STEM CELLS UNLOCKED
Syntax Bio is a preclinical-stage biotech company overcoming the longstanding challenges in stem cell-derived therapies by directly controlling and accelerating cell differentiation.

Syntax’s proprietary Cellgorithm technology mimics human development to generate a wide diversity of functional cell types to enable new product opportunities.
HUMAN DEVELOPMENT
Sequential coordinated cues between embryo + mother

Fast and precise; any cell

Pre-programmed seqential regulation in the right order; one-time delivery

Mimics development & native function; fast; any cell

Reduced growth factor requirements; Cellgorithm differentiations use fewer media steps
The Syntax platform provides customizable, epigenetic instructions to program step-wise cellular differentiation processes



Syntax is a force multiplier for existing cell therapy programs by making discovery faster, less costly and scalable, while also enabling patient access and new product opportunities.

ACCELERATED
DISCOVERY
Cutting differentiation timelines from months to days translates to faster process optimization and preclinical studies, accelerating time to IND

pipeline
expansion
Wide diversity of cell types that maintain native function increases indication space and ability to address larger disease areas

enhanced
scalability
A shorter and more reliable differentiation process improves patient access, reduces manufacturing costs, and decreases variability, phenotype drift and supply risks

collaboration business model
Biopharma discovery partnerships structured with upfront R&D payments, milestone-based fees, and royalties, making Syntax capital-efficient, while also capturing significant downstream economics
“Efficiently differentiating our cells is our largest issue. The time and effort required are immense.”
