Gate Bioscience Overview

About Gate Bioscience

Gate Bioscience is a biotechnology firm developing Molecular Gates, a class of small-molecule drugs that target the Sec61 translocon to block secretion of disease-causing proteins like VEGF and TGFβ. This approach triggers intracellular degradation of targets, offering potential oral therapies for cancers and fibrotic diseases. The company's Sec61 platform integrates a library of gatekeeper molecules with secretion-focused assays and expertise in the secretory pathway. Headquartered in San Francisco, Gate Bioscience raised Series A funding in 2022 to advance its lead candidates into clinical trials.

Nov 2025Series BForbion Capital Partners (lead); GV; Versant Ventures; Andreessen Horowitz; Eli Lilly; ARCH Venture Partners$65M$161MGate Bioscience is a biotechnology company developing a novel class of small-molecule medicines called molecular gates, designed to eliminate disease-causing proteins at their source inside the cell. The company offers oral drug candidates targeting inflammatory and neurological diseases, positioning its approach as a pill-based alternative to injectable biologics. Gate Bioscience closed a $65 million oversubscribed Series B financing round on November 13, 2025, led by new investor Forbion Capital Partners B.V. The round included participation from new investor Eli Lilly and Company and existing backers Versant Ventures, Andreessen Horowitz Bio + Health, GV, and ARCH Venture Partners. This funding brought the company's total capital raised to approximately $135 million and valued the company at $161.0 million as of November 6, 2025. The Series B proceeds will fund advancement of Gate's lead molecular gate programs into clinical trials, expand its broader portfolio of molecular gate candidates, and strengthen its discovery platform. The company's platform has matured into a drug discovery engine enabling efficient generation of molecular gates for both internal development and partnerships with biopharma companies. Vanessa Carle, Principal at Forbion, joined Gate's Board of Directors as part of the transaction, bringing experience in scaling therapeutic companies across Europe and the United States.
Nov 2023Series AAndreessen Horowitz (lead); Versant Ventures (lead); GV; ARCH Venture Partners$60M-Gate Bioscience is a preclinical biotechnology company founded in 2021 and based in Brisbane, CA, developing a novel class of small molecule therapeutics called Molecular Gates. These drugs selectively bind to the secretory channel to block and degrade disease-causing extracellular proteins at their source inside the cell, targeting over 1,000 such proteins implicated in conditions like inflammation, neurodegenerative diseases, and cancers. The platform combines a proprietary library of Molecular Gates, secretion-focused assays, and insights into secretory pathway biology for high-throughput screening. In November 2023, Gate emerged from stealth with a $60 million Series A financing led by Versant Ventures and Andreessen Horowitz (a16z Bio + Health), with participation from ARCH Venture Partners and GV. The funds support advancing preclinical research, regulatory processes, platform expansion, and partnerships to move Molecular Gate medicines toward clinical stages. The company is led by experienced drug developers with track records in modalities like molecular glues, PROTACs, and covalent inhibitors. Gate has since raised a $65 million oversubscribed Series B in November 2025 led by Forbion with Eli Lilly and existing investors, bringing total capital to $135 million to fund IND-enabling studies, Phase 1 trials, and pipeline expansion in inflammation and beyond. In July 2024, Gate partnered with Eli Lilly in a deal worth up to $856 million in biobucks, including undisclosed upfront and equity for molecular gate programs.
