Aug 2025Series BKinnevik (lead)$153M$550MStrand Therapeutics is a clinical-stage biotechnology company developing programmable mRNA therapies that integrate synthetic biology with genetic logic circuits for precise control in targeted cells, focusing on cancer and serious diseases. Its lead program, STX-001, is a self-replicating mRNA therapy delivering interleukin-12 (IL-12) into the tumor microenvironment, showing multiple RECIST responses including complete responses in Phase 1 trials for advanced solid tumors as of June 2025, with ongoing studies as monotherapy or with Keytruda. The pipeline includes STX-003, a systemically administered mRNA therapy with tumor-targeted IL-12 delivery, advancing toward Phase 1 in 2026. In August 2025, Strand raised $153 million in a Series B round led by Kinnevik with a $35 million investment, joined by new investors including Regeneron Ventures, ICONIQ, Amgen Ventures, Alderline Group, JIC-VGI, LG Technology Ventures, and Gradiant Corporation, plus existing backers like FPV Ventures, Playground Global, Eli Lilly, ANRI, and Potentum. This brings total funding to over $250 million, following a $97 million Series A in 2022. Ala Alenazi, Ph.D., from Kinnevik joined the board. The proceeds will support clinical advancement of STX-001, expansion of STX-003 into trials, and broader platform development for safer, more effective mRNA therapeutics. Early STX-001 data demonstrated systemic immune activation, anti-tumor responses across tumor types, and a favorable safety profile, validating the programmable RNA approach amid growing interest despite mRNA policy challenges. Strand, founded in 2017 by CEO Jake Becraft and Tasuku Kitada as an MIT spinout, positions programmable mRNA as the next frontier, with Kinnevik's Christian Scherrer highlighting outstanding clinical data and potential to reshape cancer treatment.
Nov 2024Undisclosed stageJIC--On November 22, 2024, JIC announced an equity investment in Strand Therapeutics through JIC Venture Growth Fund No. 2. The investing entity was JIC Venture Growth Investments, the JIC group manager responsible for direct venture, growth and listed-startup transactions, so the investment is attributed to the JIC investment house. Strand Therapeutics develops programmable messenger-RNA medicines using a synthetic-biology platform derived from research at MIT and Kyoto University. Its platform and internal pipeline are directed toward cancer and immune-cell applications and are supported by research and development partnerships. JIC VGI described the policy and investment rationale as an effort to support the development and commercialization of medical technologies and strengthen links between Japanese life-sciences research, clinical development and global markets. The transaction established JIC's direct investment relationship with the company and placed it within JIC VGI's Middle to Growth portfolio. JIC VGI said its capital and operating support would help Strand Therapeutics advance product development, commercialization, hiring, partnerships or market expansion in line with the company-specific plans described in the announcement. The official announcement identifies a share acquisition or subscription by the JIC-managed vehicle, giving the fund an equity position tied to the company's stated development and commercialization plan.
Nov 2022Series AFPV Ventures (lead); Potentum partners; Eli Lilly & Company Foundation; Playground Global$45M-Strand Therapeutics is a programmable mRNA company developing curative therapies for cancer and other diseases, founded in 2019 and headquartered in Boston, Massachusetts. The company's platform aims to create long-acting mRNA therapies that stimulate immune responses against tumors, positioning mRNA as a therapeutic modality beyond vaccines. In November 2022, Strand announced a Series A1 round adding $45 million in funding, bringing the total Series A to $97 million. The Series A1 was led by new investor FPV Ventures, founded by Wesley Chan (Google Analytics, Google Voice) and Pegah Ebrahimi (former COO/CIO at Morgan Stanley and COO of Cisco Collaboration). At this pre-clinical stage, Strand had not yet disclosed revenue, EBITDA, or other financial metrics. The company subsequently raised $153 million in a Series B round (2025) led by Kinnevik with participation from Regeneron Ventures, ICONIQ Capital, Amgen Ventures, and others, bringing total capital raised to over $250 million. By the 2025 ASCO meeting, lead asset STX-001 had demonstrated multiple RECIST responses in Phase 1 clinical data.
Jun 2021Series AANRI; Redmile Group; BeiGene; Camford Capital; Playground Global$52M-Strand Therapeutics, an MIT spinout founded in 2017 by leaders in mRNA-based synthetic biology, raised $52 million in an oversubscribed Series A round on June 23, 2021, led by Redmile Group, BeiGene, and Camford Capital, with participation from existing investors Playground Global and ANRI. This brought the company's total funding to $66 million, following a $6 million seed round in 2019 led by Playground Global. The proceeds were earmarked to expand its programmable mRNA platform and advance its lead drug candidate into Phase 1 clinical trials expected in early 2022, focusing on cancer immunotherapy and other diseases through self-replicating mRNAs with logic circuits for precise control of therapeutic activity in targeted tissues. Strand's platform develops next-generation mRNA therapeutics that sense cell-type specific signatures to enable controlled delivery of treatments, aiming for high efficacy and low toxicity in addressing solid tumors and life-threatening conditions poorly served by traditional therapies. The technology combines self-replication genes with synthetic biology logic, originating from MIT's Synthetic Biology Center research supported by DARPA, similar to early Moderna funding. A January 2021 BeiGene partnership included a $5 million investment rolled into this Series A.
Jun 2019SeedPlayground Global (lead); ANRI; Alexandria Venture Investments; Creative Destruction Lab (CDL)$6M-Strand Therapeutics, a biotechnology company developing gene therapies powered by synthetic biology, completed a $6 million seed financing round on June 4, 2019. The round was led by Playground Global with participation from Alexandria Venture Investments, ANRI, and private investors. Funds supported advancement of its programmable mRNA therapeutics platform for next-generation mRNA-based cancer immunotherapies.
