Feb 2025Series A-$5MAmbAgon Therapeutics is a biotechnology company spun off from Eindhoven University of Technology (TU/e) that focuses on drug discovery using 14-3-3 protein biology. The company has developed a modular platform for stabilizing naturally occurring 14-3-3 protein-protein interactions to create therapeutic candidates for targets traditionally considered difficult to treat with drugs, with an initial pipeline focused on oncology. In July 2025, AmbAgon Therapeutics raised a Series A funding round worth $85 million, led by Nextech Invest. The round included participation from prior seed investors including RA Capital Management, Droia Ventures, Inkef Capital, AbbVie Ventures, MRL Ventures Fund, and Mission BioCapital, along with new investor Surveyor Capital (a Citadel company). Since its seed funding, the company developed a proprietary dataset and systemic understanding of 14-3-3 interactions, positioning the platform to address previously undruggable targets.

The company's pipeline at the time focused on oncology, with the goal of developing therapeutic candidates across cancer, metabolic disorders, neurodegenerative diseases, and infectious diseases. As of January 2022, Ambagon employed approximately 20 people with half based in Eindhoven and half in San Francisco, and planned to double its Eindhoven workforce with the new capital. The company had previously raised an $18 million seed round in July 2020 and was at the pre-clinical development stage, with no marketed products or disclosed revenue at the time of the Series A.

The platform enables rapid development of novel therapeutics for high-value targets in oncology, with potential expansion to metabolic disorders, neurodegenerative, and infectious diseases. Founded by experts from UCSF and TU/e, including Michelle Arkin, Luc Brunsveld, and Christian Ottmann, the company is based in San Francisco with ties to Eindhoven. On January 6, 2022, Ambagon announced an $85 million Series A financing round led by Nextech Invest, with participation from seed investors RA Capital Management, Droia Ventures, Inkef Capital, AbbVie Ventures, MRL Ventures Fund, and Mission BioCapital, plus new investor Surveyor Capital (a Citadel company). This followed an $18 million seed round in July 2020, bringing total funds raised to $103 million. The Series A proceeds are designated to augment the drug discovery platform, advance an initial pipeline of five oncology-focused projects toward clinical candidates, and add new projects beyond cancer. Leadership includes CEO Scott Clarke, formerly of Tizona and Trishula Therapeutics, CSO Nancy Pryer from Day One Biopharmaceuticals and Nurix, and Chair Adam Rosenberg from RA Capital. The company aims to nominate a development candidate in 2023 and enter the clinic in 2024, leveraging proprietary datasets on 14-3-3 interactions to create first-in-class drugs for targets like p53, FOXO, Raf kinases, tau, alpha-synuclein, and LRRK2.
