Experience is an engineerable output of biology.

What we do

We're building the closed-loop science + engineering stack for rational psychoactive effect design.

A molecular experience interface

Our molecular-experience interface links biology to human experience, transforming effects like clarity, presence, and motivation into quantitative design targets.

Research + development programs

Research + development programs

Our clinical programs are a sequence of human demonstrations that psychoactive effects can be decomposed, recombined, and synthesized. Our primer + probe fixed-dose combinations provide iterative testing of target psychoactive effect profiles and advance directly to human trials.

* GLP safety pharmacology; GLP single-dose toxicity/TK studies in rat and dog; genotoxicity; DMPK/ADME; MRSD achieved Fixed-dose combination safety/PK trial in healthy normal volunteers Placebo-controlled trial in patients powered for primary efficacy endpoints

The first controlled study of primer MSD-001 decomposed hallucinations and other effects from the broader hallucinogen profile. The next human study of the first primer + probe combination is designed to selectively upregulate aesthetic salience to treat anhedonia in major depressive disorder.

Additional parallel programs are designed to demonstrate de novo synthesis of novel psychoactive effects.

Discovery-stage programs optimize for single-molecule, multi-target action producing a broader range of psychoactive effects.
