Board Member Bios

We have a small team of board members of the foundation. Here is a bit about each of them, including declarations of any other directorships and any substantial shareholdings.

Current Board


Kate Chapman began contributing to OSM in 2009. She is a cofounder of the Humanitarian OpenStreetMap Team (HOT), a non-governmental organization dedicated to helping support communities, governments and humanitarian responders in their utilization of OpenStreetMap in crisis response and contingency planning. She joined the OpenStreetMap foundation in 2009 and was elected to the OSMF board in September 2013. Kate is employed as the Chief Technology Officer of the Cadasta Foundation and also serves on Cadasta's Board of Directors.

Paul Norman joined the board in 2014. He develops and maintains key parts of rendering software. As well as being a developer he works map styles and cartography and tracking and resolving edits with problems in OpenStreetMap. He works for CartoDB as a software developer.


Mikel Maron is a programmer and geographer working for impactful community and humanitarian uses of open source and open data. He started with OSM in 2005.

Ilya Zverev has been mapping since 2010, but got tired, joined OSMF and moved on to other tasks: writing an OpenStreetMap news blog, recording podcasts, developing apps and plugins, and so on. He remembers when the motto of OSM was "have fun", and devotes his time to make the project more fun for regular mappers. Mappers have elected him to the Board in 2015, which made him the first Board member not from Western Europe or North America. He works for MAPS.ME, helping make a popular OpenStreetMap-based mapping application.


Martijn van Exel is an OpenStreetMap contributor, community organizer and local Chapter leader since 2007. He has been serving on the OpenStreetMap United States Board of Directors since 2011. He also contributes to OpenStreetMap as a mapper and developer. He works for US based Telenav as OSM project lead. He lives in Salt Lake City with his wife.


Peter Barth is an addict, interested in almost everything related to OSM and OpenSource. He joined OpenStreetMap in 2007. Besides mapping and development, he is a regular speaker on conferences and events, works with the Data Working Group, the Wochennotiz – the German weekly OSM news – and helps to translate for WeeklyOSM. He's been a member of the OSM Foundation since 2012 and joined the board 2015 with the goal to make the OSMF more transparent and appealing to the general community.


All board members are "directors" in the sense of the UK Companies Act. Even the person we designate "secretary" is not a "secretary" in the sense of the UK Companies Act.
