Mammoth Biosciences has raised $303.1M across 6 funding rounds. Most recently, it raised $40.0M Other Equity in January 2022.
Mammoth Biosciences is a biotechnology company developing ultracompact CRISPR systems for in vivo gene editing therapies targeting life-threatening diseases, alongside diagnostics applications.[1][3][4] Founded in 2017, it focuses on curative treatments by enabling precise editing in hard-to-reach tissues using modalities like base editing, gene writing, and epigenetic editing, serving patients with genetic disorders and partnering with pharma giants.[1][2][4] The company has raised over $195 million, achieving unicorn status in 2021 via a $150 million Series D, with 190 employees and a pipeline including lead candidate MB-111 for liver triglyceride regulation.[1][2][4]
Its growth momentum includes preclinical advancements, such as presenting MB-111 data at the 2025 ESGCT Congress, DARPA and NIH funding for multi-pathogen diagnostics, and a GSK partnership for rapid COVID-19 tests, positioning it as a CRISPR leader against competitors like CRISPR Therapeutics and Intellia.[1][2][4]
Mammoth Biosciences was founded in 2017 by CRISPR pioneer and Nobel laureate Jennifer Doudna, alongside Trevor Martin, Janice Chen (current Co-founder and CTO), and Lucas Harrington.[1][3][4] Doudna's groundbreaking work on CRISPR-Cas9, which earned her the 2020 Nobel Prize in Chemistry, inspired the venture to expand beyond traditional systems.[1][2] The idea emerged from identifying nature's diverse CRISPR enzymes to create smaller, more versatile tools for in-body editing, addressing limitations of bulkier Cas9 proteins.[1][4]
Early traction came swiftly: by 2021, it secured unicorn valuation with $195 million in funding, including Amazon's participation, and government grants for diagnostics like 20-minute COVID tests and multi-pathogen detection.[2] Pivotal moments include partnerships with GSK and pharma leaders, building a robust IP portfolio from deep science expertise.[1][2][4]
Mammoth rides the CRISPR therapeutics wave, transforming genetic medicine from ex vivo edits to scalable in vivo cures amid rising demand for one-time treatments for diseases like hypertriglyceridemia.[2][4][6] Timing aligns with maturing delivery tech (e.g., lipid nanoparticles) and regulatory progress, fueled by post-Nobel validation and AI-aided protein engineering.[1][2] Market forces favor it: exploding gene therapy funding, diagnostics needs from pandemics, and competition pushing innovation, with Mammoth's compact systems offering packaging advantages.[1][2]
It influences the ecosystem by licensing tech, partnering with big pharma, and advancing diagnostics, accelerating CRISPR's shift from hype to clinic while challenging incumbents through biodiversity-sourced enzymes.[1][4][5]
Mammoth is poised for clinical milestones, with MB-111 preclinical data signaling 2026+ trials and pipeline expansion into more indications via partnerships.[4] Trends like advanced delivery, multimodal editing, and AI-protein design will amplify its edge, potentially yielding first approvals amid a $100B+ gene therapy market.[1][2] Its influence may evolve from platform pioneer to category leader, unlocking CRISPR's full promise for millions—echoing Doudna's vision that began with biological scissors now reshaping human health.[6]
