Recommendation: WATCH with a conditional lead, not a pass. ColdChain IQ shows genuine quality—€3.8M ARR, 118% NRR, and a 2.3-month hardware payback backed by an 88/100 execution signal—but it sits in a crowded, commoditizing field where Sensitech, ELPRO, and Berlinger can replicate the sensor-plus-dashboard stack. The single strongest reason to invest is the compounding switching-cost moat: validated GxP/GDP audit reporting, once embedded in a pharma customer's compliance workflow, is genuinely sticky and hard to rip out. The single strongest reason against is that the "predictive" differentiation is scientifically unproven (no false-positive/lead-time data), meaning the premium could collapse to a price war while 40% hardware capital intensity drags margins and multiples. Entry plan: lead $8.0M for ~12% at roughly $55M pre, but hard-cap exposure at $5.5M and stage the second tranche on two diligence gates—gross logo retention (not just NRR) and documented excursion detection accuracy. Reserve ~$12M for pro-rata. Size at ~1.7% of the portfolio.
