SightLine — Celebrity Relationship & Sighting Timeline

A fan-curated timeline that turns 'who is X dating?' into a clean, sourced profile — every sighting, rumor, and confirmation on a single scroll, with a community trust score so fans can tell noise from news.

Target user

Olivia Rodrigo and pop-culture fans tracking celebrity romances

Features
  • Auto-built partner profile cards (career, age, prior public sightings, social handles) the moment a name trends
  • Community-vetted rumor vs. confirmed-news split with sourced links
  • Personal 'track this celeb' alerts that ping when a tracked star is spotted with someone new
  • Side-by-side relationship history view across exes and rumored flings
Why now

The Olivia Rodrigo / Julian Croonenberghs sighting cycle shows fans don't just want a headline — they want a fast, contextualized dossier on the new person, and there's no fan-first timeline product serving that.

Demand

Whitespace

Multiple entrenched incumbents already serve this exact use case (WhosDatedWho, Dating History Hub, MyPassionList, faces.news), making differentiation hard and the niche clearly contested.WhosDatingWho - Celebrity Relationship History & Dating TimelinesDating History Hub - Verified Timelines80 Best Celebrity Gossip Blogs

Monetization
4/10

Ad-supported models work only at scale (whosdatedwho reaches 1.69M–3.2M visits/mo); subscriptions unlikely in commodity gossip, and trust-score premium has weak historical WTP evidence.whosdatedwho.com Traffic Analytics & RankingWebsite Traffic Checker - Similarweb

Longevity
6/10

Celebrity-romance interest is evergreen and content compounds as an archive, but traffic spikes are cyclical (driven by sightings) and any single celebrity archive decays once they leave the spotlight.Best Entertainment News Sites & BlogsBest Fandom Alternatives

Feasibility
5/10

Core tech is straightforward, but sourcing/verifying sightings, moderating fan submissions, and legal exposure over celebrity photos/defamation create meaningful ongoing ops cost.Celebrity Relationship Timeline Tracker Guide
