Company profile

researched Aug 2026

Rezo Therapeutics is a San Francisco-based biotechnology company that builds comprehensive maps of molecular disease networks in order to identify novel, druggable targets for precision therapeutics. Its "Sequence to Systems to Drugs" (SSD) platform integrates proteomics, genetics, structural biology, chemistry, and bioinformatics, combined with computational methods and artificial intelligence, to characterize disease-causing protein-protein, genetic, and biochemical interactions that the company says are difficult to detect with siloed, conventional approaches.

The platform is based on technology originating at the Quantitative Biosciences Institute (QBI) at the University of California, San Francisco. Rezo's initial therapeutic focus is solid tumor oncology, where it works to determine how mutations rewire cancer-driving networks in order to uncover tumor-specific targets, guide biomarker discovery for patient stratification, and develop mutation- and allele-specific precision medicines. The company has stated plans to expand into additional therapeutic areas through collaborations and partnerships. Its disease-specific maps are intended to support multiple treatment modalities, including small molecules that modulate protein activity.

Founding story

Rezo was founded by scientists associated with UCSF's Quantitative Biosciences Institute. Nevan Krogan, Ph.D., a UCSF professor, QBI director, and Gladstone Institutes senior investigator, developed the underlying integrated disease network mapping technology and served as co-founder and, at launch, chief executive officer. Additional co-founders named at launch include Kevan Shokat, Ph.D. (UCSF professor and HHMI investigator, known for work on KRAS-targeting chemistry), Sourav Bandyopadhyay, Ph.D. (UCSF professor and co-founder/chief scientific officer at launch), Natalia Jura, Ph.D. (UCSF professor and QBI associate director), George Scangos, Ph.D. (co-founder and board chair), and Norbert Bischofberger, Ph.D. (co-founder and board member). One third-party profile also lists Jacqueline Fabius among the co-founders and states the company was co-founded in 2022 by UCSF scientists.

Business model

Rezo operates as a therapeutics discovery and development company, using its proprietary platform to generate an internal pipeline of precision medicines rather than selling software or services. The company has stated it intends to explore additional therapeutic areas through collaborations and partnerships, indicating potential partnered development alongside proprietary programs.

No revenue is reported in the available sources; a financial data provider profile shows no disclosed revenue, EBITDA, or valuation figures for 2020-2024.

Traction

Disclosed traction consists primarily of the $78 million Series A at launch, assembly of a leadership team drawn from Intellia, Spark, Pfizer, Nurix, Dynavax, Merck, Octant, and Maze Therapeutics, and inclusion in BioSpace's 2024 lists of promising new biopharma companies. No clinical-stage programs, partnerships, or revenue figures are disclosed in the sources.

Latest developments

The most recent disclosed development is the appointment of Derek Hicks as chief executive officer, announced August 13, 2025. The company's website continues to advertise open roles.

Full profile — market position, technology, go-to-market, geography, history, risks & controversies

Market position

Rezo positions itself at the intersection of computational/AI-driven biology and precision oncology drug discovery, emphasizing network-level target identification over conventional single-target approaches. It is a private, venture-backed company; shares are listed on secondary marketplaces such as EquityZen and Nasdaq Private Market is referenced on its website.

Sources describe differentiation in the integration of multiple experimental technologies (proteomics, genetics, structural biology, chemistry) with computational analysis into a single platform, the identification of tumor-specific vulnerabilities and protein-protein interactions overlooked by conventional discovery, biomarker-guided patient stratification, and the company's origin in UCSF's QBI with a founding team of established academic and biotech leaders.

Technology

The Sequence to Systems to Drugs (SSD) platform integrates data from proteomics, genetics, structural biology, and chemical biology using computational methods, bioinformatics, and artificial intelligence to build maps of molecular disease networks. The maps are used to rapidly identify and study disease-causing protein and genetic interactions, including protein-protein interactions considered difficult to address with traditional methods, and to pinpoint targets that can be pursued with a range of treatment modalities such as small molecules.

Go-to-market

The company plans to advance an internal pipeline in solid tumor oncology and to expand into other therapeutic areas via collaborations and partnerships. The 2025 CEO appointment of a longtime business-development executive is described by a third-party profile as intended to drive partnerships and commercialization.

Ultimately patients with solid tumors guided by mutation and allele-specific biomarkers, with stated plans to address additional therapeutic areas; potential pharmaceutical collaborators and partners are also referenced.

Geography

Headquartered in San Francisco, California, United States; a third-party listing gives an address at 300 Mission Bay Blvd South, San Francisco, CA 94158, while another lists South San Francisco, CA. Scientific roots are at UCSF.

History

The company launched publicly on November 17, 2022 with a $78 million Series A financing. Leadership has since turned over: third-party sources describe Nadir Mahmood, Ph.D., previously of Nkarta, as an early CEO, with Derek Hicks appointed chief executive officer in August 2025. Cristiana Guiducci, Ph.D., joined as chief scientific officer in August 2024. In March 2024 the company appeared on BioSpace lists of promising new biopharma companies.

Risks & controversies

No controversies are reported in the sources. Sources contain inconsistencies that affect confidence in secondary data: founding year is given as 2021 internally versus 2022 in one third-party profile; headquarters is listed as both San Francisco and South San Francisco; one aggregator lists an employee range of 1001-5000 and an investor list (including HBM Partners, OrbiMed, Section 32, Vivo Capital) that is not corroborated by the company's own Series A announcement. As a preclinical-stage biotech, the company has no disclosed revenue and its programs remain unproven.
