From Singapore to the World: Quantum Heaps Appoints Three Enterprise Software Veterans to Lead Global Expansion

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

SINGAPORE, Sept. 2, 2026 /PRNewswire/ -- Quantum Heaps, a Singapore-headquartered AI-native revenue technology company, today announced three senior executive appointments as it expands its global commercial operations across North America and EMEA. The company is building an alternative to the fragmented technology stack used to run B2B revenue, with its Unified Revenue Engine bringing 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 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 represent an inversion of the traditional enterprise software expansion model. Rather than a U.S. or European software company establishing Singapore operations to enter Asia, Quantum Heaps is building from its Singapore base and recruiting experienced enterprise software leaders to take the company into the world's largest technology markets.

Stevens, Cosseboom and Garner bring decades of experience building categories, opening markets and scaling enterprise software 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.

"Most software companies come to Singapore to sell into Asia. We are going the other way. Mark, Jeff and Andrew have already taken one company from start-up to a USD 1.5 billion exit, and they have chosen to do it again for a company headquartered in Singapore - Quantum Heaps," said Panwar.

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 more than two decades of enterprise software experience, including senior leadership roles at Salesforce and Vlocity, with experience building markets and strategic enterprise relationships across the UK, Nordics, Middle East and Africa.

"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.

Building Global Enterprise Software from Singapore

Founded in Singapore by Panwar, a former executive at Microsoft, Salesforce and SAP, Quantum Heaps is part of a new generation of AI-native companies seeking to build global enterprise software businesses from Asia.

The company will continue to operate from its Singapore headquarters while expanding its commercial presence across North America and EMEA.
