When Pegasystems began building its cloud business, the economics were hardly what investors would expect from a mature software company. Cloud gross margin was below 30%, recalls CFO and COO Ken Stillwell. The destination was roughly 80%. Getting there, however, required accepting that the path would not be straight.

At one point, Pega deliberately stepped backward on margin to make investments needed to scale the operation. “It put us probably off our margin targets by a year or two,” Stillwell says. “But it was a necessary investment for us to continue to scale.” Today, he says, cloud gross margin is approximately 80%.

That willingness to examine economics without losing sight of the customer runs through Stillwell’s thinking about Pega today. Growth comes largely from expanding existing customer relationships, making adoption—and the transaction volumes that follow—an important early signal. Stillwell looks for patterns across verticals, regions and customer cohorts to understand where expansion is taking hold. 1218 Ken Stillwell

AI introduces another economic puzzle. Pega chose not to build its model around maximizing token consumption. Stillwell argues that customers should use AI where it actually fits the work, selecting the appropriate model—or no AI at all—rather than treating consumption as the objective.

It is an approach consistent with the Rule of 40 discipline Stillwell helped spread throughout Pega: growth matters, but so do the economics behind it.

For the coming year, his priority is less about predicting every turn than preparing Pega to absorb them: staying agile, managing change and, as Stillwell puts it, remaining “calm and process focused” when the seas get rough.
