Building Cluely: The Viral AI Startup that raised $15M in 10 Weeks

What if virality wasn’t a tactic — but the entire product? In this episode, a16z General Partners Erik Torenberg and Bryan Kim sit down with Roy Lee, cofounder and CEO of Cluely, one of the most talked-about consumer AI startups of 2025. Cluely didn’t raise a mega round or drop a feature suite to get traction - it broke through by turning distribution into design: launching viral short-form videos, pushing polarizing product drops, and building in public with speed and spectacle. We cover: – Why virality is Cluely’s moat – Building a brand-native AI interface – The Gen Z founder mindset – What most startups get wrong about attention – Why creators are the new product managers – Cluely’s long-term vision for ambient AI Cluely is a glimpse at the next generation of startups, where the line between product and performance is disappearing.
