About Beacons AI

Beacons is building the easiest way for creators to build a website their fans will love — centralizing a creator's online brand presence, connecting them with audiences and partners, and helping them understand and grow their businesses.

Why Candidates Should Join

• Massive scale: Products already serve millions of page views per day and are scaling toward billions.
• Genuinely AI-native team: AI is the default way the team scopes, builds, and ships — not a bolt-on or a productivity hack.
