Alzheimer’s is tough. And while there is no cure, getting help should be 100x easier than it is today. We’ve raised over $6 million to solve that problem. When someone is going through the disease, there are many different things they need help with (i.e. memory issues, depression, fall risk, safety in the home, etc). The primary person responsible for that care is one of the patient’s loved ones – usually a child or a spouse. That’s a really difficult thing for the loved one to do. It’s stressful, time consuming, and difficult. If we can make their lives easier, we can not only improve their experience but also create better patient outcomes. We’re building the world’s first one-stop-shop, d2c care platform for Alzheimer’s, starting by optimizing the care monitoring, management, and intervention processes.

Digital health holds a lot of potential but is ignoring a growing problem: diagnostic testing. Without this data, providers and organizations will be limited in the services they can provide patients at home. Scout has developed a platform - Hub, test kits, and app - that delivers health testing at home with 10x lower development cost and 3x lower per-test price. Our patented tech also meets performance requirements for medical diagnoses and integrates with the current healthcare tech stack. Scout’s technology is poised to disrupt the outdated $33Bn diagnostic market by democratizing testing while dramatically improving the patient experience. Scout has received $16M in non-dilutive funding from the NIH and other organizations to fully de-risk our platform, and our pipeline includes a diverse test menu for primary care (e.g. respiratory and sexual health), wellness (e.g. gut health), and chronic conditions (e.g. certain cancers). We have already received FDA authorization for our platform in clinical settings and are planning to launch our flagship Scout Hub in Q1 2024.

Over 80% of maternal mortalities were preventable with earlier intervention. Currently, doctors miss >50% of moms who have life-threatening complications and wait until labor to start doing manual risk assessments, at which point it's too late. Elythea's proprietary ML models catch life-threatening obstetric complications (like postpartum hemorrhage, preeclampsia/eclampsia, emergency c-section, preterm labor, and more) as soon as the first visit. We automatically analyze relevant demographic and clinical risk factors, flag high-risk patients, and provide evidence-based interventions, giving doctors months in advance to intervene and prevent complications from ever happening. Our global clinical studies have shown that we can catch 2-3x more complications than clinical judgment 10x sooner.

Auricle is a medical device company building a breakthrough neurostimulation implant to restore hearing in millions of patients who no longer benefit from hearing aids, get less than 60% on a word recognition test, but aren't prepared to make the jump to a cochlear implant. Our approach preserves remaining natural hearing through a reversible and less invasive surgery, addressing the key concerns that hold most patients back from getting a cochlear implant (currently the only treatment option for these patients). The company spun out of Stanford Biodesign having completed two acute human clinical studies demonstrating the approach will work. The team is now focused on developing their full implant system for their first clinical trial. Auricle addresses a currently unserved profile of hearing loss that affects a growing population of 3.5 million patients in the US and represents an immediately accessible $1.2B market opportunity with existing reimbursement.

Our Mission: "One human, One Doctor" because access to a doctor at any given time is a basic human right. Customer: Healthcare Organizations Product: All-in-one solution to save doctors time. Problem: Doctors spend 50% of their time on things other than patient care, and the other 50% is inefficient. Solution: All-in-one solution for doctors that saves time from pre, post, and during-visit. Opportunity: Over 110 million patient care visits occur in the US annually, and the current average cost per visit is $300. When future visits are done by an ASI (Artificial Super Intelligence) doctor at a 10x cheaper cost ($29 per visit), it’s $3.9B in revenue in the US only and $25B+ globally.

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.

YourChoice Therapeutics is revolutionizing the global contraceptive market. Our vision is to develop non-hormonal contraceptives to provide both women and men with birth control options that lack the associated risks of hormone-based options but are equally effective. Traditionally, it has been the women’s financial and health burden to have a contraceptive in place. Our first goal is therefore to bring a novel non-hormonal, on-demand and low cost female contraceptive to the market that will substantially improve their quality of life and well-being. Our second goal is to develop the first ever non-surgical and highly effective non-hormonal contraceptive for men. Currently, male contraception is limited to two main options – vasectomy or condoms. Having such options available to both women and men will globally allow for much better family planning, reduce the number of unwanted pregnancies including abortions and therefore reduce costs and ensure contraceptive health and well-being.

We’re on a mission to leverage AI and voice technology to solve inefficiencies and revenue leakage in our healthcare system. With the rise of EHRs, the manual documentation burden on doctors has never been higher, leading to burnout and fatigue and high attrition rates. Assigning the correct diagnosis and billing codes is crucial for proper reimbursement and patient care, but medical coding is becoming more and more complex each year with growing numbers of codes (over 145,000 now), and doctors are unsupported by current technology to keep up with its ever increasing requirements. $125 billion is left on the table each year by healthcare organizations due to improper documentation and coding. Knowtex creates visit notes with up-to-date and accurate reimbursement codes from doctor-patient conversations, allowing the doctor to focus on patient care and preventing revenue leakage for hospital systems through standardized, transparent, and accurate documentation.
