About Santtu Pyykkönen
I work with GIS, spatial data, and open source tools. My background combines hands-on technical work, consulting, and sales.
About Me
I work with geospatial data, open source GIS, and the messy space between technical work and business decisions.

Most of my career has been in open source GIS. I have worked with municipalities, public sector organizations, and companies that need better ways to manage spatial data, analyze it, or turn it into something operational.
What makes my background a bit unusual is that I have done this work from several angles. I have been a GIS consultant, project manager, trainer, sales lead, and board member. So I am comfortable both in the technical details and in the conversations where someone is trying to decide whether a GIS investment is actually worth doing.
What I Actually Do
I usually help with one of these:
- spatial analysis for decision-making
- PostGIS, QGIS, GeoServer, and related open source GIS tooling
- data workflows and integrations
- scoping and shaping GIS projects so they stay practical
- translating between technical teams, domain experts, and decision-makers
I am especially interested in work where the analysis has a real consequence. That could mean a municipality deciding how to organize services, a team trying to improve its data pipeline, or a client trying to understand where the real bottleneck is before buying more software.
Background
I have spent more than ten years at Gispo in different roles, from consultant work to sales leadership. At the same time, I have tried to stay close to the technical side instead of moving away from it completely. I still like working with data, maps, and the actual structure of a problem.
Before that, I worked in Mexico in research and public-sector contexts. That period shaped a lot of how I think. It taught me to look at geography not just as a technical layer, but as something tied to inequality, access, mobility, and public decisions. It also gave me long-term working Spanish, which still turns out to be useful.
How I Work
I am not very interested in GIS for its own sake. I am interested in whether it helps someone make a better decision, build a better process, or understand a situation more clearly.
That usually means starting with plain questions:
- What is the real decision behind this?
- What data is actually good enough to use?
- What level of accuracy matters here?
- What should stay simple, and what is worth modeling properly?
I tend to prefer pragmatic solutions over impressive ones. A modest analysis that changes a real decision is usually more valuable than a complicated setup that no one will maintain.
Speaking and Writing
I write here about GIS, spatial analysis, open source tools, and the kinds of strategic questions where geography matters. Some posts are technical. Some are case-study style. Some are closer to working notes.
I have also spoken at events like FOSS4G about open source geospatial work and enterprise GIS topics.
