About Harbinger Explorer

Founder

Harbinger Explorer is built by Marc Cherier, a Databricks Certified Data Engineer and two-time World Economic Forum Hackathon winner. The product exists to make API data exploration fast and accessible — without forcing teams through weeks of integration work before the first useful query.

Vision

API connections shouldn't take a week. Ad-hoc analysis shouldn't require a Python environment.

We believe analysts and engineers should spend time on questions, not on plumbing — connecting sources, loading data, and iterating in SQL should feel immediate.

What we believe

  • Data exploration should be fast — from URL or file to query in minutes.
  • It should stay secure — sensible defaults for governance and encryption where data leaves your control.
  • It should be browser-based where it helps — heavy lifting in the client with DuckDB WASM, fewer servers in the middle.
