Zillow Group is a digital real estate marketplace that connects home buyers, sellers, renters, and real estate professionals through its portfolio of brands including Zillow, Trulia, and StreetEasy. It generates revenue primarily through real estate agent advertising and lead generation services (~60% of revenue), home flipping operations through its Zillow Offers segment (~30%), and mortgage origination and title services.

Zillow Group is a digital real estate marketplace that connects home buyers, sellers, renters, and real estate professionals through its platform. It generates revenue primarily from real estate agent advertising and services (its IMT segment), home flipping operations (its Homes segment), and mortgage origination services.

Autohome operates China's leading online automotive content and transaction platform, connecting car buyers with automakers and dealers. It generates revenue primarily through media services — automaker advertising and regional marketing campaigns — and leads generation services — dealer subscriptions and advertising — with additional income from its Autohome Mall transaction platform and commissions on auto-financing and insurance products.

Shutterstock operates a global marketplace for stock photography, video footage, and music content used by businesses and creators. It generates revenue primarily through subscription plans — where customers pay monthly or annual fees for content downloads — and through on-demand purchases from its extensive digital library. The company's key advantage is its massive, curated content library of over 400 million images and 30 million video clips, which creates network effects as more contributors attract more customers.
Groupon operates an online marketplace that connects consumers with local merchants offering deals and discounts. It makes money primarily by taking a commission — typically 30-50% — on each deal sold through its platform, with additional revenue from direct sales of first-party inventory. The company's key advantage is its established network of millions of users and thousands of local merchants, creating a two-sided marketplace that's difficult for new entrants to replicate at scale.

Both have compounded well over 10 years (ATHM: +11.4%, GRPN: -86.8%), confirming both are viable long-term holds — but the lower-volatility option typically results in less emotional selling during corrections.

ATHM, SSTK pay a dividend while ZG, Z, GRPN do not, making them suitable for different income and tax situations.
