Polytech Ecosystem Ventures-backed BlueFox has collected $7m in series A capital from investors including Panasonic.

BlueFox, a US-based company developing customer engagement services for brands and retailers, has raised $7m in its series A round from a consortium including electronics maker Panasonic and technology services platform Pentalog.

Venture capital firms Baseline Ventures and NewGen Capital also contributed to the round.

Founded in 2016, BlueFox operates a cloud platform to measure foot traffic and customer engagement in physical locations. The technology relies on sensors that detect smartphone signals rather than Bluetooth beacons that are traditionally used.
