Briefs (same window)

Fluidstack — reported $1.5B at $18B+ (Jane Street)

Forbes reporting summarized by trade wires: neocloud Fluidstack closed a $1.5B round led by Jane Street at an $18B+ valuation — more than double the $7.5B July mark — against a previously disclosed multi-year Anthropic capacity narrative. Treat as reported until a primary company release. Same week as Crusoe’s Jane Street offtake story: trading firms are now central to GPU-cloud financing.

HiBob — $166M led by Salesforce (~$3.2B)

HiBob announced a $166M investment led by Salesforce with Farallon, valuing the HR/people platform near $3.2B (up from ~$2.7B in 2023). Company materials emphasize organizational intelligence for AI-relevant workforce context across 5,500+ customers. Fits the same Salesforce strategic-check pattern as Wonderful.

Also noted (thin / skip for deep dive)

  • Hivebotics — $6M Series A (Vertex Ventures SEA & India) for Singapore robotics cleaning (Business Times, Sep 4).
  • Sirdab — $10M Series A (Elm / BECO) for Saudi/GCC logistics infrastructure (Wamda, Sep 3).

Themes

  1. Neoclouds price like utilities once offtake is visible (Crusoe, Fluidstack).
  2. Cyber splits: enterprise CNAPP independents (Upwind) vs. consumer ARR machines (Guardio) vs. edge category creation (Huskeys).
  3. Enterprise AI OS keeps compounding (Wonderful) while inference routing becomes its own mega-round (Gimlet).
  4. Optical + silicon capital follows GPU scarcity one layer down the stack (iPronics; compare Lyte on perception silicon).
