L3 Labs is a brain-longevity biotech. We engineer non-invasive medicines that rejuvenate the aging brain, restoring youthful cognition and extending human healthspan.

Longevity is won or lost in the brain. As we age, the brain loses synapses, plasticity and the capacity to renew itself, and that decline sets the ceiling on healthspan. L3 Labs exists to lift that ceiling.

Our platform turns the nose into a factory for the brain's own regenerative proteins: a non-invasive, self-administered intranasal mRNA medicine that programs cells in the nasal lining to make therapeutic proteins, which then travel the nose-to-brain route. Restore, don't just slow.

Lead program L04 rejuvenates the healthy aged brain and is entering preclinical safety. A second asset, L05, works through a complementary mechanism and is in efficacy testing.

The clinical on-ramp runs through Mild Cognitive Impairment and early Alzheimer's disease: accelerable, biomarker-based pathways that de-risk the longevity vision.
