42 Startups Reinventing Industries

Sean O'Sullivan at SOSV

🇺🇸 North Carolina
Co-Founder and CEO: Kathryn Polkoff
Why: Cattle are responsible for about 30% of global methane emissions—one of the most powerful greenhouse gases. Hoofprint Biome uses enzymes to reshape the rumen microbiome, cutting methane production while boosting dairy milk yield and beef cattle weight gain. No harsh chemical feed additives. Only a natural solution.
🇺🇸 New Jersey
Co-Founder and CEO: Randy Allen
Why: Still Bright is developing a novel, sustainable method to extract copper without the massive waste, pollution, and energy demands of conventional mining. Its electrochemical process recovers high-purity copper directly from low-grade ores and waste streams, turning what’s normally discarded into value, unlocking cleaner, more efficient, circular metal production.
🇬🇧 Glasgow
Managing Director: David Harvey
Why: Xias Bio has developed the world’s first molecular platform for creating multi-functional, animal-free proteins. Each one can do the work of three or more animal proteins. Targeting cosmetics (e.g., collagen, keratin, elastin), its tech reduces reliance on livestock, slashes GHGs, pollution, and deforestation, paving the way for sustainable bioeconomy transformation.
SOSV x Endolith at HackSummit
Deborah Zajac of SOSV sits down with Liz Dennett CEO and Founder of Endolith for a fireside chat at the HackSummit in New York (10-11th December).

Laura Fox at Streetlife Ventures

🇺🇸 San Francisco
CEO: Tiffany Yeh, Jack Wilson
Why: 2024 was the hottest summer on record globally, and 2025 is on track to be on par. By 2030, extreme heat is expected to drive $2.1T in corporate asset loss annually (S&P), and extreme heat is already the leading cause of climate-related deaths (500K per year, with one-third in Europe). Eztia is a novel material science breakthrough that absorbs body heat and reduces skin temperature by ~10°C for 6-8 hours of strenuous physical activity, enhancing human performance, worker productivity, and protecting against heat-related injuries. Eztia’s technology can be used anywhere in the world, integrates into existing clothing and gear, and recharges with only water in under 30 minutes — no batteries, refrigeration, or electricity needed.
⚡️ Public Grid*
🇺🇸 New York
Co-Founder: Zach Schmitz, Joe Robbins
Why: More than a third of Americans feel burdened by energy costs, and 20% of renters have missed energy payments due to high costs — and renters on average pay 10% more for energy. Public Grid transforms how residents and multifamily properties interact with their electricity providers to reduce bills. Public Grid saves renters 10-30% on their utility bills while delivering clean energy through three business lines: energy brokering, low-cost delivery of community solar benefits, and virtual power plant programs (VPPs), which also help utilities optimize their grid infrastructure.
🔍 Silera
🇨🇦 Quebec
Co-Founder: Andrei Muresanu, Jerome Malevez
Why: Computer vision is 10 years behind, and large language models (LLMs) have 3,000x more labeled data than vision models – delaying important innovations to built world systems to lower costs and decrease emissions and waste. Silera generated photoreal synthetic data to scale vision models, to solve critical pain points for circular economy, resilient infrastructure, zero-waste manufacturing, and climate-smart agriculture use cases.
Matthew Blain at Voyager Ventures

❄️ Barocal
🇬🇧 Cambridge
Founder: Xavier Moya

⚡️ tem.
🇬🇧 London
CEO and Co-Founder: Joe McDonald
Why: tem is cutting out the middle men in the wholesale energy markets to provide low cost power to C&I customers.
❄️ Corintis
🇨🇭 Lausanne

Why: Corintis is scaling breakthrough microfluidic cooling technology for high-power chips in data centres.
Rachel Slaybaugh at DCVC

⚡️ Fervo Energy*
🇺🇸 Texas
CEO: Tim Latimer
Why: Clean, firm energy is incredibly important for grid reliability, clean air, and economic abundance. My whole career, geothermal was written of as a rounding-error power source that would never contribute meaningfully in most places. Fervo has torn down that assumption by making clean, firm geothermal energy viable and valuable in lots of locations.
🔌 Mainspring*
🇺🇸 California
CEO and Founder: Shannon Miller
Why: flexible, behind the meter power is key for businesses functioning on today's grid and Mainspring offers a power generation asset that fits that need. Mainspring's linear generators are fuel flexible, so they can bridge to a clean fuel future as well as use all of the renewable natural gas available today. Importantly, they are modular and flexible and can be built and scaled today.
🇺🇸 California
Ceo and Co-Founder: Lauren Dunford
Why: Reindustrialization means improving existing factories and building new ones that work with high efficiency. Guidewheel provides the sensors, intelligence, and operational tools to save energy, improve uptime, and drive performance in any factory. This crosscutting tool is driving value in factories and manufacturing.
DCVC x Brimstone at HackSummit
Rachel Slaybaugh, Partner at DCVC joins Cody Finke, Co-Founder of Brimstone for a fireside chat at the HackSummit in New York (10-11th December).
Together they’ll unpack Brimstone’s mission to transform heavy industry, starting with cement and how the scaleup process leverages the power of co-production and a carbon-free feedstock to deliver the same industry-standard products trusted by builders for generations.

Janelle Goulard at Pangaea Ventures

🇺🇸 New Jersey
Co-Founder and CEO: Sean Zheng
Why: The looming lithium supply gap and slow extraction cycles and tough economics facing brine pond operators are shaping up to present substantial hurdles in the drive for electrification. Princeton Critical Minerals’ novel “Lilypad” technology for evaporation ponds enables 2x faster evaporation and over 96% efficiency in solar energy conversion compared to conventional ponds, improving the economics and scalability of lithium production, and drastically reducing the time, land, and water needed per ton of lithium extracted.
🇺🇸 New Jersey
Co-Founder and CEO: Matthew Cheng
Why: The enormous untapped potential of the human microbiome is constrained by poor visibility into how microbial communities interact and influence health outcomes, leaving a multi-billion-dollar diagnostic and therapeutic opportunity largely unrealized. Kanvas Biosciences’ breakthrough HiPR-FISH spatial biology technology maps host-microbiome interactions in situ to unlock unprecedented insight into microbiomes in their native environment. The company’s integrated platform enables discovery, development and manufacturing of novel live biotherapeutics that will improve patients' response rates to immune checkpoint inhibitors for cancer treatment.
