Case study · Creator marketplace app

ANNO Creative

ANNO CREATIVE is a three-sided marketplace from a São Paulo content agency. Verified models and creators get experiences at restaurants, bars, gyms, and salons, or product kits from brands, in exchange for verified Instagram content and a Google review. We built the mobile app, the backend, and the website.

The brief

What the client needed.

A barter marketplace only works if both sides trust it. Venues need to know the creator actually showed up and actually posted. Creators need to know the offer is real. The agency in the middle needs to approve who gets in and see everything that happens.

So most of the engineering went into verification rather than screens: proving a visit happened, proving content was delivered, and enforcing the rules automatically when it was not.

What we built

  • iOS app built with Expo and React Native, live on the App Store
  • Creator flows: application with portfolio photos, explore, offer detail, booking, check-in, content delivery, profile, and member card
  • Venue panel and brand panel, including product-kit campaigns with shipment tracking
  • In-app admin for users, reservations, posts, and support
  • Managed database backend: Postgres, authentication, storage, realtime, edge functions, and scheduled jobs
  • Instagram and Google reviews integrations, push notifications, maps, and over-the-air updates
  • Marketing website in Brazilian Portuguese with separate journeys for creators and partners, structured data, and a sitemap
Worth a closer look

The details that matter.

  • Check-in that cannot be faked from home

    Check-in is verified on the server: only the creator’s own reservation, only inside the booking window, only close to the venue’s pin, and mocked locations are rejected. The venue is notified in real time.

  • Deliverables with proof

    Every visit has a defined set of deliverables, stories, a Reel, a Google review, and each one needs its own proof before the visit counts as complete.

  • Rules that enforce themselves

    No-shows, late cancellations, and missed content deadlines are checked on a schedule and turned into strikes, suspensions, and expiries without anyone doing it by hand.

  • Curation at every step

    The ANNO team approves every creator, every venue, every new portfolio photo, and every deliverable from review queues inside the app.

  • Kits for brands without a venue

    Brands ship product kits to creators, and the campaign tracks each one from sent to delivered to posted to verified.

  • A membership that feels like one

    A gold member card with an animated sheen and tier progression, where the top tier sees offers a day early.
