Wyndly logo

Wyndly

Life's better without allergies

Wyndly (https://www.wyndly.com) fixes allergies by training patients' bodies to ignore their allergy triggers. Frustrated allergy suffers come to us when they no longer want to deal with pills and sprays. We diagnose the patient’s unique allergy profile and create a personalized treatment plan to give the patient lifelong allergy relief. Specifically, Wyndly is increasing access to sublingual immunotherapy (SLIT) for allergy care. For our patients, we're combining the convenience of telehealth and direct-to-consumer care with an exceptional patient experience that never loses the context of care. Wyndly represents an opportunity to change allergy care forever. With 60 million Americans suffering from allergies today, and with this number doubling over the coming years, there's simply an incredible need for the convenient care Wyndly provides. You can read more about us in [Techcrunch](https://techcrunch.com/2021/02/12/wyndly-aims-to-bring-allergy-drops-to-the-masses/). The Wyndly Model At Wyndly, we believe that better connections lead to better care, and we’re committed to making both happen at every step of the patient journey. Our allergy practice allows our patients to work with expert providers to develop personalized treatment plans for long-term allergy relief using clinically proven therapies. From a patient’s initial consultation to their final treatment delivery, we want the Wyndly experience to be a breath of fresh air for allergy sufferers – truly effective allergy relief, simply and efficiently delivered. Once we've conquered allergies, we're transforming the care model for every chronic condition. While transactional care for purchasing pills has flourished in telehealth, no one has gone after chronic care. Patients with chronic conditions are shuffled between providers, insurance, and more -- and they never feel heard. These patients deserve better, and we're going to give it to them. Wyndly is starting with allergies, but we'll expand into asthma, sleep apnea, and other conditions in the near future. Our values **Compassion**: We approach all our patients and partners with an open mind and a genuine desire to be of service. **Focus**: We do a few things very well, and are always clear about our boundaries and direction of travel. **Courage**: We embrace ambiguity and discomfort because we know that’s how we grow. **Progress**: We make something better every single day. *It boils down to empathy and forward momentum in everything we do.* The team Wyndly is proudly backed by Y Combinator and a leading group of angel investors and VCs. The founders are Dr. Manan Shah (Chief Medical Officer), an ear-nose-and-throat surgeon who’s a leading practitioner of telehealth in his specialty, and his cousin Aakash Shah (CEO), who led growth engineering at SparkGift (acquired by Stockpile in 2016) and Parse.ly (acquired by Automattic in 2021).

XGenomes logo

XGenomes

XGenomes is building the sequencing technology of the future.

At XGenomes, we are building a technology comprising novel biochemistry, hardware and algorithms for sequencing DNA. Our product will be streamlined: there is zero library preparation; we sequence directly on unadulterated single molecules of DNA; DNA extraction will be integrated with sequencing; there is no bioinformatics bottleneck. The sequence we produce will be of unprecedented accuracy due to several layers of in-built redundancy including the sequencing both strands of the double-helix concurrently. The sequence we produce will be complete, encompassing: structural as well as single nucleotide variants; long-range haplotype phase; the repetitive "dark matter" of the genome. The cost of goods (consumables) of sequencing will be <$10, which will allow us to price our product at a level that will help grow the market while still achieving >90% margin. We will start by offering access as a service to high value customers, which be followed by a razor and blade model of selling instruments and consumables.

YourChoice Therapeutics

YourChoice therapeutics is revolutionizing the contraceptive market…

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.

Zealth logo

Zealth

Software for remote monitoring of cancer patients

Zealth is building remote monitoring software to help hospitals provide automated continuous round-the-clock support to their cancer patients post-discharge. Hospitals are overburdened with no resources to provide care to their chronic patients once they leave the hospital. For instance, in India, there are only 2200 oncologists for 1.38 billion people. Patients travel 100 miles waiting for hours to get few minutes with the doctors. They have no easy means to manage all the toxicities and symptoms they get once they are back home. This leads to 6X lower patient retention, 4X high emergency readmissions, and poor patient outcomes. Zealth bridges this gap through its digital health intervention platform.

Zeit Medical logo

Zeit Medical

Immediate stroke detection at home

Zeit Medical leverages the power of AI and wearable sensors to deliver peace of mind for those affected by stroke. Zeit’s smart headband immediately detects the onset of stroke and notifies 911. Each year more than 90% of the one million strokes in the US go untreated, resulting in life-long disability and exploding medical costs north of $100b. The lack of timely treatment is the result of delays in alerting the emergency services. More than 10 million Americans with an elevated stroke risk live with constant fear that a stroke may go unnoticed for hours, while they are asleep or alone. The company was founded by Orestis Vardoulis PhD a biomedical & mechanical engineer and expert in digital health (EPFL/Stanford) and Urs Naber MD a critical care physician (Dartmouth/Stanford). They have both seen the devastating effects of stroke in their families and came up with the idea of addressing this unmet clinical need during their Stanford Biodesign Innovation Fellowship.

Zenflow

Medical device that provides a more effective, less invasive…

Forty million men in the US and over 500 million worldwide suffer from urinary obstruction related to benign prostatic hyperplasia (BPH). The majority of men will experience symptoms of this disease at some point in life. BPH, also known as prostate enlargement, leads to urinary straining, frequency, urgency, and sleep disruption. Despite the high prevalence and significant quality of life burden of BPH, established treatments are limited to drugs, which have limited effectiveness, and surgery, which carries a high risk of sexual side effects. The Zenflow Spring is a small implant delivered in the urologist's office in a simple procedure that provides quick and long-lasting symptom relief.

dNovo logo

dNovo

The cure for hair loss.

At dNovo, we are curing hair loss by creating new hair, de novo. We are doing this with cellular reprogramming technology that we pioneered at Stanford and Harvard. With this technology, we can take any patient derived cell, whether it be blood, skin or fat and reprogram (convert) them into medically relevant cell types. Our first objective is to cure hair loss by using our reprogramming technology to make new hair (patent pending). This is different from everything currently available on the market because the hair loss industry is focused on maintaining the hair that you already have, but no one is trying to produce NEW hair, de novo. After hair, we envision using our cellular reprogramming technique to make any cell, any tissue or any organ on demand to replace what is lost as we age.
