Commitment: Part-Time to Start (Founding Role, Equity-Based)
Compensation: Equity, with potential for salary post-funding
About Turnstile
Turnstile is a nostalgia-driven, early-stage startup built for collectors of live event memories — a mobile-first platform where users can upload ticket stubs, tag them with event details, and share memories, photos, and digital artifacts from the event. It's part digital museum, part social time capsule for superfans of concerts, sports, movies, and more.
Turnstile was a runner-up in a 2023 innovation competition and has since evolved into a working mobile app. The current version, built in Flutter by a solo non-technical founder, is now live on TestFlight and includes the following features:
-Image capture and upload for physical ticket stubs
-Event detail entry and stub archiving
-Persistent local storage of all uploaded stubs and metadata
-Gallery view of saved stubs (“My Stubs”)
-Social feed feature ("Tailgate") with dummy posts and user posts as they upload stubs
-Bottom navigation bar with sections for Profile, Add Stub, and “Tailgate” feed (MVP version live)
-Support for attaching artifact links, choosing event type, and entering story captions
Current State
-Built in Flutter (Dart) — current build running on iOS
-Distributed via Apple TestFlight to small group for beta testing
-Persistent stub storage implemented using local JSON storage
-Navigation, detail input, and image upload fully functional
-Initial UI/UX design in place with onboarding, username creation, gallery view, and grouping/filtering stubs by event type
Important Note on Tech Stack
The app was intentionally built in Flutter for early-stage prototyping and beta testing. We are fully open to a new technical direction and welcome your vision. As our Technical Cofounder, you’ll have the freedom to propose and implement a more scalable architecture, whether that means evolving the current Flutter build or transitioning to a new framework entirely. Your leadership will shape the infrastructure and technology choices as we prepare for public launch and long-term growth.
Vision & Roadmap
-Cloud-based storage and user accounts (e.g., Firebase or Supabase)
-Social feed ("Tailgate") where users can share and explore public stubs
-OCR-based stub scanning and autofill of event data (name, date, location)
-Commercial partnership integration with sports teams, movie studios, bands and more
-App Store release by end of 2025, post-beta phase
Who We’re Looking For
A technical cofounder or founding engineer who wants to own and scale the backend, cloud storage, and release pipeline. Someone excited by the idea of crafting an expressive, memory-based social platform from the ground up — with creative freedom and ownership.
Must-Have Skills
-Proficiency in Flutter and Dart (or willingness to work with/transition from it)
-Experience with iOS builds, certificates, provisioning, and TestFlight deployment
-Comfort setting up cloud backends (Firebase, Supabase, or custom stack)
-Data modeling and implementation of persistent storage and auth
-App debugging and packaging for production
Bonus Skills
-OCR/image processing (ML Kit, Tesseract, etc.)
-Social features: feeds, likes, comments, follows
-API integrations (Ticketmaster, Setlist.fm, etc.)
-Interest in fandom, memorabilia, sports, concerts, film or the like
-Past startup or technical leadership experience
Your Role
-Collaborate directly with founder to refine and implement roadmap
-Own backend infrastructure and cloud storage implementation
-Lead decision-making around scalability and long-term technical vision
-Implement user authentication and sync across devices
-Scale the app for public release and App Store submission
-Optionally mentor additional devs as team grows
