JustAir is a startup that operates in the environmental technology sector, specifically focusing on air quality monitoring. The company provides a platform that offers real-time data on air quality, enabling communities to stay safe and informed. The data gathered by JustAir's tools can also be used to drive change and improve air quality in the long term.

JustAir's primary clients are local leaders and community groups who are concerned about air quality and environmental justice. The company works closely with these groups to understand their specific needs and concerns, and uses this information to guide their monitoring efforts.

JustAir's business model is centered around providing neighborhood-level air quality mapping, monitoring, and visualization. The company makes money by partnering with cities, community groups, and corporate partners to expand their air quality monitoring network. They also offer services to communities that already have air quality monitors, helping them to better understand and utilize their data.

In addition to monitoring, JustAir also empowers communities with the data they collect. This data can be used to engage local authorities, spark conversations about air quality, and create policies that make the air safer to breathe.

JustAir is currently partnering with several organizations in Grand Rapids and Detroit to expand their air quality monitoring network. These partnerships demonstrate the company's commitment to environmental justice and their ability to collaborate with a variety of stakeholders.
