Nectome is a neuroscience startup that aims to preserve the brain and keep all its memories intact. The company is building the next generation of tools to preserve the connectome. The connectome is all the connections called synapses between neurons in the brain. Researchers from the company is now learning to manipulate individual memories, building advanced brain prosthetics, and reverse-engineering the brain.

Our lead candidate is a multifaceted attack antibody for ovarian cancer. Our approach enables targeting primary cancer cells directly, alongside enabling the immune system's natural anti-cancer function, all with one therapeutic antibody.

Our vision is to provide regenerative medicine treatments that free patients from chronic liver disease and help usher in an era where diseased and damaged tissues can be repaired.

Delivery of TERT mRNA extends telomeres sufficiently in a few days to reverse over a decade of telomere shortening during normal aging. We are advancing TERT mRNA-based therapies to the clinic.

Intatct is developing an advanced materials platform to improve the way drugs are delivered and absorbed in the digestive tract. Our vision is to improve the treatment of a wide range of gastrointestinal disorders that are currently underserved.

Endpoint Health is on a mission to address urgent needs in immune-driven critical and chronic illnesses by delivering therapies that are personalized to each patient’s biology. We built Endpoint Health from the ground up to develop and commercialize therapeutics and therapy-guiding tests, to ensure that every patient receives personalized treatment that will dramatically improve their outcomes. Our vision is a world in which all patients have effective, personalized treatment, because therapies are targeted to the right patient at the right time.

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.

GEn1E Lifesciences is a Clinical-stage, multi-target company with a unique AI platform. We develop novel, next-generation, immunomodulatory therapies for rare & inflammatory diseases with no effective treatments. Our team is supercharging the drug development cycle by applying AI to multiple-mechanism-of-action protein targets and their natural platform capabilities—creating novel therapeutics at an unprecedented pace. Our AI platform has enabled us to develop a purpose-built therapy for ARDS to reduce its $20 billion cost on society (just in the USA). GEn1E has built a rich pipeline of 21+ novel and selective immunomodulators and has plans to accelerate 2 additional devastating diseases (beyond their lead indication) to IND in the next 12 months. Our AI platform enables tremendous pace and capital efficiency as demonstrated by our progress in ~2 years with seed capital—a stark contrast to the typical spend of $100M+ and 7+ years exhibited in the pharmaceuticals / biotech industry. With ~90% of rare diseases having no therapeutic treatment at all, GEn1E is taking a giant swing that will hopefully bring life-saving therapies to the lives of patients in need. The team at GEn1E has decades of experience in drug development and machine learning. We graduated from YCombinator and Stanford-StartX in late 2019. We are based in Palo Alto, CA.

Asher Bio is a biotechnology company developing precisely targeted immunotherapies for cancer and other diseases. Our cis-targeting platform aims to enable selective activation of specific immune cell types, addressing the inherent limitations of otherwise pleiotropic immunotherapies that act on multiple cell types. Our approach has the potential to precisely direct different immune mediators against a range of target immune cell-types and create best-in-class immunotherapies in cancer, autoimmune and infectious diseases. Asher Bio is backed by Third Rock Ventures and is located in South San Francisco.

Altay develops small molecule drugs to treat chronic liver diseases like liver fibrosis and liver cancer. Our co-founder Dr. Osman Ozes, led the first drug development program for Esbriet (Pirfenidone), resulting in the first FDA approved therapy for lung fibrosis. Esbriet is now a $1 billion/year drug and has already made over $6 billion in revenue. With a team that has over 70+ years of small molecule drug development experience, we intend to do the same with chronic liver diseases, which affects over 20 million Americans and represents a market size of over $30 billion. We know we are well positioned for success because we have shown excellent pre-clinical mouse data in several liver fibrosis models using our novel small molecule. We demonstrate a reduction in fibrosis with our drug, but more significantly, we show a reversal in fibrotic tissue back to normal tissue. With our current developmental strategy, we hope to have a clinic-ready compound by the end of 2021 and be in phase I clinical trials by mid of 2022.

We are developing a drug to increase metabolism and burn calories without exercise. Obesity and type 2 diabetes have reached epidemic proportions. There are 2.2B overweight people and 500M people with type 2 diabetes worldwide, and these numbers increase drastically every year. Existing drugs are not effective enough to reverse the trend. Our drug can solve this problem, because it addresses the root cause of metabolic disorders – the imbalance between caloric intake and expenditure. Our drug will target mitochondria – the powerhouse of the cell – to generate heat. This approach has been proven to fully reverse obesity and type 2 diabetes in animals. However, therapeutic application for humans was impossible, because mitochondrial heat production could only be induced by highly artificial methods with side effects. This changed after our recent breakthrough discovery of the protein that mitochondria naturally use to generate heat. We have developed a unique high-throughput drug discovery platform to identify compounds that selectively activate this target protein, without side effects. For decades people have wanted a drug that burns calories like exercise does. We are realizing this dream at Equator Therapeutics.

Catena’s technology lets us attach any two proteins together using an enzyme and the native amino acids tyrosine and cysteine within target proteins. It is a true platform technology because it enables the joining of any two soluble proteins together with minimal engineering and without restrictions due to protein size or complexity. Our work has already been used to modify cancer specific antibodies, CRISPR proteins and even cell surfaces. Our ability to produce modular protein therapeutics in a fraction of the time allows for true library creation across the therapeutics spectrum from oncology, vaccines, inflammatory disease and beyond.

Keylika is an early stage biopharma startup developing metal-based drugs using a platform synthesis technology to treat unmet medical needs. We then administer these drugs using proven delivery technologies to effect the best clinical outcomes. Our first product is a small molecule iron drug (new molecular entity) delivered by a wearable skin patch to treat Iron Deficiency Anemia (IDA), with significantly higher safety, efficacy and tolerability over existing treatments. This is poised to be a best-in-class, potentially breakthrough therapy for treating iron deficiency without any GI side-effects (eg. nausea, constipation, diarrhoea, etc.) typically associated with oral iron supplements, and without the risks, costs and side-effects associated with IV iron infusions. When approved, Keylika’s proprietary transdermal iron will be the world's first prescription iron patch. Iron deficiency is a hugely understated problem affecting about 1.6 billion people worldwide and more than 30 million in the US alone, translating to a $17B US market.

Rosebud Biosciences accelerates drug development by screening drugs against organoids (micro-organs) that have the same gene mutations as the patients. We partner with therapeutics companies to screen their drugs, and we perform our own drug discovery for rare diseases that have no existing treatments. Our organoids are also fetal-like and enable discovery of novel drug targets for pediatric diseases. This technology was validated at Stanford, published in a prestigious journal, and has already led to the discovery of a drug target in a pediatric heart disease that could not have been found using traditional disease models.

Engage Bio is developing mRNA immunotherapies to defeat cancer. Our founders have deep experience in immunotherapy development, including four drugs in the clinic, and in building mRNA therapeutics platforms. Our approach is to provide cancer cells with instructions to make and gradually release our drugs within solid tumors. This local therapy allows us to eliminate tumors while sparing healthy distant tissues.

Our compounds disrupt the metabolic and inflammatory triggers in both cancer and quasi-cancerous cells in the tumor microenvironment. By impacting multiple cell types, we are enabling effective, lasting cancer treatments.

Eugit Therapeutics targets the issue of non-specific drugs that cause toxicity and clinical trial failures, affecting millions with tissue-specific inflammatory diseases. TAGHOME delivers drugs with precision to diseased tissues using T cell receptors, enhancing safety and improving efficacy. Our initial focus is on the 3.1 million U.S. individuals with Inflammatory Bowel Disease, aiming to initiate clinical trials within two years. Cofounded by George Church (Harvard) and funded by Y Combinator (S22).

Cell and gene therapy promises to one day cure any disease; Modulari-T’s Platform produces the tools to fulfill that promise. Modulari-T has designed a new family of synthetic genes that can reprogram cells to better sense their environment and modify their behavior accordingly. This can be used to engineer immune cells to efficiently recognize and kill cancer cells or to create stem cells able to regenerate any tissue. Modulari-T looks to expand its technology to reach every area of cell therapy and become the platform of reference for cell engineering.
