- Triple Bio
Participated · Seed · May 2026
Triple Bio is developing next-generation lipid ingredients for livestock feed aimed at improving feed efficiency, increasing milk production and lowering enteric methane emissions. The company’s technology focuses on lipid-based feed additives designed to simultaneously target yield and methane reduction. Its founding team combines expertise in microbiology, animal science, dairy and industrial biotechnology. Triple Bio recently raised a €1.5M pre-seed round from Marble, Nucleus Capital, Positron and Climate Club to advance development. The startup is tied to the Leiden region and is using early backing to accelerate its progress.
- AtmoCooling
Participated · Seed · Mar 2025
AtmoCooling develops a proprietary seawater evaporative cooling system that lowers ambient temperatures to create optimized microclimates for agriculture and sustainable development. The system leverages brine and seawater instead of freshwater, offering a scalable, sustainable alternative to traditional cooling methods and reducing heat stress on crops, infrastructure, and communities. The company is advancing pilot deployments in key arid regions and expanding partnerships with researchers, agricultural producers, and sustainability innovators. Led by CEO Paul Mahacek and headquartered in Seattle, WA, AtmoCooling intends to use recent funding to expand operations and grow its business reach. The article does not disclose revenue or user metrics.
- Aerleum
Participated · Seed · Oct 2024
Aerleum is developing a technology to capture and valorize CO₂ rather than treating it solely as an emission to be removed. Its current flagship effort, DEMO_ONE, is being deployed in the Bouches‑du‑Rhône region, within the industrial Fos‑Berre basin. The company aims to demonstrate industrial potential there and to prepare the technology for commercial deployment at larger scale. The recent €4.8 million financing is meant to advance deployment of DEMO_ONE and bring the project closer to broader use. Reporting does not provide details on capture capacity, project cost, Aerleum’s equity stake, revenues, or employee impact.
