Osmind
Platform for breakthrough mental health research and treatment
Osmind is the premier platform for clinicians and researchers advancing new life-saving mental health treatments. Today, mental health disorders are one of the leading causes of death worldwide, especially among young adults, and are tied to shortening lifespans. While there have been developments in new psychiatric medications since the first FDA approval in 1954, today there is a growing movement among clinicians, patients, and researchers who are recognizing the need to accelerate new science. The Osmind treatment platform is the first and only solution that solves specific challenges faced by neuropsychiatric clinics, spanning general psychiatry and interventional psychiatry (transcranial magnetic stimulation, ketamine, SPRAVATO®, psychedelic medicine, electroconvulsive therapy). The core electronic health record (EHR) technology is precisely developed for interventional treatment workflows and designed to support a strong therapeutic alliance, including journaling tools and assistance with health plan reimbursement, which is a significant access hurdle for millions of patients. Research from our platform is already helping to set new standards for mental health interventions. For example, in the largest published real-world analysis of ketamine infusion therapy for depression, we teamed up with Stanford University School of Medicine to share findings in the Journal of Affective Disorders (March 2022). We have multiple ongoing research studies leveraging our proprietary real-world data, including an even larger ketamine analysis leveraging machine learning to predict treatment outcomes. Osmind is a San Francisco–based public benefit corporation led by scientists, technologists, and psychiatrists. We are backed by top investors including DFJ Growth, General Catalyst, Future Ventures, Tiger Global, and Y Combinator.
Osseus
The secure research brain for accelerating R&D
Osseus is the secure research brain for R&D teams. Today, research knowledge is fragmented across specialist tools, decisions, conversations, and people's heads. Osseus crafts this into a permissioned memory that grows with every experiment, decision, failure, and lesson learned. Rather than only retrieving the current state of connected tools, Osseus preserves how work evolved: what was tried, what failed, why decisions were made, and who holds the relevant context. Each person gets a personal AI agent that uses this growing history to proactively surface relevant evidence, help prevent duplicated work and repeated mistakes, and identify the exact expert who can unblock the next decision. By preserving both technical history and the organizational know-how behind team processes and decision making, Osseus helps R&D teams move faster before time and money are wasted.
Ossus
Intelligence for cultural institutions
We build intelligence for cultural institutions. Our first commercial product is for the literature industry with a focus on school and public libraries. It is a AI-native OS for libraries, that helps librarians save time on tedious tasks and lets them focus on their patrons.
Outerport
EDA for Industrial Control Systems
Building out new LNG plants, HVAC systems, or semiconductor processes rely on hundreds of iterations of feasibility testing (through simulation or real-world lab tests) where different designs (combinations of equipment) and parameters are validated. The parameters are often locked in PDFs (datasheets, wiring diagrams, PFDs/P&IDs) which take thousands of hours to convert into CSVs / JSONs, and the simulators don't have an easy API to work with. Outerport bridges the gap by finding documents from PLMs, extracting structured data from drawings, building a knowledge graph over them, and building autonomous AI agents that can fully automate this R&D process by running simulations and performing design checks.
outloud.ai
Building Gong.io for offline retail.
We record conversations that customers have when they are placing orders in drive-thru restaurants, automatically analyze them, and help operators to upsell better or alert them when they are out of stock.
Output Biosciences
The foundation for the next era of biology
Output is a fully integrated AI lab building Artificial General Biological Intelligence, from the molecular level up to whole systems. The discovery of new biology and the design of therapeutic moonshots become routine.
Outrove
Synthetic populations for decisions
Surveys ask people what they think they’ll do. Focus groups ask a handful of people to explain behavior they often don’t understand themselves. Outrove simulates entire populations instead. We create AI agents that model how real audiences behave, letting companies, governments, and investors test decisions in minutes: what product to launch, what price to set, what campaign to run, what policy will work, or how a market will move. The output is not another dashboard. It’s a prediction of what will happen, which segments will drive it, and what decision is most likely to win.
Outschool
A live online learning platform that empowers kids ages 3–18.
Outschool is an innovative education platform that offers a variety of engaging, small-group classes online. Unlike traditional classes, Outschool classes give kids the unique opportunity to explore their interests in-depth via interactive, live video by experienced, independent educators. When Outschool was founded in 2015, homeschoolers were the first to discover our classes, but it wasn’t long before kids in conventional schools began supplementing their education with fun and unique, interest-based classes. During the COVID-19 pandemic, Outschool became vital to families who wanted to keep kids learning, social, and pursuing their passions. Today, Outschool offers more than 140,000 live online classes to more than 1,000,000 learners in 183 countries worldwide.
Outset
AI-powered user interviews
Outset offers AI-powered user interviews to conduct qualitative research. Traditional surveys are fast but lack depth while live interviews produce high quality data but are slow and expensive. Outset uses LLMs to lead interviews and synthesize results so researchers get high quality data 100 times faster.
