Six doors, one company.

Everything we do on Roblox. Open a door.

Studio · Rival Ducks

We make Roblox experiences.

We design, build and operate Roblox experiences with the whole company behind each one: a full-stack team from concept to LiveOps, economies simulated in Codex before release, art from Asset Blox, Pintail inside every experience from the first session, Radar on the market. We ship, we operate, we measure, and we keep the numbers public.

What that covers
Publishing · Rival Ducks

We take games from build to launch.

Publishing is for games that have not shipped yet. We come in months before launch with development support, mentorship, a launch plan and the advertising budget behind it, and we bring the whole pipeline: Codex to balance the economy before release, Asset Blox for the art, Radar and Creator Discovery to pick the moment and the creators, Pintail inside the game from the first session. Revenue share, no upfront fee.

What that covers
  • PublishingDevelopment support, launch and growth for games that have not shipped yet, on a revenue share.
  • Creator ServicesMentorship, monetization design, art, localization and QA for studios still building.
Advertising · Rival Ducks

Growth for games that are already live.

Advertising is for games already on the platform. Our advertising network — sponsored placements, in-experience campaigns and the creators Creator Discovery finds first — takes a live game to the players it has not reached yet, planned on Radar's public data and reported week by week against live players and retention. The same network works the other way: brands that want to be on Roblox are matched with the experiences that fit them, and we build and run what they need there.

What that covers
  • AdvertisingUser acquisition and in-experience campaigns for live games, across our own advertising network.
  • Brand PartnershipsBrands onto Roblox: matched with the right experiences, built, integrated and activated.
Investment · Rival Ducks

We buy into games that are already working.

We take a stake in Roblox games that are already live and earning, and then we put the whole company behind them: development support, our advertising network, monetization design, LiveOps and every tool we run — Pintail inside the game, Codex on the economy, Radar and Creator Discovery on the market. We are operators, so diligence runs on our own data and on playing the game.

What that covers
  • InvestmentA stake in games already live and earning, backed with development, advertising and monetization support.
  • Consulting & AdvisoryDue diligence and strategy for investors and companies entering Roblox.
Tools · Rival Ducks

Software for the Roblox economy.

We built the tools we needed and then kept building: Radar, which reads the whole platform every minute and is free for everyone; Asset Blox, which turns a brief into finished game art; Creator Discovery, which finds every Roblox creator across TikTok, YouTube, Instagram, Twitch and Discord; Codex, which simulates a game's economy before it ships; and Pintail, the telemetry inside every experience we run. Radar is open to all, Asset Blox by application, the data underneath through the enterprise API. The rest is ours.

What that covers
Community · Rival Ducks

The community that builds Roblox.

Roblox is built by people, and the people who build it best know each other. We run a developer network of scripters, builders, artists and animators, put on jams, showcases and the Rival Ducks Awards, publish the guides nobody else writes down, and feed all of it with what our own tools see: which genres are rising, who is breaking out, what a launch actually needs. Free, and open to anyone who builds.

What that covers
  • Talent & CommunityA developer network — scripters, builders, artists — with game jams and placements.
  • EventsShowcases, awards and community meetups.
  • EducationGuides, courses and a newsletter on building and growing on Roblox.

Radar — the platform overview, live
Radar · Rival Ducks
Public · free, for good

Radar

The whole of Roblox, measured every minute.

Radar reads every public experience on Roblox around the clock — millions of universes, tiered by momentum so the ones that matter are polled every sixty seconds — and keeps every reading forever. Rankings, trending, per-country charts, genre momentum, creator portfolios, breakout detection, alerts: the complete picture of the platform, open to everyone, with no paywall and no tier.

Asset Blox — the icon studio
Asset Blox · Rival Ducks
Private beta · by application

Asset Blox

Game art, produced to a brief.

Asset Blox turns a brief into finished game art in the Roblox look: icons, 16:9 thumbnails, character concepts, VFX, animation and 3D models, generated against a studio’s own style anchors so every asset lands on-brand. It ships our games’ art first; access opens to selected studios by application.

Creator Discovery — a wall of creator feeds
Creator Discovery · Rival Ducks
Internal · in use across Rival Ducks

Creator Discovery

Every Roblox creator, found and followed.

Creator Discovery scans TikTok, YouTube, Instagram, Twitch and Discord end to end, finds every account and community making Roblox content, files each one by platform, format, genre and audience, and follows their numbers live — views, velocity and the games they move — so our publishing, advertising and investment desks reach the right creators before anyone else does.

Codex

Design, balance and simulation, before anything ships.

Codex is the console every piece of our games is authored in — characters, rarities, auras, upgrades, quests, prices — and the engine that proves the design before a player sees it. Every change runs through Monte Carlo simulation of the full player journey: millions of synthetic sessions against the live configuration, with the odds curves, luck stacks, drop distributions, time-to-kill, sink-and-source economy loops and progression pacing measured end to end. The game reads its configuration from Codex; nothing ships that the simulation has not passed.

Pintail

Live telemetry, analysed by AI, acting inside the game.

Pintail follows close to a thousand signals per player in real time — every session, event, purchase, path and hesitation — into our own ClickHouse, where models read the stream as it arrives. It segments players as they play, predicts churn and spend, and answers with personalised offers, tuned difficulty and timed content, while hundreds of in-game experiments run at once and settle on the metric that matters: retention.

Why we build on Roblox.

Roblox is not a game. It is the place where a generation meets, plays and makes things together, and the only platform where a small team can put a world in front of millions of people in a single weekend. Every year it looks more like the internet did at the start: enormous, fast, mostly unmeasured, and full of people building the future of play without waiting for permission.

We think it deserves better instruments. Most decisions on Roblox are still guesses: which genre is rising, whether a launch worked, what a chart position is worth, who the players actually are. So we built Radar to read the whole platform, every minute, and we gave it away. Free, for good, with the full history kept forever, because a market that can see itself makes better games.

We make our own games because judgement without shipping is theory. Operating Project: Aura every day, on our own tools, keeps us honest about what works, what players forgive and what they will not. Everything we offer other studios, we have used on ourselves first.

We publish, grow and invest in other people's games because the platform rewards whoever sees early, and we built the instruments that see early. The studio that has not shipped yet, the game that is live and stuck, the one that is earning and could earn more: each gets the same company behind it.

And there are things we will not do. We will not put a paywall in front of data. We will not delete history. We will not report a number we guessed. We are not affiliated with Roblox Corporation, and we intend to stay independent of the studios we measure, so that what Radar says is what the data says.
