Alta Partners
Alta Partners was established in 1996 by Jean Deleage, Guy Nohra, Garrett Gruener and Marino Polestra. The four had previously worked together at Burr, Egan, Deleage & Co. They built the firm around a focused healthcare and life sciences mandate. The firm invests in early-stage companies across biotech, digital health and healthcare services. It has participated in financings for Allakos, Vir Biotechnology, Tyra Biosciences, Be Biopharma and eGenesis. Co-investors have included ARCH Venture Partners, Venrock, NEA, RA Capital and SoftBank Vision Fund. Activity spans North America with additional exposure through cross-border syndicates in Europe. Capital is deployed via dedicated venture funds and direct co-investments rather than broad fund-of-funds commitments. Alta Partners NextGen Funds total over $800 million across four vehicles launched since 2017. Pete Hudson and Bob More joined that year to lead the new series. The firm maintains its headquarters in New York. In March 2023 Alta Partners filed suit against Forge Global Holdings in the Southern District of New York. The firm operates as an independent venture manager rather than a captive family office. Its governance centers on the original founding partners and a small group of managing directors who maintain board seats at portfolio companies. This structure has produced repeated co-investment relationships with the same limited set of healthcare specialists over three decades.
