| Date | Stage | Investors | Raised | Deal Summary |
|---|---|---|---|---|
| Dec 2025 | Series B | Ascenta Capital (lead); Bessemer Venture Partners (lead); Pfizer Venture Investments; YK Bioventures; Invus; Atlas Venture; Lightspeed Venture Partners; RA Capital Management; Surveyor Capital; Regeneron Ventures; Finchley Healthcare Ventures | $120M | TRIANA Biomedicines, a biopharmaceutical company based in Lexington, Massachusetts, closed an oversubscribed $120 million Series B financing round on December 3, 2025. The round was co-led by Ascenta Capital and Bessemer Venture Partners, with participation from new investors YK Bioventures, Regeneron Ventures, Invus, and Finchley Healthcare Ventures. Existing investors including RA Capital Management, Atlas Venture, Lightspeed Venture Partners, Pfizer Ventures, and Surveyor Capital continued their support. Lorence Kim, M.D. from Ascenta Capital and Andrew Hedin from Bessemer Venture Partners joined the company's board of directors as part of the financing. TRIANA Biomedicines operates a target-first and proximity-first molecular glue discovery platform focused on developing targeted protein degradation therapies for difficult-to-treat cancers. The company's lead program, TRI-611, is an anaplastic lymphoma kinase–positive (ALK) targeted molecular glue degrader designed to address ALK-positive non-small cell lung cancer (NSCLC) and overcome resistance and tolerability challenges seen with current ALK inhibitor therapies. The Series B proceeds will fund the advancement of TRI-611 toward clinical proof of concept, selection of a second development candidate in 2026, and broader maturation of TRIANA's molecular glue pipeline. As a preclinical and early clinical stage biotech company, TRIANA Biomedicines has not publicly disclosed revenue, ARR, EBITDA, or post-money valuation figures. |
| Apr 2022 | Series A | Atlas Venture (lead); Lightspeed Venture Partners (lead); RA Capital Management (lead); Pfizer Venture Investments; Logos Capital; Surveyor Capital | $110M | Triana Biomedicines launched publicly on April 6, 2022, with $110 million in Series A funding to develop a molecular glue discovery platform for treating diseases with undruggable or inadequately addressed targets. The Boston-based biotechnology company was co-founded by Jesse Chen (who previously worked at targeted protein degradation firm Kymera Therapeutics) and other scientific leaders, with Patrick Trojer joining as President and CEO in November 2021. The Series A was co-led by Lightspeed Venture Partners, RA Capital Management, and Atlas Venture, with participation from Pfizer Ventures, Surveyor Capital (a Citadel company), and Logos Capital, with several investors taking board seats. Triana's platform uses high-resolution structural insights, AI, and computational tools to identify and prioritize E3 ubiquitin ligases and design rational molecular glue candidates, capable of evaluating more than 600 known E3 ligases for disease-relevant targets. The company emerged from stealth with this funding to establish a best-in-class, scalable platform focused initially on inducing or enhancing degradation of cancer targets, with the molecular glue approach potentially fundamentally changing small molecule drug discovery paradigms. |
| Feb 2022 | Undisclosed stage | - | $35M | Triana Biomedicines is a biopharmaceutical company developing a target-first, rational molecular glue discovery platform to create novel small molecules that induce protein-protein interactions for targeted protein degradation, primarily in oncology. The company launched publicly on April 6, 2022, with $110 million in total funding, including a Series A round co-led by Lightspeed Venture Partners, RA Capital Management, and Atlas Venture, with participation from Pfizer Ventures, Surveyor Capital, and Logos Capital. Prior seed funding came from RA Capital and Atlas Venture, and a $34.8 million raise was filed in February 2022. In December 2025, Triana closed an oversubscribed $120 million Series B financing co-led by Ascenta Capital and Bessemer Venture Partners, with new investors YK Bioventures, Regeneron Ventures, Invus, and Finchley Healthcare Ventures, plus existing supporters. Proceeds fund advancement of lead asset TRI-611, an ALK-targeted molecular glue degrader for ALK+ NSCLC, to clinical proof-of-concept, selection of a second candidate in 2026, and pipeline expansion including breast and colorectal cancer programs. Pfizer, an earlier investor, has a collaboration for molecular glue degraders with a $49 million upfront payment. The company remains pre-clinical, focused on undruggable targets in cancer, amid growing interest in degrader medicines from firms like Roche, AbbVie, Lilly, and Gilead in 2025. |
| Sep 2021 | Series A | - | $10M | Triana Biomedicines launched publicly in April 2022 with $110 million in series A funding co-led by Lightspeed Venture Partners, RA Capital Management, and Atlas Venture, following seed investments including a $15 million seed in September 2024 and prior seed from RA Capital and Atlas Venture. The company develops a target-first molecular glue discovery platform to identify optimal E3 ubiquitin ligases for disease targets, enabling rational design of molecular glues that induce protein degradation for undruggable targets. Patrick Trojer joined as president and CEO in November 2021 to lead funding and development efforts. Subsequent rounds included a $49 million Series A-II in October 2024 and a $120 million oversubscribed Series B in December 2025 co-led by Ascenta Capital and Bessemer Venture Partners to advance lead ALK degrader TRI-611 to clinical proof-of-concept in ALK+ NSCLC and expand the pipeline. Investors across rounds include Pfizer Ventures, Surveyor Capital, and Logos Capital, with total funding reaching approximately $175 million to $295 million over multiple rounds. |
