Struggled to justify enterprise adoption but have valued broader developer accessibility
If I could change or add anything to improve C3 AI, I would suggest making it not just an AI platform, but a data and AI combined platform, as bringing in data management elements, governance, and cloud features is critical. The real AI and modeling represent only 20 percent of what is needed; there is over 80 percent in the rest of the world that should be addressed. Given Tom Siebel's deep understanding of corporate work and his network, integrating C3 AI with other ERP solutions such as Oracle, SAP, or Microsoft is essential. If C3 AI can be an enterprise platform, embedding more data elements and ensuring seamless integration with other ERP solutions would significantly enhance its capabilities and attractiveness. If someone told me that they have SAP, and C3 AI can seamlessly integrate the data and perform action calls between SAP, allowing me to operate on C3 AI as I would on SAP, that would be a killer feature for me. I would suggest avoiding traditional licensing sales as it is too expensive; the starting price is too high. Considering a subscription model or a pay-per-use model is the best business structure for AI or data solution vendors. The pay-per-use model benefits usage, as the more you use, the more successful you become with the platform.

Targeted prospecting has increased campaign success and accelerates pipeline growth
The best features ZoomInfo offers include prospect call numbers, account-based prospecting and insights, integration with other systems, prospect contact information, and positioning with each company. I love the advanced search option which allows us to narrow down search results. I find myself using all of the features the most because they are very helpful and robust as they provide detailed company information where we are able to look at that company and know what we will do after that. ZoomInfo provides prospect contact information and position with each company. It provides advanced search options which allow us to narrow down search results easily and make data-driven decisions easily. Tracking people movement is easy, and Account IQ on accounts most likely to engage is very good. ZoomInfo has positively impacted our organization since we started using this tool by streamlining potential contacts in our organization. It speeds making contact by providing accurate email and phone numbers. It fits into our sales pipeline by transferring data directly to Pipedrive. Since using ZoomInfo, we have seen an increase in our sales campaign by fifty percent. We also achieve better account booking targets. The intent-based approach gives us better conversion.

Pros

"The biggest strength of C3 AI is how much it handles in one platform: data integration, model deployment, governance, monitoring, and application development."

Cons
