The trend of onboarding celebrities as co-founders makes perfect sense; they bring instant distribution, credibility, and built-in audience. But there's a fundamental mismatch in how these deals get done versus how they should get done.

Being co-founders is like marriage. You'll work together for the next 5-10 years. You'll make critical decisions together. You'll be tied to each other through good times and bad. Yet most founders spend more time choosing their morning coffee than vetting their celebrity partner.

This week, I'm breaking down the dating playbook: how to test celebrity partnerships before committing equity, why most fail, and the structures that protect both parties when things don't work out.

Get access to it here. Spot a brand I missed or a mistake? Let me know, and I will fix it.

Picture this: A founder gets a meeting with a celebrity who has 20 million followers. They get starstruck. They think, "If just 5% of those followers become customers, we'll be multi-millionaires." They rush into an equity deal, giving away 20% of the company.

The celebrity posts twice. Sales barely move. Now the founders are frustrated because they gave away a fifth of their company. The celebrity isn't motivated to keep posting. Everyone's stuck in a bad marriage with no prenup.

I see this pattern weekly. Founders fall in love with follower counts the way people fall for physical attraction. They see 20 million followers and lose all rational thought. They skip the courtship and jump straight to marriage.

But follower count is just surface-level attraction. It tells you nothing about whether this partnership will actually work.

Think about what you're really signing up for: This person will be your business partner for the next decade. They'll represent your brand. They'll influence major decisions. They'll own a significant chunk of your company forever.

Would you marry someone after one date just because they're attractive? Then why would you give them 20% of your company after one meeting just because they have followers?

Here's what founders miss: Most celebrities already have tens of millions of dollars. They're not doing this for the money. Their motivations could be completely different from yours.

You want revenue growth and a successful exit. They might want creative control, legacy building, or just something interesting to talk about on podcasts. If you don't understand what actually drives them, you'll never create a successful partnership.

Before you even discuss equity, you need to understand:

You don't figure this out in one 20-minute Zoom call. You need multiple conversations, shared experiences, maybe even working on a small project together. You have to genuinely get to know each other as people, not just as business opportunities.

And beyond the personality match, you also need to discover if they can move your product. Having millions of followers means nothing if they can't convert them into customers for your specific product. 

Ask for data from their previous partnerships. What were the actual conversion rates? How did those products perform? If they have other brands they co-founded in market, study those results.

But here's the critical part: Just because they sold someone else's skincare doesn't mean they can sell your supplements. Their audience might buy fashion from them but not food. They might trust them for beauty but not beverages. You need to test your specific combination. 

This might feel contradictory, but start with a paid partnership. Yes, it costs money, exactly what you're trying to avoid with an equity deal. But it's infinitely cheaper than giving away 20% to the wrong partner.

If the long-term goal is an equity deal, celebrities are typically open to lowering their rates as part of the evaluation process. Or structure it as an affiliate or revenue share to align incentives. If they truly believe in the mission, they may promote organically to be part of something meaningful and demonstrate they can move the product.

Remember: You're not just pitching them. They should be pitching you too. If they're not willing to prove they can deliver value before taking equity, that tells you everything you need to know.

If you want to test on a deeper level, consider co-branded products. It's more involved than a simple paid post but less permanent than equity.

We're, for example, working with UpPaint, a company that upcycles unused paint into premium products. They wanted to bring DIY creators on as equity partners to spread their sustainability mission. But instead of rushing into equity partnerships, we developed a two-step process.

First, we create co-branded paint lines. Each creator gets custom colors based on their aesthetic. UpPaint handles manufacturing and fulfillment. Creators focus on content and promotion. Revenue share structure means they earn more when they sell more.

This works because it feels ownable to the creator. Instead of "buy this paint," they say "get my signature color collection." It's authentic, entrepreneurial, and testable.

We run the co-branded lines for several months, tracking everything. Sales, engagement, creator involvement, audience response. Then we graduate the best-performing creators to equity partnerships. But only after they've proven they can actually move product AND work well with the team. Remember, you need to work with these celebrities for the next couple of years, so make sure there is also a personal connection, which is often even more important than numbers alone.

Even celebrities are testing before launching their own brands. Take Sydney Sweeney, she's just launched a lingerie brand. But she's been collecting data points for years.

Her 2024 collaboration with Frankies Bikinis sold out instantly. That wasn't just a partnership; it was market research. She tested whether her audience would buy swimwear from her. They did. Now she has data, not just hope.

When she launched her lingerie brand, she wasn't guessing. She knew exactly what her audience wanted, at what price points, in what styles. Smart celebrities test the waters before diving in.

An alternative to paid partnerships or co-branded lines is starting with a smaller equity deal. Instead of making someone a 20% co-founder immediately, start with 0,5-1% over six months.

Set specific deliverables. Track their actual involvement. See if you can work together effectively. Determine if this is someone you want as a partner for the next 5-10 years. Most importantly, verify they can actually move the product and can add value beyond their initial posts.

This approach feels more natural to their audience too. If a celebrity promotes a brand for six months then announces they're a co-founder, it feels authentic. When someone who's never mentioned hot sauce suddenly launches as co-founder of a hot sauce brand, everyone sees through it.

Even marriages with years of dating sometimes fail. Celebrity-founder partnerships need prenups too.

Always Include Vesting: Never give 20% upfront. Four-year vesting with a one-year cliff. If it doesn't work out, you keep your equity.

Define Clear Deliverables: Number of posts, retail appearances, investor calls, content creation. Make expectations crystal clear. Both sides need to know exactly what they're signing up for.

Build in Clawbacks: If deliverables aren't met, you can recoup equity. This protects you from celebrities who lose interest after the announcement.

Set Performance Milestones: Tie additional equity to actual business results, not just activity. If they can't move product, why should they own more of the company?

These structures protect the startup if the dating phase looks promising but the marriage doesn't work out. They're not punitive, they're practical safeguards for both parties.

The biggest mistake founders make is treating celebrity partnerships like lottery tickets instead of marriages. They see follower counts and lose all rationality.

But follower count is just attraction. You need compatibility, shared values, aligned incentives, and proven ability to work together. That only comes from dating before marriage.

Test with paid partnerships. Try co-branded products. Start with small equity deals. Include vesting and clawbacks. Make them prove they can move your specific product, not just any product.

Most importantly, remember this is a two-way street. They should be proving themselves to you just as much as you're pitching them. If they're not willing to test the relationship first, they're not the right partner.

I just started creating content on X. Would love to connect there.

This week, I'm joined by Genevieve Gilbreath, General Partner at Springdale Ventures, an early-stage consumer fund that has backed some of the most successful celebrity and creator-founded brands in the market, including Feastables by MrBeast, Goodles with Gal Gadot, Khloé Kardashian's Khloud, and The Absorption Company with Nikki Reed and Ian Somerhalder.

Genevieve breaks down why Springdale is not a dedicated celebrity fund and why that makes her lens on celebrity brands more credible than most, what she actually looks for before writing a check, why cap table structure can kill a deal before it starts, and the most common reasons she passes on celebrity brands despite her portfolio suggesting otherwise.
