Upstream Partners is an independent software studio. We design, build, and operate mobile apps, games, and data products, from first prototype through release and ongoing support.
Food tracking app for structured medical diet programs. Servings-based tracking with healthcare provider reporting. Live on App Store and Google Play.
A tile-chaining puzzle game on the App Store and Google Play, with a daily shared-board edition on Reddit: everyone plays the same board once a day and competes on a per-day leaderboard inside the post.
A multiplayer "spot the AI" game: two images, one generated, and players race to find the fake. Party, solo, and marathon modes on web and mobile, backed by a curated multi-model image pipeline.
Community rankings and tier lists with tap-to-vote ballots. Players rank the whole field, then see where they disagree with the crowd. Runs natively inside Reddit communities and on the web, no signup needed.
A protein-first food diary built for GLP-1 users. Log a meal in two taps and track protein, weight, shots, and side effects. No account, no cloud, no ads: data stays on the device.
Open-source development pipeline for AI coding agents. Every stage (idea, spec, plan, build) is reviewed by a second provider, Claude Code and Codex checking each other's work, and nothing merges without a GO.
Upstream Partners LLC builds and runs its own software products across mobile, web, and community platforms. Each product is taken end to end: design, engineering, release, and the analytics and iteration that follow.
The studio works across native and cross-platform stacks, choosing the tools that fit the product rather than the other way around. Several titles are live on the App Store and Google Play today.
