What Sit Group does

Sit Group is a family-operated residential real estate brokerage team based in Los Altos, California, operating as an affiliated team under Intero Real Estate Services (a Berkshire Hathaway HomeServices subsidiary). The firm is staffed by two licensed agents — Ross Sit and Zack Sit (mother and son) — with California Department of Real Estate licenses and combined 16+ years of experience. The team serves home buyers and sellers across the San Francisco Bay Area, with explicit emphasis on multilingual and culturally competent service in English, Mandarin, Cantonese, and Tagalog.

The company's offering consists of three products: Sellers Services (tailored listing strategies positioning sellers' interests first), Buyers Services (step-by-step guidance through purchase and documentation in a competitive market), and a Home Calculator (a custom home price analysis positioned as more accurate than third-party automated valuations). The firm operates no proprietary technology platform; the calculator appears to be a lead-generation tool embedded in the Wix-hosted website rather than a modeled valuation product. Marketing is limited to organic social media (Facebook, LinkedIn, Instagram) and the company website, with no paid acquisition or app surface.

Sit Group generates revenue solely through transaction-based real estate commissions earned on successful closings; no subscription, retainer, or recurring revenue streams exist. Pricing is not publicly disclosed, consistent with negotiated brokerage commissions. The business operates from a single office at 496 1st St #200, Los Altos, CA, and is independently owned with no external capital, subsidiaries, or parent company. As a two-agent relationship-driven boutique, the firm is structurally exposed to individual transaction concentration and Bay Area housing market cyclicality, with no disclosed deal volume or revenue figures.

Core offering

Sit Group is a residential real estate brokerage that represents home sellers and buyers across the San Francisco Bay Area, operating as a two-agent team (Ross Sit and Zack Sit) under the Intero Real Estate Services franchise in Los Altos, CA. Core services include tailored listing representation for sellers, guided buyer representation through the purchase process, and a custom home price analysis tool that factors in elements third-party valuation sites miss.

Product overview

Sit Group is a real estate services company operating as a mother-and-son team (Ross Sit and Zack Sit) under Intero Real Estate Services. The company offers a unified service portfolio consisting of three core offerings: Sellers Services (tailored listing strategies for home sellers), Buyers Services (navigating the home purchasing process), and a Home Calculator (customized home price analysis tool). The three services are designed to work together to provide comprehensive real estate transaction support, with the Home Calculator serving as a complementary tool to attract potential clients by offering free property valuations while the core buying and selling services form the primary revenue model.

Scale indicators1 record

Recent moves4 records

Expansion highlights3 records

Broad incumbents

• Sotheby's International Realty: Global luxury real estate brand with substantial Bay Area affiliate presence. Pursues a similar high-net-worth seller and premium-pricing tier but operates as a wide franchise network rather than a single local team.
• Coldwell Banker: One of the largest and longest-standing US residential real estate franchise networks with significant Bay Area agent density. Competes with Sit Group for the same buyer and seller pool but as a national volume brand rather than a boutique team.
• Keller Williams Realty: Largest US real estate franchise by agent count with active Bay Area operations. Competes broadly for residential buyer and seller representation through a high-volume, agent-centric model versus Sit Group's boutique approach.
• Berkshire Hathaway HomeServices: Parent franchise network of Intero Real Estate Services, under which Sit Group operates. Comparable as the national brand umbrella providing Sit Group with brand, MLS, compliance, and referral infrastructure, and a relevant benchmark for affiliated-agent economics.

Others

• Zillow Group: Operates Zillow, the dominant US residential real estate portal and lead-generation platform. Not a brokerage peer in the strict sense, but a critical adjacent player whose portal, valuation tools, and advertising products shape the demand, pricing, and lead-generation environment Sit Group competes in.

Emerging players

• eXp Realty: Cloud-based, agent-centric real estate brokerage with growing California agent count. Comparable as a modern, technology-led alternative to traditional franchises that recruits independent agents seeking flexible affiliation models.
• Redfin: Tech-enabled consumer-facing brokerage active in the Bay Area. Competes for the same residential buyer and seller pool with a digital-first, lower-commission model that pressures traditional boutique agents on price and convenience.

Direct peers

• SERHANT. Modern boutique brokerage built around a strong personal brand and social-media-driven lead generation. Comparable in being a small-team, brand-led operation competing against large incumbents through content, personality, and differentiated client experience rather than headcount.
• The Agency: Boutique luxury real estate brokerage with strong California presence and a brand-forward, relationship-driven agent culture. Comparable to Sit Group in its emphasis on premium service, lifestyle branding, and personalized representation rather than high-volume transactional brokerage.
• Compass: Tech-enabled national real estate brokerage headquartered in New York with deep Bay Area / San Francisco presence. Targets the same affluent buyer and seller segment in coastal California with a digitally empowered agent model, making it the closest direct competitor to a boutique Bay Area team.
