Co-Founder & CTO

About the role

About the Role A pre-seed AI creative platform — connecting creators who produce video ads with brands — is seeking an exceptional technical leader to join as an equal Co-Founder and CTO . The company is backed by experienced founders and operators with deep roots in consumer tech, gaming, and venture, and has already achieved meaningful early traction with thousands of creators producing content for recognizable brand partners. The mission: build individualized AI that understands human taste and enables a true creative democracy. The flywheel is already running — and the incoming technical co-founder will decide how it evolves. This is not a conventional CTO hire . You will not be executing someone else's roadmap. Several of the most consequential architectural and product decisions are deliberately still open, waiting for the right person to own them. You will have real authority, meaningful equity, and genuine co-founder standing from day one.
