Simplify's Take

What believers are saying

  • March 2026 fundraise gives Kleiner Perkins dry powder during the AI super-cycle.
  • 2026 bets on Mirendil, Profound, K2 Space, and CuspAI show dealflow remains elite.
  • SpaceX's June 2026 listing and Figma's July 2025 IPO validate long-horizon venture returns.

What critics are saying

  • Five partners after Ev Randle and Annie Case departures strains sourcing and portfolio support.
  • Ellen Pao's discrimination case still stains recruiting and founder trust around Kleiner Perkins.
  • If AI deal prices compress before exits, the $3.5 billion 2026 funds underperform badly.

What makes Kleiner Perkins unique

  • March 24, 2026 KP22 raised $1 billion early-stage capital and $2.5 billion growth capital.
  • Kleiner backed Figma, SpaceX, Harvey, and OpenEvidence, proving repeatable top-tier platform access.
  • Five-partner team stays concentrated, letting Mamoon Hamid move fast on AI deals.

Flapping Airplanes raises $1B at $6B valuation as investors back AI research labs

Flapping Airplanes, a year-old artificial intelligence startup, has raised $1 billion at a $6 billion valuation. It is the latest example of investors backing newer AI research labs that have yet to launch commercial products. Index Ventures and Lux Capital led the round, which is set to be announced Wednesday. Sequoia Capital, Alphabet Inc.'s GV, and Kleiner Perkins also took part. The valuation, which includes the new money, has quadrupled from a prior round in January. Founded in late 2025, Flapping Airplanes is one of a growing number of so-called AI neolabs, startups that focus first on research.
