DeepReach refers to two main things: an AdTech platform for multi-location marketing (DeepReach.com) helping brands run local ads on Google, Facebook, etc., and a Deep Learning research method (DeepReach) for high-dimensional control problems, often used in autonomous systems like self-driving cars, notes the IEEE Xplore. There's also a less prominent AI evaluation platform called DeepReach.ai. The common thread is using advanced tech (AI/Deep Learning) to solve complex, localized, or large-scale challenges in advertising or robotics.
