THE SO WHAT
A $275M Series C at a $3B+ valuation for Celero’s coherent optics is a bet that intra- and inter-rack bandwidth—not just GPUs—will be the next hard bottleneck in AI data centers.

Twenty-nine new unicorns adding ~$63B in August—over a third under 3 years old, heavily in AI software and semis—means capital is still willing to prepay for perceived AI infra and tooling. Founders in these lanes get a funding window, but operators should expect aggressive burn and fast-moving competitors as the price of that capital.

Over $150B flowing into non-AI deeptech since early 2024 means AI is reopening the capital window for BCIs, quantum, and other long-horizon bets. Founders in these sectors should be ready to tie their story to AI-adjacent demand—compute, sensing, interfaces—while operators should watch for new dependencies creeping into their 5–10 year roadmaps.
