Myelin VC

Myelin VC is a venture capital firm founded in 2019 with operations across Madrid, Spain, Montevideo, Uruguay, and Buenos Aires, Argentina. The fund's name references the myelin sheath that accelerates neural signals, and its mission centers on backing startups whose ideas reshape how people think, collaborate, and solve problems at scale. Myelin is a $50 million fund that takes an industry-agnostic approach to early-stage technology, writing checks of $250,000 to $1 million from seed through Series A. The team is led by General Partners Matias Nisenson (blockchain gaming and DeFi background), Martin Varsavsky (telecom and fertility entrepreneur), Cesar Levene, and Non-Executive General Partner Alec Oxenford (founder of OLX), with Investment Partner Federico Jack also involved in deal execution. As of November 2024 Myelin had invested in 42 companies spanning healthtech, biotech, food and beverage, SaaS, fintech, AI, and web3. Notable portfolio companies include CookUnity, a rapidly scaling food-tech platform; Daye, a women's health company founded by Valentina Milanova; Aura Biosciences, founded by Elisabeth de Los Pinos (an exit); Buenbit, a fintech founded by Federico Ogue; Pipedream Labs ($13 million round in 2024 alongside Starship Ventures and Cortado Ventures); NUE Life Health (an exit); Nodal ($4 million seed extension, November 2024); Throne (gut-health AI, May 2025); and Midas Software (most recent investment, March 2026). Three companies have exited to date. Myelin's tri-city presence across Madrid, Montevideo, and Buenos Aires anchors it as a genuinely transatlantic fund, with the ability to source from Spain's growing startup ecosystem and Latin America's deep pool of technical and commercial talent simultaneously.
