Elevated mRNA for transformative medicines

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

We are building a new class of mRNA medicines that deliver much higher protein expression and longer activity using our proprietary APEXm™ platform. This enables therapies targeting autoimmune diseases, cancer, and protein therapeutics with potency and duration not achievable by existing mRNA drugs.

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

We live and operate in San Francisco, and after YC we will continue to be based here.

Explain your decision regarding location.

San Francisco has the critical biotech ecosystem, access to talent, and investors necessary for a therapeutics startup focused on mRNA medicines. It's where we can recruit, collaborate, and raise effectively.
