Hi Nick. Agree on working on definitions. We’ve been working to understand Urbantech for a few years now, beginning with a broad definition of tech that makes cities better. So far, we’ve looked at this through 4 lenses

• built environment — includes, I think, your definition, which is mainly hard assets like buildings, roads, bridges, ports, etc.
• mobility — cities are defined, perhaps mostly, by how we get around and how our stuff (food, clothing, service delivery) gets to us.
• govtech — these are services (frequently) delivered by local or city governments, so leaves out a lot of important national or federal services.
• utilities — resource flows like water, energy, waste, etc.

The overlap with govtech in our mind is simply that it’s a subset. The intersection with civictech is more complex. We tend to think of civictech as the tech that enables collective action and decision-making. For example, if you are to decide on major investments in urbantech, often it’s civictech that is the key enabler.

Greatly appreciate the efforts to define and happy to continue this here or elsewhere.
