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

Hey Tzur, really interesting app. Have you considered the app branding? How the app looks and feels to users will make all the difference. Bringing the brand positioning to life is where you'd want to start.

Honest flag before the co-founder search, because it determines whether you can attract a good marketer at all: you're pre-launch with no users and no traction, asking someone to take equity on a product that hasn't proven anyone wants it. A genuinely good growth person knows that's the riskiest possible bet, so the ones who say yes are often the ones who can't get better offers. Marketing co-founders come cheap before validation and expensive after, because after, you have proof and they have less to gamble on.

The deeper issue a marketer will spot immediately: mood tracking is a brutal category. Daylio, Moodpath, How We Feel, Apple's own tools all fight for the same retention-challenged user (mood trackers have notoriously bad D30 because logging daily is a chore that fades). So the first question any strong marketer asks is "why does this win against Daylio," and "16 languages + a world map + AI insights" is a feature list, not an answer. No amount of marketing fixes a positioning gap, and a good marketer declines precisely because they know that.

What would actually attract a co-founder is a wedge. The world map (global mood patterns) is the one genuinely novel thing here, nobody else makes mood tracking feel collective/social rather than a private diary. "See how the world feels today" is a different, more shareable thing than "log your mood." That could be the whole product.

Nailing that wedge before you go looking is the highest-leverage move, and it's exactly the kind of positioning work I spend my time on, I'm part of the team building Hivemind, an AI strategy copilot that pressure-tests this. Worth running the "why us over Daylio" question through it before you pitch a co-founder: https://hivemind.myosin.xyz. Either way, lead with the wedge, not the equity, that's what makes a good marketer say yes.

i've seen numerous posts about marketing... at guestar we use automations/cron jobs and coreyhaynes marketing skills for claude. i highly recommend them. we set them up to run leadgen, outreach, blog posts, instagram posts+hooks, carousels. let me know if you need help setting this stuff up. it saves so much time and gets the organic traffic flywheel started.

Awesome build! Tackling localization (16 languages) and building out global visual data right out of the gate is no small feat for a solo dev.

Consumer app marketing is definitely a full-time job in itself. Hope you find a solid marketing co-founder to take the distribution off your plate!

Hey! Saw you're looking for marketing help for your mood app.

I’m good at content, SEO, and affiliate marketing. I have $200 I can put into ads/content.

Would you be open to 50/50 rev-share? I handle growth, you handle product.
Let's jump on a quick call?

Looks like a promising project. Having the product already built is a big advantage—now the key is finding a marketer who really believes in the idea and can help validate growth channels before scaling.

Giving away equity or revenue share for early marketing is a big step, especially when you are pre-launch.

Before committing to a co-founder, try running a few tiny, zero-budget marketing experiments on your own. For a mood tracker, look for micro-communities where people talk about burnout, habits, or mindful routines.

Instead of broad outreach, share a simple, helpful observation about tracking habits and offer early access to those who respond.

I am building Octoloops (Octoloops.com) to act as a lightweight marketing assistant for solo builders. It helps you identify these niche channels and tells you exactly what to write, so you do not have to guess.

If you want to share a bit more about how your mood tracker stands out, we can brainstorm a few easy places to start testing!

gonna push back on the framing a little — I’ve actually got a marketing background, so it’s not that I don’t know marketing. it’s more that what I built (fantasy football AI thing, still early) feels like it outran the playbooks I already know. like I know how to market a normal SaaS tool but this doesn’t fit that shape yet. anyone else hit that specific wall, not “I don’t know marketing” but “I don’t know marketing for THIS”?

I’ll add a different angle to this, since I’ve got a marketing background but I’m hitting the same wall — I think it’s less about lacking marketing knowledge and more that what I’ve built (The League Dispatch, AI-generated fantasy football content) feels bigger than the marketing frameworks I already know how to apply. I keep sensing the potential without having a clear playbook for a category that doesn’t have a direct comparison yet. Working through different strategies now, but curious if others here have felt that gap — knowing marketing, but the product outpacing the marketing you know how to do.

Bringing on a marketing co-founder before you have clear evidence of the 'burning problem' your app solves is a high-risk move. Instead of looking for a partner to distribute what you've built, try narrowing down who exactly is paying for or suffering from this specific mood-tracking data today. If you can show a consistent retention curve with a cohort of 50 users who check in daily without prodding, finding that marketing lead becomes significantly easier because you're handing them a proven engine rather than just an idea.

I'm interested in this business and would love to work with you. How can we get in touch? Would it be possible to schedule a meeting?

I feel you. I ran into the same thing. It turns out that even a great product is nothing without promotion and marketing.
