Tel Aviv-based Zesty, which helps cut cloud costs by automatically scaling resources to demand, raised a $75M Series B led by B Capital and Sapphire Ventures
Context & Ripple Effects
Zesty's $75M Series B, led by B Capital and Sapphire Ventures, roughly doubles the $35M Series A it raised from Next47 less than a year earlier — a fast step-up for a Tel Aviv team automating cloud resource scaling against demand.
The round lands in a category where funding keeps escalating: Vantage followed with a $21M Series A months later, Datafy took a $20M seed for autonomous storage optimization, and ScaleOps eventually reached a $130M Series C at an $800M+ valuation. Zesty's raise is an early marker of how much capital cloud-spend tooling would attract.
First-order effects
- Zesty gains the balance sheet to push its AI-driven scaling platform deeper into enterprise accounts, while B Capital and Sapphire Ventures — the latter fresh off closing a $1B late-stage fund — add a cloud-cost bet to their portfolios.
Second-order effects
- Rivals are forced to match the pace: Vantage and ScaleOps each raised larger rounds on shorter timelines, turning cloud cost optimization into a land-grab where funding size itself becomes a sales signal to CFOs.
Third-order effects
- If the pattern holds, automated spend management hardens into a standard layer of the cloud stack — bought alongside compute rather than audited after the bill arrives — with Tel Aviv repeatedly supplying the vendors (Zesty, Datafy, Act Security) that sell it.
The trend: Cloud cost optimization is shifting from manual FinOps review to autonomous, venture-funded platforms, with round sizes climbing as enterprises treat spend control as core infrastructure.
