Withso builds Mapsmith and JurisField, geospatial software for teams that work with places.

We are a technology company in Chennai. We build products and custom software for organisations whose work depends on location: where things are, which area a task belongs to, and what changed on the ground.

Mapsmith is a web GIS for bringing in spatial data, making maps, running analysis and publishing dashboards. JurisField turns that geography into offline-ready field assignments and returns every record with its location and evidence. Around both, we design and build GIS applications from data model to deployment.

Custom GIS development, from data to deployment

Not every spatial problem fits an off-the-shelf product. We design and build GIS applications around an organisation’s own data, users and infrastructure: the data model and PostGIS services underneath, the web maps and APIs on top, and the field apps that keep records flowing back.

Initiatives beyond our products

The same engineering supports two independent efforts: one for citizens in Tamil Nadu, and one for the developers who build software every day.

Social impact

NammaTN

An independent civic platform for Tamil Nadu. Citizens report local issues in Tamil or English, neighbours verify them, and community-confirmed fixes are tracked in the open. NammaTN is not a government grievance portal.

Developer productivity

Zeros

An open-source, local-first macOS app for running coding agents against real repositories. Each workspace is an isolated Git worktree with its own conversation, terminal, preview and review surface.
