We expand living B, T and NK cells from a single ~3 mL blood draw and keep them functional for 21 days — long enough to test dose, combination and time on a faithful model of one patient's immune system.
Immunotherapy response is decided by the patient's own immune system — yet the moment those cells leave the body they begin to fail. Within 24 to 48 hours a standard preparation is no longer functional, and NK cells go first. So the industry tests on models that contain no immune compartment at all, and finds out what actually happens in Phase II.

Our platform takes a routine ~3 mL clinical blood draw and turns it into an Immune Twin — a living, queryable model of one person's immune system that stays functional for at least three weeks.
It is built on three proprietary layers. Each one removes a constraint that has kept patient-specific immune testing out of reach.
Request the technical briefB, T and NK cells are isolated simultaneously from about 3 mL of blood — a volume compatible with routine care and with immunocompromised patients, where conventional methods need 10 to 30 mL.
Proprietary 3D-matrix niches preferentially expand immortalised immune cells while progressively eliminating the rest, holding multi-lineage function for 21 days or more without losing the patient's genetic and phenotypic signature.
A 30+ gene panel, cytometry and secretome data feed a model that ranks drug response, toxicity and combination synergy per patient — documented for traceability under the EU AI Act.
Measured functional viability of multi-lineage immune cells after sampling. Everything to the right of the red band is testing that simply cannot be done on a standard preparation.

B, T and NK cells captured and kept functional together — NK biology is the hardest to preserve and the most predictive for cell therapy.
About 3 mL — a routine draw that fits inside standard care with no additional invasive procedure.
21 days or more of measured multi-lineage function, from the same original sample.
Dose, schedule, combination and exhaustion studied over time on one patient's own cells.
A 30+ gene signature paired with functional readouts, built to be auditable rather than a black box.
From guesswork to guidance.
