TL;DR
Partnier is the evolution of Keymailer. The same trusted network that connected developers with influencers, now expanded into a complete publishing ecosystem. Under one brand, we’ve unified influencer outreach, press engagement, playtesting, paid collaborations, event promotion, and creative support. Developers, publishers, and agencies can now use Partnier to plan, run, and track campaigns across every major channel, with local teams supporting them in six languages worldwide.

How We Evolved from Keymailer to Partnier
When we launched as Keymailer, our goal was simple: help developers get their games into the hands of the right creators. It was a new idea at the time. A trusted way to connect studios with influencers for authentic, organic coverage. That focus built one of the largest verified creator networks in the world, reaching billions of followers across YouTube and Twitch.
But as our clients’ needs grew, so did we. Studios wanted to reach press and journalists, run playtests, manage paid collaborations, and tie everything together across multiple channels and languages.
That journey led us to Partnier.
One Brand, Multiple Portals
Partnier is the central hub, the platform where publishers, developers, and agencies log in to manage every type of campaign. From here, they can access all the connected portals that power the broader ecosystem:
- Keymailer: the influencer-facing platform where influencers discover, request, and cover games.
- JustInfluencers: Run paid collaborations, sponsorships, Bid Battles, and Feats.gg micro-challenges, fully managed by our campaign team.
- Game.Press: the press portal, designed for verified journalists and outlets to receive pitches and review codes. (It’s not a press release distribution network, it’s for meaningful one-to-one engagement between studios and journalists.)
- Playtester.net: the home of our playtesting CRM, where developers manage playtest recruitment, communication, and analysis.
Together, these portals connect every part of the publishing process. From early testing to long-term coverage.
Expanding the Publishing Spectrum
Over the past few years, we’ve grown beyond our roots in organic influencer outreach.
Event Promo’s have become one of the most popular services. We now run two or more themed event activations every month, timed with Steam festivals, seasonal sales, and platform showcases.
Giftingbot, our free Discord-native code distribution tool makes it easy to share gaming items with your communities where they hang out, Discord.
We’ve also launched Creator Connect. A program that introduces press and influencers to studios during in-person events, helping campaigns bridge the gap between digital and physical.
And in 2025, we unveiled Nova Game Expo. An immersive, 3D virtual event space that combines live announcements, interactive kiosks, and AI-powered NPC hosts who can speak any language. It’s a global showcase designed for the new era of digital events.
The Power of Integration
While each portal serves a different audience, they all connect through the Partnier dashboard, where publishers and promoters can plan and monitor their activity across channels.
Partnier’s analytics and intelligence layer gives clients real-time visibility into influencer content, press coverage, and community activity. It tracks over 500,000 gaming channels globally, providing speech-to-text transcription, sentiment analysis, and compliance monitoring to ensure transparency and performance across every campaign.
Global by Design
We now operate across three continents, with teams fluent in English, Japanese, Chinese, Spanish, Brazilian Portuguese, and German. That multilingual, multicultural capability allows us to support publishers and agencies running campaigns that target global audiences, from Asia to Europe to the Americas.
Whether you’re coordinating coverage in Tokyo, running a regional press campaign in Spanish, or managing influencer activations across Latin America, our teams can help you engage the right voices in the right regions.
Built for Every Stage of a Game’s Life
Partnier supports your publishing journey from the moment a game is first announced:
- Pre-launch: Playtests, community seeding, and early access programs.
- Launch: Influencer activations, press reviews, paid campaigns, and event promos.
- Post-launch: Long-term creator programs, live-service updates, and catalogue marketing.
Each stage can be self-served, assisted by an account manager, or fully managed by our in-house campaign team.
And with our growing creative studio, we can now produce video, design, and social content assets to complement every activation.
The Same Mission, a Bigger Vision
From Keymailer to Partnier, our mission hasn’t changed, only the scale has. We’re still here to help great games find their audiences, offering the same trusted relationships, low barriers to entry, and exceptional service our clients have always valued.
What’s new is the reach: new tools, new audiences, and new ways to connect with players, creators, and press around the world.
And we’re just getting started. The next wave of updates will bring even deeper insights, smarter automation, and richer creative options all built to make modern publishing faster, smarter, and more connected than ever.
