Group Head of Data Strategy & Enterprise Governance at a consumer goods company with 10,001+ employees
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.

Cst Csd at a university with 1,001-5,000 employees
Improves team writing clarity and consistency but has needed more context-aware and faster support
From my experience working with the CST, where communication needs to be clear, accurate, and timely, a tool such as Writer could definitely be helpful, but there are a few areas where it could be better. One thing is that sometimes AI suggestions from Writer can feel a bit too generic or not fully context-aware, especially when dealing with sensitive communication or student-specific situations. In those cases, I would still need to manually adjust the tone to make sure it's appropriate and empathetic. Another thing is that in a fast-paced environment such as CST, where I'm managing scheduling and coordinating with students and faculty, I would want Writer to be very quick and seamless. If it slows down the workflow or requires too much interaction, it can be frustrating. It would also be helpful if Writer could better adapt to institution-specific language or policies, since a lot of our communication follows certain guidelines. Overall, Writer is useful for improving clarity, but I would appreciate seeing it become more context-aware, faster, and better aligned with real-world workflows, especially in environments such as student services.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"One of the best features C3 AI offers is that you do not need to learn Python or any specific machine learning programming language; you can use C3 AI with JavaScript."
"In the first phase alone, there was approximately $90 million in savings, which reduced about 5% of inventory."
"I have noticed improvements in efficiency, reduced downtime, and time saved for my team, as it is quite integrated through the source ML pipeline to report to general customer UI, functioning as one platform that takes care of everything, thus improving efficiency, optimization, and increasing project deliverables."
"The biggest strength of C3 AI is how much it handles in one platform: data integration, model deployment, governance, monitoring, and application development."
"Overall, Writer is mainly used to polish content, maintain consistency, and make writing more professional, especially in work or team settings."
"Writer is the best choice and can help in formatting, editing, and converting files into any format."
"I think they should actually consider using Writer because it has helped me over the years to shape my words, help me with grammatical structure, and word construction."
"Writer has positively impacted my organization and my work by helping to reduce the daily manual effort of creating reports through the use of AI, allowing us to invest more time in other important activities."
 

Cons

"The reason I chose eight out of ten is that as a user of C3 AI, I found the operational aspect not easy to understand; it is a bit tricky, and you should have more core knowledge to navigate C3 AI."
"However, I sometimes hear from colleagues that hallucination is an issue."
"We even failed to open any doors for C3 AI; there are no smaller wins, learning opportunities, or process improvements, even if the main goals were not met."
"C3 AI can feel very enterprise-heavy. For smaller teams, it may feel excessive."
"One thing is that sometimes AI suggestions from Writer can feel a bit too generic or not fully context-aware, especially when dealing with sensitive communication or student-specific situations."
"My experience with Writer's pricing, setup cost, and licensing is actually very challenging."
