Technical Failure Modes & Moat Evaluation
Critical scaling chokepoints and defensibility moats.
Critical Path Bottlenecks
Thermal & Kinetic Stability
High SeverityDegradation observed at operational temperatures above 45°C under continuous duty cycles.
Mitigation Pathway: Passivation surface chemistry and cryogenic lyophilization buffers. (In Progress (60% resolved))
Supply Chain Precursor Purity
Medium SeverityReliance on single-source high-purity organometallic reagents creates inventory fragility.
Mitigation Pathway: Qualification of secondary domestic reagent synthesizers. (Identified)
Regulatory Standard Harmonization
Low SeverityLack of standardized ASTM/ISO assay protocols leads to cross-lab divergence in published yields.
Mitigation Pathway: Active working group participation with NIST and European Metrology Consortium. (Under Review)
Defensibility & Moat Verdict
• IP Defensibility: Strong Moat (Composition of Matter + Proprietary Bio-Informatics)
• Switching Barrier: Moderate (API / Droplet compatible)
