Nunatak Biotech June 2025 Venture - Series Unknown Funding Round

Nunatak Biotech was founded in 2023 by a multidisciplinary team led by Julia Mensa (CEO) and María Martha Martorell (COO), based in Buenos Aires. Emerging from the innovation ecosystem of the University of Buenos Aires, the company is dedicated to developing bioinputs based on extremophile microorganisms -collected in places such as Antarctica- to improve the resilience and health of degraded agricultural soils.

The most recent round of investment took place in June 2025, when Nunatak was selected as one of five Spanish-speaking startups to participate in Eatable Adventures' Raíces program, receiving US$107,000 as part of a joint initiative with other agrifoodtech startups.

Nunatak intends to invest in strengthening its bioremediation technology platform, accelerate field trials in regions affected by degradation or salinity, and deepen plant-microbe integration with a focus on crops such as wheat and barley. These uses are based on its model of microbes designed to restore distressed agricultural soils.

The support of Eatable Adventures, through the Raíces program, is relevant because it combines seed capital with technical mentoring and access to international networks. This support is important both to validate their technologies outside Argentina and to accompany their scalability in a market that demands regenerative solutions. The program also offers access to future funding, up to €1 M, which opens up the possibility of later stages of financing for Nunatak.

Nunatak's approach is based on a biotechnology platform that maps optimal associations between plants and microorganisms in extreme environments, utilizing environmental, soil, and metagenomic data. It applies these models in seed treatments or plant bioinputs that enhance germination, resistance to water stress or salinity, and, in turn, promise to reduce dependence on conventional chemical fertilizers.

“The experience we have acquired over the years in the Foodtech sector gives us a complete and accurate view of the ecosystem, which has allowed us to select and invest in the startups with the greatest development potential and that fit the needs of the sector,” commented José Luis Cabañero, founder and CEO of Eatable Adventures. “Incorporating technology and innovation is essential to increase production, optimize resources, and reduce the environmental footprint of the food system.”

The impact of the international backing transcends the capital received: it enhances Nunatak's visibility and credibility with potential customers, regulators, and corporate partners, intensifying its purpose of restoring soils and fostering agricultural systems that are more resilient to climate change. In a global context marked by land degradation, Nunatak's innovation, backed by an accelerator with a European and Latin American presence, strengthens local capabilities with international reach, providing scientific and sustainable solutions for the agricultural future.
