfold from the analyst’s seat for 14 years. A journalist by training who previously covered human med tech and diagnostics, he moved to animal health in 2012 and never left. His day-to-day involves interviewing CEOs at the largest animal health companies and tracking two-person startups with unproven technology and ambitious plans. He produces S&P Global’s “Disruptors and Innovators” startup profiles and the flagship “Growth Drivers” annual report.

During a recent Animal Health Insights webinar, Harvey shared what he’s seeing across the startup landscape, where the real traction is, and what the ecosystem still needs to mature.

1. The Startup Landscape Went from Nearly Zero to 500+ Companies in a Decade

When Harvey started covering animal health in 2012, there were perhaps two or three startups focused solely on the industry. Today, he estimates between 500 and 600 animal health startups globally, spanning companion animal therapeutics, livestock monitoring, diagnostics, feed additives, and pet health technology.

The catalyst was visibility. The Zoetis IPO, the Elanco public listing, and a series of billion-dollar deals (Elanco acquiring Bayer’s animal health division, IDEXX’s sustained growth story) put animal health on the map for entrepreneurs and investors who had never considered the space. As Harvey put it, the big businesses in animal health grew so much over the last decade that they were able to highlight how attractive the industry is to outsiders.

The growth is also globalizing. The US and Europe still produce the majority of startups, but Harvey is seeing increasing activity from Japan, Korea, China, Brazil, and India. Brazil, one of the world’s largest livestock markets, is beginning to produce startups, though many are focused on pet diagnostics and therapeutics rather than livestock.

2. Success Still Means Getting Acquired, but the Playbook Is Starting to Change

At this stage in the industry’s development, success for an animal health startup overwhelmingly means one of two things: being acquired by a Big 4 company (Zoetis, Boehringer Ingelheim, Merck Animal Health, Elanco) or securing a commercial partnership with one.

But Harvey sees that model evolving. Companies like Loyal (pet longevity, which has raised over $100 million) and Exton (companion animal therapeutics) are explicitly building their own commercial operations rather than positioning for acquisition. Loyal has stated publicly that it intends to handle sales and marketing itself. Exton has built a physical facility in Massachusetts and staffed up well beyond the typical two-person startup.

Harvey also pointed to an alternative exit model: TriviumVet, an Irish startup acquired by PBI Gordon (a holding company that also owns Pegasus Laboratories). That deal showed that you don’t have to sell to a Big 4 company to get your product to market, even if the global scale question remains open.

On the livestock technology side, the dynamics are different. Companies like Halter and Targan have raised hundreds of millions and are already commercializing, but they tend to dominate regional markets (Australia, parts of Europe) rather than operating globally. There are simply fewer potential acquirers for livestock tech startups, which may push more of them toward independent growth.

3. The Startups That Gain Traction Share a Common Thread: Industry Connections

When Harvey evaluates a new startup, his first filter is the pitch. If he doesn’t understand what a company does within the first 30 seconds, his interest drops. But beyond the pitch, the strongest predictor of traction he’s observed is connection to the animal health industry.

Specifically, he looks at advisory boards. If a startup he doesn’t recognize has board members with backgrounds at Zoetis, Merck, Elanco, IDEXX, or Boehringer, Harvey treats it as a stamp of approval. Not that the product will work, but that there’s a viable market for it. That distinction matters: interesting science doesn’t always translate to a viable product.

Harvey also noted a growing trend of talent moving between startups and incumbents. Former startup executives are taking roles at Big 4 companies, and experienced commercial leaders from large organizations are becoming startup CEOs. That cross-pollination, as he described it, brings operational credibility to startups and entrepreneurial energy to established players.

4. One High-Profile Failure Can Cool an Entire Category

Because the animal health startup ecosystem is still small and interconnected, the failure of a single well-funded company sends outsized signals to investors.

Harvey pointed to PetDx, a pet cancer diagnostics company that raised significant capital and then went bust. That single failure set back the entire pet cancer diagnostics category for years. Other companies in the space were affected even though their technology was different, because outside investors read the failure as a signal about the category, not just the company.

In human health, startups fail after raising large sums regularly. The industry absorbs it. Animal health can’t absorb failures the same way because the pool of potential investors is so much smaller. One bad experience can cause an investor to skip the space entirely for years.

The flip side is equally powerful. Harvey identified Loyal as the current bellwether for the industry. If Loyal succeeds, particularly if it becomes the first billion-dollar animal health startup exit, it could bring a wave of human health investors into animal health for the first time. If it fails, the consequences could extend well beyond pet longevity into companion animal therapeutics broadly.

5. The Investor Gap Is Real, and It Cuts Both Ways

Harvey was direct about the funding landscape: 90% of the startups he talks to say there isn’t enough funding for animal health companies. And while 2026 has seen some large individual deals (Loyal’s $100M+ round, Halter and Targan raising hundreds of millions), the aggregate funding picture is more nuanced. There are more deals happening, but many are small. The total capital flowing into animal health startups hasn’t grown proportionally to the number of companies.

The structural challenge is that very few human health investors have a mandate to invest in animal health. They’ll occasionally take an animal health deal as an alternative opportunity, and if it doesn’t work out, they don’t come back. On the agricultural side, investors with ag-tech or food sustainability mandates are more consistent, which is why livestock-focused startups sometimes have an easier time raising capital than companion animal companies.

The companies that have raised big rounds tend to share one trait: they attracted capital from outside the traditional animal health investor base. Pet-focused startups attract human health investors. Livestock tech attracts ag investors. Staying within the animal health funding ecosystem alone is limiting.

6. Vet Schools Are an Untapped Startup Pipeline

When the conversation turned to where the next wave of startups might come from, Harvey identified an underexploited source: veterinary schools.

He cited Ghent University in Belgium, which is actively trying to help its PhD students recognize when their research has commercial applications. But this remains the exception. Harvey noted that he writes about university research constantly, and most of it disappears after publication. Researchers produce the work as part of their academic progression and never consider whether it could become a business.

The opportunity runs in both directions. Startups need the infrastructure and early-stage validation that vet schools can provide (small studies, proof-of-concept work, access to clinical populations). And vet schools are sitting on research that could seed the next generation of animal health companies. The connection between the two remains underdeveloped, and the people coming through these programs could be the C-suite leaders of major animal health companies in ten years.

The Audience Questions That Mattered Most

With 5 audience questions answered live during the session, several threads added depth beyond the main takeaways.

Are investors interested in animal health CROs?

Harvey and host Tommy Jackson walked through the recent consolidation: KKR’s acquisition of Argenta and subsequent buying spree (MVS, Cliffabet, Patchy’s Group), plus private equity activity in distribution (Covetrus merging with MWI) and contract manufacturing. The pattern is clear: private equity sees animal health service companies as small assets that could be bigger. Whether there are enough remaining independent CROs for another wave of consolidation is less certain.

Can companion animal startups commercialize directly, like rare disease companies in human pharma?

Harvey sees this as an emerging possibility. The fact that companies like Loyal and Exton are building their own commercial infrastructure is new for the industry. TriviumVet’s path through PBI Gordon showed a middle option between selling to a Big 4 company and going it alone. But the fundamental challenge remains: it takes a sales force, regulatory expertise, and distribution networks to sell products globally, and no animal health startup has done that independently yet.

What should a startup focus on to succeed in veterinary oncology?

Harvey acknowledged the category has been perpetually “coming in the next decade.” The most notable signal: Zoetis now includes the word “oncology” on its forward-looking pipeline materials. That may seem small, but it suggests the largest animal health company sees enough potential to publicly commit resources. The category needs a trigger event, either a startup acquisition or a product launch, to attract the follow-on investment that creates real momentum. PetDx’s failure set the diagnostic side back, but therapeutic oncology remains wide open.

Are investors getting fluent in both human and animal health valuations?

Not yet. Startups developing molecules with dual human/vet indications are running into friction because human health and animal health investors have fundamentally different valuation frameworks. Loyal is the closest example of a company bridging both worlds (human health investors funding a pet-only company), but Harvey doesn’t see many investors with mandates that explicitly include animal health alongside human biotech. That gap persists.

What This Means for the Industry

The animal health startup ecosystem has reached a scale that would have been unimaginable a decade ago. But scale and maturity are different things. The industry is still working out basic questions: What does a successful independent animal health startup look like? Can any new entrant build a global commercial presence without selling to an incumbent? Will outside investors develop the fluency and patience to repeatedly fund animal health companies?

Harvey’s central observation is that the next two to three years will answer these questions. The companies that raised heavily during the recent funding wave are approaching commercialization decisions. Whether they succeed independently, get acquired productively, or fail visibly will shape the investment climate for a generation of startups behind them.

For R&D leaders, business development teams, and strategy executives at animal health companies of all sizes, the practical implications are clear: the startup pipeline is a real source of innovation. The companies that build relationships with startups early, whether through advisory roles, pilot partnerships, or commercial agreements, will have the best view of what’s coming and the first opportunity to act on it.
