Every month, billions of dollars get processed on Ramp cards for business expenses. And every month, we share the new vendors that customers are purchasing for the first time, to give you a glimpse into emerging market trends, companies on the rise, and much more.
While our top vendors list showed only minor shifts, our list of fastest growing vendors highlighted a growing space in AI software companies: Lovable, Codeium, and Cursor are among the fastest growing companies on Ramp. All of them create AI-powered code editors that allow developers to build software faster, sometimes without writing any code themselves. You’ve probably heard it called “vibecoding.”
Here’s a breakdown of the top SaaS vendors last month:

Other standouts:
- OpenAI topped our list again. This time, likely boosted by the release of 4o Image Generation. Sam Altman, CEO of OpenAI, reported adding a record breaking one million users in one hour.
- Anthropic continues to gain users but is adding fewer users per month than OpenAI. A strong competitor in a crowded field of model companies.
- But human graphic design is not dead. Canva, the design platform, appeared in both of our top 5 lists, by both new customers added and fastest growth.
- LinkedIn continues to grow on the strength of their data enrichment product, which we wrote about here.
See you next month when we publish our top vendors for April.

“In the public sector, every hour and every dollar belongs to the taxpayer. We can't afford to waste either. Ramp ensures we don't.”
