Plant-Derived Exosome-Like Nanovesicles (PELNVs) via Continuous Tangential Flow Filtration

Rejected

This concept did not clear the framework. The reasoning is published in full below.

Why it failed

• No head-to-head evidence

Assessment

Utilizes continuous tangential flow filtration to process cheap agricultural waste into premium regenerative skincare nanovesicles. The process entirely bypasses capital-intensive ultracentrifugation, yielding high throughput and massive unit margins. Strong regulatory tailwinds as botanical extracts ensure rapid mass-market adoption.

A rejection is not a claim that the science is wrong. It means the venture case did not survive: the comparator was not what the buyer actually buys, the comparison was not like-for-like, the advantage fell short of a step change, or the capital and time to first revenue were prohibitive.
