Before Tiffany Sieve led global marketing at Xactly, she spent three years selling on 100% commission. The experience left her with a durable idea: marketing earns its place when it helps somebody sell.

Xactly’s CEO built his career by moving closer to the work - from Wall Street deal rooms to product teams, cloud software, and a leadership philosophy rooted in curiosity, data, and the willingness to rethink.

From punch cards to AI, the Canadian software marketer has kept returning to the same durable work: earn attention, create genuine interest and help sales close. His career is a lesson in changing the tools without losing the plot.
