Built with Claude Code · The Playground

This project started as a pretext.

A pretext to explore Claude Code — Anthropic's AI development tool — on a real project with real constraints. A few days later, I had a working MVP. A few weeks later, a full platform in production — with real communities, events, and users.


The problem

I've been running community events for years. And for years, I've hit the same wall.

There's no tool that does community + events + free + good UX + audience ownership all at once.

Meetup

Good community model, but dated UX and organizer paywall.

Luma

Clean experience, beautiful event pages. But every event is an island — no retention.

DIY tools

Google Forms + Eventbrite + WhatsApp + spreadsheets. You get by, but you lose your audience.


The answer

The Playground starts from a simple idea.

  • The community is the core entity — not the event.
  • The event is a viral entry point.
  • Joining an event automatically makes you a community member.
  • The community persists between events.

Meetup's community model + Luma's experience + 100% free. No subscription, no platform commission.

About me

I'm Dragos Dreptate. Executive, entrepreneur and coach — 25 years in tech, based in Paris. I founded The Spark, a consulting firm specializing in AI, Product and Innovation.

For years, I've been running events — product conferences, masterclasses, internal events and agile community meetups. That experience as an organizer, running into the same broken tools over and over, is what sparked The Playground.
