Top Tech Startups in United States in 2026

Optical microscopy continues to be the tool of choice for the zebrafish research community. However, capturing clear images of relevant biological phenomena still remains a challenging task. It is not possible to simultaneously image a wide area and maintain high resolution using current microscope technology. At Ramona Optics, we are developing a new patent-pending gigapixel microscope that can capture cellular-scale resolution (5-10 µm) in 3D over an entire 100 mm diameter Petri dish. This unprecedented resolution/field-of-view combination opens up a new horizon for high-throughput, non-invasive imaging of the motion, behavior and activity of unconstrained organisms. Our microscope acquires high-resolution gigapixel images (with 1 billion pixels) in a single snapshot. This new capability frees researchers from the historical limitations imposed by classical optics, which typically can only capture megapixel-scale images from a small sample area.

We're a team of machine learning and product engineers training task-specific generative models for psychology.

If that sounds like home, we'd love to hear from you. The Team Daniel started coding at age 8 and started training models in high school. At 16, he dropped out of high school and moved to London to pursue his study and research. He graduated university top of his class at 19 and was awarded ‘distinguished’ by Imperial for his post-grad research in AI for mental health. As an ML Engineer, he led Instabase’s pivot into GenAI. He raised $6M pre-team at age 22 to develop the tools for training task-specific generative models that now power our machine learning research. Neil dropped out of medical school to co-found Casper, the sleep company, which he helped grow to $500M+ in revenue and IPO’d in 2020. Improving wellbeing through sleep led him to mental health, where he joined the board of [PsychHub](psychhub.com). He’s invested in 200+ companies like Ro, Affirm, Relativity, Archer, Figure, and Together.AI. Our team has expertise in model training, product engineering, and psychology. Our engineers includes team leaders who have joined us as individual contributors, two former CTOs, and collective experience from across Big Tech.
