Solo-built a mood-tracking app, looking for a marketing co-founder

I built Happiness Index - a mood tracking app - completely solo. It's fully functional: daily mood logging with photos, a world map showing global mood patterns, AI-generated insights, 16 languages supported.

I'm a builder, not a marketer, and I don't have the bandwidth or budget to run organic growth alone. Looking for someone who's genuinely good at marketing/growth to join as a co-founder with meaningful equity or revenue share.

Currently pre-launch on app stores. Happy to share a demo or more details.

DM me if this sounds interesting.
