VIB3S

How a Spanish startup built the go-to app for festival-goers — starting with zero users and zero budget

Summary

VIB3S is a Spanish app designed for music festival attendees — combining lineups, maps, schedules, shared plans and real-time updates in one place. The team started with a clear niche, iterated fast with direct user feedback from festival communities, and built a product that festival-goers actually open during the event.

What worked

  • Community-first GTM in festival Facebook groups and WhatsApp — zero paid acquisition in year one
  • Radical scope discipline — cut ticketing, artist bios, and generic event features to stay festival-only
  • Word-of-mouth loop at physical events — thousands of people together naturally share app recommendations

What failed

  • Initially tried to cover too many event types — concerts, clubs, sports — before cutting back to festivals only
  • Underestimated the seasonal nature of the business — revenue and usage peaks sharply in summer

The full story

VIB3S was born from a simple frustration: every summer, millions of festival-goers juggle four different apps, screenshot lineups, and lose their friends in the crowd. The founders had attended dozens of festivals themselves and knew the pain intimately.

The first version was intentionally minimal — a lineup viewer with a personal schedule builder. No maps, no social features, no notifications. Just the core: "What time does my favourite artist play, and where?" That first version launched at a single festival. Feedback was direct and fast: users wanted to share their schedules with friends. The social layer came in version 2.

The go-to-market was community-first. Rather than paid acquisition, the team joined every Spanish festival Facebook group and Reddit thread, offered the app for free to early adopters, and collected feedback in WhatsApp groups. The word-of-mouth loop at festivals — where thousands of people are physically together and naturally share recommendations — gave them an organic growth channel that paid ads could never replicate.
