What Sereno Group does

Sereno Group, operating legally as Christie's International Real Estate Sereno under At World Properties, LLC, is a private residential real estate brokerage founded in 2006 and headquartered in Los Gatos, California. The firm operates 12+ physical offices spanning Northern California submarkets including San Francisco, the Peninsula, Silicon Valley, South County, East Bay, Santa Cruz, Marin, Wine Country, Tahoe, Incline Village, Sierra Foothills, and the Central Coast, and claims to be the largest locally owned and operated independent real estate company in Northern California. Through its flagship affiliation with Christie's International Real Estate, Sereno extends its reach into a global luxury network spanning nearly 50 countries and territories on six continents, serving individual home buyers and sellers, with emphasis on luxury and high-value residential transactions.

The company runs a direct-to-consumer model in which licensed real estate agents provide in-person consultation, property search, and transaction support, supplemented by a self-service website search platform with 340 exclusive listings (50 featured on the homepage). Revenue is generated through real estate commissions split between the brokerage and individual agents on buyer and seller representation, with rates negotiated per transaction and not publicly disclosed. Adjacent services include financing option referrals through New Venture and ancillary ecosystem relationships with Proper Title, LLC, OriginPoint, A Rate Company, and Suburban Jungle, LLC, entities in which parent At World Properties holds ownership interests.

Sereno's strategic posture centers on hyperlocal community expertise, brand-led luxury positioning via Christie's, and selective inorganic expansion, evidenced by the 2020 acquisition of J Rockcliff Realtors in the East Bay. The firm employs 251-500 people, primarily licensed agents, and has built out community engagement through the Sereno 1% For Good Charitable Foundation. No proprietary technology platform, AI/ML capabilities, or venture funding are described in available source material, leaving the business model reliant on agent productivity, transaction volume, and brand-driven client acquisition.

Direct peers

• Compass: Tech-enabled national residential brokerage with a strong luxury skew and meaningful Northern California agent count. Directly competes for agents and listings and represents the principal digitally-enabled threat to Sereno's franchise.
• Engel & Völkers: International luxury real estate franchise with a presence in Northern California. Closely comparable to Christie's International Real Estate Sereno in offering global referral reach paired with localized luxury representation.
• @properties / @properties Christie's International Real Estate: Parent operating company of Sereno Group. Operates the same Christie's-affiliated luxury brokerage model in other geographies and competes for the same talent pool, brand positioning, and acquisition targets in adjacent markets.
• The Agency: Luxury-focused residential brokerage with significant California presence, including in markets overlapping with Sereno's Northern California footprint. Competes directly for high-end seller representation and celebrity/ultra-luxury listings.
• Sotheby's International Realty: Global luxury residential brokerage brand most directly comparable to Christie's International Real Estate Sereno. Both compete for high-net-worth listings and offer affiliated networks spanning dozens of countries, making Sotheby's the closest brand-side analog.

Broad incumbents

• Coldwell Banker: Large national franchise brokerage with significant Northern California agent density and a luxury sub-brand (Coldwell Banker Global Luxury). Overlaps with Sereno across the full luxury-to-mid-tier residential spectrum.
• Berkshire Hathaway HomeServices: National residential brokerage franchise with luxury positioning through its network. Competes for Sereno's high-end agents and listings and has comparable California footprint.
• eXp Realty: Cloud-based national brokerage with growing luxury and California presence. Represents a competing business model (low-overhead, agent-centric) that pressures traditional commission splits across the industry.

Regional players

• Pacific Union International: California-focused luxury residential brokerage historically centered in the Bay Area, now part of Compass. Closely comparable regional peer with similar Northern California luxury positioning prior to acquisition.
• Intero Real Estate Services: Silicon Valley-based residential brokerage with overlapping territory in the South Bay and Peninsula markets. A relevant regional peer for agent recruiting and listing competition.
