Ayodeji Ijishakin is a British-Nigerian entrepreneur and machine learning researcher who is the co-founder and chief operating officer (COO) of Mecha Health, an applied artificial intelligence company that builds foundation models to automate x-ray analysis for radiologists. The company participated in Y Combinator's Winter 2025 batch and is based in San Francisco, California.[1]
Early life and education
Ijishakin is of British-Nigerian heritage. He completed a PhD in Machine Learning and Medical Imaging at University College London (UCL), where he met his future co-founders during their doctoral studies. His academic research focused on applying machine learning techniques to medical imaging problems. During his time at UCL, he published peer-reviewed research at leading artificial intelligence conferences including NeurIPS, ICLR, and ICML.[2]
Career
Ijishakin co-founded Mecha Health in 2024 alongside colleagues he met during his doctorate at UCL. The company develops proprietary vision-language foundation models that process medical images—beginning with x-rays—and produce draft radiology reports containing structured findings and impressions.[2] The company's technical pipeline ingests medical images in standard healthcare formats including DICOM, HL7, and FHIR, and outputs structured clinical reports that radiologists can review and approve.
According to the company, its first model was built in less than two months and outperformed models from Microsoft, Google, and OpenAI on clinical accuracy metrics, while being approximately 100 times smaller in scale and trained on a quarter of the data.[1] Mecha Health has described a goal of expanding these capabilities with new vision-language foundation model features intended to further automate the radiology workflow.[3]
The company's stated goal is to address radiologist shortages and burnout by increasing workflow efficiency. Mecha Health claims its technology can enable radiologists to move from reading one scan per hour to one scan every five minutes. The company operates on a per-scan pricing model and estimates that x-ray report generation represents a market opportunity exceeding $40 billion.[1] Mecha Health has partnered with what it describes as the largest privately owned radiology practice in the United States and a multinational tele-radiology company to provide customized foundation models for their radiologists.[2]
The company raised $4.1 million in seed funding in a round led by Valia Ventures, with participation from Y Combinator, Rebel Fund, Reach Capital, and Phosphor Capital.[4][5]
As COO, Ijishakin focuses on the operational and business aspects of the company, working alongside his co-founders on strategy, partnerships, and growth, while the company's technical work draws on the machine learning and medical imaging research expertise the founding team developed during their doctoral studies at UCL.
