Every month, Ramp processes billions of dollars in business expenses on its cards. And every month, we rank the new vendors that customers are purchasing from for the first time to give you a glimpse into emerging market trends, companies on the rise, and much more.
Our May list shows the evolution of the AI software landscape, with several newcomers appearing on the list for the first time, including specialized AI tools growing faster than some model companies themselves. OpenAI maintains top spots on our lists, but we are seeing dramatic growth in companies that enable businesses to build and deploy their own AI applications.
Here’s a breakdown of the top SaaS vendors last month:
By new customer count | By new card spend |
|---|---|
1. OpenAI | 1. turbopuffer |
2. Cursor | 2. HubSpot |
3. Canva | 3. Carta |
4. LinkedIn | 4. Snowflake |
5. GoDaddy | 5. Vanta |
And the fastest-growing vendors:
By largest percentage change in new customer count | By largest percentage change in new card spend |
|---|---|
1. OpenAI | 1. turbopuffer |
2. Manus AI | 2. Snowflake |
3. Maxon Computer | 3. Vanta |
4. Jasper AI | 4. Deepgram |
5. Tango.ai | 5. Silicon Mechanics |
Top takeaways
- OpenAI continues to add customers faster than any other business on Ramp’s platform. Our recently launched Ramp AI Index shows business adoption of OpenAI growing faster than competitor model companies.
- Rocketing to the top of our list on new card spend is turbopuffer, a search engine that helps companies efficiently find and retrieve information from their data to feed into AI systems.
- Vector search product capabilities make turbopuffer stand out. The system delivers exceptional retrieval latency in both hybrid and vector searches, scales well to billions of vector entries, and offers strong org-level separation. It’s a solid offering that technical teams should keep a close eye on.
- Jasper's AI writing tool, purpose-built for marketers, and Deepgram’s voice transcription software also posted big growth, showing demand for dedicated AI software solutions even as the foundational model companies continue to expand their reach and capabilities.
- We’re not surprised to see Snowflake among the top growing vendors. Snowflake’s Cortex suite of products allows LLMs and semantic functions to embed intelligence directly into existing SQL workflows and tools. This approach is expanding what data teams can build without reinventing their stack, making advanced AI capabilities more accessible and operationally seamless.
See you next month.
“I assumed I would have to choose between speed and control. What I found is that you can have both. A well-designed system takes friction out, for the finance function and for everyone else.”
Justin Webster
CFO, Denver Broncos
“A well-run district should not have to choose between getting work done at the school site and keeping control of the dollars behind it. We're not hiring more people to do more jobs, so we have to be smarter about the process. With Ramp, the purchase, the receipt, and the record stay together from the start. ”
Nick Brizeno
Director of Purchasing, San Marcos Unified School District
“In senior living, scale only works if the communities still feel personal. We needed the back office to carry more of the complexity, not the people serving residents. Ramp helped us build that infrastructure, so the experience in the community could stay human.”
Ryan Cole
CFO, Agemark Senior Living
“AI is moving faster than the finance context around it. Prices change, models change, and the value is not always obvious from an invoice. We needed enough detail to know which bets deserved more investment — and which ones did not.”
Greg Cooley
Controller, AngelList
“Invoices, cards, tokens. The categories change but the principle doesn't: know where the money is going, remove the work around it, and make sure the spend is worth it.”
Maciej Mylik. Finance
ElevenLabs
“We weren’t trying to retrofit an old finance system. We had a blank canvas, and Ramp gave us the foundation to build a global finance function of the future.”
Justin Dourado
Director of Finance, Othership
“There's just no surprises anymore. No more waiting two months to find out how a job did. We know how it's doing as it's happening.”
Erich Kuss
Financial Systems Manager, Infinity Home Services
“More token spend isn’t proof that AI is working. Less isn’t proof that it isn’t. What matters is whether we’re buying the right level of intelligence for the work. Ramp lets us make that judgment in the same place we manage every other type of spend.”
Cody Nutt
Senior Director of Business Systems, Daxko
