  • AesculaTech
    AesculaTech (w2018)Active • 6 employees • Los Angeles, CA, USA
    AesculaTech believes in building better lives through smart chemistry. We design custom smart materials for a range of biomedical, commercial, and industrial applications. Our platform technology, AesculaGel offers adaptive response to a wide range of stimuli and can be tailor-made for biocompatibility, material strength, and a range of other attributes. Founded by one of MIT's 35 under 35 Innovators, AesculaTech is the shared vision of scientists, engineers, and medical experts. Our cornerstone product, Humidifeye, is an ophthalmic platform to treat dry eye disease. Dry eye affects more than 25 million Americans and the global treatment market is projected higher than $6 Billion within the next decade. Our thermally responsive, form-fitting materials are suitable for sustained yet reversible occlusion across a range of treatment times. In contrast to existing technologies, our product will not extrude, or cause discomfort as it adapts to patients. Though Humidifeye is not yet FDA approved, expect to hear about it soon! In coordination with partners across several sectors, we have a variety of groundbreaking technologies in the works that live up to our vision. This work has already been recognized. AesculaTech was named a Rosenman Innovator, received a National Science Foundation I-Corps grant, was a finalist in the 2019 Octane High Tech Awards, and is a graduate of both the Y Combinator and TMCx accelerator programs. In short, Y-Combinator was only the beginning.
  • Oncobox (s2017)Active • 11 employees • Walnut, CA, USA
    Oncobox believes that many late-stage cancer patients are dying prematurely because doctors lack a data-driven tool to help them decide which drugs currently on the market would most effectively fight individual patients’ specific cancers. That’s where Oncobox comes in. Oncobox is low-cost personalized genetic profiling to help doctors decide which drug to use. In a recent study conducted by leading cancer researchers in Europe and Asia on 900 patients with various late-stage cancers, Oncobox increased the effectiveness of targeted therapies from 25% to 64%. How does Oncobox work? Over 150 targeted cancer drugs are currently on the market. But deciding which of these drugs to give to late-stage cancer patients is not a simple task. Cancer doctors are in a race against the clock. They don’t always know which medication will be most effective for their patients. Because these drugs are expensive and typically have significant side effects, they can’t just try them all. Because of these barriers, targeted cancer therapies are effective only 25% of the time, and 70% of patients with late-stage cancers die due to the toxic side effects of ineffective drugs. Oncobox Dx analyses tumor DNA, RNA, and molecular pathways using algorithms to distinguish which molecular targets are the most crucial for individual cases. Doctors receive a clinically actionable report that shows them which drugs are likely to be most effective on the patient. We actively seek partners from pharma, hospitals/clinicians, payers, and genomic centers. Feel free to contact us at Our team and the scientific advisory board consisting of leading scientists and researchers from UCLA, Stanford, Johns Hopkins University, Boston University, Tufts University, and Rutgers University.
  • Makani Science
    Makani Science (s2021)Active • 2 employees • Irvine, CA, USA
    Makani Science is a medical device company based in Irvine, California. We have created the world's first wireless patch that can accurately and continuously monitor breathing. The company is co-founded by Dr. Michelle Khine and Dr. Michael Chu, two experts in the wearable monitoring space from the University of California, Irvine. The Makani Science system will collect unique breathing waveforms from patients in everyday environments to create the first large database of respiratory patterns associated with different diseases. Data will be collected through systems sold to our initial beachhead market, where we will help improve monitoring safety in patients being sedated for medical procedures. Our long-term goal is to combine machine learning with this database to identify and predict respiratory complications for different patient populations. We have a highly experienced team and will be FDA cleared in our beachhead market within a year.

  • Forcyte Biotechnologies
    Forcyte Biotechnologies (w2021)Active • 5 employees • Los Angeles, CA, USA
    In a nutshell: many diseases are caused by how much your cells squeeze (asthma, fibrosis, others). We discover drugs that control how much cells squeeze, with ease, to treat disease. We use patented bioMEMS technology to turn cell strength (cells' ability to pull/ squeeze) into a quantifiable metric in drug discovery, to help find better drugs for mechanical diseases. We screen 100,000s of drugs against numerous contractile human cell types to comprehensively map human mechanobiology (the "contractome") and identify promising drug development starting points to deliver novel medicines to treat mechanically-driven diseases including asthma, hypertension, preterm labor, fibrosis, and others.

  • Serif Health
    Serif Health (w2022)Active • 6 employees • Los Angeles, CA, USA
    At Serif Health, we are taking the complexity out of the cost of healthcare. Our mission is to make healthcare pricing and contracting more transparent, easier to understand, fairer, and ultimately more affordable for all. New price transparency regulations have made a wealth of healthcare pricing and reimbursement data publicly available for the first time, but it is still extremely hard to ingest, organize, and actually use this data to understand the cost of care. That’s where we come in. Serif Health is building healthcare price intelligence data products and APIs to power the future of more transparent healthcare. We are an early-stage, venture-backed startup with a small, collaborative team of healthcare experts, engineers, and designers. We are excited to add new team members motivated by our mission, passionate about making a difference in healthcare, and looking forward to learning and growing from the challenges we will face along the way!
  • Parallel Bio
    Parallel Bio (s2021)Active • 9 employees • Cambridge, MA, USA
    Parallel Bio created a human 'immune system in a dish' to discover drugs and immunotherapies more likely to work in patients. Our platform has all of the same elements as a human immune system, meaning you can test drugs and vaccines as if you were testing them in actual patients from the start. The biggest reason why 95% of new drugs fail is that they were tested in mice - but with our human platform, pharma companies will know which drugs will successfully treat patients, speeding up the process and reducing the cost. To date our platform has successfully been used to test 12 drugs, and vaccines against 8 different diseases. The company is founded by Robert DiFazio, a former Stanford R&D director with a PhD in immunology, and Juliana Hilliard, a former System1 Biosciences R&D lead with an MSc in bioengineering, both of whom have led drug discovery programs for years.
  • Almond
    Almond (s2022)Active • 8 employees • Los Angeles, CA, USA
    Almond is like One Medical but for women’s health: we make it easy to get great ObGyn care fast, both at our in-person offices and over telehealth. The problem with traditional ObGyn practices is that physician time is misused, so patients get slow care. We're rebuilding back-office tech that saves physicians time, and we're hiring a wider range of care providers roles, which let us deliver better outcomes to patients and reduce the amount of time it takes to get their issue resolved.
