Synergy by SilverDoor launches in London, Dublin, Silicon Valley and New York
SilverDoor, the world’s leading independent corporate accommodation agency, has today launched Synergy by SilverDoor: its directly managed portfolio of premium serviced apartments, designed to deliver consistent, hospitality-led extended stays for corporate travellers, assignees and project teams.
Synergy by SilverDoor was created following the merger of SilverDoor and Synergy Global Housing in August 2025, bringing together Synergy Global Housing’s direct-lease expertise and branded portfolio with SilverDoor’s agency infrastructure and technology platform. It is led by Leslie O’Brien, Chief Product Officer and CEO Stuart Winstone.
Synergy by SilverDoor launches today with flagship properties in London, Dublin, Silicon Valley, and New York. The brand is actively expanding with targeted growth planned in major business centres across the US and Europe.
Every Synergy by SilverDoor apartment is leased and operated directly by SilverDoor. Design standards, operations, and the guest experience are maintained to a single in-house benchmark – from arrival preparation and move-in readiness to dedicated in-stay support and departure services. For travel managers and mobility teams, that means a product with transparent service standards, safety and compliance alignment.
Stuart Winstone, CEO of SilverDoor, said:
“We’ve been advising operators on how to refine their product for the corporate market since 2000; we had the opportunity to apply everything we have collectively learned about what a great corporate stay requires, and to build something from the inside out.
“Synergy by SilverDoor is the result of decades of experience helping clients and travellers navigate the extended-stay market. We’re already trusted by the world’s leading companies; extending that trust from enquiry to full guest experience is a significant step in our growth, and one we are excited to deliver on.”
Synergy by SilverDoor complements SilverDoor’s agency model by offering a directly controlled inventory tier. When clients require additional control, dedicated housing solutions, or accommodation in high-demand markets, Synergy by SilverDoor steps in: taking leases, individual units, or entire buildings to deliver exactly what the programme requires.
Clients benefit from the breadth of an independent agency and the assurance of a directly operated product, through one single relationship.
