Vast.ai Named Among Fastest Growing Vendors by Ramp and Brex
Two of the largest corporate spend platforms in the US have independently named Vast.ai one of their fastest-growing vendors — not based on fundraising announcements or press coverage, but on what companies are actually spending money on.
Ramp, which tracks spend across 50,000+ businesses, named Vast.ai a breakout growth vendor in their March 2026 Velocity report. They categorized us under "Agent hosting" and noted that half the trending vendors on the platform are compute infrastructure providers. Their analysis:
"AI agent workloads are moving from prototypes to production systems, and the constraint is shifting from 'which model is best' to 'where can I run this reliably.'"
Three months earlier, Brex ranked Vast.ai #11 in their 50 fastest-growing software vendors of 2025, based on transaction data from 35,000+ customers. Fortune covered the report, highlighting Vast.ai as a key infrastructure-layer company drawing real dollars alongside Groq (#12) and Supabase (#23).
That's 85,000+ businesses across two independent platforms telling the same story.
What's driving the growth
The numbers behind these rankings reflect a shift we've been seeing on our own platform. Over the past twelve months:
- New signups grew 27x year-over-year. In February 2026 alone, more than 19,000 new users signed up for Vast.ai — compared to roughly 700 in February 2025.
- Monthly active paying customers grew 16x, from under 1,000 to over 14,000.
- GPU supply scaled to meet demand. Our marketplace now has nearly 20,000 GPUs across 5,000 machines from over 1,000 independent hosts — up 48% year-over-year.
- Revenue grew 13x, crossing seven figures per month for the first time.
This isn't growth driven by a single large customer or a one-time event. It's thousands of teams — researchers, startups, and enterprises — independently discovering that they can get GPU compute faster, cheaper, and with more flexibility on Vast.ai than anywhere else.
Why corporate spend data matters
Fundraising rounds and press mentions are leading indicators. Corporate spend is a lagging one — it only moves after teams have evaluated, tested, and committed. When Ramp and Brex both flag the same company, it means real budgets are shifting. Not pilot programs. Not free-tier experiments. Paid production workloads.
Ramp's observation that the bottleneck is moving from "which model" to "where do I run it" is exactly the opportunity we built Vast.ai for. The platform is model-agnostic, cloud-agnostic, and contract-free. Teams deploy in seconds and pay by the second. That simplicity compounds — once a team starts, their usage tends to grow.
What's next
We're investing in the areas that matter most to production teams: reliability, autoscaling, and deeper integrations for agentic workloads. The infrastructure layer for AI is still being built, and we plan to keep earning our position in these rankings month over month.
Thank you to the 100,000+ users who've signed up for Vast.ai, and to the 1,000+ hosts whose GPUs make this marketplace possible.
One more thing: we're also a Ramp customer ourselves. We use Ramp to manage our own corporate spend. Vendor and customer — it's a good sign when the tools you rely on are also relying on you.
