VAST Data, maker of high-capacity flash storage for enterprises, raises $100M Series C led by Siemens at a $1.2B valuation, bringing its total raised to $180M
VAST Data, a startup that has come up with a cost-effective way to deliver flash storage, announced a $100 million Series C investment today …
Context & Ripple Effects
VAST Data's $100M Series C, led by industrial giant Siemens at a $1.2B valuation, lands one week after rival Cohesity pulled in $250M at a $2.5B valuation — a sign that cost-effective flash for enterprise data had become a funded battleground rather than a niche bet.
The round now reads as the entry point of an unusually steep arc: VAST went on to raise $82M from Tiger Global at $3.7B just over a year later, then $118M at $9B by late 2023, with its positioning shifting from cheap flash toward unified AI-era data infrastructure.
First-order effects
- VAST gains $100M and a strategic industrial backer in Siemens, taking total raised to $180M to scale its high-capacity flash platform against better-capitalized competitors like Cohesity.
Second-order effects
- Cohesity, already out-raising VAST on every metric at this point, faces pressure to justify its premium valuation as VAST's cost-per-flash pitch matures into direct competition for the same enterprise workloads.
Third-order effects
- If the pattern holds, storage vendors that reposition around AI data management command step-change valuations — VAST's path from $1.2B to $30B across the corpus suggests the market repriced flash economics as AI infrastructure, not commodity hardware.
The trend: Enterprise storage is being repriced as AI infrastructure, with each successive VAST round marking the market's widening gap between cheap-flash incumbents and AI-native data platforms.
