Announcing Spring: a Venture Studio and Fund for Animal Welfare Tech

Why building and backing Welfare Tech companies may be one of the most promising things we can do for billions of animals.

I used AI to assist in writing this post, but I’ve rewritten it extensively and endorse it.

1. Why we built Spring

I’m Eitan, a long-time EA who spent most of a decade working on turning cultivated meat from an idea into a real field, including founding Mission Barns. Now, I’ve teamed up with Milo Runkle — co-founder of the Good Food Institute, New Crop Capital, Joyful Ventures, among other groups — to found Spring Innovation Fund, together with Nate Crosser, who spent years as an agtech and biotech VC.

Welfare Tech is technology that improves the lives of animals in ways that make commercial sense for producers. The category spans preventing harm (e.g. in-ovo sexing, better genetics, vaccines against painful diseases); detecting and improving welfare (e.g. AI-enabled monitoring paired with treatment); enabling accountability (e.g. welfare traceability, analytics, & compliance infrastructure); and accelerating adoption (e.g. tools that make higher-welfare systems the productive default).

In conversations with over a dozen groups in the space, we’ve collated 100 “white spaces” where a welfare intervention is scientifically plausible and commercially unaddressed.1 That number only scratches the surface: for nearly every farmed species there are many different welfare areas waiting for someone to address. Our vision is an entire ecosystem: a field as serious and well-staffed as alt-protein, with top-caliber researchers, engineers, and entrepreneurs choosing to build Welfare Tech.

This isn’t a new idea so much as a newly growing one. Pioneering nonprofits like Shrimp Welfare Project and Innovate Animal Ag2 have realized the potential of Welfare Tech to transform their industries. In his recent posts, Aaron Boddy argues that the animal welfare movement is too passive, waiting to see what industry builds and then campaigning for its adoption, rather than building the tech it wants itself.3 Spring is, in part, an attempt to put capital and company-building experience behind that thesis. Beyond building and backing companies, we see a coordinating role to play here: centralizing and fostering cooperation between actors with deep on-the-ground knowledge, to drive innovation.

Consider in-ovo sexing as an example of what a healthy Welfare Tech ecosystem looks like. Around 7 billion male chicks are culled every year, ground up soon after hatching because they cannot lay eggs. In-ovo sexing identifies an embryo’s sex before it hatches, so male eggs are never incubated to term. What began as an idea is now a competitive landscape of companies pursuing different technical approaches, from hyperspectral imaging to PCR screening, and that competition keeps pushing costs down. Adoption has gone from pilot to mainstream across much of Europe, and it is now gaining ground in the U.S., Brazil, and Australia, with Walmart and other major buyers signaling a shift. Across dozens of welfare problems, we would love to see a cluster of companies racing to build the best solution, buyers and regulators creating the pull, and the standard of care ratcheting upward year over year.

2. Why Welfare Tech is high-impact

Several things make us think Welfare Tech is unusually high-leverage:

3. Why for-profit companies?

Spring is a nonprofit, but what we build and back are primarily for-profit companies. Philanthropy’s real job here is to catalyze markets that can then run on their own legs. Technological innovation in legacy industries often happens slowly or not at all, especially around challenging issues like animal welfare. But once someone gets them started they can pay for themselves and scale without a permanent subsidy.

4. Objections

Here are the strongest objections we hear, and how we think about them.

5. Who Spring is for

Spring will resonate with you if you think welfare improvements at scale genuinely matter; if you give real weight to aquatic and other small, numerous animals; if you’re temperamentally techno-optimist; and if you think the movement should build scalable vehicles ahead of the money rather than waiting for it. It probably won’t resonate if you think only efforts to end or replace animal agriculture count as progress, if you’re confident AI or alt-proteins will solve this (or render it irrelevant) within a few years, or if you object to directing philanthropic funding toward for-profit vehicles in this space.

Spring runs three programs:

Thanks to the many people across the Welfare Tech landscape who have spoken with us and whose work is pioneering the space, including Shrimp Welfare Project, Aquatic Life Institute, Myrias, Rethink Priorities; as well as other EA Forum posters whose feedback helped shape this.

I'm excited to see this happen! Some welfare tech ideas seem really promising, and I think this is clearly a promising project — it's great that it's happening.

My biggest areas of uncertainty about welfare tech (which overlap with some you flagged and some of which apply to only some technologies):

Thanks so much for doing this! Seems like a great thing to try, and exciting to see the technology that will come out of it!

Thanks for the write up, Eitan. A venture philanthropy fund as an animal welfare megaproject has been top of mind for me for years. Your strategic thinking (and Milo's) refined the concept into something uniquely catalytic. Grateful to work on Welfare Tech alongside you and the other great orgs in this field.

Hi Eitan. Thanks for sharing. I am enthusiastic about this initiative.

Its impact is more direct — same animals, better lives. Many animal-welfare interventions can be contested based on their indirect or secondary effects, such as how a diet shift ripples through wild-animal populations, say, or whether a reform just moves production elsewhere. Welfare Tech is comparatively straightforward: it improves the lives of animals already being farmed anyway.

I think interventions improving the lives of farmed animals may increase or decrease the welfare of soil invertebrates much more than they increase the welfare of farmed animals.

I see no escape from the uncertainty about the effects on soil invertebrates if one wants to increase welfare while accounting for all animals. I am not aware of any intervention supported by impact-focussed funders with effects on soil invertebrates robustly smaller than those on the target beneficiaries. Not saving human lives, not decreasing the consumption of animal foods or ingredients, not replacing fast with slower growth chicken, not replacing layers in battery cages with ones in cage-free aviaries or barns, not replacing standard with bird-safe glass, not replacing rodenticide with fertility control bait, and not even electrically stunning farmed shrimps.


 

It’s cost-effective, and the economics compound. Take shrimp stunners, estimated to help on the order of 1,400–1,500 shrimp per dollar per year.5 On a welfare-adjusted basis, some analyses (admittedly controversial) found it arguably ~100× more cost-effective than cage-free corporate campaigns, which are estimated at 9–120 chicken-years per dollar. Those multiples lean on moral-weight assumptions for shrimp and pain during death; but even discounted, they’re remarkable.

It would be better to argue for high cost-effectiveness comparing interventions targeting similar species (with one intervention involving welfare tech)? Otherwise, the results of the comparisons will be influenced a lot by the uncertainty in welfare comparisons across species. I have practically no idea about whether the Shrimp Welfare Project’s (SWP’s) Humane Slaughter Initiative (HSI) has increased the welfare of shrimps more or less cost-effectively than cage-free egg corporate campaigns increase the welfare of chickens. I estimated HSI has increased the welfare of shrimps 139 times as cost-effectively as cage-free egg corporate campaigns increase the welfare of chickens. However, for sentience-adjusted welfare ranges proportional to "individual number of neurons"^"exponent", and "exponent" from 0 to 2, which covers the best guesses that I consider reasonable, I calculate that HSI has increased the welfare of shrimps 2.26*10^-4 to 1.49 k times as cost-effectively as cage-free egg corporate campaigns. interventions increases the welfare of their target beneficiries more cost-effectively. Below is a graph with the results for "exponent" from 0 to 2.

I am excited to hear this! I worked at Mercy for Animals when Milo was still there. I want to say that he is a true visionary and doer!
