Product-market fit in stem cell TechBio: building for workflows, not for papers
Why TechBio Fails Paul De Sousa 5/6/26 Why TechBio Fails Paul De Sousa 5/6/26

Product-market fit in stem cell TechBio: building for workflows, not for papers

Tools built for academic novelty rather than industrial workflows. Microfluidic systems too complex, expensive, slow. How to test whether your product fits real demand.

The regulatory cliff: moving from research-grade to GMP-compliant product
Why TechBio Fails Paul De Sousa 5/6/26 Why TechBio Fails Paul De Sousa 5/6/26

The regulatory cliff: moving from research-grade to GMP-compliant product

Research-grade reagents cannot enter clinical pipelines. GMP, documentation, traceability requirements. The gap between interesting lab tool and regulated product.

Toolchain fragmentation: why imaging, culture, and data systems need to talk to each other
Why TechBio Fails Paul De Sousa 5/6/26 Why TechBio Fails Paul De Sousa 5/6/26

Toolchain fragmentation: why imaging, culture, and data systems need to talk to each other

Imaging, culture, data, and automation systems built in isolation. Manual workflows dominate. Why poor integration limits adoption beyond expert labs.

Cryopreservation and supply chain fragility in clinical-grade cell products
Why TechBio Fails Paul De Sousa 5/6/26 Why TechBio Fails Paul De Sousa 5/6/26

Cryopreservation and supply chain fragility in clinical-grade cell products

Cells lose viability and function after freeze-thaw. Batch variability increases with storage. Critical for clinical trials and commercial supply chains.

Characterisation gaps: what current assays miss about stem cell quality
Why TechBio Fails Paul De Sousa 5/6/26 Why TechBio Fails Paul De Sousa 5/6/26

Characterisation gaps: what current assays miss about stem cell quality

Current assays miss subtle stem cell state shifts. Epigenetic instability, differentiation drift, and what this means for regulatory submissions and clinical outcomes.

When lab-scale biology meets manufacturing reality: where most scale-up goes wrong
Why TechBio Fails Paul De Sousa 5/6/26 Why TechBio Fails Paul De Sousa 5/6/26

When lab-scale biology meets manufacturing reality: where most scale-up goes wrong

The physics and biology of scale-up: shear stress, nutrient gradients, contamination. Where suspension culture and bioreactor platforms lose cell quality.

Reproducibility as a commercial problem, not just a scientific one
Why TechBio Fails Paul De Sousa 5/6/26 Why TechBio Fails Paul De Sousa 5/6/26

Reproducibility as a commercial problem, not just a scientific one

How batch-to-batch variability and operator-dependent outcomes block commercialisation. Why pharma partners walk away from inconsistent data.

Why ancillary technologies for stem cell science fail, and what to do about it
Why TechBio Fails Paul De Sousa 5/6/26 Why TechBio Fails Paul De Sousa 5/6/26

Why ancillary technologies for stem cell science fail, and what to do about it

Second pillar series overview examining systemic reasons TechBio ancillary technologies fail in developmental and stem cell science.
