Open Knowledge Belgium is organising the 7th edition of its open Summer of code in July.

Every week we will invite one guest speaker to come by during lunch and talk about a topic he or she is passionate about.

We're excited to welcome Toon Vanagt - Open Knowledge Belgium's chairman and chronic entrepeneur - on July 19th. Toon will talk about the lean startup methodology.

Toon has been a startup entrepreneur since 1999. His latest ventures are data.be (structuring Belgian business information from official sources) and lex.be (full text search in millions of legal publications). Both these freemium businesses are build on unstructured data and heavily relying on open data. Toon is a strong believer of all things open, which he supports via the non-profit Open Knowledge Belgium.

This lunch talk will take place at BeCentral, Belgium's new digital hub in the heart of Brussels. Feel free to join us - it's free and open to everyone!
