Ultrafast Periodate-Accelerated Polycatecholamine Aqueous Adhesion Promoters via Oxidative Crosslinking
Rejected
This concept did not clear the framework. The reasoning is published in full below.
What the assessment found
| Incumbent benchmark | 3M Tape Primer 94 |
| Entry application | wet-environment structural adhesion and VOC-restricted automotive/architectural detailing |
| Measured advantage | none |
| Time to first revenue | 12 months |
| Gross margin at parity | 94.7% |
| Startup CapEx | $255,000 |
| Payback from first sale | 0.1 months |
| Capital productivity | 223.15x |
| Regulatory risk | Moderate — qualification costs reported ($100,000 estimated) |
Why it failed
- Voided by: Economics undisclosed, Negative control / sub-2x, Entry application mismatch, Form-factor / handling regression, Absence search missing
Assessment
The report explicitly concedes failure on superiority and CapEx. Startup CapEx of $255,000 exceeds the $250,000 threshold, the product suffers form factor regression requiring a two-part system, thermal breakdown above 50°C undermines application fitness, and the market absence ledger is missing.
Also flagged
- Duplicate references inflating the evidence base
- Price parity asserted, not sourced
- runsheet_no_quantities
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.
