About Us

Novel therapeutics for complex diseases

Octant is scaling drug discovery to navigate the complexity of human disease

What we do

Octant is a therapeutics company building drugs that match the complexity of human diseases.

We are building drugs with novel mechanisms of actions guided by massive datasets in engineered human cells that unlock insights between genetics, chemistry, biochemical function, and disease phenotypes. Our platform uses synthetic biology, high throughput multiplexed assays, synthetic chemistry, and computation to engineer and interrogate drugs, proteins, and signaling pathways at unprecedented scales.

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, we have more information than we dreamed we’d ever had, and we still have no idea where to start-- what exactly to drug in the first place? 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. We’ve set out to tackle very hard problems in multi-factorial diseases. Because if we don’t do it, who will?

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 seriously hard problems. We have fun doing it.

We’re hacking the most complicated systems on the planet. It’s hard. We keep our sense of humor about it (if there’s a way to make something a company competition, lookout).

We use unconventional approaches to tackle challenges others aren’t tackling. If we won’t do it, who will?

From gene sequencing, to synthesis, to editing, to automation, to compute, society is equipped with technologies we couldn’t have dreamed of ten years ago. Why do what everybody else is doing when there’s so much more to be done?

Innovators at heart, we support each other to be bold and take risks.

We’re mixing and remixing technologies to decode and target disease. We’re straight with each other, kind to each other, and stretching each other towards the next breakthrough.

We’re on a mission to chart a new type of drug discovery. Join us.

These are early days of the next age of drug discovery. Come invent the future with us.

Conor Howard

Conor is a protein biochemist and molecular biologist by training. He is currently employing Octant's multiplex capabilities toward the optimizing and scaling of our Deep Mutational Scanning (DMS) approach, with the goal of harnessing this technology as a tool for rational genetics- and structure-driven drug design.

Conor received his PhD from the University of California, San Francisco in the lab of Adam Frost. There he worked on the biochemical and structural determinants of Ribosome-associated Quality Control (RQC). Prior to this he did his undergraduate work at UC Berkeley, where he worked under Liam Holt studying the evolutionary plasticity of kinase specificity and poly-glutamine repeat expansions in yeast. Before graduate school Conor also spent some time at the University of Copenhagen in Rune Linding's lab studying the proteomic effects of cancer therapies. Conor thrives working at the intersection of many disciplines and is fascinated with how biology emerged in the universe. He believes mechanistic dissection of molecules in the context of mutational plasticity can help tackle some of the most complex problems in biology and disease.

Outside of work you'll find Conor traveling, skiing, scouting new breweries, playing tennis, experimenting with hot sauce recipes, and exploring unusual agave spirits.

Johan Enquist

Johan has spent the last 7 years in biotech working with metabolic disease and weight loss. As an employee of Carmot Therapeutics Johan spearheaded the in vivo pharmacology effort, establishing all in vivo models necessary to push an in house project from inception to Phase 1 clinical trials.

Johan spent his early education getting an MSc in cell and molecular pharmacology at Lund University (1999), with a focus on intracellular movements of GPCRs. Johan followed up his MSc with a PhD from Lund University (2007) extending his studies from his undergraduate degree in GPCR pharmacology - exploring several families of GPCRs. During his postdoctoral fellowship at UCSF (2007-2013) Johan applied his findings from his MSc and PhD to animal models of addiction and tolerance, learning crucial methodology in physiological and behavioral readouts in rodent models, drug delivery and survival surgery techniques.

Along the way Johan has taught medical and biomedical students (lecture series), trained research students, technical staff and scientists, and managed technical staff and scientists in cross functional research teams in both academia and biotech.

Debora Marks

Professor of Systems Biology — Harvard and Associate Member, Broad Institute

Debora is a mathematician and computational biologist with a track record of using novel algorithms and statistics to successfully address unsolved biological problems. She has a passion for interpreting genetic variation in a way that impacts biomedical applications. During her PhD, she quantified the potential pan-genomic scope of microRNA targeting and combinatorial regulation of protein expression and co-discovered the first microRNA in a virus. As a postdoc she and her colleagues cracked the classic, unsolved problem of ab initio 3D structure prediction of proteins using a maximum entropy probability model for evolutionary sequences. She has developed this approach to determine functional interactions, biomolecular structures, including the 3D structure of RNA and RNA-protein complexes and the conformational ensembles of apparently disordered proteins. Her new lab at Harvard is interested in developing methods in deep learning to address a wide range of biological challenges including predicting the effects of genetic variation and sequence design for biosynthetic applications.
