Israel-based Weka, which makes data management tools for AI, ML, HPC, and research, raised a $135M Series D at a $750M valuation, after raising $73M in January

Context & Ripple Effects
Weka's file-system business has been compounding through the AI buildout: an HPE-led $31.7M Series C in 2019 positioned its parallel file system for AI and technical workloads, and this $135M Series D comes just months after a $73M raise in January 2022 — two rounds inside one year at a $750M valuation.
The bet paid forward: by May 2024 Weka had converted the momentum into a $140M Series E at a $1.6B post-money valuation led by Valor Equity, more than doubling the price of this round. It also sits inside a wider Israeli data-infrastructure cohort raising against AI demand, alongside NeuroBlade's processing-in-memory push and Noogata's analytics tooling.
First-order effects
- Weka gains roughly doubled capitalization within twelve months to scale its parallel file system sales into AI, ML, and HPC customers whose GPU clusters need faster data pipelines.
- HPE, which led the 2019 Series C, sees its strategic bet re-priced upward — the $750M valuation validates the enterprise-storage incumbent's early positioning in AI-optimized file systems.
Second-order effects
- Rival storage and data-management vendors serving AI/HPC buyers face a competitor with fresh war chest and pricing flexibility, forcing them to accelerate their own AI-native product roadmaps or acquisition searches.
- Israeli data-layer startups like NeuroBlade and Noogata benefit from the halo: investors underwriting Weka's thesis are primed to fund adjacent pieces of the same AI data stack.
Third-order effects
- If the cadence holds — and the subsequent $1.6B Series E suggests it did — AI infrastructure software becomes a category where valuations compound across successive rounds faster than traditional enterprise storage ever repriced, concentrating capital in a small set of data-layer platforms beneath the model builders.
The trend: AI infrastructure finance is compressing fundraising cycles, with data-layer vendors like Weka doubling valuations across back-to-back rounds as GPU-driven storage demand outpaces supply.
