Four integrated
capabilities,
one platform.

Each capability within the AVB Platform is designed to interoperate. Gene circuit outputs inform delivery optimization; bioprocess ML models are trained on delivery-adjusted expression data. The result is a compounding advantage that accelerates every program on the platform.

01

Adaptive Gene Circuit Architecture

Proprietary synthetic gene circuits that sense, compute, and respond to complex intracellular signals with sub-nanomolar precision. Our AGCA platform enables programmable cell behavior without off-target genomic disruption.

Synthetic BiologyGene CircuitsPrecision Control
02

BioProcess Optimization Engine

Machine learning models trained on 2.3 million fermentation runs continuously optimize yield, purity, and scalability. Real-time adaptive control reduces upstream bioprocess development cycles from 18 months to under 6.

ML OptimizationFermentationScale-Up
03

Modular Delivery Architecture

A library of 340+ validated delivery vectors engineered for tissue-specific tropism. Our lipid nanoparticle and viral vector libraries are de-immunized and scalable for clinical manufacturing under cGMP conditions.

04

Immuno-Sculpting Framework

Precisely engineer immune cell phenotypes through combinatorial cytokine and checkpoint modulation. Our ISF platform has demonstrated durable CAR-T persistence improvements of 4.7× in exhaustion-prone solid tumor models.

Grounded in
rigorous science.

"We don't engineer biology around what's convenient. We engineer it around what's true."

Every AVB Platform capability emerged from years of fundamental research published in peer-reviewed journals. Our scientific founders remain active contributors to the academic literature, maintaining a feedback loop between basic discovery and translational application that is rare in biotech.

Our 47 publications span synthetic biology, gene therapy delivery, bioprocess control, and computational immunology — a breadth that reflects the integrative nature of our platform and the depth of our scientific team.
