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.

Process intelligence has transformed procurement and order cycles and delivers measurable savings
Celonis can improve in several areas. The initial data modeling and continuous real-time ingestion, especially from non-standard legacy systems, can still be complex and quite resource-intensive, requiring a steep PQL learning curve for non-technical users. Simplifying the interface for business stakeholders would significantly accelerate the process. I think introducing a natural language to query interface would allow business users to query data without writing long PQL. Streamlining guided onboarding flows and offering modular plug-and-play dashboard templates tailored to specific roles would shorten ramp-up time for daily users. I think more transparent and predictable consumption-based pricing models would be helpful as data volume scaling can get costly quickly. I would also love to see native, real-time streaming connectors for unstructured data such as emails and support tickets. The learning curve for new users of Celonis is one of the pain points I raised earlier, and I find it to be quite steep.

Quotes from Members

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

Pros

"The biggest strength of C3 AI is how much it handles in one platform: data integration, model deployment, governance, monitoring, and application development."
"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."
"We can observe the flow and invoices."
"In my Celonis experience, it is easy to use and has higher AI capabilities."
"Celonis’ Process Cockpit is valuable."
"Celonis is intuitive, powerful, and user-friendly."
"We can use it to discover processes and mitigate the mistakes in the process."
"Its usage is relatively straightforward after the UI is set up, and there's a lot of pre-built analysis that can be utilized, which saves a lot of time, and overall, it is a good product."
"It is a very stable product, and there are no issues."
"With the help of data mining, we can identify different costs. Celonis does background research into the data from the different solutions and puts it into the dashboard and so we can see the differences between the pricing over the previous years."
 

Cons

"C3 AI can feel very enterprise-heavy. For smaller teams, it may feel excessive."
"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."
"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."
"The solution needs to implement more automation aspects into the product. Right now, it's lacking."
"The cost could be improved."
"The one thing that could be improved is the guides are not getting updated to cover new features and upgrades, which means we can't use them at their full potential."
"Similar to what SAP is doing with S/4HANA, Celonis should allow business users to create their own analytics tab. In my previous organization, business analysts were the only ones who were actively building these reports with Celonis, whereas SAP platforms are now allowing the business users to create their own reports with graphics and all other things based on the data that is presented. This is one thing that Celonis needs. Currently, just the technical teams are doing that. Sometimes, when we were looking at five years of data, it used to take up to 3 seconds. It wasn't bad, but we had to wait a little bit. It probably also had to do with the server. I don't know if it can be used on mobile devices. If not, that will be the way to go. They should mobilize it to allow people to see these reports on their mobile devices."
"For example, we would like to see improvement of the simulation capabilities to include a BPMN-compliant modeler. That is, we would like to be able to connect the simulation to the BPMN modeler. I think it's one of the features that is missing in Celonis."
"Similar to what SAP is doing with S/4HANA, Celonis should allow business users to create their own analytics tab."
"In the solution, you have access to how the process is, and are able to integrate that with other systems that allow you to make changes to the process itself, this process can be improved."
"The support costs are very high."
 

Pricing and Cost Advice

Information not available
"Though Celonis is a bit pricey, it is worth it."
"The product is pretty expensive but reasonable."
"Pricing-wise, Celonis is a five out of ten right now because my clients just started with the solution. When my clients start looking at scaling Celonis, the cost will grow. Every user has an additional charge, and every gig of data you bring in costs extra."
"The solution is quite expensive."
"I rate Celonis' pricing a ten out of ten because it is expensive."
"Celonis is a little more expensive than UiPath."
"The solution is expensive."
"Celonis is expensive. It's not for mid or low-sized enterprises because the license price is high. Overall, it's quite pricey compared to anything else that I have heard about. But the good thing is that they don't charge per user. They charge for the data model."
