  • Inner Logic

    Participated · Seed · Jul 2026

    Inner Logic develops a simulation and data platform that allows device manufacturers to design, test, and validate procedural devices across thousands of virtual patients grounded in real clinical and procedural data. The company’s infrastructure aims to shift exploratory device development from physical prototypes and cadaver labs into in silico testing to accelerate iteration and broaden patient coverage. Founders include CEO Tito Porras, MD; CTO Mathias Unberath, PhD; and Chief Robotics Officer Axel Krieger, PhD, who collectively have authored over 400 peer-reviewed publications and are named inventors on more than 40 patents. Inner Logic has demonstrated its technology by training AI in simulation for orthopedic trauma and deploying it successfully on real hardware and patient anatomy, and by completing key steps of an autonomous gallbladder removal in a live animal model. The company is positioning its platform to support the development and validation of intelligent and autonomous procedural systems as they move toward clinical deployment. The announced financial position includes an $11.5 million seed round to advance product development and scaling.

  • Delfi Diagnostics

    Participated · Series B · Jul 2022

    DELFI Diagnostics is a Palo Alto–based developer of blood-based cancer detection tests that use fragmentomics and advanced machine-learning methods applied to whole-genome sequencing data. The platform analyzes patterns of cell-free DNA fragments to detect chaotic signatures left by cancer cells. DELFI has commercialized FirstLook Lung, a blood test that evaluates DNA fragment patterns to indicate the presence of lung cancer. In an independent validation, FirstLook Lung demonstrated 80% sensitivity in a screening population, including early-stage detection, and a 99.8% negative predictive value. The company received an equity investment from the Merck Global Health Innovation Fund and intends to use the funds to accelerate development and commercialization of its cancer detection solutions. Led by CEO Susan Tousi, DELFI positions its fragmentomics and AI technologies as a potential high-precision, population-scale approach to early cancer detection at a disruptive price. Delfi Diagnostics has built a platform that analyzes cell-free DNA fragments across the entire genome using a proprietary, scalable whole-genome fragmentation approach. The platform is designed to enable a single, low-cost, and straightforward lab process for multiple liquid-biopsy tests and leverages machine learning to deliver high-performing results. Led by CEO and founder Victor Velculescu, the company is validating its technology for early detection of lung and other cancers in a 15,000-person prospective trial called CASCADE-LUNG. Delfi is working with multiple research institutions to develop additional applications including screening for other cancer types, multi-cancer early detection, and treatment monitoring.
