Boundless Bio Funding Rounds

DateStageRaised FromRaisedValuationRev. MultipleDeal Summary
May-23Series CLeaps by Bayer; RA Capital Management$100MBoundless Bio is a clinical-stage precision oncology company developing therapeutics targeting extrachromosomal DNA (ecDNA) in oncogene-amplified cancers, which affect patients resistant to standard targeted therapies and immunotherapies. The company launched in 2019 with a $49 million Series A led by Arch Venture Partners and City Hill Ventures, followed by a $105 million Series B in April 2021, and closed an oversubscribed $100 million Series C on May 16, 2023, co-led by Leaps by Bayer and RA Capital Management. New investors included Sectoral Asset Management and Piper Heartland Healthcare Capital, alongside existing backers like Arch Venture Partners, Vertex Ventures, Alexandria Venture Investments, and others. Proceeds from the Series C will advance BBI-355, the first ecDNA-directed therapy (ecDTx) and a Chk1 inhibitor, through Phase 1/2 clinical readouts in the POTENTIATE trial for oncogene-amplified cancers including non-small cell lung cancer, breast cancer, and head and neck squamous cell carcinoma. The trial tests BBI-355 as monotherapy and in combinations; the first patient was dosed shortly before the financing announcement. Funds will also support preclinical candidates and the ECHO clinical trial assay. Boundless estimates its therapies could address around 400,000 patients lacking effective options. Leaps by Bayer highlighted the potential to tackle oncogene-amplified cancers, a major unmet need. Post-IPO in 2024, RA Capital converted Series B and C preferred stock to common on a 19.5-for-1 basis and bought additional shares, with market cap at $299.1 million USD as of a later date.
Apr-21Series BNextech Invest; RA Capital Management$105MBoundless Bio is a San Diego-based precision oncology company developing therapeutics directed against extrachromosomal DNA (ecDNA) in aggressive, oncogene-amplified cancers. The company raised $105 million in a Series B financing round on April 28, 2021, led by RA Capital Management and Nextech Invest. Since inception, Boundless Bio has raised a total of $252.1 million from leading life science investors including ARCH Venture Partners, Fidelity Management & Research Company LLC, RA Capital Management, Leaps by Bayer, Nextech Invest, and Vertex Ventures HC, among others. The Series B was part of multiple funding rounds, with subsequent financings including a $100 million oversubscribed Series C in 2023 co-led by Leaps by Bayer and RA Capital Management, featuring participation from existing investors like Nextech Invest. Boundless Bio advanced to an IPO on March 28, 2024, raising $100 million on NASDAQ under ticker BOLD at an implied valuation of $490 million, with total funding reaching approximately $299.63 million over seven rounds. The company focuses on pioneering ecDNA-directed therapies (ecDTx), with lead candidate BBI-355, a checkpoint kinase 1 (CHK1) inhibitor, advancing through Phase 1/2 clinical trials.
Sep-19Series AAlexandria Venture Investments; ARCH Venture Partners; Boxer Capital; City Hill Ventures; GT Healthcare Capital Partners; Vertex Ventures$46MBoundless Bio is a biopharmaceutical company founded in 2018 that focuses on understanding and targeting extrachromosomal DNA (ecDNA) in aggressive cancers. The company aims to develop a new class of cancer therapeutics by identifying and characterizing ecDNA-driven tumors and exploiting the unique vulnerabilities of this DNA architecture, targeting cancers with high copy number focal gene amplifications that have historically been difficult to treat. In September 2019, Boundless Bio announced its Series A funding round of $46.4 million, co-led by ARCH Venture Partners and City Hill Ventures, with participation from Vertex Ventures, GT Healthcare Capital Partners, Boxer Capital of the Tavistock Group, Alexandria Venture Investments, and several undisclosed investors. The company planned to use the funding to solidify its leadership in ecDNA biology by building technology to identify and characterize ecDNA-driven tumors, validating novel cancer targets, and developing targeted treatments. At the time of the Series A announcement, Boundless Bio had a team of approximately 15 people and was based in San Diego's Torrey Pines biotech hub, with founder Paul Mischel, M.D., and CEO Zachary Hornby leading the company's drug discovery efforts across three strategic buckets: targeting the enzymatic machinery required to excise DNA off chromosomes, blocking metabolic pathways involved in ecDNA formation, and inhibiting DNA damage repair pathways that ecDNA depend on for survival.
