# Smart building IoT platforms

> IoT + AI for commercial buildings — HVAC, lighting, security, energy.

**Sector**: [PropTech](https://signals.gitdealflow.com/niche-down/proptech)  
**Build cost**: Team-sized build  
**Deal velocity**: Trickle — one deal per quarter

## Why now

Energy + ESG pressure makes smart-building tech a budget line. Most building-management systems are 90s-vintage.

## What the signal looks like

Repos with BACnet / Modbus adapters, AI-control libraries, and building-management integrations.

## Public examples

*Public projects + categories only — we never name founders tracked inside the paid product.*

- 75F shape
- Switch Automation
- Open-source building-IoT libraries

## What this displaces

A BMS from 2003 + a manually adjusted thermostat.

## Our build-vs-invest call

Capital + hardware-heavy. Fund only with building-industry background. The moat is the integration breadth + the AI savings.

## Frequently asked

### Buyer?

Commercial property owners + property managers.

### Pricing?

Per square foot per year.

### Defensibility?

Integration + AI accuracy.
