Verdict: watch, with a conditional small check rather than a lead. Nova has demonstrated something rare at seed—real paying demand and a measurable 41% cost reduction with 99.95% uptime, proving the arbitrage genuinely works and customers will pay for it. But the single decisive reason against is structural: this is a commoditizing middle layer where hyperscalers and inference incumbents (Bedrock, Vertex, Together, Fireworks) can absorb cross-cloud routing as a native feature overnight, and a single cloud revoking spot-reseller access via ToS could collapse the business with no recourse. The "data scale" moat is not real at 22 teams. That risk-reward doesn't justify leading. Concretely: pass on the lead, but offer a $1.5–2M participating ticket for ~7–9% ownership, structured in two tranches—half now, half released on hitting $150k MRR with disclosed net revenue retention above 110% and at least two enterprise anchor contracts. Reserve pro-rata for follow-on. Cap total exposure at $3M and hold to roughly 2% of the portfolio.
