We believe businesses with physical spaces can only truly thrive when they harness real-world foot traffic data to make better operational decisions.

We created the world’s first battery-powered, thermal-sensing people counter run on a cellular network so that organizations could optimize their operations with more reliable and less expensive data about how their spaces are used. Our ever-evolving foot traffic analytics platform is helping our growing user community of retailers, facilities professionals and nonprofits measure their success.

Michael Brand, Founding CEO

Michael Brand co-founded Dor with Gregg Golembeski to create a people counting solution that was more affordable and more accurate than available solutions, solving for an urgent, unmet need for independent and enterprise retailers alike. In 2017, Michael led the company to 30 percent month-over-month customer growth and raised a seed round of $3.7 million. He heads Dor’s growing team as they continue to empower organizations with the data they need to make more proactive operational decisions. Before Dor, Michael was a founding team member and engineering lead at the nutrition analytics startup MarkOne, and a hardware engineer on the iPod team at Apple. He spends his spare time mentoring startup founders.
