Launching an app is easy. Getting anyone to notice it isn’t. App stores are more crowded than ever, paid acquisition costs keep climbing, and organic discovery is nearly impossible without an existing audience. For early-stage app companies chasing their first 10,000 downloads, and for mature app companies stuck on a growth plateau, the fastest, most credible path to traction increasingly runs through people, not ads: athletes, celebrities, and influencers whose audiences already trust them.
That’s the gap CelebExperts was built to close. If you’re researching how to hire an influencer marketing agency for app growth, book a celebrity to promote an app, or find an app marketing agency that drives real downloads and trials, here’s how the process works and why CelebExperts has built a name for itself in this category.
Why App Companies Need More Than Paid Ads
Paid user acquisition, App Store ads, social ads, programmatic, still has a role, but cost per install has risen sharply across nearly every category, and paid traffic alone rarely builds trust fast enough to turn a download into an active, retained user. That’s the real problem app companies are solving for. Not just downloads, but trials that convert and users who actually stick around.
Celebrity, athlete, and influencer partnerships solve a different part of the funnel than ads do. A trusted voice recommending your app carries more weight than a banner, because the audience already has a relationship with that person. Influencers and athletes can show the app in real use, onboarding, a key feature, a specific use case, in a way that feels native instead of promotional. And a single well-placed post can outperform weeks of paid spend in both reach and completion rate, especially paired with usage rights that let the brand repurpose the content across its own paid channels.
That’s what’s behind searches like “celebrity app promotion agency,” “influencer marketing for app downloads,” and “how to get a celebrity to promote my app.” Understanding what a specialized agency actually does before reaching out saves real time, money, and risk.

What to Define Before Reaching Out
Before contacting an agency, it helps to know your growth stage and objective, chasing initial download volume for a funding milestone, driving free-trial-to-paid conversion, or scaling a channel that’s already proven. Target audience matters too, consumer, B2B, fitness, fintech, gaming, food and lifestyle, and productivity all call for different talent and different platforms.
Budget shapes the shortlist: campaigns for app growth generally scale from a few thousand dollars for a single creator post to well into six figures for a multi-tier, always-on program. Talent tier matters as well, macro-influencers and athletes deliver reach and credibility, micro and niche creators typically deliver the strongest engagement and direct response, and most effective programs blend both. Last thing to settle up front: usage rights and whitelisting, will the content run in paid social, on your site, or in investor materials? That changes contract terms significantly.
Because all of this shapes cost and the right talent list, most experienced growth teams skip negotiating directly with an athlete’s agent or an influencer’s management. They work through a specialized agency that already has live relationships and a track record of turning partnerships into measurable download and trial numbers.
How CelebExperts Helps App Companies Get Traction
Founded in 2008 by longtime sports agent and marketing strategist Evan Morgenstein, CelebExperts was built around two things: booking celebrities, athletes, and influencers who deliver real impact, and consulting brands on how to get the most out of every campaign. That dual focus fits app companies well, where the goal isn’t just visibility, it’s measurable downloads, trials, and retained users.
Influencer programs built for app funnels. CelebExperts doesn’t book influencers in isolation, it builds tiered creator programs meant to compound over time instead of resetting with every campaign: macro-influencers for awareness and download volume, mid-tier creators for trial sign-ups through authentic demos, micro-influencers for the highest engagement within specific niche communities like fitness, finance, gaming, or parenting.
Celebrity and athlete endorsements. For companies with budget for a bigger splash, a funding announcement, a major feature launch, a Super Bowl-adjacent moment, CelebExperts negotiates deals ranging from a single social post to a full spokesperson relationship. Because the agency represents the brand and not the talent, negotiations are structured to protect the client’s budget instead of paying inflated “brand tax” pricing.
NIL and college athlete marketing. Through its affiliated agency Renegade Talent MGMT, CelebExperts has deep access to the NIL market, a fast-growing, cost-efficient way to reach Gen Z and college-age users through athletes who are already trusted voices on campus and online.
Whitelisting and paid social amplification. Beyond organic posts, CelebExperts structures campaigns with whitelisting rights so companies can run influencer- or athlete-created content through their own paid channels, extending reach past the creator’s organic audience and giving performance teams new, high-trust creative to test.
Full-funnel strategy, not one-off bookings. CelebExperts positions itself as a growth partner, selecting, vetting, briefing, and managing talent inside a full-funnel program. Particularly valuable for early-stage companies that don’t have in-house influencer expertise yet and need a strategic partner, not just a booking desk.
Rapid-turnaround activations. App companies often need to move fast, a trending moment, a competitor stumble, a viral opportunity. CelebExperts has a track record of moving from negotiation to contracting to filming within days, which matters enormously when timing determines whether a campaign lands.
Category expertise beyond traditional influencers. Professional athletes, NIL stars, celebrity chefs, reality TV personalities, pop culture figures, motivational speakers. A fintech app might do better with a respected financial expert or athlete-entrepreneur than a lifestyle influencer, and that broader access supports precise matching.
Why Both Early-Stage and Mature App Companies Benefit
Early-stage companies typically need download volume and credibility fast, often ahead of a funding round or public launch. CelebExperts’ ability to move quickly, work within lean budgets, and lean on micro and mid-tier influencers for cost-efficient reach makes it a practical fit for startups that can’t afford a celebrity spokesperson yet but need more than a paid ad budget alone can deliver.
Mature app companies typically need to break through a plateau, re-engage lapsed users, or support a major launch with outsized visibility. Access to athletes, celebrities, and larger endorsement deals, combined with whitelisting rights that feed a mature paid social engine, offers a way to keep acquisition costs efficient even as easier growth channels get harder to scale.
Either way, the consulting-first approach means campaigns get built around measurable outcomes, downloads, trial starts, conversion, retention, rather than vanity metrics like follower count.
Why CelebExperts Stands Out
There’s no shortage of agencies offering “celebrity marketing” or “influencer marketing” services. A few things set CelebExperts apart for app companies specifically: buyer-side representation, since the agency works exclusively for the brand and not the talent, so recommendations are unbiased and negotiations protect the client’s budget and terms. Decades of sports and celebrity relationships, since founder Evan Morgenstein built his career representing Olympic medalists and professional athletes before founding CelebExperts, giving direct-line relationships rather than layers of intermediaries. A genuinely broad talent network spanning athletes, NIL stars, celebrity chefs, reality personalities, and niche digital creators, matching a company to the right voice instead of defaulting to whoever’s easiest to book. Speed, with a demonstrated ability to negotiate, contract, and produce content in as little as a week when a brand needs to capitalize on a timely opportunity. And results over vanity metrics, having built full-funnel programs that scaled brands to millions in revenue and over a million orders.
Getting Started
If your app company is trying to generate real traction, not just impressions but downloads, trials, and retained users, the smartest next step is a conversation with a team that already understands how to translate celebrity, athlete, and influencer trust into app growth. Whether you’re an early-stage company needing your first wave of credible downloads or a mature app looking to reignite growth ahead of a major launch, CelebExperts can help build the right mix of talent, strategy, and execution to move the metrics that actually matter.
App growth windows close fast, and the best talent, from niche micro-influencers to in-demand athletes, books up quickly around major launches, sporting events, and cultural moments. Companies that start the conversation early have significantly more options, better pricing, and more time to build a campaign that actually converts.
