Mark Stevens, Jeff Cosseboom and Andrew Garner join leadership team to build global marketing and North American and EMEA operations

NEW YORK, Sept. 1, 2026 /PRNewswire/ — Quantum Heaps today announced three senior executive appointments as the company expands its global commercial operations and brings its AI-native Unified Revenue Engine to the global enterprise market.

Quantum Heaps has built an alternative to the fragmented technology stack used to run B2B revenue. Its Unified Revenue Engine brings CRM, prospecting, conversation intelligence, forecasting, enablement, analytics and commissions together on a single platform and common data model. Powered by Agent Q, the platform applies AI across the revenue lifecycle to identify signals, coordinate workflows and execute work – helping companies increase productivity, improve predictability and accelerate revenue growth.

Mark Stevens joins as Chief Marketing Officer, Jeff Cosseboom as President, North America, and Andrew Garner as President, EMEA. The three executives will lead global marketing and the company’s North American and European operations as Quantum Heaps moves from product innovation to commercial scale. All three will report to Harsh Panwar, Founder & Chief Executive Officer of Quantum Heaps.

The appointments bring together enterprise software veterans with decades of experience building categories, opening markets and scaling technology businesses. All three also share experience at Vlocity, the industry cloud pioneer acquired by Salesforce in 2020 in a transaction valued at approximately $1.5 billion.

“We’ve built the product. Now we are building the commercial organization to take it to market globally,” said Panwar. “Mark, Jeff and Andrew have built categories, opened markets and scaled enterprise software businesses before. They bring the experience we need for Quantum Heaps’ next phase of growth.”

Mark Stevens, Chief Marketing Officer

Mark Stevens will lead Quantum Heaps’ global marketing, category development, positioning and go-to-market strategy. He brings more than 25 years of enterprise software experience across Amperity, Automation Anywhere, Salesforce, Vlocity, Oracle and Siebel, spanning marketing, business value, industry strategy and customer transformation.

“RevTech has an architectural problem, and the answer isn’t another AI tool bolted onto an already fragmented stack,” said Stevens. “Quantum Heaps is rethinking the architecture itself – unifying revenue execution around a single, AI-native platform designed to increase productivity, improve predictability and accelerate revenue growth.“

Jeff Cosseboom, President, North America

Jeff Cosseboom will lead Quantum Heaps’ commercial operations and expansion across North America. He brings more than three decades of enterprise software sales leadership, including senior roles at C3 AI, Salesforce/Vlocity, SAP and Siebel/Oracle.

“Revenue organizations have spent years adding specialized tools to solve individual problems, creating more integrations, data silos and complexity,” said Cosseboom. “Quantum Heaps changes that equation by bringing revenue execution together on one AI-native platform. That creates a significant opportunity in the North American enterprise market.”

Andrew Garner, President, EMEA

Andrew Garner will lead Quantum Heaps’ expansion across Europe, the Middle East and Africa. He brings extensive enterprise software experience, including senior leadership within Vlocity and the Salesforce ecosystem, with a track record of building markets and strategic enterprise relationships across the region.

“European enterprises are moving quickly on AI, but they are also becoming more disciplined about where it creates measurable business value,” said Garner. “Quantum Heaps starts from a different premise: unify the revenue environment and make AI native to how the organization operates.”

The appointments support Quantum Heaps’ expansion of its Unified Revenue Engine, which brings CRM, forecasting, conversation intelligence, enablement, commissions and other revenue workflows together on a common data model. Powered by Agent Q, the platform is designed to move beyond analyzing revenue activity to identifying signals and executing work across the revenue lifecycle.
