May 2025Series D-$365M$1.6BPathos AI is a biotechnology company specializing in AI-driven drug discovery and development for oncology, leveraging multimodal data including real-world oncology data, patient-derived functional genomics, clinical, imaging, and molecular datasets to optimize therapeutics, accelerate biomarker-driven development, and improve patient outcomes. Founded around 2020-2022 by executives from Tempus, including chairman Eric Lefkofsky, the New York/Chicago-based firm recently appointed Iker Huerga as CEO and has advanced a clinical-stage pipeline, including lead drug pocenbrodib in phase 1b/2a trials (licensed from Novo Nordisk), P-500 (PRMT5 inhibitor acquired from Prelude Therapeutics, phase 1 completed), and collaborations like a multi-year deal with AstraZeneca and Tempus announced in April 2025 for a large-scale multimodal deep learning model, with Tempus receiving $200M in fees. The company closed a Series D funding round around mid-May 2025 (sources cite April 17 or May 15, 2025), raising between $283M and $365M, which propelled its post-money valuation to $1.6 billion, marking unicorn status in roughly three years. Lead investors varied across reports: New Enterprise Associates and Revolution in some accounts, Insight Partners with D1 Capital and Coatue in others, building on prior backers like Builders VC from a $62M Series C in 2024. Total funding raised post-round reached $345M to $467M per different trackers. One outlier source reported a $2.8B valuation, but consensus across authoritative outlets like Axios, Pharmaceutical Technology, and Pharmaphorum confirms $1.6B post-money. Proceeds fund expansion of the AI foundation model for oncology, clinical asset advancement, trial design, biomarker discovery, engineering scale-up, market reach, and therapeutic innovation. The round underscores investor confidence in AI platforms for biotech amid strong sector interest, positioning Pathos against competitors in precision medicine and drug development.
Oct 2024Series CNew Enterprise Associates (lead); Lightbank; Revolution Growth; Builders VC$62M$600MPathos AI is a Chicago-based clinical-stage biotechnology company that re-engineers drug development using artificial intelligence, focusing on precision oncology therapeutics. The company leverages AI to analyze multimodal real-world data, including patient outcomes, DNA and RNA sequencing, to improve patient selection, clinical trial design, and resurrect shelved compounds. Founded by Tempus executives including Eric Lefkofsky, Pathos applies causal AI frameworks to identify drugs with safe Phase I profiles likely to succeed in targeted populations. On October 29, 2024, Pathos closed an oversubscribed $62 million Series C funding round led by New Enterprise Associates, with participation from Revolution Growth, Lightbank, and Builders VC. This round achieved a $600 million post-money valuation and brought the three-year-old company's total funding to $102 million. The capital will expand its team of scientists and engineers, accelerate its AI-powered PathOS platform, and advance clinical-stage assets like P-300 and P-500, acquired in the last 12 months from Prelude Therapeutics, Rain Oncology, and others, with trials planned for 2025. Pathos differentiates from traditional AI drug discovery by targeting existing Phase I cancer drugs for optimization rather than de novo design. It partners with pharmaceutical companies to develop shelved programs and has secured three such assets to date. The funding underscores investor interest in AI-life sciences intersections amid Chicago's growing biotech scene, despite sector challenges like lab space vacancies.
