About Us

Novel therapeutics for serious diseases

Octant is scaling drug discovery to take on protein misfolding diseases

What we do

Octant is a therapeutics company building small molecule drugs that modulate cellular mechanisms.

We are pioneering a new type of small molecule drug discovery by using massive experimentation in human cells to unlock novel insights. The Navigator platform uses synthetic biology, high throughput chemistry, and AI/ML to understand and modulate how target proteins actually interact within cells (for example, signaling, transcription, trafficking), rather than just binding molecules to isolated proteins. We're hard at work on several promising programs in rare disease and oncology that are caused by protein misfolding.

Our Story

Setting a course for a new type of biotech

Despite the proliferation of genomic data, clinical data, and new biological technologies, many of the most pressing diseases in society are proving intractable with the current approaches. In many disease areas, scientific advancements have unlocked unimaginable levels of information, yet the challenge of successful and specific targeting remains. Some conditions present as one disease, when they’re actually a multitude of different diseases. In many diseases, we know a particular gene is involved in the disease, but have no idea which molecular mechanism will “fix” it.

Octant envisions a new approach to tackle these problems. We believe that recent advances in synthetic biology enable a new type of biotechnology. For example, we can today engineer cells to compute biological information at far greater accuracy and throughput than computational simulation. We set out on a journey to map the biochemical mechanisms that link genetics and chemical features to the disease. Because, ultimately, it’s the biochemical mechanisms that we drug.

Since then, we’ve been busy building a different type of company- of and by technologists- for patients.

We focus on complex but genetically validated diseases that society is falling behind on. By screening against the cellular mechanisms that drive these diseases at new scales, the Octant Navigator is charting new progress for patients.

Mission and Values

Next generation approaches to target complex diseases

We're a therapeutics company integrating and scaling new technologies.

We’re building an antedisciplinary movement to chart new approaches to drug discovery. Whether you’re a scientist, an engineer, or in operations, we’re working together to build a new type of company. It’s a challenging but fun journey.

WE WORK ON IMPORTANT PROBLEMS IN HUMAN DISEASE AND HAVE FUN DOING IT

Making new therapies depends on understanding the most complicated systems we know of — human cells. It’s hard work and a long road, but there’s also a lot of fun along the way (if there's a way to make something a competition, lookout!).

RAPID PROGRESS HAPPENS WHEN TEAMS INVENT NEW WAYS TO SEE THE WORLD

From genetic engineering, to chemical synthesis, to automation, to computation, we are equipped with technologies society couldn’t have even dreamed of a decade ago. It enables us to solve complex therapeutic problems in ways nobody else can!

INNOVATORS AT HEART, WE SUPPORT EACH OTHER TO TAKE RISKS AND GROW

We’re combining technologies to decode the complexity of disease and build better therapeutics. Direct with each other, we stretch Octonauts towards the next breakthrough. We’re serious about recruiting and developing the best people in drug discovery.

WE’RE ON A MISSION TO FIGHT DIFFICULT DISEASES; JOIN US

These are early days of a new era of drug discovery: targeting the complex cellular mechanisms that drive disease. There are patients out there waiting for us and you can make a difference for them.

Daniel Szczepankiewicz

Daniel is an organic chemist with a background in synthetic methodology, high-throughput experimentation, and phenotypic screening. He earned his Ph.D. in Organic Chemistry at the University of Illinois at Urbana-Champaign (UIUC), co-advised under the synthetic chemist Prof. David Sarlah, and the chemical biologist Prof. Angad Mehta.

Within Prof. Sarlah’s lab, Daniel worked to develop the platform now dubbed “Reaction Mining”, where he and his coworkers utilized artificial mass is otopologue distributions to autonomously discern the occurrence of reactions by LC/MS. He then demonstrated the utility of this system in high-throughput screens to map the “reaction scope” of metal catalysts, towards the goal of creating an automated method to discover novel chemical reactivity.

In Prof. Mehta’s lab, Daniel applied the same principles of high-throughput methodology towards the development of a phenotypic screen targeting viral RNA-capping enzymes, specifically the SARS-CoV-2 Nsp14 and MPoxVD1/VD12 complex. His work entailed the miniaturization of the system to a robust 384-well plate format, and its evaluation against a wide variety of small molecule inhibitor candidates. He carried out de novo synthesis of hypothesis-driven and computationally designed analogues, and evaluated the activity of diversity-oriented compound collections in high throughput assays.

When he’s not at Octant, you can find Daniel in the woods identifying wildflowers and edible plants, tending to his garden, or in the kitchen cooking with friends.

Feng Zhang

Core Institute Member - Broad Institute

Feng Zhang is a core institute member of the Broad Institute of MIT and Harvard, as well as an investigator at the McGovern Institute for Brain Research at MIT, the James and Patricia Poitras Professor of Neuroscience at MIT, and a professor at MIT, with joint appointments in the departments of Brain and Cognitive Sciences and Biological Engineering. Zhang is also an investigator at the Howard Hughes Medical Institute.

Zhang is a molecular biologist developing and applying novel molecular technologies for studying the brain. Zhang pioneered the development of genome editing tools for use in eukaryotic cells – including human cells – from natural microbial CRISPR-Cas9 systems. He and his team have adapted multiple other CRISPR systems for use as genome engineering tools, including RNA-targeting CRISPR-Cas13 systems and CRISPR-associated transposon systems, which can be used for gene insertion.

Zhang leverages CRISPR and other methods to study the genetics and epigenetics of human diseases, especially complex disorders, such as psychiatric and neurological diseases that are caused by multiple genetic and environmental risk factors and are difficult to model using conventional methods. His lab’s tools, which he has made widely available, are also being used in the fields of immunology, clinical medicine, and cancer biology, among others. His long-term goal is to develop novel therapeutic strategies for disease treatment.

Zhang is a recipient of many awards including the Canada Gairdner International Award, the Tang Prize, the Blavatnik National Award for Young Scientists, the Albany Medical Center Prize in Medicine and Biomedical Research, the Lemelson-MIT Prize, and the Keio Medical Science Prize. He has also received technology innovation awards from the Paul G. Allen Family, McKnight, New York Stem Cell, and Damon Runyon foundations. Zhang is an elected member of the National Academy of Sciences and the American Academy of Arts and Sciences.

Zhang received his A.B. in chemistry and physics from Harvard College and his Ph.D. in chemistry from Stanford University.
