Arkestro Momentum Drives Leadership Growth and Appoints Industry Powerhouse Veterans

Two enterprise SaaS operators bring 50 years of combined experience to Arkestro's leadership team as Ben Leiken transitions from CTO to become the company's first Chief Product Officer

SAN FRANCISCO, Aug. 6, 2026 /PRNewswire/ -- Arkestro, the leading predictive procurement platform accelerating enterprise scale, today announced the appointments of Tom Aitchison as President and Chief Operating Officer and Ron Rasmussen as Chief Technology Officer.

"Arkestro is entering an exciting new chapter of growth, and building the right leadership team is essential to achieving our vision for predictive procurement," said Rob DeSantis, CEO and Co-Founder of Arkestro. "Tom's operational leadership and Ron's technology expertise will help us scale every part of the business, from operations and customer success to product innovation and engineering, and continue defining the future of predictive procurement."

Aitchison, who previously served as one of Arkestro's strategic advisors, has worked alongside the company's leadership on go-to-market strategy, messaging and the operational systems needed to support its current phase of growth. Across decades of experience scaling enterprise software companies, he has held executive positions at Coupa, Swrve, and Introhive, and helped lead multiple successful acquisitions along with Coupa's NASDAQ IPO.

"Supply networks keep getting more complex, yet executives want their procurement teams to move faster, uncover more savings, and increase visibility into every buying decision. The pressure isn't easing, and traditional software can't keep up," said Aitchison. "Arkestro is one of the few platforms already built for the reality of the next five years, as procurement becomes the deciding function in how enterprises compete on cost and supply chain resilience. I'm looking forward to helping Arkestro continue scaling, so the teams using this platform become the ones setting the standard the rest of the market has to catch up to."

Rasmussen joins Arkestro after serving as co-founder and Chief Technology Officer of Latitude 39, an incentive compensation management platform for small and midsize businesses. His career spans more than 25 years of enterprise SaaS technology leadership, with over a decade as CTO of Xactly, a Vista Equity portfolio company, and senior positions at Quova and KnowNow.

Rasmussen will work closely with Ben Leiken, who is stepping into the role of Chief Product Officer. As product and engineering at Arkestro have each grown to require full-time executive focus, the addition of a CPO gives product vision its own dedicated leadership alongside Rasmussen's engineering execution.

"I've spent 25 years building enterprise systems, and this is the first time I've seen procurement technology that genuinely changes how a category manager makes buying decisions. Ben and the team have built something truly rare, a predictive intelligence solution that's actually doing work inside of the platform, not just decorating a dashboard. There's a lot more we can build on top of that, and it's why I joined," said Rasmussen.

This expansion of Arkestro's leadership comes during a period of significant business momentum for the company. Year to date, total customer spend through Arkestro's platform has more than tripled compared with the same period last year. As global demand for AI-powered procurement continues rising, Aitchison and Rasmussen will help Arkestro to parallel its growth, scaling business operations and core platform capabilities.
