  • Guardian Bio
    Guardian Bio
    Y Combinator LogoS2022
    Active • 2 employees • Boston, MA, USA
    Your immune system is your body’s best weapon and defense against cancer. It is only when it is overcome that cancer develops into full blown disease. Dendritic cells sit at the helm of the immune system, directing and dictating immune responses. Data has shown dendritic cells are often dysfunctional in cancer patients, and that this dysfunction is a bottleneck for other therapies. Guardian Bio’s approach is focused on creating a dendritic cell-based product which drives anti-tumor activity through activating the killers of the immune system AND training them against multiple cancer targets. We take stem cells from cancer patients, turn them into specific therapeutic dendritic cells specially trained against that patient’s tumor, and re-introduce them back into the body. Our therapeutic dendritic cells revitalize the killers of the immune system and give them the kickstart they need to fight - and win - against cancer.

  • Reviving Mind
    Reviving Mind
    Y Combinator LogoW2022
    Active • 3 employees • Boston, MA, USA
    Navigating chronic illness is an isolating and lonely process which ultimately reduces medical adherence and adversely impacts outcomes. There are over 100 deadly chronic conditions as 1 out of 2 Americans is currently living with at least 1 chronic condition. The US healthcare system has over $1 trillion dollars in direct costs. Medical adherence rates for therapeutic programs and medicine are only 50% because patients feel lonely, isolated, and unsupported in their chronic illness journey. Reviving Mind is an in-network telehealth provider that improves clinical outcomes and program adherence for the senior medicare and medicare-advantage population that is plagued with loneliness and chronic illness. This is done through a novel and proprietary clinical program and technology platform that integrates virtual, private, curated, and professionally led groups that scale up to 8-patients with individualized and goal oriented lifestyle medicine coaching that is automated but managed by a licensed provider. Scaling rapidly across the United States.

  • Parallel Bio
    Parallel Bio
    Y Combinator LogoS2021
    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.

    DNA has emerged as a compelling data storage medium due to its density, longevity, and eternal relevance compared to current memory technologies. However, the high price of synthesizing DNA remains a major bottleneck for adoption of this promising storage solution. We are pioneering new approaches to synthesizing DNA for data storage with enzymes and custom digital codecs. We are building an interdisciplinary team to build the world's most scalable information infrastructure in DNA. We seek technical experts in enzyme engineering, chemistry, hardware engineering, and information theory. We also seek business development to identify emerging markets for early use cases of our technology.

    Y Combinator LogoW2019
    Active • 6 employees • Cambridge, MA, USA
    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.

    Y Combinator LogoW2017
    Active • 22 employees • Boston, MA, USA
    Technology finds information and delivers physical products to us almost instantly. mRNA does the same for biology. At HelixNano, we see a world where treatments are cheap, progress is decentralized, and you can modify biology at the push of a button. By focusing on mRNA improvements from first principles, we’re getting there faster than we thought. Experiments that used to take months or years can be done in weeks and cost thousands instead of millions. The rate limiting step for our progress is now scientific curiosity. Rigid hierarchies and top-down decisions will miss the magic. Some of our most powerful technologies started out as side projects of junior team members. At HelixNano, every individual scientist can have a massive impact on the company's direction. And the more diverse our team, the faster we’ll find the really cool ideas. We've started rolling out some of our new tech — moving a COVID-19 vaccine candidate for the immunocompromised towards the clinic, and testing an intervention with massive environmental impact. But we’re scientists at heart, and team focus is solidly on the horizon.
