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.
“We’ve simplified our workflows while improving accuracy, and we are faster in closing with the help of automation. We could not have achieved this without the solutions Ramp brought to the table.”

“Our previous bill pay process probably took a good 10 hours per AP batch. Now it just takes a couple of minutes between getting an invoice entered, approved, and processed.”

“We no longer have to comb through expense records for the whole month — having everything in one spot has been really convenient. Ramp's made things more streamlined and easy for us to stay on top of. It's been a night and day difference.”

“It's great to be able to park our operating cash in the Ramp Business Account where it earns an actual return and then also pay the bills from that account to maximize float.”
Mike Rizzo
Accounting Manager, MakeStickers
“The practice managers love Ramp, it allows them to keep some agency for paying practice expenses. They like that they can instantaneously attach receipts at the time of transaction, and that they can text back-and-forth with the automated system. We've gotten a lot of good feedback from users.”
Greg Finn
Director of FP&A, Align ENTA
“The reason I've been such a super fan of Ramp is the product velocity. Not only is it incredibly beneficial to the user, it’s also something that gives me confidence in your ability to continue to pull away from other products.”
