Immune
Bridge

We use the highest possible quality starting material: young, healthy, and disease-free umbilical cord blood stem cells. This enhances therapeutic efficacy and enables intentional leveraging of nature’s innate diversity through accessing the hundreds of thousands of umbilical cord blood units currently frozen in public banks.

Our ML-powered screening system enables affordable and efficient sampling of donors, engineering constructs, manufacturing processes, and cell types to identify or design optimal clinical candidates for almost any disease.

Our proprietary stem cell expansion technology enables consistent, affordable, and truly scalable manufacturing of HSCs, NK cells, T cells, red blood cells, neutrophils, mitochondria, and more – bridging discovery and translation to make cell therapies safe, accessible, and effective for the patients who desperately need them.

Building the next generation of cell therapies

The Problem

Cell therapies face key challenges that limit their efficacy and accessibility:

High Cost

Source Variability

Poor Manufacturability

Suboptimal Safety Profiles

Long Development Timelines

Despite these significant hurdles, companies and developers often choose to work independently – and therefore inefficiently – rather than build on the advances of others.

They design new therapies as quickly as possible, without taking the time to properly build screening and scalable manufacturing processes alongside them.

Then they race these suboptimal or variable cell products into the clinic, competing for limited patients and funding. As a result, progress remains frustratingly slow and billions of dollars have been wasted. Even more devastating is the fact that countless patients have been treated with therapies that are ineffective at best or dangerous at worst. 

Our Solution

We aim to change this paradigm by bridging technologies together to make a real difference for patients in need.

2022

We started by building a powerful platform that integrates source screening and scalable manufacturing, thereby addressing several of the universal challenges faced by developers.

2024

Next, we validated that our processes are compatible with all major engineering modalities and can produce cells across diverse immune lineages at high purity, quality, and quantity.

2025

We are now allowing partners across academia and industry to leverage this groundbreaking platform and build a new generation of inherently efficacious and scalable cell therapies – ensuring worldwide access to cures for diseases previously considered untreatable.
