- Connected, optimised resources – better utilisation of rooms, desks, and shared services to optimise workspace usage

- Sustainable, efficient outcomes – analytics that drive energy efficiency and smarter space planning.
Aries Global is a rapidly scaling software group focused on accelerating and transforming founder-led B2B software companies through world-class operating resources and a proprietary AI platform. Aries is comprised of a senior team with a track record of excellence at category-leading companies such as Snowflake, Palantir, Goldman Sachs and Google.
“Add-On Products is everything we look for in a category-defining software company: founder-built, customer-trusted, and embedded in a mission-critical workflow,” said Michael Mitterlehner, Co-Founder & CEO of Aries Global. “We’re excited to help the team scale what already works, while bringing Aries’ AI platform, marketplace access, and go-to-market expertise to help customers unlock faster ROI and value.”
“Hybrid work is the operating reality for global enterprises. Add-On Products has proven its value in that shift. Together, we’ll extend that impact, fuel growth, and shape the next wave of innovation,” added Thibaut Ceyrolle, Co-Founder & CRO at Aries Global.
Peer Astrup, CEO of Add-On Products and Add-On Group, said: “Aries gives us the operational strength to scale faster without losing focus on what matters most: customer experience and value. We’re turning workspace management from an administrative afterthought into a lever for cost, culture, and carbon efficiency.”
