The Operator's Operator
The resume reads like a greatest-hits compilation of enterprise software's last two decades: Electronic Data Systems, Stellent, Oracle, Salesforce, Act-On, UserTesting, Alteryx. But what makes Andy MacMillan interesting isn't the list - it's that every stop was a transformation story, and he kept choosing companies mid-turn rather than ones that were already humming.
He started as a Java developer in Detroit, building enterprise web applications for General Motors at EDS in the early days of the web. That detail matters. Most enterprise software CEOs arrive via consulting or finance. MacMillan arrived through the actual code - the kind of person who understands why a data pipeline breaks, not just what it costs when it does.
"Great companies are built on foundational pillars of culture and customer-centricity - I'm delighted to join such a company."
Andy MacMillan, on joining Alteryx as CEO, December 2024The Edinburgh MBA was a detour that became a defining thread. A Midwesterner who earned an international MBA in Scotland doesn't just add a credential - he adds a network, a perspective, and, eventually, a formal appointment as a Trade and Investment Envoy for the Scottish Government. In 2022, the Scottish government named MacMillan as one of two California-based envoys tasked with building trade and investment connections between Scotland and American high-growth tech markets. He represents Scotland's interests at events like Tartan Week from his Bay Area base - while simultaneously running a major enterprise software company.
At Oracle he managed a $1B+ product line in the Fusion Middleware Group by his early 30s, working under Thomas Kurian. That's where he learned how large organizations drive consensus without top-down control - a lesson that would define his leadership philosophy at every company that followed. At Salesforce he served as Product Group COO and led Data.com, absorbing what customer-centricity looks like when it's baked into a company's DNA rather than bolted on as a marketing message.
Act-On Software was his first CEO role, and he took a marketing automation company from niche player to Gartner Visionary. Then UserTesting - which he joined in 2018 and grew from $40 million to over $100 million ARR, accelerating annual growth from 22% to 35% through deliberate pipeline focus. His diagnosis at UserTesting was straightforward: the product had genuine product-market fit (every customer told him the same story), so the constraint was growth infrastructure, not product quality. He fixed the constraint.
Now at Alteryx - backed by Clearlake Capital and Insight Partners since the company went private in 2023 - he's operating at a different scale entirely. The $1 billion ARR milestone came in early 2026. The community has grown to 750,000+ members. The platform now automates 380 million workflows annually. His mandate: make Alteryx the governed analytics layer that enterprises need before they can actually trust AI at scale.
