What Exin Therapeutics does

We use AI and high-throughput mouse studies to discover therapeutics that modify neural activity in the brain. The initial focus is on epilepsies associated with autism and Parkinson’s disease with the potential to expand to any neurological disorder underlined by a dysfunction in neural activity. Our R&D is guided by AI models trained on high-density multimodal mouse data generated in-house. We are 3 Oxford-trained neuroscientists supported by an experienced SAB from Harvard, Science Corp (ex-Neuralink), EPFL, Meta, and UCL. In 1.5 months since landing in SF, we went from nothing to (1) opening and operating an animal lab in South SF, (2) obtaining a proof-of-concept in mice, (3) building a multimodal AI model that directs our screening approach and (4) submitting two provisional patents; all while utilizing less than 50% of our YC funding.

AI drug discovery platform for neurotherapeutics

What is your company going to make? Please describe your product and what it does or will do.

We are building an AI-driven platform that analyzes high-density multimodal mouse data to discover drugs that modify neural activity. Initially, we target epilepsies associated with autism and Parkinson's disease, but our approach could extend to other neurological disorders involving dysfunctional neural activity.

Where do you live now, and where would the company be based after YC?

We live in San Francisco, CA, and the company is based here post-YC.

Explain your decision regarding location.

We are in San Francisco to be close to biotech investors, collaborators, and research talent. Setting up an animal lab here allows fast iteration between AI insights and in vivo validation, which is key for our approach.
