Details
Fund III: $232M raised
Nearly doubles Fund II's $121M; total AUM now $400M. Fund growth: $17M (Fund I, 2020) → $121M (Fund II) → $232M (Fund III) — unusual compounding even for top-performing VC firms.
Check sizes: $500K–$25M
Standard range $500K–$15M; select growth-stage follow-ons up to $25M, covering pre-seed through Series B.
Solo GP at $200M+ scale
Nathan Benaich is the sole decision-maker — notable at this fund size, where most VCs employ multiple partners.
Unicorn portfolio companies
Black Forest Labs (image generation AI) and ElevenLabs (voice AI) are both portfolio companies at unicorn valuations.
Exit track record
Adept acquired by Amazon; Graphcore acquired by SoftBank — two significant AI exits that validate the fund's early-stage thesis.
Transatlantic mandate
Targets both Europe and North America — rare for a European solo GP — signaling ongoing confidence in the European AI talent pipeline.

What This Means
For AI founders and co-investors, Air Street's growing fund size and unicorn-level track record make it one of the most credible signal-setters in early-stage European AI investing. The rapid AUM growth from $17M to $400M in five years mirrors the broader institutionalization of AI-focused venture capital. European founders now have a well-capitalized, AI-specialist lead investor that can follow through Series B without requiring a US relocation to access serious capital.
