Foolish Take

While both C3.ai and UiPath operate in the artificial intelligence sector, the latter sports far greater revenue, and is enjoying a trend of consistent year-over-year sales growth, while the former is seeing a year-over-year decline. This points to the broader appeal of UiPath's AI solutions compared to C3.ai's offerings.

But there's another reason for C3.ai's plunging sales. The company's founder and CEO, Thomas Siebel, resigned from the position in 2025 due to health issues. Under his leadership, C3.ai was doing well, as evidenced by its far higher quarterly revenue totals from 2024 to late-2025. He returned to the CEO spot in June, but in the interim, the company's business fell apart.

Siebel's return seems to be improving the business. In C3.ai's fiscal first quarter, ended July 31, the company's customer bookings increased 73% quarter over quarter. This bodes well for future revenue growth.

Meanwhile, UiPath's sales trajectory appears to be slowing down. The company's revenue of $410.3 million in its fiscal Q2, ended July 31, represented about a 13% year-over-year increase. However, management projects Q3 sales to be in the range of $440 million to $445 million, which is around 8% year-over-year growth, a sharp drop from Q2.
