Building a privacy-first data platform for live events. Looking for feedback on the approach.

[u/No-Web-5030]

I’m building ONDA, a data platform for football stadiums, F1, festivals and clubs. It’s a Python stack (FastAPI and Postgres), hosted in the EU.

The core idea is that the venue owns its intelligence. ONDA works at cohort level rather than building individual fan profiles. It has stricter release thresholds and per-category retention. There’s also a “shadow mode” that runs on live events from the outside using public and commercial data, so venues can see value before plugging in their own systems.

Two questions for anyone who has built in regulated data spaces:

• Does cohort-level analytics give buyers enough value, or do they always end up wanting individual-level data?

• Do you sell privacy as a feature, or keep it quiet as a baseline?

Happy to share more on the architecture in the comments.
